Diagnosis.
This genus can be distinguished from other lycosid genera by the slender body, several chevronlike yellow white markings on the dorsum of opisthosoma and two-segmented posterior spinnerets with elongated basal segments (
Figs 4
A–B, 6A–B, 8A–B). Male pedipalps have a hook-like, peaked terminal apophysis, membranous conductor, slender embolus and bifid median apophysis, of which the anterior arm is longer than the posterior one (
Figs 3
A–B, 4C–D, 5A–B, 6D–E, 7A–B, 8C–D). Epigyne thickly covered with white setae, strongly extending backwards (
Figs 4
E, 6F, 8E). A strong, posteriorly extended scape (
Figs 3
C–D, 4E–G, 5C–D, 6F–G) or an obvious epigynal atrium (
Figs 7
C, 8E–F) present. Stalk of spermathecae relatively slender and slightly curved and head of spermathecae ball-like (
Figs 3
D, 4G, 5D, 6G, 7D, 8G). Additionally,
Hippasa
species spin funnel-like webs, although juvenile webs are more sheet-like (pers. obs.).
Distribution.
Africa and Asia.
Composition and species groups division.
In total, there are 37 described species. The Japanese species,
H. babai
Tanikawa, 2007
is synonymised with the newly revalidated
H. lingxianensis
Yin & Wang,
1980
in this paper. Based on the characters of male palps and female epigynes, 30 species can be assigned to two species groups: the
Hippasa
greenalliae-
group and the
Hippasa
partita-
group.
