Type material.

Holotype: ♀ (NSMT-Ar8351), Vietnam: Phu Quoc Island, Duong Dong, 40 m, 19.III.2009, H. Ono leg., not examined.

Other material examined.

3♂ 1♀ (IZCAS-Ar44427-Ar44430), China, Yunnan: Menglun Town: Xishuangbanna Botanical Garden , 21.910767°N, 101.2709° E, ca 572 m, 1-15.V.2007, rubber-tea plantation, fogging. Guo Zheng leg.

Diagnosis.

The male can be distinguished from Allomicythus suochao sp. nov. by the absence of tegular apophysis and conductor (Fig. 1B, C ) [vs present (Fig. 2B, C )]. The female can be distinguished from A. suochao sp. nov. by the absence of a pair of lateral pockets of epigyne and spermatheca as long as the diameter of the bursa (see Ono 2009: figs 18, 19) [vs lateral pockets present and spermatheca almost twice as long as the diameter of bursa (Fig. 3 )].

Description.

Male (IZCAS-Ar44427) (Fig. 4A ). Total length 3.40; carapace 1.04 long, 1.22 wide, opisthosoma 1.86 long, 1.03 wide. Eye sizes and interdistances: AME 0.07, ALE 0.07, PME 0.06, PLE 0.06, AME-AME 0.01, AME-ALE 0.01, PME-PME 0.05, PME-PLE 0.02, AME-PME 0.04, ALE-PLE 0.01. Anterior eye row slightly recurved, posterior eye row procurved. Chelicerae with three promarginal teeth. Tarsus and metatarsus in Leg I and II with scopula ventrally. Leg measurements: I 3.15 (0.96, 1.14, 0.60, 0.45), II 3.07 (0.93, 1.10, 0.60, 0.44), III 2.65 (0.72, 0.89, 0.60, 0.44), IV 3.76 (0.96, 1.28, 0.97, 0.55). Opisthosoma oval, with dorsal scutum 1/5 the length of the opisthosoma, venter brown. Spinnerets yellow-brown.

Palp (Fig. 1A-C ). Tibia almost as long as patella. Retrolateral tibial apophysis (RTA) long and straight, almost as long as tibia, terminal slightly curved. Cymbium almost 3 × longer than wide, with retro-proximal cymbial outgrowth (RPO). Subtegulum (ST) almost oval in prolateral view and unobvious in ventral view. Tegulum almost oblong. Tegular apophysis (TA) and conductor (C) absent. Embolus (E) helically twisted, almost coiled two turns.

Female. See Ono (2009).

Distribution.

Vietnam, China (Yunnan).

Notes.

The male is described here for the first time.
