Abstract

PIZZARRO-ARAYA, Jaime  and  FLORES, Gustavo E.. The systematic position of Geoborus lineatus comb. nov. (ex. Gyriosomus ) (Coleoptera: Tenebrionidae). Rev. Soc. Entomol. Argent. [online]. 2006, vol.65, n.3-4, pp.93-98. ISSN 0373-5680.

The systematic placement of Gyriosomus lineatus Guérin-Méneville, 1834 is resolved. Geoborus costatus Blanchard, 1847 (Pimeliinae: Epitragini) is determined to be a junior synonym of Gyriosomus lineatus Guérin-Méneville 1834 (Pimeliinae: Nycteliini) and the new combination Geoborus lineatus (Guérin-Méneville, 1834) (Epitragini) is proposed. Geoborus costatus is subsequently designated the type species for Geoborus Blanchard, 1847. Comments and photographs of the type material are included. Comments of the distribution and habitat of the species are given.

Keywords : Tenebrionidae; Gyriosomus; Epitragini; Geoborus; Classification.
