Miridiba laosana (Moser, 1912)

Holotrichia laosana Moser, 1912: 439 (type loc.: Tonkin, Laos).

Holotrichia laosana – Frey 1970: 249 (in key).

Miridiba laosana – Coca-Abia 2008: 680, 683 (combination; type material; in key).

Diagnosis

External morphology of adult (Coca-Abia 2008). Dorsal surface glabrous. Clypeus with anterior edge depressed at middle and elevated. Pronotum with anterior margin strongly flanged; posterior margin finely flanged except at middle; lateral margin weakly serrated with few setae; anterior angles almost right, not projected forward or upward, posterior angles obtuse and strongly rounded. Elytra with shiny appearance, weakly punctate, almost without punctures at apices, elytral apices strongly truncate. Foretibia with carina moderately developed. Meso- and metatibiae with transverse carina interrupted at middle, inner margin of dorsal surface with few small spines. Pygidium glabrous, with pubescence on apical margin. Male genitalia: parameres very similar to those of M. behrensi, with dorsal branch narrowed at apex. Ventral branches with elevations as waves at outer margin, apices expanded. Endophallus with spines thicker and stronger at proximal half. Female genitalia not studied.

Remarks

Coca-Abia (2008) studied the species and designated lectotype and paralectotype (MFNB) (these types were lost on the way back to MFNB). This species shows features of external morphology and genitalia that characterize the morphotype IV “ Bidentata ”. Hence, this species is included in this genital morphotype.

Distribution

Laos.
