Diagnosis

External morphology of adult (Fig. 98). Dorsal surface glabrous and densely punctate. Clypeus with anterior edge widely emarginate at middle and oblique laterally. Frontal carina developed and sharp. Anterior pronotal margin flanged, with a concavity moderately developed at each lateral end; posterior margin glabrous; lateral margins smooth, elevated laterally at anterior third; anterior angle acute; posterior angle obtuse and rounded. Scutellum densely punctate. Elytral surface with punctures more scattered than those on pronotum; epipleuron with long yellow setae along all its length. Foretibia with dorsal carina moderately developed. Meso- and metatibia with transverse carina interrupted at middle; inner margin of metatibial dorsal surface with two strong spines. Pygidium dense punctate and conspicuously pubescent; apex with long pubescence. Ventrites punctate and conspicuously pubescent. Ventrite 2 with short pubescence decumbent. Ventrites 3 and 4 with scattered pubescence at middle. Ventrite 5 with long pubescence on posterior half, irregularly distributed. Ventrite 6 with long pubescence along posterior margin. Male genitalia: parameres (Fig. 23) with dorsal branches of dorsal tubular complex sharp apically and with a tendency to converge (Fig. 23A), apices of ventral branches of dorsal tubular complex convergent (Fig. 23B) and curved ventrally (Fig. 23C); in lateral view, dorsal and ventral branches of dorsal tubular complex forming a semi-circular concavity (Fig. 23C). Ventral branches reduced. Phallobase longer than parameres. Endophallus, temones and female genitalia not studied.

Material examined

Lectotype (here designated) VIETNAM • ♂; “ Annam ” [Centre of Vietnam]; “ Miridiba ciliatipennis (Moser, 1913) CH. Bu Gao det. 2017”; MFNB.

Paralectotype (here indicated) VIETNAM • 1 ♀; same collection data as for the lectotype; MFNB .

Other material

VIETNAM • 1 ♂, 1 ♀; Frey det.; MFNB .

Remarks

Moser (1913b) described Holotrichia ciliatipennis without indicating how many species he studied. Frey (1970) transferred this species to Neodontocnema Arrow, 1948 and illustrated the parameres only in dorsal view.The first author of the present paper has examined four specimens of H. ciliatipennis (MFNB) (3 males and 1 female, including two types), which show external and genital features that characterize Miridiba . However, male genitalia show features not shared with species belonging to other genital morphotypes of Miridiba . Hence, we transfer H. ciliatipennis to Miridiba and describe the male genitalia morphotype IX “ Ciliatipennis ” based on this species. Moreover, we designate lectotype and paralectotype.

Distribution

Vietnam, Thailand.
