Yao & Li, 2010
(see
Yao & Li 2010: 6
, f. 9A–D, 10A–D, 11A–D, 12A–C) with similar male chelicerae (
Figs 2
C–D) and epigynum (
Fig. 2A
), but can be distinguished by presence of black margins on carapace (
Fig. 2E
), three distal apophyses on procursus (arrows in
Fig. 1C
) and elliptic pore plates (
Fig. 2B
).
Description. Male (
holotype
):
Total length 2.48 (2.55 with clypeus), carapace 0.90 long, 1.03 wide, opisthosoma 1.58 long, 1.03 wide. Leg I: missing, leg II: 17.01 (4.55 + 0.46 + 4.08 + 6.16 + 1.76), leg III: 11.19 (3.25 + 0.39 + 2.60 + 3.72 + 1.23), leg IV: 14.49 (4.25 + 0.40 + 3.45 + 5.22 + 1.17). Habitus as in
Figs 2
E–F. Carapace yellowish, with black margins and narrow, dark median line; sternum black. Legs brownish, but slightly whitish on distal parts of femora and tibiae, with distinct darker rings on subdistal parts of femora and on proximal and subdistal parts of tibiae. Opisthosoma yellowish, with large black spots. Distance PME-PME 0.13, diameter PME 0.12, distance PME-ALE 0.04, AME absent. Ocular area slightly elevated and separated from rest of carapace. Thoracic furrow shallow, but distinct. Clypeus unmodified. Sternum slightly wider than long (0.68/0.55). Chelicerae (
Figs 2
C–D) with pair of small proximo-ectal apophyses, pair of small distal apophyses on ectal surface, pair of strong frontal apophyses (arrows in
Figs 2
C–D) provided with scales each, and pair of long, hooked frontal apophyses (tips close together). Pedipalps as in
Figs 1
A–D; trochanter with small retrolateral apophysis and ventral apophysis; femur with retrolateral apophysis; patella large; procursus simple proximally but complex distally, with three distal apophyses (arrows in
Fig. 1C
); bulb simple, no other projections except for embolus. Legs with short vertical setae on metatarsi and tarsi, without spines and curved setae.
Female
(IZCAS-Ar39652): Similar to male, habitus as in
Figs 2
G–H. Total length 2.76 (2.90 with clypeus), carapace 0.98 long, 1.09 wide, opisthosoma 1.78 long, 1.13 wide. Leg I: 22.94 (5.59 + 0.48 + 5.64 + 8.35 + 2.88); tibia I L/d: 43. Distance PME-PME 0.12, diameter PME 0.15, distance PME-ALE 0.04. Sternum slightly wider than long (0.65/0.63). Epigynum (
Fig. 2A
) brown, with posterior lip medially (arrow in
Fig. 2B
). Vulva (
Fig. 2B
) with slightly curved anterior arch and pair of elliptic pore plates.
