Type material.

Holotype ♂ ( SP–GLGS–11– 41), from CHINA: Yunnan Province, Fugong County, Maji Town, native forest (27°28'N, 98°51'E, 1700 m), 10.III.2011, Z.X. Li leg. (hand collecting), deposited in SWUC. Paratype: 1♀ ( SP–GLGS–11– 42), same data as holotype; 1♂ ( SP–GLGS–11– 23), 1♀ ( SP–GLGS–11– 24), from CHINA: Yunnan Province, Baoshan City, Tengchong County, Jietou Town, native forest (25°18'N, 98°21'E, 1850 m), 25.II.2011, L.Y. Wang leg. (hand collecting), deposited in SWUC.

Etymology.

The specific name is derived from the Latin word 'lacrimosus, -a, - um’, meaning ‘lachrymal’, referring to the tear-drop shape of the epigynal median field; adjective.

Diagnosis.

Males of Pseudopoda lacrimosa sp. n. resemble those of Pseudopoda everesta Jäger, 2001 by the embolus with almost equal length of tip and projection, but can be distinguished by the following combination of characters: tip of embolus thin and long (Figs 37, 44); embolic projection large, strip-like (Figs 36-37, 43-44); tip of embolus and embolic projection pointed (Figs 37-38, 44-45); retrolateral tibial apophysis with a small tooth on anterior margin of ventral branch (Figs 37-38, 44-45). Females resemble those of Pseudopoda diversipunctata group by: anterior edges of lateral lobes oval and constrict; internal borders of lateral lobes not touching each other, but can be distinguished from other species of thisgroup by: median field of epigyne narrow, almost tear-drop-shaped (Figs 41, 46); lateral lobes almost as an oblique rectangle, anterior margins of lateral lobes distinctly curved, bracket shaped and pointing medially (Figs 42, 47).

Comments.

Females of Pseudopoda lacrimosa sp. n. could be included in the Pseudopoda diversipunctata -group ( Jäger, 2001). Females of this group are characterized by: lateral lobes of epigyne touching each other only at posterior part, the first winding of internal duct system running from laterally to the median line and the loop situated ventrally ( Jäger 2001). On the other hand, males of Pseudopoda lacrimosa sp. n. have long embolic projection and tip, which could place them in the Pseudopoda latembola -group ( Jäger, 2001).
