Type material.

Holotype. China • male; Hainan Prov., Lingshui County, Diaoluoshan Mountain ; 916 m; 16 Apr. 2015; Lu Qiu & Qi-Kun Bai leg.; SWU-B-BB100101 .

Paratypes. China • 1 male & 2 females; same collection data as holotype; 18 Apr. 2015; SWU-B-BB100102 to 100104 • 1 female; Hainan Prov., Wuzhishan Nature Reserve ; 795 m; 18 May 2014; Xin-Ran Li, Shun-Hua Gui & Jian-Yue Qiu leg.; SWU-B-BB100105 • 1 female; Hainan Prov., Diaoluoshan Mountain ; 275 m; 25 May 2014; Xin-Ran Li, Shun-Hua Gui & Jian-Yue Qiu leg.; SWU-B-BB100106 .

Differential diagnosis.

The new species readily differs from all its congeners in the spination of hind tarsi. Cyrtonotula epunctata sp. nov. resembles C. lata Hanitsch, 1929 in testaceous body color and the length of hind metatarsus, but the new species can be distinguished from C. lata by the following characters: the coloration of facial part black, with clypeo-labral area yellowish brown, and vertex without visible lines (vs deep testaceous and vertex with three longitudinal dark lines in C. lata ), and tegmina only reaching to the posterior margin of the third abdominal segment (vs reaching over the sixth abdominal tergite in C. lata ).

Description.

Measurements (mm). Overall length: male 20.7-21.0, female 28.9-39.5; pronotum length × width: male 6.3-6.5 × 9.3-9.5, female 8.5 × 11.3; tegmen length: male 9.3-9.6 × 5.6-5.9, female 13.0-18.6 × 8.0-11.9.

Male. Colouration testaceous. Surfaces smooth and glossy (Fig. 2A View Figure 2 ). Eyes black. Ocellar spots yellow white. Vertex, frons black; clypeus and labrum yellowish brown (Fig. 2B View Figure 2 ). Pronotum deep testaceous, without spots (Fig. 2E View Figure 2 ). Tegmina auburn, moderately punctured (Fig. 2G View Figure 2 ). Legs ferruginous. Abdomen and cerci dark brown (Fig. 2B View Figure 2 ).

Vertex concealed. Interocular space same as the width between the antennal sockets, slightly greater than ocellar distance. Pronotum nearly semicircular, anterior margin parabolic, posterior margin obtusely angled (Fig. 2E View Figure 2 ). Tegmina reduced, reaching up the 4th abdominal tergite only; apex rounded; venation distinct, all main veins (Sc, R, and CuP) present, Sc thickened (easily visible on ventral side of tegmen) (Fig. 2A, G View Figure 2 ). Wings vestigial, only reaching to the posterior margin of the 3rd abdominal segment, completely covered by tegmina. Front femur Type B2 (Fig. 2F View Figure 2 ). Hind metatarsus depressed-cylindrical, nearly equal to the succeeding segments combined, with single complete row of spines along ventral margin and several additional spines on inner side; four proximal tarsomeres with pulvilli terminal, the one on the second tarsomere occupying practically the whole length of the segment; claws symmetrical and simple; arolium present (Fig. 5A View Figure 5 ). Abdominal tergites unspecialized; knobs along the posterior margin indistinct; weak spiracle-bearing outgrowths of tergite VIII with distinct spiracle. Supra-anal plate with the posterior margin widely rounded and a weak mesal incision. Cerci distinctly segmented, densely covered with bristles. Paraprocts of blaberid type, asymmetrical (Fig. 2H View Figure 2 ). Subgenital plate rounded, slightly asymmetrical; the base of the inner plate bifurcated. Styli cylindrical, apically rounded (Fig. 2I View Figure 2 ).

Male genitalia. Right phallomere with caudal part of sclerite R 1 T rectangular in shape; cranial part of R 1 T more or less straight; R 2 curved; R 3 long; R 4 irregular plate-like; R 5 large, fused with sclerite R 3 in caudal part (Fig. 2J View Figure 2 ). "chaetae-bearing membranous area" absent. Sclerite L2D not divided into basal and apical parts, slender and rod-like, with basal end tapering and a bifurcated outgrowth born near the basal end (Fig. 2K View Figure 2 ). Sclerite L3 hooked, apex slightly rounded, with a small tooth on the inner margin less distinct; folded structure present, with bristles. Sclerite L4U distinct (Fig. 2L View Figure 2 ).

Female. Similar to the male but body somewhat larger.

Etymology.

Derived from the Latin word epunctatus, referring to the lack of visible spots on the body.
