Eye sizes and interdistances: AME 0.08, ALE 0.06, PME 0.06, PLE 0.06, AME-AME 0.05, AME-ALE 0.03, PME-PME 0.08, PME-PLE 0.08, AME-PME 0.09, ALE-PLE 0.05. MOA 0.21 long, front width 0.19, back width 0.19. Clypeus height 0.29. Chelicerae with 2 promarginal teeth. Leg measurements: I 3.00 (0.76, 0.24, 0.73, 0.78, 0.49), II 2.34 (0.64, 0.25, 0.48, 0.61, 0.36), III 2.34 (0.64, 0.25, 0.47, 0.64, 0.36), IV 3.23 (0.84, 0.25, 0.73, 0.96, 0.45).
Colouration (Fig.
4
A, B). Carapace red-brown, edge brown. Chelicerae, endites, labium and sternum red-brown. Legs yellow-brown with black ring pattern. Opisthosoma oval, dark brown with numbers of small yellow-brown spots, with ventral scutum covering opisthosoma, dorsal white with purple spots. Spinnerets purple.
Palp (Fig.
2
). Patella almost as long as tibia. Tibia with two apophyses, retrolateral tibial apophysis blunt, triangular-shaped; dorsal tibial apophysis lamellate. Cymbium almost two times longer than wide. Cymbial furrow with a hood anteriorly and a digitiform apophysis posteriorly. Bulb almost 1.5 times longer than wide. Tegulum almost round. Tegular apophysis black, terminal sharp. Conductor bent, originating dorsally on bulb, with slightly widened tip. Embolus slender and whip-like, distal portion pointing to middle of conductor in ventral view. Base of embolus large, with large membranous prolateral part, arising at 7
o'clock
position.
Female (IZCAS-Ar44409). Total length 2.57; carapace 1.22 long, 0.84 wide, opisthosoma 1.35 long, 0.92 wide. Eye sizes and interdistances: AME 0.08, ALE 0.07, PME 0.06, PLE 0.06, AME-AME 0.05, AME-ALE 0.03, PME-PME 0.09, PME-PLE 0.10, AME-PME 0.10, ALE-PLE 0.06. MOA 0.23 long, front width 0.20, back width 0.21. Clypeus height 0.33. Chelicerae with 2 promarginal teeth. Leg measurements: I 2.90 (0.77, 0.27, 0.65, 0.73, 0.48), II 2.44 (0.67, 0.27, 0.49, 0.61, 0.40), III 2.45 (0.66, 0.28, 0.49, 0.66, 0.36), IV 3.34 (0.87, 0.28, 0.75, 0.98, 0.46).
Colouration (Fig.
4
C, D). As in male, except lacking scutum on opisthosoma and opisthosoma with three pairs of white spots, first pair oblong-oval, longitudinal, largest; second pair irregular in shape, positioned lateral to the first pair, third pair ovoid, transverse, slightly connected to the second pair.
Epigyne (Fig.
3
). Epigynal plate as long as wide. Copulatory openings located on anterior portion of epigyne. Copulatory ducts intertwined. Spermathecae kidney-shaped, two times wider than copulatory ducts. Fertilisation ducts directed at the 2 o'clock position from spermathecae.
Diagnosis
The male is similar to that of
Asceua radiosa
Jocque
, 1986 by the triangular-shaped retrolateral tibial apophysis, same shaped cymbial furrow and tegular apophysis needle-shaped. Females share the same shape of the copulatory duct. However, the new species can be distinguished from
A. radiosa
by the cymbial furrow with a digitiform apophysis posteriorly (Fig.
2
C) [vs. absent in
A. radiosa
(see
Jocque
(1986)
, fig. 4)] and tegular apophysis strongly curved (Fig.
2
B) [vs. almost straight in
A. radiosa
(see
Jocque
(1986)
, fig. 5)]. The female can be distinguished from
A. radiosa
by the kidney-shaped spermatheca (Fig.
3
B) [vs. oval in
A. radiosa
(see
Jocque
(1986)
, fig. 8)].
Etymology
The species is named after the collector Mr. Haochong Yang; noun (name) in genitive case.
Distribution
Known only from the type locality (Fig.
9
).
