Genus
Lysania
Thorell, 1890
Type
species.
Lysania pygmaea
Thorell, 1890
.
Diagnosis.
Lysania
appears closely related to
Zoica
(Lehtinen & Hippa 1979; Hippa & Lehtinen 1983), as both genera share the distal origin of the embolus in the male pedipalp and the absence of a median apophysis (Framenau
et al.
2009). However, the genus differs by the beak-like lateral apophysis, wider conductor and longer copulatory ducts. Additionally, males of
Lysania
have an abdominal scutum dorsally or a sclerotised dorsum, with a metallic luster. Spiders live in small sheet-webs, which are apparently absent in
Zoica
.
Distribution.
Malaysia
(Thorell 1890; Lehtinen & Hippa 1979), Borneo (Lehtinen & Hippa 1979) and
China
(this study).
Remark.
Our examination on two Chinese
Lysania
species confirmed 6 (occasionally 5 or 7) cheliceral retromarginal teeth present. This is unique character among
Lycosidae
and might be diagnostic. More
Lysania
specimens from other countries should be checked.

(SWUC).
Etymology.
The specific name comes from the word “De'ang”, the name of one of the Chinese ethnic minorities that live adjacent to the area inhabited by the new species; noun in apposition.
Diagnosis.
Lysania deangia
is similar to
L. pygmaea
(
Figs 3
A
–
D, 4E
–
H), but differs by the broad and strong lateral apophysis, inflated at the base, shorter embolus (
Figs 1
A
–
B, 2G
–
H) and straight stalk of spermatheca (

–
