Type material.

Holotype ♂ (IZCAS), China: Yunnan, Mengla, XTBG, secondary tropical seasonal forest (21.907°N, 101.208°E; 612 ± 11 m), by searching, 10.VIII.2007, G. Zheng leg. Examined.

Other material examined.

♂ (NHMSU), China: Yunnan, Mengla, Menglun, Baka Village Nature Reserve (21.722°N, 101.384°E; 716 m), by searching, 17.VIII.2011, Y. Lin leg.

Diagnosis.

This species seems close to M. caribbaea (Gertsch, 1960) and M. stathamae (Gertsch, 1960) in the shape of palpal bulbus, the earlobe-shaped paracymbium and the simple distal part of cymbium (cf. Fig. 21D-F , and figs 30-31, 35-36 in Gertsch 1960), but can be distinguished by lacking a posterior abdominal tubercle, having a cymbial tooth and a distal process (CyP), (Fig. 21A, D, F and fig. 10A, B, G in Lin and Li 2008), with abdominal tubercle and lacking cymbial tooth and CyP in M. caribbaea and M. stathamae (figs 24, 27, 30-31, 35-36 in Gertsch, 1960).

Description.

Male. See Fig. 21A-C and Lin and Li (2008): 501.

Palp (Fig. 21D-G ): light-orange, comparatively large; tibia cup-shaped, except for retrolateral region, a row of long setae almost encircling the distal brim (Fig. 21F, G ). Cymbium nearly transparent, the tip specialized as the cymbial conductor; cymbium with a process and a tooth-shaped cymbial tooth; cymbial fold long and slightly sclerotized, bore a row of ordered setae; paracymbium large, with long setae (Fig. 21D ). Embolus threadlike, coiled into 1.5 loops in tegulum. Tegulum nearly transparent. Spermatic ducts can be seen through tegulum (Fig. 21F, G ).

Female. Unknown.

Distribution.

Southwestern China (Yunnan).
