Lixus recurvus Olivier, 1807: 237 ; pl. 21, fig. 287.

Original description. " L. longirostris , niger, elytris striatis acutis flavo pulverulentis. Lixo paraplectico major et crassior. Antennae tenues, nigrae. Rostrum cylindricum, thorace longius, nigrum. Thorax rugosus, niger, immaculatus. Elytra vix punctato-striata, flavo pulverulenta, apice acuto reflexo. Pedes flavo pubescentes femoribus muticis".

Type locality. “ Georgie ”.

Types. In a box in the MNHN recently given by Olivier’s family to the Museum, a female bears the labels “COLLECTION OLIVIER TYPE ” printed on green round paper, and “ Lixus, Recurvus. Ol., C. Olivier, Georg. Asia.” handwritten, “MUSEUM PARIS, Famille Olivier, leg. 1995”and “ MNHN EC 1944” printed. The specimen, agreeing with both description and type locality is here designated as the lectotype with: “ LECTOTYPUS Ƥ, Lixus recurvus Olivier, Gültekin & Perrin des. 2010”. This female is pinned through the right elytron causing the elytra to divaricate, and its right funicle, left funicle beyond the first segment, left fore claw segment, right middle tarsus beyond segment 2 are missing.

Remarks. This name is listed as a questionable synonym of Lixus furcatus Olivier, 1807 in Csiki (1934). Lixus recurvus Olivier, 1807 is removed from synonymy and placed in the Lixus iridis group by Gültekin & Korotyaev (in press). The above lectotype designation confirmed that Lixus recurvus Olivier, 1807 is the same species to Lixus nordmanni Hochhuth, 1847 , and since the younger name does not fully meet the requirements of article 23.9.1.2 of the Code (ICZN 1999), the following synonymy is here established: Lixus recurvus Olivier, 1807 [= L. nordmanni Hochhuth, 1847 , syn. nov.]. Lixus recurvus is closely related to L. iridis , but its rostrum is longer, and the apex of its aedeagus is round instead of triangular.
