Macrolycus extrusus sp. nov. (Figs 25, 31, 32, 47)

Type material. Holotype, male, NE Laos, Phou Pan Mt. 1300–1900 m, 1.–15. v. 2010, C. Holzschuh (LMBC).

Diagnosis. This species is similar to M. praecellens, but can be distinguished by the presence of the short lamella on the antennomere 3 and the less expanded apex of the aedeagus (Figs 31, 47). The apical part of aedeagus is wider than that of M. praecellens in ventral view (Fig. 32).

Description (holotype). Body medium-sized, dark brown, pronotum and elytra uniformly orange (Fig. 25). Head small, antennal tubercles inconspicuous. Antennae overlapping two thirds of elytra, antennomere 3 with short lamella (Fig. 47). Antennomeres 4–11 lamellate. Pronotum transverse, anterior margin protruding anteriorly, lateral and posterior margins sinuate. Anterior angles of pronotum inconspicuous, obtuse, posterior angles acute (Fig. 25). Scutellum orange brown, slightly emarginate at apex. Elytra subparallel. Elytral costa 2 much stouter than costae 1 and 3–4. Costal interstices irregularly punctured, covered with dense orange pubescence. Aedeagus without paramerae, median lobe slender, sinuate; apex of median lobe strongly expanded ventrally, with narrow decumbent lamella (Figs 31, 32).

Measurements. Length 11.20 mm, width at humeri 2.80 mm, pronotum length/width 1.90/2.30 mm.

Distribution. Laos, known only from the type locality.

Etymology. The specific name refers to the expanded apex of the phallus.
