Contribution to the knowledge of Macrolycini with description of Calcaeron, new genus (Coleoptera, Lycidae)

Abstract

The morphology of the tribe Macrolycini of net-winged beetles (Lycidae) is studied. The subtribe Dilophotina Kleine, nom. rev. is revalidated from synonymy with Macrolycini. A new genus Calcaeron gen. n. and five new species: Mesolycus hubeicus, M. nanensis, M. murzini, Calcaeron sundaicus and C. baluensis are described. Mesolycus Gorham nom. rev. is revalidated from synonymy with Dilophotes, while Flabellodilophotes Pic, 1912 and Biphilodes Kazantsev, 2000 are synonymized with Mesolycus. Dilophotes moxiensis Bic is found to be synonymous to Mesolycus ilyai (Kazantsev). M. mediozonatus (Nakane), stat. n. is raised to species level. The following taxa are transferred to Mesolycus: Dilophotes pygmaeus Waterhouse, D. shelfordi Bourgeois, D. discoidalis Pic, D. ater Pic, D. tricostatus Kleine, D. ilyai Kazantsev, D. qinlinganus Kazantsev, D. tibetanus Kazantsev, D. berezowskii Kazantsev, D. sausai Bic, D. laosensis Bic, D. bolavensis Bic, D. jendeki Bic, D. holzschuhi Bic, D. bhutanensis Bic and Flabellodilophotes obscurus Pic. The phylogeny of Macrolycini is discussed and a key to the genera of the tribe is provided.

New and little known net-winged beetles (Coleoptera: Lycidae) from the Crocker Range Mountains, Sabah, East Malaysia

“…Libnetus muscosus sp.n. is apparently related to L. gununganus Kazantsev, 2004, separable by the noticeably smaller pronotum, longer and distinctly widened distally elytra and certain details of the aedeagus, such as clawed ventral processes, evenly bent in lateral aspect median spike, parameres conspicuously divided by suture at proximal opening, etc. .…”

“…Pyrotes Kazantsev, 2004 Type species: Pyropterus sculpturatus C.O. Waterhouse, 1878 (original designation).…”

“…However, when it came to studying material from the montane tropical rainforest, at higher elevation, especially on Mount Kinabalu [Pic, 1912[Pic, , 1936Kleine, 1932Kleine, , 1933a, almost all discovered lycid taxa turned out to be local endemics. Further contributions to the knowledge of the Borneo montane rainforest Lycidae were only adding data to prove it [Kazantsev, 1997;1998, 2003, 2004, 2009, 2014Malohlava, Bocák, 2009, 2011.…”
