Hongkongia songi sp. nov.

Figs. 8–16

Type material: Holotype 3, Kenting National Park, Pingtung County [N 22.6°, E 120.5°], Taiwan, March 12, 2000, Y. L. Xie leg. (THU–Ar–01–0198, 3E6). Paratype, 1Ƥ, same data as holotype (THU–Ar–01–0202, 3EF).

Etymology: The specific name is a patronymic in honor of the late Prof. Daxiang Song who made great contributions to the study of Chinese spiders.

Diagnosis: The new species is very similar to H. reptrix Deeleman-Reinhold, 2001 in the shape of genital organs, but can be distinguished by: (1) the tip of embolus extending into the conductor, while in the latter with the singular S-shaped tip, free; (2) the broader tip of tibial apophysis; (3) the slightly M-shaped anterior hood of epigyne; (4) the shape of spermathecae and copulatory ducts.

Description: Male (holotype). Carapace 1.53 long, 1.22 wide. Abdomen missing. Carapace pale brownish yellow, head about half the width of thorax. Eye (Fig. 9) diameters, AME 0.11, ALE 0.09, PME 0.12, PLE 0.10; eye distances, AME–AME 0.05, AME–ALE 0.01, PME–PME 0.07, PME–PLE 0.03, ALE–PLE 0.03; MOA 0.29 long, front width 0.28, back width 0.26. Clypeus height 0.10. Chelicerae shape as in Fig. 10, with three promarginal teeth and one small retromarginal tooth. Endites, labium and sternum as illustrated as Fig. 11.

Male palp (Figs 14–16): tibial apophysis broad and large, with widening tip and one dorsal spine (only seen from dorsal view); tegulum prolaterally as a semicircular, strongly sclerotized piece; embolus ribbonshaped, long and curved, tip extended into the conductor; conductor long, with broad base, and near the apex with a spinous apophysis.

Female: total body length 4.72: cephalothorax 1.79 long (Fig. 8), 1.36 wide; abdomen 2.93 long, 1.62 wide. Eye diameters, AME 0.12, ALE 0.10, PME 0.11, PLE 0.10; eye distances, AME–AME 0.04, AME–ALE 0.01, PME–PME 0.06, PME–PLE 0.03, ALE–PLE 0.02. MOA 0.31 long, front width 0.29, back width 0.27. Leg formula: 4123.

Abdomen (Fig. 8) cylindrical, covered with short appressed hairs, anteriorly with a cluster of long and erect hairs, central part with two pairs of muscle impressions. Anterior spinnerets long, about 1/4 length of abdomen or longer, widening distally.

Epigynum as illustrated (Figs 12–13): anterior hood slightly M-shaped, the very small copulatory openings centrally; vulva with heavily sclerotized ducts, and spermathecae thin-walled, almost oval; fertilization ducts short, arising from the inner margin of the spermathecae.

Distribution: Known from the type locality only.
