            <p> GENUS  RYUTHELA HAUPT, 1983</p>
            <p> Diagnosis:  Ryuthela males can be distinguished from all other Heptathelinae genera by lacking the conductor and by the contrategulum with an elongated spine (i.e. Fig. 8A, C, E). The females differ from  Heptathela ,  Qiongthela ,  Sinothela ,  Songthela and  Vinathela by one pair of receptacular clusters close to each other (i.e. Fig. 5A–V), located at the anterior margin of the bursa copulatrix, and from  Ganthela by receptacular clusters without stems (Xu et al., 2015b).  Ryuthela body length varies from 6.5 to 14.5 mm, and  Ryuthela species can have seven or eight spinnerets. </p>
            <p> Distribution:  Ryuthela species are restricted to Ryukyu archipelago and are found from central Ryukyus (Okinawa group) to southern Ryukyus.  Ryuthela species on central Ryukyus share habitats with  Heptathela species (Xu et al., 2016). </p>
            <p> Composition: After this revision,  Ryuthela contains 15 species. </p>
            <p>Remarks: Seven of the 15 delimited species with male and female specimens can be diagnosed from each other morphologically. For the other eight species without males, especially for those that are distributed on the same islands, the species-specific nucleotide changes in the standard DNA barcode alignment were used to augment insufficient morphological diagnoses.</p>

            </p>
            <p> Diagnosis: Male  R. nishihirai s.s. can be distinguished from all other  Ryuthela species by the contrategulum with sparse denticles on proximal margin (Fig. 5W). Females of  R. nishihirai s.s. differ from most other island  Ryuthela species by the short receptacular clusters that are close to each other, and further differ from the other species on Okinawajima island by detailed arrangement of the receptacular clusters. These are either fused into one group with obvious granula or form flat receptacular clusters separated from each other (Fig. 5L, P). However,  R. nishihirai s.s. can also be diagnosed from all other Okinawajima island  Ryuthela species by the following unique nucleotide substitutions in the standard DNA barcode alignment: A (16), C (173), T (278), G (304), C (475), C (494), G (496), T (571). </p>
            <p>Description: Male (lectotype). Body colour somewhat faded. Carapace light yellowish brown with darker frontal margin and black ocular area; opisthosoma yellow, with beige tergites; sternum narrow, much longer than wide; a few long pointed hairs running over ocular mound in a longitudinal row; chelicerae robust with promargin of cheliceral groove with ten denticles of variable size; legs with strong hairs and spines; opisthosoma with 12 tergites, the first tergite forming the superior lorum of the pedicel, the 12th tergite forming the dorsal wall of the anal tubercle, the third widest; seven spinnerets. Measurements: BL 9.05, CL 5.25, CW 4.20, OL 4.20, OW 3.15; ALE&gt; PLE&gt; PME&gt; AME (left PME absent); leg I 17.10 (4.75 + 2.25 + 3.40 + 4.50 + 2.20), leg II 17.15 (4.50 + 2.25 + 3.20 + 4.95 + 2.25), leg III 18.80 (4.25 + 2.10 + 3.45 + 6.00 + 3.00), leg IV 23.90 (5.25 + 2.40 + 4.65 + 7.70 + 3.90).</p>
            <p>Palp. Prolateral side of paracymbium unpigmented and unsclerotized; numerous setae and spines at the tip of paracymbium (Fig. 5X). Prolateral contrategulum with a short and curved spine and sparse denticles on proximal margin (Fig. 5W); the distal part of contrategulum blunt (Fig. 5Y, Z); tegulum with a large smooth marginal apophysis (Fig. 5Y, Z); embolus with a narrow basal part (Fig. 5X, Z) (cf. Ono, 2009, p. 79, figs 26–29).</p>
