Diagnosis

External morphology of adult (Fig. 47). Body size 18.9–20.0 mm. Dorsal surface shiny. Clypeus concave, with oblique sides, anterior edge moderately emarginate at middle and pubescence short. Frons with conspicuous pubescence; punctures thicker than those of clypeus; angular strong carina with a midvertex. Pronotum with hardly visible short setae in each puncture; pronotal anterior margin sloped forward, glabrous, at most, some short setae; posterior margin glabrous; lateral margins strongly serrated, with conspicuous short pubescence; anterior angles obtuse, not projected forward; posterior angles obtuse and rounded. Prosternal process tongue-shaped. Scutellum punctate, with short setae. Elytra with punctures regularly distributed, disc with very short setae in each puncture hardly visible; basal and lateral part with conspicuous long pubescence; epipleuron with pubescence except on apex. Foretibia with dorsal strong carina, insertion of inner spur in male equidistant between second and third outer tooth. Meso- and metatibia with complete transverse carina, inner margin of dorsal surface with spines. Prepygidium regularly punctate, with short but conspicuous pubescence. Pygidium irregularly punctate, with conspicuous pubescence, longer on apex; apical margin moderately raised. Ventrite 5 moderately depressed at posterior half, with strong punctures and pubescence, longer on depressed part. Ventrite 6 with punctures irregularly distributed, conspicuous pubescence, bulky at anterior margin, bulge without punctures. Male genitalia: parameres (Fig. 48) with setae on ventral side of dorsal branches and dorsal side of ventral ones; in lateral view, moderately bent towards apices at two stretches; apices of ventral branches thin and slightly curved outwards and upward, with a small apical tip. Endophallus (Fig. 49) with spines at distal end; all proximal part of sac covered with trichodea sensilla. Female genitalia (Fig. 50) as that of morphotype I, with two dark rounded sclerotized areas on dorsal membrane of median oviduct.

Remarks

Nomura (1977) described Miridiba kuraruana based on a male holotype and thirty-three paratypes (18 males and 15 females). After studying the holotype and four paratypes of M. kuraruana, we conclude that M. kuraruana shows features of male and female genitalia that characterize morphotype I “ Trichophora ”. Hence, this species is included in this genital morphotype I.
