Kavanaugh, PP-1705 (CASENT 9022598, HNU ), 1 ♁. Paratypes : [same data as holotype] (CASENT 9022595, CAS ), 1 ♁, 3 ♀ ; [same data as holotype] (CASENT 9022599, HNU ), 9 ♀ , 6 juvs ; [same data as holotype] (CASENT 9022596, CAS ), 1 ♁, 2 ♀ , 4 juvs ; [same data as holotype] (CASENT 9022594, CAS ), 2 ♀ ; [same data as holotype] (CASENT 9022597, CAS ), 1 ♀ . Etymology . Patronymic in honor of Pierre Paquin in recognition of his contributions to biospeleology. Diagnosis . Male distinguished from other Maymena 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 M. kehen by the wider scape, wider separation of the spermathecae, and by the lateral margin of the scape, which is uniquely notched in M. kehen ( Fig. 50 G-H). While distinctions between the two known Chinese Maymena species are subtle, they do seem to be consistent. Description . 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 ca. 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).
