Type material examined.

Lectotype of Callimerus trifasciatus Schenkling designated here: "Nuova Guinea, Fly River, L. M. D. Albertis, 1876-77 / Typus / trifasciatus Schenkl. / C. trifasciatus Schklg, Typus! N. Guinea: Fly riv., L.M. D’Albertis, 6462 [hw. by Raffaello Gestro]" (MCSN, ♀; Figs 73-75).

Note on Type material.

The name-bearing type of trifasciatus was not fixed in the original publication. We designate the only specimen found in MCSN as lectotype to express the taxonomic purpose of fixing the name to a single specimen and preventing further uncertainty regarding the taxon to which the name is applied [The red lectotype label will be sent to MCSN after this paper published].

Taxonomic position.

This species is excluded from the genus Callimerus for its following characters: labrum deeply incised; eyes deeply emarginated near the antennal insertions; elytral punctures in rows; elytra clothed with unspecialized de scent setae (not scales); the first tarsomeres very small and invisible from dorsal view; metatibia with 2 spurs in apex; metatarsi having pulvillus on tarsomere IV (in Callimerus labrum with apex straight or very slightly emarginated in the middle; eyes very slightly emarginated at antennal insertions; elytral punctures not in rows; elytra with scales or glabrous; the first tarsomeres of normal size, not shorter than the second tarsomeres; metatibia with 1 spur in apex; metatarsi having pulvilli on tarsomere I–IV). Furthermore, we consider it should be assigned in the genus Corynommadius Schenkling, 1899a. Its closest relative is Corynommadius speciosus Schenkling, 1899a, the type species of Corynommadius Schenkling; the difference of these two species only shows in variation of anterior black spot on elytron (Fig. 73; Gerstmeier 2002: 425, 432, fig. 2).
