Agnetina den Cao & Bae, 2006

Agnetina den Cao & Bae, 2006. Entomological Research. 36: 45. Type locality: Pu Mat National Park (Ban Diem), Nghe An Province, Vietnam.

Material examined. 1 male, Vietnam: Guang Nam Province, Phuocson, Phuemy, 559 m, 2012. V. 5, W.H. Li.

Distribution. Central Vietnam (Nghe An, Guang Nam).

Remarks. the species may be recognized by the general dark color pattern and patterned pronotum and legs, abdominal terga 7–8 with submedian patches of sensilla basiconica, and hemitergites with a cluster of long, dense fine setae on their inner sides.

Our specimen agrees well with the descriptions and figures of Cao & Bae (2006), especially with the detailed color pattern and general shape of the terminalia. However, the patches of sensilla basiconica of terga 7–8 and the diagnostic cluster of long fine setae of hemitergites are not as prominent as originally illustrated ( Figs. 5–6 in Cao & Bae 2006).
