1. Mitjaevia asymmetrica Cao & Zhang sp. nov.

( Figs 1 View FIGURE 1 , 15a View FIGURE 15 )

Description: Ground color orange-brown, with black patches, apical 1/3 of anteclypeus black. Scutellum with black vertical line broader at lower part and tapering towards upper part ( Fig. 15a View FIGURE 15 ).

Abdominal apodemes reached posterior of 3 rd sternite ( Fig. 1j View FIGURE 1 ).

Pygofer side with dorsal and ventral margin membranous; dorsal appendage with apex tapering, ventral margin protruded near middle part; without ventral appendage ( Figs 1a, b View FIGURE 1 ). Subgenital plate forming tapering extension apically; lateral margin with a row of enlarged stout setae from subbase to middle part; with 3 macrosetae in middle area ( Fig. 1d View FIGURE 1 ). Style with apex short, foot-like ( Fig. 1e View FIGURE 1 ). Aedeagal shaft moderately long, basal part with three short stick-like processes, two of which extend from ventral side, the third one extending from dorsal side and directed left in caudal view; preatrium as long as shaft; gonopore subapical on ventral surface ( Figs 1g –i View FIGURE 1 ).

Material examined: Holotype: ♂, China: Yunnan Prov., Yingjiang, Mangxian , 24°28'33''N, 97°45'02''E, 1089m, 30 iv 2012, coll. Cao Yanghui ( NWAFU). GoogleMaps

Diagnosis: This new species is mostly similar to M. solitaria Luo, Wang & Song, 2022 in the shape of the subgenital plate and the aedeagus, but differs in having a longer pygofer side and asymmetic aedeagus with three processes.

Etymology: The specific epithet is derived from the Latin word “ asymmetricus ”, referring to the single dorsal process of the aedeagal shaft.