            <p>Female. Carapace and opisthosoma brown; tergites slightly dark brown; a few long pointed hairs running over ocular mound in a longitudinal row; chelicerae robust with promargin of cheliceral groove with 13–15 strong denticles of variable size; legs with strong hairs and spines; opisthosoma with 12 tergites; 7 spinnerets. Measurements: BL 9.75–13.92, CL 4.85–6.30, CW 3.80–5.80, OL 5.82–7.28, OW 4.10–5.92; ALE&gt; PLE&gt; PME&gt; AME; palp 10.11 (3.28 + 1.90 + 2.25 + 2.68), leg I 12.15 (3.72 + 2.12 + 2.25 + 2.58 + 1.48), leg II 11.76 (3.55 + 2.13 + 2.03 + 2.55 + 1.50), leg III 12.59 (3.53 + 2.18 + 2.05 + 3.05 + 1.78), leg IV 18.82 (5.21 + 2.43 + 3.25 + 5.18 + 2.75).</p>
            <p>Female genitalia. A pair of receptacular clusters along the anterior margin of bursa copulatrix; in the dorsal view, their basal parts close to each other (Fig. 5A–D, K–L, Q–S) or fused to form one large receptacular cluster with obvious granula (Fig. 5I–J); with a high intraspecific variation in the shape and number of the receptacular clusters.</p>
            <p>Distribution: Okinawajima island (Asato, Chibana and Shuri), Okinawa Prefecture, Japan.</p>
            <p> Remarks: Tanikawa (2013a) considered all species on Okinawajima island as  R. nishihirai s.l. , but based on our exhaustive collection on Okinawajima island, results from an integrative analysis of the geographic distribution, phylogenetic and population genetic data, and distinct barcoding gaps in the genus  Ryuthela (5.6–6.7% for K2P and 5.3–6.3% for p -distance), we propose seven  Ryuthela species on Okinawajima island, including  R. nishihirai s.s. Since the holotype locality of  R. nishihirai s.l. is Shuri, Okinawajima island (Haupt, 1979), we treated the specimens collected from the southern part of Okinawajima island (from Chibana to the south Okinawajima island) as  R. nishihirai s.s. We examined the syntype series of  R. nishihirai deposited at NSMT. According to the remarks in Dunlop, Steffensen &amp; Ono (2014, p. 39), we designated the male specimen deposited at NSMT from syntype series as the lectotype because it is important for describing and classifying all other new species on Okinawajima island. Female genitalia of  R. nishihirai s.s. are highly variable. The fused receptacular clusters may be caused by a physical moment at forming their female genital instead of variation; however, we considered them as variation in this study. </p>

            <p>Etymology: The species epithet, a noun in apposition, refers to the type locality.</p>
            <p> Diagnosis: Male  R. motobu sp. nov. can be distinguished from  R. nishihirai s.s. by the short and curved contrategular spine (Fig. 8A, C, E); from  R. iheyana by the larger marginal apophysis of tegulum (Fig. 8C–E); from other  Ryuthela species by the short and blunt distal contrategulum, and the narrow basal part of embolus (Fig. 8B, D, E). Females of  R. motobu sp. nov. can be distinguished from  R. henoko sp. nov. by the receptacular clusters with bases separated from each other and from the other Okinawajima island species by the receptacular clusters that are longer than their width (Fig. 8F–N). However,  R. motobu sp. nov. can also be diagnosed from  R. nishihirai s.s. by the following unique nucleotide substitutions in the standard DNA barcode alignment: G (1), T (16), C (26), A (58), C (76), T (109), C (115), G (119), A (157), A (160), T (173), G (181), C (239), G (241), T (247), C (256), A (278), A (304), C (313), C (332), T (337), T (343), T (352), G (358), A (445), T (475), C (484), T (494), A (496), T (533), G (535), C (571), T (577), C (592), T (601), C (604), G (607), G (619) and differs from all other  Ryuthela species on Okinawajima island by the following unique nucleotide substitutions in the standard DNA barcode alignment: A (58), C (76), G (181), T (337), T (533), G (535), G (619). </p>

            <p> RYUTHELA IHEYANA ONO, 2002</p>
