Metanoeus parallelus , new species

(Figs. 5–7)

Material examined. – Holotype. Male ( LMBC), Philippines, Mindanao, 30 km W of Maramag, Bagongsilang, 1700 m, coll. Bolm, 13–17 May 1996.

Paratypes. – Male ( LMBC), Philippines, Mindanao 30 km W of Maramag, Bagongsilang, 1600 m, coll. Bolm, 28–30 Dec.1990 .

Differential diagnosis. – M. parallelus and M. salvani are very similar in general appearance and structure of male genitalia. The male genitalia of M. salvani have a slightly more slender basal part of the phallus (Figs. 5–8). The close similarity of the male genitalia may indicate their possible sister-relationships. The males of M. parallelus have much larger eyes (diameter 1.28 times interocular distance in M. parallelus versus 1.03 times in M. salvani ).

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, black apically. Head small, hypognathous, including eyes of about similar width as frontal margin of pronotum. Eyes hemispherically prominent, eye diameter 1.28 times frontal interocular distance. Antennae flabellate, lamellae of median antennomeres about 2.3 times longer than body of antennomere. Head and antennae with short, recumbent pubescence. Pronotum flat, 1.52 times wider than long at midline, widest at basal third. Posterior margin of pronotum bisinuate. Elytra almost parallel-sided, slightly widened posteriorly, widest at apical third; 4.6 times longer than width at humeri. Legs lightly compressed, with dense pubescence. Male genitalia with long, slender phallobase, phallus tubular, membranous apically, with slender, rod-like internal sac (Figs. 5–7).

Measurements. – BL 6.85 mm, PL 0.8 mm, PW 1.22 mm, HW 1.3 mm, Edist 0.43 mm, Ediam 0.55 mm.

Distribution. – Philippines: Mindanao.

Etymology. – The specific epithet refers to the slender body and parallel-sided margins of elytra.
