Ancylonycha leucophthalma – Burmeister 1855: 316 (combination). Holotrichia leucophthalma – Dalla Torre 1912: 204 (catalogue). Miridiba leucophthalma – Coca-Abia 2008: 681 , 683, fig. 17 (combination; type material; in key). Diagnosis External morphology of adult ( Coca-Abia 2008 ). Dorsal surface glabrous. Clypeus with oblique sides, anterior edge rather emarginate at middle. Frons with strong carina. Pronotal surface densely punctate, glabrous; anterior margin strongly flanged; posterior margin finely flanged except at middle; lateral margins smooth; anterior angles sharp and elevated, not projected forward; posterior angles obtuse and rounded. Epipleuron sparsely pubescent. Meso- and metatibia with transverse carina interrupted at middle, inner margin dorsal surface with very few spines moderately developed. Pygidium with pubescence hardly visible, conspicuous pubescence on apex. Tegmen ( Coca-Abia 2008 : fig. 17): Parameres ( Fig. 8 ) with dorsal branches shorter than ventral ones, wrinkled at distal end. Endophallus with strong spines, larger towards distal end, placed helicoidally surrounding internal walls of sac. Temones reduced, apophysis separated at distal end. Female genitalia not studied. Material examined INDONESIA • 1 ♂ ; Indonesia , Java ; MFNB ( Fig. 8 ) . Remarks Coca-Abia (2008) studied this species and transferred it to Miridiba . Miridiba leucophthalma shows features of external morphology and male genitalia that characterize morphotype III “ Leucophthalma ”. Hence, this species is included in this genital morphotype. Distribution Indonesia ( Jakarta , Java ).
