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

HEAD AND THORAX. Vertex (Fig. 4A) at base broader than medially long about 1: 0.62, slightly narrower at apex than at base about 0.83: 1, lateral carinae subparallel. Frons (Fig. 4B) longer in middle line than wide at widest part about 1.29: 1, widest at middle level of eyes, median carina weak. Antennae (Fig. 4B) with first segment shorter than second segment about 0.53: 1. Pronotum (Fig. 4A) longer than vertex about 1: 0.84.

Pygofer in posterior view (Fig. 4D) with opening slightly wider than long, ventral margin concave U-shaped, with 2 small lobe-shape processes on both sides of medioventral margin, in lateral view (Fig. 4E) ventral margin longer than dorsal margin, posterior margin sinuate. Aedeagus (Fig. 4F) with phyllobase, phallus tubular, long, blunt rounded end, curved ventrally medially, phyllobase slender, arising from base of aedeagus dorsally. Genital styles (Fig. 4H–I) 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, 4B) without short yellowish white transverse marking (lateral margins of basal part of frons (Figs 1E, 2B) with short yellowish white transverse markings, median line yellowish white in A. hainanensis gen. et sp. nov.); (2) antennae (Figs 3E, 4B) uniformly yellowish brown (antennae (Figs 1E, 2B) 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) without small process medially (ventral margin of aedeagus (Fig. 2F) with a small process medially in A. hainanensis gen. et sp. nov.).
