Diagnosis
The salient features of the new species include the following: forewings ( Fig. 3A View Fig ) uniformly yellowish brown; lateral margins of basal part of frons ( Figs 3E View Fig , 4B View Fig ) without short yellowish white transverse markings; ventral margin of aedeagus ( Fig. 4F View Fig ) without small process medially.
Etymology
The specific epithet is derived from the Latin word ‘obscuru ’, referring to the dark brown body.

Aedeagus ( Fig. 4F View Fig ) with phyllobase, phallus tubular, long, blunt rounded end, curved ventrally medially, phyllobase slender, arising from base of aedeagus dorsally. Genital styles ( Fig. 4H–I View Fig ) stout, long, attaining ventral margin of anal segment, apex forked, with large verruciform process at apical ¼.
Host plant
Bambusoideae.
Distribution
China (Yunnan).
Remarks
This species is similar to A. hainanensis gen. et sp. nov. but differs by: (1) lateral margins of basal part of frons ( Figs 3E View Fig , 4B View Fig ) without short yellowish white transverse marking (lateral margins of basal part of frons ( Figs 1E View Fig , 2B View Fig ) with short yellowish white transverse markings, median line yellowish white in A. hainanensis gen. et sp. nov.); (2) antennae ( Figs 3E View Fig , 4B View Fig ) uniformly yellowish brown (antennae ( Figs 1E View Fig , 2B View Fig ) with first segment brown dorsally and yellowish brown to pale brown ventrally, second segment pale yellowish brown, middle part dark brown in A. hainanensis gen. et sp. nov.); (3) ventral margin of aedeagus ( Fig. 4F View Fig ) without small process medially (ventral margin of aedeagus ( Fig. 2F View Fig ) with a small process medially in A. hainanensis gen. et sp. nov.).
