Type material.

Holotype ♂ (IZCAS-Ar42932), China: Yunnan: Xishuangbanna, Mengla County, Xiaolongha Village, Xishuangbanna Biodiversity Conservation Corridor, ravine rainforest (21°24.25'N, 101°36.32'E, 760 ± 20 m alt.), 16.xi.2013, Q. Zhao and Z. Chen leg. Paratypes 1♂1♀ (IZCAS-Ar42933-42934), same data as holotype.

Etymology.

The specific name is a patronym in honor of Dmitri V. Logunov, who contributed significantly to the taxonomy of the genus Eupoa ; noun (name) in genitive case.

Diagnosis.

Eupoa logunovi sp. nov. can be easily distinguished from other congeners by the long, twisted retrolateral femoral apophysis (longer than the tibia), which is absent or shorter than the tibia in others (see Metzner 2022). The female of this species resembles that of E. prima Żabka, 1985 from Vietnam in having very long copulatory ducts, but it can be easily distinguished by the presence of a concave septum (Fig. 9A ) versus absent in E. prima ( Żabka 1985: figs 167, 168), and by copulatory ducts that are connected to the baso-inner portions of spermathecae (Fig. 9B ), whereas in E. prima they are lateral to the spermathecae ( Żabka 1985: fig. 169).

Description.

Male (Figs 8 , 9C, E-H ). Total length 2.02. Carapace 1.02 long, 0.91 wide. Abdomen 0.96 long, 0.74 wide. Clypeus 0.07 high. Eye sizes and inter-distances: AME 0.29, ALE 0.21, PLE 0.13, AERW 0.94, PERW 0.85, EFL 0.53. Legs: I 1.89 (0.60, 0.68, 0.38, 0.23), II 1.61 (0.53, 0.55, 0.30, 0.23), III 1.61 (0.50, 0.50, 0.38, 0.23), IV 2.28 (0.75, 0.80, 0.48, 0.25). Carapace yellow to dark brown, steeply sloped at posterior margin, with an inverted subtriangular yellow area extending from middle of eye field to posterior margin, bearing sparse setae at eye base. Fovea indistinct. Chelicerae pale to yellow, with two promarginal and four retromarginal teeth. Endites colored as chelicerae. Labium slightly darker than endites. Sternum almost heart-shaped, paler medially, covered with thin, brown setae. Legs yellow, with three pairs of ventral spines on metatarsi and tibiae I, respectively. Abdomen suboval, dorsum dark, somewhat mingled with blue, with longitudinal, central, narrow yellow stripe across nearly the entire surface; venter pale, setose, without markings.

Palp (Fig. 8A-D ): femur about 2.5 times longer than wide in retrolateral view, with tapered, S-shaped retrolateral apophysis twisted into pointed tip; patella slightly wider than femur, with spiraled retrolateral apophysis; tibia wider than long, with strongly sclerotized, tapered ventral apophysis extending posteriorly to blunt end and squarish retrolateral apophysis; cymbium setose; bulb swollen, oval; median apophysis transversely extending in ventral view, forming small hook distally; terminal apophysis lamellar, extending antero-retrolaterally, with blunt tip; embolus filiform, coiled into circle distally, tip extending beyond cymbial tip.

Female. (Fig. 9A, B, D ). Total length 2.20. Carapace 0.95 long, 0.82 wide. Abdomen 1.18 long, 0.94 wide. Clypeus 0.08 high. Eye sizes and inter-distances: AME 0.27, ALE 0.19, PLE 0.13, AERW 0.86, PERW 0.79, EFL 0.52. Legs: I 1.94 (0.60, 0.73, 0.38, 0.23), II 1.59 (0.48, 0.58, 0.30, 0.23), III 1.61 (0.50, 0.50, 0.38, 0.23), IV 2.46 (0.78, 0.90, 0.53, 0.25). Habitus similar to that of male except paler, with four distinct yellow bands on dorsum of abdomen.

Epigyne (Fig. 9A, B ): wider than long; atrium large, suboval separated by concave septum, with pair of arched anterolateral ridges and U-shaped posterior ridge; copulatory openings anteriorly located; copulatory ducts membranous at origin, and then leading to lateral, twisted, sclerotized portions that descend obliquely and connect to the base of elongated spermathecae; fertilization ducts triangular, originating from anterior portion of spermathecae.

Distribution.

Known only from the type locality in Yunnan, China.
