Mekonglema xinpingi (Lin & Li, 2008) comb. nov. Figure 1C

Seychellia xinpingi Lin and Li 2008: 650, figs 1-9 (♂♀).

Type material.

Paratypes: 1♂ and 1♀ (IZCAS), China, Yunnan Province, Xishuangbanna Autonomous Prefecture, Mengla County, Menglun Town, rainforest, leaf litter, 21.9001N, 101.1833E, V-VII.2005, G. Zheng leg. Examined.

Other material examined.

3♀ (including one molecular voucher, IZCAS), same data as paratypes.

Diagnosis.

Mekonglema xinpingi comb. nov. resembles M. bailang sp. nov. but can be distinguished by the following characters: eyes are present (vs. absent); carapace with distinct radial striae (vs. no pattern); bulb is droplet-shaped (cf. Lin and Li 2008: fig. 2) (vs. nearly ellipsoidal).

Description.

See Lin and Li (2008).

Distribution.

China (Yunnan, Xishuangbanna, site 5 in Fig. 33 ), known only from the type locality.

Comments.

This species is transferred to Mekonglema gen. nov. because it shares a similar shape of the copulatory organs with M. bailang sp. nov., the type species of the genus. This placement is also supported by molecular phylogenetic analyses (Fig. 34 ).
