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 View Figure 54 ; 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 View Figure 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 View Figure 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 View Figure 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 View Figure 55 ). Abdomen light gray with pair of dorsolateral dark gray patches ( Fig. 53 View Figure 53 ).

Male palp: Palpal patella and tibia elongate ( Fig. 54A View Figure 54 ); palpal tibia with two trichobothria ( Fig. 55D View Figure 55 ). Cymbium covers ventral part of palpal bulb, dorsal part exposed ( Fig. 55 View Figure 55 A-B). Hook-like apophysis on prolateral face of cymbium ( Fig. 55C View Figure 55 ). Embolus long and filiform with proximal origin ( Fig. 54B View Figure 54 ).

Vulva: Epigynum a scape extending nearly to tracheal spiracle ( Fig. 53B, D View Figure 53 ). 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 View Figure 50 ), terminate in paired atria near middle of scape ( Fig. 56 View Figure 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 View Figure 56 ). Posterior lateral spinnerets with flagelliform and aggregate gland spigots reduced to nubbins ( Fig. 57F View Figure 57 ).

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 View Figure 57 A-D).
