Nishikawa , 30–31 Dec.1980 .. Differential diagnosis. – M . matsudai is the only species in Luzon, Mindanao and the Visayas with a slender apical part of the phallus and several well-sclerotized rod-like structures in the internal sac (Figs. 11–12). The closely related M. dohertyi from Palawan has a similar phallus in general apearance but with longer, parallel-sided apical part. These species differ also in coloration: M. dohertyi is darker, orange yellow and M. bakeri pale yellow and resembles syntopically occurring net-winged beetles. The species from Borneo and Sumatra having similar male genitalia differ substantially in their coloration and body shape. Description. – Body medium-sized. Head, pro- and mesothorax light brown; metathorax brown, pronotum and elytra bright yellow; antennae brown; trochanters and bases of femora brown, gradually darker apically. Head small, hypognathous, including eyes wider or of similar width as frontal margin of pronotum. Eyes hemispherically prominent, eye diameter 1.2 times frontal interocular distance. Antennae robust, flabellate, lamellae of median antennomeres about 2.3 times longer than body of antennomere. Head and antennae with dense, short, recumbent pubescence. Pronotum flat, 1.35 times wider than long at midline, widest at basal third; covered with dense pubescence, posterior margin slightly bisinuate. Elytra almost parallel-sided, slightly widened posteriorly, widest at apical third; 4.56 times longer than width at humeri; with sparse pubescence. Legs lightly compressed, with dense pubescence. Male genitalia with oval-shaped, slender phallobase, phallus slender apically, with slender, rod-like, sclerotized internal sac (Figs. 11–12). Measurements. – BL 9.25 mm , PL 1.20 mm , PW 1.62 mm , HW 1.70 mm , Edist 0.55 mm , Ediam 0.66 mm . Distribution. – Philippines : Mindanao. Etymology. – The specific epithet is a patronym in honour of Kiyoshi Matsuda, Takarazuka, Japan , who provided material for this study.