            <p> Ryuthela iheyana Ono, 2002, p. 52 , figs 1–3 (description of female); Ono, 2009, p. 80, figs 1, 7–8; Tanikawa, 2013a, p. 34, figs 2D–F, 3D–F, 4D–F, 5, 6A–E (description of male). </p>
            <p>  Holotype:  Female deposited at NSMT (NSMT-Ar 5185), from Mt. Gayozan, NE slope, 50 m a.s.l., Iheyajima island, Okinawa Prefecture, Japan, 20 January 1998, by H. Ono; examined. </p>
            <p>Other material examined: Male (XUX-2014-067) and female (XUX-2014-068), collected at forest trail, Mt. Koshi dake, Iheyajima island, Okinawa Prefecture,</p>
            <p> Japan, 27.04°N, 127.97°E, 10 May 2014, by D. Li and B. Wu . </p>
            <p> Diagnosis: Male  R. iheyana can be distinguished from  R. motobu sp. nov. by the straight contrategulum spine and the narrower marginal apophysis of tegulum and from all other  Ryuthela species by the short and straight contrategulum spine (Fig. 12D–F, J) and the rather sharp distal part of contrategulum (Fig. 12E, G), as well as the wider and blunt terminal apophysis of tegulum (Fig. 12F, J). Females of  R. iheyana can be distinguished from  R. sasakii and  R. nishihirai s.s. by the bar-shaped receptacular cluster (Fig. 12A–C).  Ryuthela iheyana can also be diagnosed from all other  Ryuthela species by the following unique nucleotide substitutions in the standard DNA barcode alignment: G (2), G (5), G (32), C (68), A (95), T (107), C (112), T (199), T (217), G (307), C (373), T (388), C (397), T (580), C (586). Description: Male. Carapace and opisthosoma light brown; tergites dark brown; sternum narrow, nearly twice as long as wide; a few long pointed hairs running over ocular mound in a longitudinal row; chelicerae robust with promargin of cheliceral groove with 11 vestigial denticles of variable size; legs with strong hairs and spines; opisthosoma with 12 tergites, close to each other, the first 2–5 larger and the fifth largest; 7 spinnerets. Measurements: BL 9.40, CL 4.80, CW 4.00, OL 5.20, OW 3.70; ALE&gt; PLE&gt; PME&gt; AME; leg I 14.05 (3.90 + 1.70 + 2.75 + 3.70 + 2.00), leg II 14.45 (3.78 + 1.75 + 2.85 + 4.07 + 2.00), leg III 15.53 (3.70 + 1.70 + 2.88 + 4.75 + 2.50), leg IV miss. </p>
            <p>Palp. Prolateral side of paracymbium unpigmented and unsclerotized, numerous setae and spines at the tip of paracymbium (Fig. 12D); contrategulum with a short and straight spine and numerous denticles on proximal margin (Fig. 12D–F, J); in the ventral view, the distal part of contrategulum sharp (Fig. 12E, G); the terminal apophysis of tegulum is wide and blunt in retrolateral view (Fig. 12F, J); embolus with a narrow basal part (Fig. 12F).</p>
            <p>Female. Coloration similar to that of male; chelicerae robust with promargin of cheliceral groove with 14 strong denticles of variable size; legs and opisthosoma as in the male; 7 spinnerets. Measurements: BL 12.70, CL 5.70, CW 5.00, OL 6.40, OW 4.70; ALE&gt; PLE&gt; PME&gt; AME; palp 9.83 (3.10 + 1.70 + 2.28 + 2.75), leg I 11.70 (3.46 + 1.95 + 2.36 + 2.50 + 1.43), leg II 11.45 (3.45 + 2.00 + 2.00 + 2.50 + 1.50), leg III 12.68 (3.10 + 2.90 + 2.00 + 3.00 + 1.68), leg IV 17.50 (5.00 + 2.25 + 3.10 + 4.65 + 2.50).</p>
            <p>Female genitalia. Fused receptacular cluster forming a bar with a very short genital stalk (Fig. 12A–C).</p>
            <p>D i s t r i b u t i o n: I h e y a j i m a i s l a n d, O k i n a w a Prefecture, Japan.</p>
            <p> Remarks: Based on Tanikawa’s (2013a) description, the female genitalia of  R. iheyana show high intraspecific variation comparable to other species. </p>

                <a title="Search Plazi for locations around (long 127.35/lat 26.17)" href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=127.35&amp;materialsCitation.latitude=26.17">Aharen</a>
                 , Tokashikijima island, Okinawa Prefecture, Japan, 26.17°N, 127.35°E, 50 m a.s.l., 22 December 2012, by D. Li, F. X. Liu and X. Xu  . 
