6B11583913514F73AEB0FF57FF3084F8.taxon	diagnosis	Diagnosis. Paecilaemella andi can be distinguished from all its congeners by having two additional transversal continuous stripes separating the chevron and the two parallel longitudinal stripes in the gemini mask (Figs. 1 A, 2 A) (P. armasi bears fragmented spots that may be interpreted as homologous to these stripes). Differs from P. armasi by having a complete gemini mask without fragments, a ventral row of tubercles in the distal prolateral region of the femur IV (Fig. 2 D – E) and by having lateroventral regions of the ventral plate covered with microsetae type 4 (Fig. 3 E – F). Penis with MS D 2 small but accuminate (Fig. 3 A – B). The trochanter of leg IV has a smaller proximal tubercle in the dorsal region than P. armasi and P. geminorum.	en	Medrano, Miguel, Caramori, Laura R., Kury, Adriano B.

This species differs from its congeners by having a fragmented gemini mask (Fig. 1 B, 4 A) and from P. andi and P. geminorum by having 13 tarsomeres of leg IV while the other two species have 12. Furthermore, it has an almost glabrous ventral plate (Fig. 5 B, D) (instead of having microsetae type 4 as in P. andi and P. geminorum). It shares similarities with P. andi by having two transversal spots between the chevron and the parallel lines (Fig. 1 B, 4 A), although in P. andi it forms a non-fragmented line.	en	Medrano, Miguel, Caramori, Laura R., Kury, Adriano B.

6B115839135B4F7DAEB0FC36FF3084F8.taxon	diagnosis	Diagnosis. P. geminorum can be distinguished from other species within the genus by its simple chevron (Fig. 1 C, 6 A) and the absence of distal armature on the prolateral side of femur IV (Fig. 6 D – E). It shares similarities with P. andi, including a continuous gemini mask (Fig. 1 C, 6 A) and a penis with MS D 2 positioned more basally than MS A (Fig. 7 A, D). In contrast, it differs from P. armasi because the latter bears a discontinuous gemini mask (Fig. 1 B, 4 A) and has both MS A and MS D 2 aligned at the same height (Fig. 5 A, C).	en	Medrano, Miguel, Caramori, Laura R., Kury, Adriano B.

6B115839135B4F7DAEB0FC36FF3084F8.taxon	description	Description. (Male holotype) (Fig. 6). Measurements. Body length: 6.8. Maximum width of scutum: 5.6. Carapace length: 2.7, width 3.8. Interocular distance: 1.0. Legs: I: 33.21 (1.07, 9.75, 1.56, 5.87, 9.28, 5.68), II: 66.54 (1.03, 18.03, 2.61, 15.18, 20.05, 9.64), III: 33.89 (1.05, 11.20, 1.67, 6.08, 9.09, 4.80), IV: 51.27 (0.95, 17.32, 2.82, 9.86, 14.02, 6.30). Dorsum. Large sized cosmetid (dorsal scutum length approximately 7 mm). Dorsal scutum in dorsal view epsilon-shaped with shallow cheliceral sockets (Fig. 6 A). Dorsal scutum flat in lateral view (Figs 1 D, 6 B), coxa IV entirely visible in dorsal view (Fig. 6 A), thicker than scutum in lateral view (Fig. 1 D). Ocularium low, narrow, with median depression. Scutal grooves poorly delimited. Scutum entirely unarmed and without any granules (Figs 1 C – D). Free tergites I – III and anal operculum smooth and unarmed (Fig. 6 A). Venter. Coxae I – III triangular, transverse to main body axis. Coxae II to IV connected by tubercle bridges. Ventral elements of coxa I: e 1 = ca. 8 tubercles forming a row; e 2 = 3 large tubercles clustered; e 3 = 1 very large conical process; e 4 = 1 huge bifid process; e 5 = indistinct cluster of ca. 5 cusps. Coxa IV pentagonal, greatly developed, oriented obliquely, but almost parallel to the body axis. Stigmatic area T-shaped with stigmata large, unconcealed. Free sternites smooth and unarmed. Chelicera (Figs 6 A, G). Neither basichelicerite nor hand thickened or swollen in males. Bulla short, rounded, bordered with rounded tubercles, eight ectal and 10 posterior. Movable finger with one basal triangular tubercle and a row of smaller rounded tubercles going distally. Fixed finger with a row of rounded tubercles, larger than those of the movable finger. Pedipalpus (Figs 6 H, I). Trochanter with stout antero-dorsal protuberance. Femur strongly compressed, concave on mesal surface, borders armed with long tubercles. Tibia strongly depressed, with a weakly distinct groove on the mesal edge. Shape asymmetrical, with ectal side more pronounced, armed distally with a row of seven short spines. Corresponding mesal side with a widely spaced row of seven short spines, increasing in size distally. Tarsus moderately elongate, with tight irregular ventro-ectal row of short spines, a much sparser ventro-mesal row of short spines and a proximal mesal cluster of short spines. Legs. Elongate and moderately thick (growing thicker from I to IV). Males with basitarsomeres I thickened, first basitarsomere four to five times longer than the following ones. All femora straight. Femur IV with distal comb of retro-ventral spines. Tibia with two ventral rows of granules. Tarsal claws unpectinate. Tarsal formula: 6 (3) - 6 (3) /? - 18 (3) / 11 - 11 / 12 - 12. Color (1 C – E, 6 A). Pattern color of the gemini mask as follows: Two continuous longitudinal parallel lines forming a suspender on DS, completed by two horizontal lines (chevron and omega stripe) forming the gemini sign. Background of body (dorsal and ventral) and appendages Reddish Black (24), dorsal scutum with lighter mottling Deep Yellowish Brown (75) in carapace, laterals and anterior portion of the abdomen as depicted in Figure 6 A. Pedipalps and chelicerae Dark Grayish Red (20) with lighter mottling Deep Yellowish Brown (75). Blots Yellowish White (92). Distal portion of femur, tibia and patella of the legs Deep Orange Yellow (69). Patella and metatarsus Deep Orange Yellow (69) in the proximal portion. Variation. Some males have reduced tubercles in the distal comb in femur IV. Females with basitarsomeres not thickened in leg I and not as long as those in males, chelicerae slightly smaller than in male. The chevron may exhibit a median division or be divided into more portions, while the omega stripe, whether entire or medianly divided. Genitalia (Fig. 7). Ventral plate of penis rectangular, widening slightly distally. Lateral margins of the dorsal portion of VP (at MS C level) concave along their length, basal to MS C 1 - C 2. Five pairs of larger macrosetae inserted on lateral margin of VP: Two pairs C 1 - C 2 greatly developed, curved and flattened, the third pair of macrosetae, adjacent to C 1 - C 2, robust, cylindrical and straight, is best interpreted as D 1, while D 2 is much reduced and located basally, inserted in the dorsal part of the VP. The fifth pair of MS, here interpreted as A 1, is straight and similar in shape to D 1. A pair of small macrosetae B is located ventro-basally on VP, while E 1 – E 2 also reduced are located ventrally. Microsetae type 4 covering the lateral margins of the VP, but absent in the middle. Stylus strongly curved, cylindrical, with small wattle and a well-developed ventral peak formed by barbels. Dorsal process of glans thumb-shaped.	en	Medrano, Miguel, Caramori, Laura R., Kury, Adriano B. (2025): Three new species of Paecilaemella (Cosmetidae: Flirteinae) from the upper Amazonian Basin.
