Derelomus languidus Fåhraeus, 1844 Fig. 20 Derelomus languidus Fåhraeus, 1844: 93. Derelomus rectirostris Hustache, 1937: 218. Syn. nov. Prosoestus rectirostris – Lepesme 1947 (key, biology). Diagnosis Derelomus languidus can be distinguished by its very long rostrum, almost (♂) or equal (♀) to 2× the length of pronotum in lateral view, and the uniform pale brown color of the integuments, or only with darker shadings on the sides and at the apex of the elytra. This species is similar in size and general aspect to D. strangulatus sp. nov., but in the latter the side of the pronotum is deeply strangled apically (only narrowed in D. languidus).