            </p>
            <p> Diagnosis: Females of  R. owadai differ from all other  Ryuthela species by the relative length of receptacular clusters (these are slightly longer than wide; Fig. 13A– L); the female genitalia are morphologically similar to  R. sasakii , but the length of the receptacular clusters is shorter than that of  R. sasakii . Moreover,  R. owadai can also be diagnosed from  R. sasakii by the following unique nucleotide substitutions in the standard DNA barcode alignment: T (10), A (22), A (43), C (163), C (211), C (239), T (241), T (271), T (322), C (343), T (352), T (361), T (364), T (367), C (370), T (415), T (454), A (470), T (502), T (541), G (544), C (601), C (610), C (622). </p>
            <p>Description: Female. Carapace and opisthosoma yellow brown; tergites darker brown; sternum narrow, nearly twice as long as wide; a few long pointed hairs running over ocular mound in a longitudinal row; chelicerae robust with promargin of cheliceral groove containing 12–14 vestigial denticles of variable size; legs with strong hairs and spines; opisthosoma with 12 tergites; 7 spinnerets. Measurements: BL 6.80– 10.50, CL 3.50–5.18, CW 2.98–4.20, OL 3.48–5.85, OW 2.60–4.20; ALE&gt; PLE&gt; PME&gt; AME; palp 5.98 (2.05 + 1.08 + 1.30 + 1.55), leg I 8.63 (2.50 + 1.43 + 1.55 + 1.50 + 1.65), leg II 8.29 (2.43 + 1.50 + 1.45 + 1.73 + 1.18), leg III 8.59 (2.40 + 1.37 + 1.35 + 2.15 + 1.32), leg IV 11.89 (2.97 + 1.78 + 2.10 + 3.21 + 1.83).</p>
            <p>Female genitalia. A pair of receptacular clusters with the basal parts separated or fused together and with the distal part heart shaped (Fig. 13D, F); the opening part of receptacular clusters is located at the ventral part of bursa copulatrix, but visible in the dorsal view (Fig. 13A–L).</p>
            <p>D i s t r i b u t i o n: To k a s h i k i j i m a i s l a n d, O k i n a wa Prefecture, Japan.</p>
            <p> Remarks: Tanikawa (2013a) considered  R. owadai as synonym of  R. sasakii based on the lack of distinct morphology to distinguish them. Although we only collected females whose genitalia are highly variable as in other  Ryuthela , the results from other data sources support the validity of  R. owadai . </p>

            <p> Diagnosis: Males of  R. sasakii differ from other  Ryuthela species by the bifurcated tip of the embolus (Fig. 14C, D, F) and longer contrategulum (Fig. 14E); they can be distinguished from  R. motobu sp. nov. by the longer contrategular spine (Fig. 14C, F); from  R. iheyana by the curved contrategular spine (Fig. 14C, F); and from species on Ishigakijima island by the shape of the contrategulum (Fig. 14C, E, F). Females of  R. sasakii can be distinguished from  R. owadai by the longer and slender receptacular clusters (Fig. 14G–R).  Ryuthela sasakii can also be diagnosed from  R. owadai by the following unique nucleotide substitutions in the standard DNA barcode alignment: A (4), G (10), A (19), T (43), T (163), T (211), A (238), T (239), A (241), A (250), C (271), A (292), T (319), A (322), C (352), A (355), C (361), C (364), C (367), T (370), T (383), C (415), T (433), G (470), T (475), C (502), T (524), A (541), A (601), T (610), T (622). </p>

                 dake, Ishigakijima island, Okinawa Prefecture, Japan, 24.40°N, 124.24°E, 75 m a.s.l., 10 July 2013, by D. Li and B. Wu  . 
