Metanoeus luzonensis , new species

(Figs. 15–16)

Material examined. – Holotype. Male ( KMTC), Philippines, Luzon, Bicol National Park , coll. H. Arimoto, 5–8 Feb.1985.

Figs. 13–16. Male genitalia: 13–14: Metanoeus bakeri Kleine, 1926 , 15–16: M. luzonensis , new species. Scale 1 mm. Paratypes. – 5 males ( KMTC), same locality data as holotype ; 1 male ( KMTC), Philippines, Mindanao, coll. N. Nishikawa 12–15 Apr.1983 .

Differential diagnosis. – Both, M. bakeri and M. luzonensis are characterized by the short, very robust phallus but they differ by the length and position of the apical processes (Figs 13–16). In addition, they may be distinguished by the relative size of eyes which are slightly larger in M. bakeri .

Description. – Body medium-sized. Pro- and mesothorax light brown, metathorax brown; head light 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 about as wide as frontal margin of pronotum. Eyes hemispherically prominent, frontal interocular distance 1.09 times eye diameter. Antennae flabellate, lamellae of median antennomeres 1.7 times longer than body of antennomere. Head and antennae with dense, short, recumbent pubescence. Pronotum flat, 1.05 times wider than long at midline, widest at basal third; with dense pubescence. Posterior margin of pronotum slightly bisinuate. Elytra almost parallel-sided, widest at apical third; 4.44 times longer than width at humeri; with sparse pubescence. Legs compressed. Male genitalia very robust with several sclerotized processes (Figs. 15–16).

Measurements. – BL 8.5 mm, PL 1.36 mm, PW 1.44 mm, HW 1.60 mm, Edist 0.52 mm, Ediam 0.47 mm.

Distribution. – Philippines: Luzon, Mindanao.

Etymology. – The specific epithet refers to Luzon island, the type locality of the species.
