The male of
Holotype: male, China: Guangxi autonomous region, Mt. Jiuwanshan, Jiuren Station next to Rongjiang River, 950–1150 m,
Forewing length ca. 14.8 mm. General body color brown. Distance between ocelli nearly as wide as diameter of ocellus. Head slightly wider than pronotum, with a small triangular interocellar patch and another black triangular patch on frons (
Process of tergum 7 forming a large subquadrate plateau, mostly covered with dense sensilla basiconica patches but with few sensilla basiconica at margins (
Zwick & Sivec defined the bulb side of the tube as being ventral, however, the sac of the new species forms a loop so that the spines of apical half of the dorsal surface are actually ventrally directed; we herein discuss dorsal or ventral surfaces of the sac as if it were straight, as such in
Unknown.
The specific epithet refers to the mesal position of the bifurcate lobe on the ventral surface of the aedeagal tube.
China (Guangxi).
The new species appears to belong to a well differentiated subgroup of the montivaga species group (
The new species is characterized by the aedeagal tube being short (≤3× width of bulb) and the ventral, bifurcate process being midlength on the tube. Additionally, the apical half of the sac is clothed with heavy spinules on the dorsal surface.