            </p>
            <p> Diagnosis: Male of  R. ishigakiensis s.s. is similar to  Ryuthela banna sp. nov. and  Ryuthela hirakubo sp. nov. (see below for the description), but it can be distinguished from  R. banna sp. nov. by the long and curved contrategular spine and the fusion of the inner serrate margin of the upper edge and the lower edge at the distal part of contrategulum (Fig. 15A, C, E); from  R. hirakybensis sp. nov. by the curved contrategular spine and the sharp lower edge of contrategulum (Fig. 15C, E); and from other  Ryuthela species by the contrategulum with two edges (Fig. 15C, E) and the wide separation of tegulum from contrategulum (Fig. 15C, E). Female genitalia of  R. ishigakiensis s.s. lack diagnostic characters from other species on Ishigakijima island and Iriomotejima island (Fig. 15F–K). However,  R. ishigakiensis s.s. can be diagnosed from all other  Ryuthela species on Ishigakijima island and Iriomotejima island by the following unique nucleotide substitutions in the standard DNA barcode alignment: C (7), G (16), C (139), C (154), T (188), C (220), T (331), C (343), C (379), G (385), T (454). </p>
            <p>Description: Male. Carapace and opisthosoma light brown; tergites darker brown; sternum narrow, nearly twice as long as wide; a few long pointed hairs running over ocular mound in a longitudinal row; chelicerae robust with promargin of cheliceral groove containing 10 vestigial denticles of variable size; legs with strong hairs and spines; opisthosoma with 12 tergites; 8 spinnerets. Measurements: BL 11.15, CL 5.70, CW 5.30, OL 5.50, OW 4.40; ALE&gt; PLE&gt; PME&gt; AME; leg I 15.10 (3.80 + 2.00 + 2.80 + 4.00 + 2.50), leg II 16.85 (4.70 + 1.35 + 3.50 + 4.40 + 2.90), leg III 15.90 (3.50 + 2.10 + 2.90 + 4.30 + 3.10), leg IV 23.15 (5.80 + 2.00 + 3.90 + 7.35 + 4.10).</p>
            <p>Palp. Prolateral paracymbium unpigmented and unsclerotized, numerous setae and spines at the tip of paracymbium (Fig. 15A); contrategulum with a long and curved spine, and with two edges, the upper edge with two margins (inner one with serrate margin and the outer one with smooth margin) and the lower edge (Fig. 15C, E); the distal part of the inner serrate margin fused with the lower edge (Fig. 15C, E); the terminal apophysis of tegulum blunt (Fig. 15C, E); embolus with a wide basal part (Fig. 15E). In retrolateral view, the terminal apophysis of tegulum located approximately at the middle basal part of embolus (Fig. 15C, E).</p>
            <p>Female. Coloration darker than that of male; chelicerae robust with promargin of cheliceral groove containing 12–16 strong denticles of variable size; legs and opisthosoma as in the male; 8 spinnerets. Measurements: BL 11.40–14.48, CL 5.88–7.80, CW 5.00–6.25, OL 6.50–7.65, OW 4.60–5.60; ALE&gt; PLE&gt; PME&gt; AME; palp 10.56 (3.64 + 1.82 + 2.30 + 2.80), leg I 12.40 (3.95 + 2.10 + 2.45 + 2.60 + 1.30), leg II 12.07 (3.60 + 2.10 + 2.25 + 2.67 + 1.45), leg III 12.52 (3.65 + 1.90 + 2.40 + 3.32 + 1.25), leg IV 18.20 (5.15 + 1.90 + 3.25 + 5.10 + 2.80).</p>
            <p>Female genitalia. A pair of receptacular clusters along the anterior margin of bursa copulatrix, basally separated from each other, cylinder shaped and granulated (Fig. 15G–H, J–K), or basally fused (Fig. 15F, I).</p>
            <p>Distribution: Ishigakijima island (Mt. Kara dake), Okinawa Prefecture, Japan.</p>
