Zorotypus medoensis Hwang

( Figs 6 , 7 )

Zorotypus medoensis Hwang, 1976: 225 .

Material examined. 2 apteron ♂♂, 1 apteron ♀, 2 alate ♀♀, labeled: ‘ China, Xizang A. R. [= Tibet], Motuo Hsien [ffiRθ], Hanmi [R÷], 29°21’50’’N, 95°07’48’’E, under bark covered with moss, 15.vii.2013, 2100 m, Chao Wu leg.’ (pcWC, pcBW); 9 deälate ♀♀, labeled: ‘ China, Xizang A. R., Motuo Hsien, 80K, 29°39’18’’N, 95°29’25’’E, under bark, 2.viii.2013, 2100 m, Wen-Xuan Bi leg.’ (pcBW).

Biology. All individuals were collected under barks of large fallen decomposing logs ( Fig. 7 ).

Distribution. Southwestern China: Xizang Autonomous Region.

Comments. According to Hwang (1976), Zorotypus medoensis is very similar to Z. sinensis in general morphology, and can be separated from the latter only by the chaetotaxy of male sternum VIII, and form of the male genitalia. For comparative purposes, important diagnostic features of Zorotypus medoensis from the type locality are figured ( Fig. 6 ). Both Z. medoensis and Z. sinensis lack a strongly elongate and coiled flagellum, indicating that these two species may be more closely related to Z. ceylonicus Silverstri from Sri Lanka ( Hwang 1974: 427) than to the southeastern Asian and central American species that share this structure (see ‘Comparative diagnosis’ of Z. hainanensis sp. n. above, and Mashimo et al. 2013: 512).
