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.

Description

MEASUREMENTS. Body length including forewing: male 3.65–4.10 mm (N = 4), female: 4.35–4.45 mm (N = 2); forewing length: male 2.85–3.15 mm (N = 4), female 3.30–3.45 mm (N = 2).

COLORATION. General color yellowish brown to dark brown ( Fig. 3A–F View Fig ). Frons dark brown except apical part yellowish white, carinae brown. Clypeus dark brown. Genae pale yellowish white except areas below level of lower margin of eyes dark brown. Eyes reddish brown. Antennae yellowish brown ( Figs 3D–E View Fig , 4B View Fig ). Vertex, pronotum and mesonotum yellowish brown to dark brown ( Fig. 3C View Fig ). Forewing yellowish brown, veins brown ( Figs 3A View Fig , 4C View Fig ). Legs yellowish brown ( Fig. 3F View Fig ). Thorax with ventral part pale yellowish brown, lateral areas with dark brown markings. Abdomen brown to dark brown. Male pygofer and anal segment dark brown.

HEAD AND THORAX. Vertex ( Fig. 4A View Fig ) 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 View Fig ) 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 View Fig ) with first segment shorter than second segment about 0.53: 1. Pronotum ( Fig. 4A View Fig ) longer than vertex about 1: 0.84. Mesonotum ( Fig. 4A View Fig ) longer than pronotum and vertex combined about 1.14: 1. Forewing ( Fig. 4C View Fig ) longer in middle line than wide at widest part about 2.62: 1.

MALE GENITALIA. Anal segment of male ( Fig. 4D View Fig ) short, ring-like. Pygofer in posterior view ( Fig. 4D View Fig ) 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 View Fig ) ventral margin longer than dorsal margin, posterior margin sinuate. 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.).
