(Figs. 13–14)

Metanoeus bakeri Kleine, 1926: 99 .

Material examined. – Holotype. Male ( MZIW), Kolambugan, Mindanao, Baker. ex. coll. R. Kleine, Mus. Zool. Polonicum Warszawa 12/45 , Holotypus nr. 654.

Others. – Male ( KMTC), Philippines, Luzon , Bicol National Park, Nr. Daet, coll. T. Ito, 10 Aug.1988 .

Differential diagnosis. – M. bakeri and M. luzonensis are defined by the short, very robust phallus (Figs. 13–16). That of M. bakeri has shorter apical processes than M. luzonensis . The detailed study of male genitalia is necessary for a reliable differentiation of these species.

Description. – Body medium-sized. Head, pro- and mesothorax light brown, metathorax brown, pronotum and elytra bright yellow; antennae brown; trochanters and bases of femora light brown, gradually changing to dark brown or black apically. Head small, hypognathous, including eyes wider or of similar width as frontal margin of pronotum. Eyes hemispherically prominent, eye diameter 1.04 times frontal interocular distance. Antennae flabellate, lamellae of medial antennomeres about 2.7 times longer than body of antennomere. Head and appendages with dense, short, recumbent pubescence. Pronotum flat, 1.26 times wider than long at midline, widest at lateral third; with dense pubescence. Elytra almost parallel-sided, slightly widened posteriorly, widest at apical third; 3.68 times longer than width at humeri; covered with sparse pubescence. Male genitalia short, robust, phallus with apical processes (Figs. 13–14).

Measurements. – BL 6.75 mm, PL 1.06 mm, PW 1.34 mm, HW 1.52 mm, Edist 0.62 mm, Ediam 0.64 mm.

Distribution. – Philippines: Luzon.
