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
Jaeger
, 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 (
Jaeger
, 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 (
Jaeger
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 (
Jaeger
, 2001).
