COLORATION. Body reddish brown; antenna reddish brown; legs reddish brown; flanges yellowish brown; ribbon-like setae whitish yellow.

Male

Unknown.

Distribution

Vietnam (Northern Vietnam, Central Vietnam) ( Fig. 29 View Fig ).

Host

Oxyartes sp. ( Lonchodidae : Necrosciinae ) based on the foraging behavior of a female.

Remarks

This new species can be easily distinguished from any other species by the dense scale-like setae on the body. A paratype female (Cuc Phuong, 21 August 2019) was collected by FIT at night (9 p. m.). The female attacks the eggs of Oxyartes sp. and buries them in the soil. Details of the foraging behavior are provided in the discussion.
