Type species

Augilina longipes Melichar, 1914 .

Diagnosis

Vertex long and narrow, strongly produced anteriorly, posterior margin angularly concave, disc depressed. Frons long and narrow, with median and sublateral carinae, widest at level of second segment of antennae. Ocelli present. Pronotum with anterior margin strongly convex, posterior margin broadly concave; lateral carinae converging apically. Mesonotum large, almost 3 times as long as pronotum, Disc flatteneD. Forewing long, narrow, transparent. HinDwing transparent, longer than half length of forewing. Legs relatively long, hind tibia with single lateral spine medially and with 6 apical spines. First and second metatarsomeres with no spines. Abdomen exceptionally elongate and narrow, sternites chevron-shaped. Male genitalia: anal tube short, enlarged apically. Pygofer in lateral view with dorsal half much narrower than ventral half, hinD margin of pygofer concaveD at upper ⅔, lower ⅓ almost straight; in posterior view, ventral margin with two rounded medioventral processes. Genital styles massive, each with 3–4 processes. Aedeagus of simple structure, with enlarged basement and narrow tubular-shaped apical part. Gonopore subapical.

Distribution

Philippines (Luzon), southern Vietnam, southern China.

Remark

Compared with Melichar’s (1914) description, we propose more concise generic characteristics based on the comparison of four species, and add the generic characteristics of the male genitalia.