            <p> Remarks: The holotype locality of  R. ishigakiensis is at Mt. Omoto dake, which is located at the central Ishigakijima island (Haupt, 1983). Our specimens were collected at Mt. Kara dake at the eastern Ishigakijima island. We did not examine the holotype of this species, but based on male and female illustrations, we consider the specimens collected from Mt. Kara dake as  R. ishigakiensis s.s.</p>

            <p> Ryuthela tanikawai Ono, 1997, p. 157 , figs 19–20 (description of female); Ono, 2009, p. 80, figs 38–40; Dunlop, Steffensen &amp; Ono, 2014, p. 39 (removed from synonymy of  R. ishigakiensis , contra Tanikawa, 2013a, p. 38). </p>
            <p>  Holotype:  Female deposited at NSMT (NSMT-Ar 3484), from Urauchi, Iriomotejima island, Okinawa Prefecture, Japan, 30 March 1983, by A. Tanikawa; examined. </p>
            <p>
                 Other material examined:   Two females (XUX-2013- 200/206), collected at

                 , Iriomotejima island, Okinawa Prefecture, Japan, 24.35°N, 123.92°E, 30 m a.s.l., 8 July 2013, collected by D. Li and B. Wu. 
            </p>
            <p> Diagnosis: Females  R. tanikawai differ from all other  Ryuthela species except  R. ishigakiensis s.s. by short cylinder-shaped and granulated receptacular clusters, but cannot be morphologically diagnosed from  R. ishigakiensis s.s. (Fig. 19A–D). However,  R. tanikawai can be distinguished from all other  Ryuthela species on Ishigakijima island by the following unique nucleotide substitutions in the standard DNA barcode alignment: T (43), G (70), C (121), G (169), T (250), T (257), T (266), C (268), C (292), A (334), A (356), T (358), A (383), T (415), G (470), G (484), T (556). </p>
            <p>Description: Female. Carapace and opisthosoma dark brown; tergites darker brown; sternum narrow, nearly twice as long as wide; a few long pointed hairs running over ocular mound in a longitudinal row; chelicerae robust with promargin of cheliceral groove containing 13–15 vestigial denticles of variable size; legs with strong hairs and spines; opisthosoma with 12 tergites; 8 spinnerets. Measurements: BL 11.20– 11.50, CL 5.60–6.44, CW 4.38–4.70, OL 6.03–6.52, OW 4.31–4.40; ALE&gt; PLE&gt; PME&gt; AME; palp 10.47 (3.52 + 1.88 + 2.19 + 2.88), leg I 12.57 (3.90 + 2.20 + 2.30 + 2.68 + 1.49), leg II 12.47 (3.72 + 2.16 + 2.18 + 2.85 + 1.56), leg III 13.26 (3.78 + 2.18 + 2.22 + 3.18 + 1.90), leg IV 18.03 (5.43 + 1.80 + 3.30 + 5.00 + 2.50).</p>
            <p>Female genitalia. A pair of receptacular clusters along the anterior margin of bursa copulatrix, basally separated from each other, cylinder-shaped and granulated (Fig. 19B, D), or granulated receptacular clusters close to each other at the basal part (Fig. 19A, C).</p>
            <p>Male. Unknown.</p>
            <p>D i s t r i b u t i o n: I r i o m o t e j i m a i s l a n d, O k i n a w a Prefecture, Japan.</p>
            <p> Remarks: Ono (2009) indicated some differences in male palpal organ between  R. ishigakiensis s.l. and  R. tanikawai based on specimens and photographs made by Haupt (2003). Contrary to this, Tanikawa (2013a) considered  R. tanikawai as the synonym of  R. ishigakiensis based on the lack of distinct male and female morphology to distinguish between them. In this study, we collected only two females and no males. Considering highly variable female genitalia in  Ryuthela , we base our revalidation of  R. tanikawai on other data sources. </p>
