PARDO-LOCARNO, Luis Carlos  and  VILLALOBOS-MORENO, Alfonso. COLOMBIAN CHIASOGNATHINI: REDESCRIPTION AND ADDITIONS TO THE DISTRIBUTION OF SPHAENOGNATHUS ROTUNDATUS LACROIX AND SPHAENOGNATHUS PRIONOIDES BUQUET (COLEOPTERA: LUCANIDAE). Bol. Cient. Mus. Hist. Nat. Univ. Caldas [online]. 2016, vol.20, n.2, pp.235-249. ISSN 0123-3068.  https://doi.org/10.17151/bccm.2016.20.2.18.

Beetles of the genus Sphaenognathus (Coleoptera: Lucanidae: Chiasognathini) in Colombia, form an eminently tropandean lineage of cold jungles, reason why its distribution shows a very complex insular pattern, little known and that is aggravated by the lack of studies to learn about its ecology and distribution, and the accelerated destruction of such habitats. This research was proposed to redescribe the species S. rotundatus Lacroix and to add geographical records of S. prionoides Buquet. The specimens studied were collected in biodiversity research projects in the Santurban Moor (California, Santander, Colombia). The data suggest the taxonomic validity of S. rotundatus and record it for the first time for Colombia. Likewise, the record of S. Prionoides as typical of the Colombian Eastern Mountain Range on the departments of Cundinamarca, Boyacá and Santander is suggested.

Keywords : beetles; distribution; revalidation of species; Andean region; Colombia.
