Diagnosis

This species could be easily differentiated from other species of Micropodabrus by its brown elytra and the structures of aedaegus: ventral process of each paramere wide, laterophyses strongly sclerotized and bent dorsally at apices.

Etymology

The specific epithet is derived from the Latin brunneus (brown) and penna (wing), referring to its brown elytra.

Holotype

TAIWAN: Ƌ, Nantou Hsien, Meifeng , alt. 2100 m, 28 Nov. 1995, leg. M. Owada ( NMNS).

Description

Male ( Fig. 12B )

Body length: 6.5 mm; width: 1.5 mm.

BODY. Black and shiny, elytra brown. Body densely covered with recumbent gray pubescence, pronotum and elytra with brown pubescence, which is slightly longer on the latter.

HEAD. Rounded, temples slightly narrowed posteriorly, surface densely and coarsely punctate; eyes moderately protruding, head width across eyes slightly wider than anterior margin of pronotum; terminal maxillary palpomeres subtriangular, widest nearly in middle, acurate on apical parts of inner margins, acute at apices; antennae filiform, slightly thickened, extending to elytral midlength, antennomeres II nearly as long as wide, III about twice as long as II, IV about one-third longer than III, XI slightly longer than X, pointed at apices.

PRONOTUM. Subquadrate, slightly wider than long, slightly widened posteriorly, anterior margin arcuate, lateral margins sinuate, posterior margin narrowly bordered and bisinuate, anterior angles rounded, posterior angles nearly rectangular; disc distinctly convex on posterolateral parts, surface lustrous, sparsely and finely punctate.

ELYTRA. About 3.0 times as long as humeral width, 4.5 times longer than pronotum, nearly parallelsided, disc densely and coarsely punctate.

LEGS. With all tarsal claws bifid.

AEDEAGUS ( Fig. 14 G–I). Ventral process of each paramere wide, slightly sinuate at outer margins, moderately hooked at apex; conjoint dorsal plate of parameres well-developed, slightly shorter than the length of ventral processes and distinctly narrower than distance between outer margins of ventral processes, slightly sinuate in middle of lateral margins, with nearly straight apical margin; laterophyses separated, strongly sclerotized and bent dorsally at apices, situated in middle of dorsal side of median lobe, as long as conjoint dorsal plate.

Female

Unknown.

Distribution

Taiwan.
