description: <i>Maymena paquini</i> Miller, Griswold &amp; Yin, sp. n. urn:lsid:zoobank.org:act: BD950E49-6462-434C-8BDD-587EAE361BB3 Figs 50 D-F, 53-57, 99 <b>Material Examined.</b> Holotype: CHINA: Yunnan: Lushui Co., Daxingdi, Wayala Ku (cave), km 128 rd S-228, 26.13198°N, 98.86149°E, 910 m, 3 August 2005, cave, hu- man impacted and flooded, P. Paquin, D. Kavanaugh, PP-1705 (CASENT 9022598, HNU), 1 ♁. Paratypes: [same data as holotype] (CASENT 9022595, CAS), 1 ♁, 3 &amp;female;; [same data as holotype] (CASENT 9022599, HNU), 9 &amp;female;, 6 juvs; [same data as holotype] (CASENT 9022596, CAS), 1 ♁, 2 &amp;female;, 4 juvs; [same data as holotype] (CASENT 9022594, CAS), 2 &amp;female;; [same data as holotype] (CASENT 9022597, CAS), 1 &amp;female;. <b>Etymology.</b> Patronymic in honor of Pierre Paquin in recognition of his contributions to biospeleology. <b>Diagnosis.</b> Male distinguished from other <i>Maymena</i> for which males are known (i.e., American species) by the elongate palpal tibia (Fig. 54A; compare to Gertsch, 1960: fig. 51). Female distinguished from American species by the shape of the epigynal scape, which is relatively long and narrow (Figs 50 D-F, 56A-C); distinguished from <i>M. kehen</i> by the wider scape, wider separation of the spermathecae, and by the lateral margin of the scape, which is uniquely notched in <i>M. kehen</i> (Fig. 50 G-H). While distinctions between the two known Chinese <i>Maymena</i> species are subtle, they do seem to be consistent. <b>Description.</b> Carapace pale orange. Labrum not swollen, weakly sclerotized, short labral tongue with flat ventral margin (Fig. 56 E-F). Sternum orange. Legs orange. Femoral spots on legs I and II in female, leg I only in male. Tarsal organs set distal to proximal margin of tarsus (ratio of distance from proximal margin of tarsus to tarsal organ over total tarsus length <i>ca.</i> 0.15, Fig. 55F). Abdomen light gray with pair of dorsolateral dark gray patches (Fig. 53). Male palp: Palpal patella and tibia elongate (Fig. 54A); palpal tibia with two trichobothria (Fig. 55D). Cymbium covers ventral part of palpal bulb, dorsal part exposed (Fig. 55 A-B). Hook-like apophysis on prolateral face of cymbium (Fig. 55C). Embolus long and filiform with proximal origin (Fig. 54B). Vulva: Epigynum a scape extending nearly to tracheal spiracle (Fig. 53B, D). Spermathecae round, ducts arise from anteroectal part, run posteriorly; fertilization ducts diverge from copulatory ducts, run anteromesally; copulatory ducts loop near base of scape (Fig. 50F), terminate in paired atria near middle of scape (Fig. 56 A-C). Male (CASENT 9022595): Total length 2.20, carapace 1.06 long, 0.95 wide, clypeus 0.25, sternum 0.56 long, 0.60 wide, coxa IV separated by 0.44 times their width. Leg I: femur d1, p2, r2, patella d2, tibia d1, p3, r1, metatarsus p1; Leg II: femur d1, p1, r2, patella d2, tibia d1, p2-3, r1, metatarsus with all prolateral setae strong; Leg III: femur d1, p1, r1, patella d2, tibia d1, p1, r1, metatarsus p1; Leg IV: femur d1, p1, r1, patella d2, tibia d1, p2, r1. Metatarsal macrosetae kinked proximal to center. Metatarsal trichobothria: TmI: 0.24; TmII: 0.24; TmIII: 0.33. Leg measurements: see Appendix A. Epiandrous gland spigots in four clusters of two-three spigots each (Fig. 56D). Posterior lateral spinnerets with flagelliform and aggregate gland spigots reduced to nubbins (Fig. 57F). Female (CASENT 9022595): Total length 2.50 carapace 1.18 long, 0.99 wide, clypeus 0.23, sternum 0.66 long, 0.64 wide, coxa IV separated by 0.59 times their width. Leg I: femur d1, p1-3, r2, patella d2, tibia d1, p3, r1, metatarsus with all prolateral setae strong; Leg II: femur d1, p1, r1-2, patella d2, tibia d1, p2-3, r1, metatarsus with all prolateral setae strong; Leg III: femur d1, p1, r1, patella d2, tibia d1, p2, r1, metatarsus p1; Leg IV: femur d1, r0-1, patella d2, tibia d1, p2, r1. Metatarsal trichobothria: TmI: 0.25; TmII: 0.27; TmIII: 0.34. Leg measurements: see Appendix A. Spinnerets (Fig. 57 A-D).
