Diagnostic Features.
Cicynethus hongfuchui
Barrion, Barrion-Dupo & Heong
new species
closely resembles the appearance of
C. floriumfontis
Jocque
1991
from Cape Province,
South Africa
but easily distinguished from the latter in the (
1
) uniformly yellow legs without dark stripes, (
2
) abdomen with a dorsal median and dark brown bands, (
3
) simple epigynum, (
4
) AME> ALE, (
5
) scopulae on ventral tip of tibiae I-IV and entire venter of tarsi I-IV, (
6
) four pairs of short ventral spines on metatarsus I, three pairs on metatarsi II and two pairs each on metatarsi III and IV, (
7
) metatarsus IV as long as metatarsus I, and (
8
) the relatively large posterior spinnerets.
Etymology.
Patronym, in honor of Prof. Chu Hongfu in recognition of his outstanding works on the systematics of Chinese
