status

sp. nov.

Habrocestoides emeiensis , sp. nov. (Figs. 8-11)

Material: Female holotype, 2♀ paratypes, Mt. Emei , Sichuan, August 1980, leg. Chen Xiao-en. Paratypes: 2♀, Qianling Park , Guizhou, 21 July 1985, leg. Zhu Chuan-dian ; 1 ♀, Mt. Qingchen , Sichuan, 19 August 1978, leg. Zhu Chuan-dian .

Etymology." The specific name is derived from the type locality, Mt. Emei.

Diagnosis: This new species is allied to H. szechwanensis Prószyñski, 1992 (figs. 26-28), but differs from the latter by: (1) accessory gland attached to or on outside of copulatory opening (Fig. 10); (2) fertilisation duct close to posterior plate, almost vertical to distal part of copulatory canal (Fig. 10 cf. Fig. 27); (3) copulatory canal shorter.

Abdomen oval, pattern as in male, ventrally yellow, with greyish black dots. Epigyne (Fig. 5): with medial bellshaped hood and no posterior round structure internally. Vulva (Figs. 6, 7): copulatory canals arranged longitudinally.

Discussion: Both sexes have been collected from the same place by the same collector at the same time (see material); males accord with females in the form of cephalothorax, ratios of eye sizes and arrangement of eyes, and abdominal pattern, so they are almost certainly correctly matched. The male resembles Habrocestoides sinensis , but the female resembles Habrocestum kweilinensis . This suggests that either Habrocestum kweilinensis (only the female was described) should belong in Habrocestoides or these two genera should be synonymised. Prószyúski (1992a) stated that his classification of Habrocestum kweilinensis was provisional, so possibly it is better to transfer Habrocestum kweilinensis to Habrocestoides as Habrocestoides kweilinensis (Prószyñski, 1992), IICW combination.

Distribution: China (Anhui, Hunan).

Female.: TL 4.0-4.5. Holotype: TL 4.3, CL 1.8, CW 1.7, AEW 1.3, PEW 1.3, EFL 0.9, AL 2.5, AW 1.9. Carapace black-brown, with sparse white hairs, margins and. eye field black, fovea and radial furrows distinct; anterior four eyes equidistant, diameter of AME twice that of ALE, ALE equal to PLE, PME at midpoint between ALE and PLE. Sternum oval, with long white hairs, margin dark brown. Clypeus low, with white hairs, height about one-fourth diameter of AME. Chelicerae brown, two promarginal teeth, one retromarginal. Endites and labium brown, light distal ends with dense hairs. Legs light brown, with black annuli. Legs I and II with sparse lateral spines, III and IV with denser ones; three pairs of ventral spines

on tibia I, five ventral spines on tibia II, two pairs of spines on metatarsi I and II. Formula: 4, 3, 1, 2. Measurements: Abdomen oval, dorsum greyish black; three clear pairs of muscle depressions, five light transverse striae on posterior half (Fig. 8). Ventrally greyish yellow, with black dots. Spinnerets light brown. Epigyne: Fig. 9. Vulva (Figs. 10- 11): accessory gland bar-shaped, attached to or on outside of copulatory opening. Fertilisation duct almost vertical to distal part of copulatory canal.

Male: Unknown.
