Speocera cattien Li & Li 2019, sp. nov.

Speocera cattien Li & Li sp. nov. (Figs 16–17, 56A)

Material examined. Holotype ♂ (IZCAS), Vietnam, Dong Nai Province, Cat Tien National Park, Natural Forest (11º27.005′N, 107º21.863′E), elev. 173 m, 5.IX.2015, leg. Q. Zhao, Y. Li & Z. Chen. Paratype 1♀ (IZCAS), same data as holotype.

Etymology. The specific name is derived from the type locality; noun.

Diagnosis. The new species is similar to S. xuanson Li & Li sp. nov., but males can be distinguished by the unmodified chelicerae (Fig. 56A), the incrassate palpal tibia and cymbium (Figs 16A–B) and the sickle-shaped embolus (Fig. 16D), and females by the short afferent spermathecae and the large oval spermathecae (Fig. 17A). S. xuanson males have the chelicerae laterally excavated, with a small horn-like apophysis (Figs 57I–J), the palpal tibia and cymbium not incrassate (Figs 51A– B), and a nearly straight embolus (Fig. 51D), and females have very small spermathecae with long, curved afferent spermathecae (Fig. 52A).

Description. Male. Total length 1.01; carapace length 0.46; carapace width 0.43; abdomen length 0.63; abdomen width 0.38. Prosoma: carapace pyriform, narrowing gradually anteriorly; light yellow, suffused with purplish pattern (Fig. 17C); pars cephalica flat; fovea not visible. Sternum light yellow, suffused with purplish color, as long as wide. Endites light yellow, suffused with purplish tinge; with serrula; labium light yellow, suffused with purplish tinge. Clypeus nearly vertical; short. Chelicerae light yellow; promargin with a series of six teeth reaching the lamina; retromargin with two small denticles (Fig. 56A). Eyes: six contiguous eyes surrounded by black pigmentation, ALE, PME nearly subequal, PLE largest (Fig. 17C). Opisthosoma oval; purplish. Legs light yellow; leg formula 4123; leg lengths I 2.20 (0.63, 0.16, 0.64, 0.48, 0.29); II 1.99 (0.58, 0.16, 0.55, 0.42, 0.28); III 1.74 (0.49, 0.14, 0.46, 0.39, 0.27); IV 2.45 (0.67, 0.17, 0.70, 0.54, 0.36). Genitalia (Fig. 16). Palpal femur long; palpal tibia and cymbium incrassate, tibia about 1.2 times as long as cymbium (Figs 16A–B). Cymbium conical, without prolateral extension. Bulb spherical. Embolus long, sickle-shaped, dark and basally with a short associated sclerite; sperm duct initially wide, gradually narrowing distally (Fig. 16D).

Female. Total length 1.10; carapace length 0.51; carapace width 0.44; abdomen length 0.58; abdomen width 0.52. Similar to male in color and general features (Figs 17D–E) but larger. Leg lengths I 2.08 (0.59, 0.18, 0.59, 0.44, 0.28); II 1.81 (0.50, 0.14, 0.51, 0.39, 0.27); III 1.60 (0.45, 0.13, 0.41, 0.37, 0.25); IV 2.18 (0.63, 0.15, 0.60, 0.51, 0.30). Genitalia. Internal genitalia with afferent spermathecae short, curved, not extending past the sides of the abdomen; tip of the afferent spermathecae question mark shaped (Fig. 17B); spermathecae large, oval (Fig. 17A).
