Fig. 99 Holotrichia brunneipennis Moser, 1916: 186 ( type loc.: Juranda, India ). Diagnosis External morphology of adult ( Fig. 99 ). Antenna 10-segmented. Dorsal surface glabrous, densely punctate. Clypeus shorter than frons, with conspicuous punctures, oblique laterally, anterior edge strongly emarginate at middle. Frons with punctures similar to those of clypeus; strong frontal carina. Pronotal surface densely punctate (distance between punctures smaller than diameter of puncture); anterior pronotal margin glabrous, regularly flanged; posterior margin glabrous; lateral margins smooth, moderately elevated at anterior half; anterior angles sharp and not projected forward, posterior angles obtuse and rounded. Prosternal process with two-pointed ends. Scutellum densely punctate, glabrous. Elytral surface glabrous and punctate, without striations defined, epipleuron with short pubescence on basal half. Foretibia with strong dorsal carina. Meso- and metatibia with transverse carina interrupted, and inner margin of dorsal surface with sharp spines. Pygidium glabrous, with deep punctures irregularly distributed, apex with short pubescence. Ventrites 1 and 2 densely punctate, with conspicuous decumbent pubescence regularly distributed. Ventrites 3 and 4 with a transversal row of short and robust pubescence arranged at middle of sternites. Ventrite 5 with strong punctures and long pubescence irregularly distributed on posterior half. Ventrite 6 concave moderately bulging anteriorly, punctures unevenly distributed and with long pubescence on posterior margin. Female unknown. Material examined Lectotype (here designated) INDIA • ♂ ; “Juranda; Ind. or” [India]; “ Holotrichia brunneipennis Type Mos”; “ brunneipennis Mos ”; “ BRUNNEIPENNIS Mos ”; “Typus”; “Lectotype Miridiba brunneipennis ( Moser, 1916 ) Chuan-bu Gao and Coca-Abia 2017”; MFNB . Remarks Moser (1916) described Holotrichia brunneipennis from Juranda ( India ). We have studied a male type specimen conserved in MFNB, which shows external features that characterize the genus Miridiba . Hence, we have transferred M. brunneipennis to Miridiba . Unfortunately, we were unable to study the male genitalia because this type specimen only conserves the ninth genital segment, which does not allow us to assign it to any genital morphotype. Therefore, M. brunneipennis is considered as species incertae sedis within the genus Miridiba . The syntype specimen is designated as lectotype . Distribution India .
