Larinus gravidus ( Olivier, 1807)

Figs. 5–6 , 19 .

Lixus gravidus Olivier, 1807: 275 ; pl. 30, fig. 450.

Original description. " L. longirostris fuscus , thoracis lateribus albis, elytris striatis albo pulverulentis. Similis L. Scolymi. Antennae nigrae apice cinereae. Rostrum incurvum cylindricum nigrum basi cinereo pubescens, a basi usque ad insertionem antennarum linea vix elevata; inter antennas foveola oblonga. Thorax punctatus fuscus lateribus albo pubescentibus. Elytra striato-punctata fusca pube alba irrorata. Corpus subtus pedesque fusca cinereo pubescentia. Femora mutica."

Type locality. “Amérique septentrionale”.

Types. In a box in the MNHN recently given by Olivier’s family to the Museum, there is a female bearing the labels “COLLECTION OLIVIER TYPE ” printed on a green round paper, “ Rhinobatus, Gravidus. Ol., C. Olivier, Amer. bor.” handwritten on green paper, and “MUSEUM PARIS, Famille Olivier, leg. 1995”, “ MNHN EC 1940” printed. The specimen, agreeing with both description and type locality is here designated as the lectotype with: “ LECTOTYPUS Ƥ, Lixus gravidus Olivier, Gültekin & Perrin des. 2010”, identified as “ Larinus gravidus (Olivier) , Gültekin det. 2010”. The lectotype is pinned through the right elytron.

Remarks. Description and label data of the type specimen are in accordance with the original description ( Olivier 1807); however, there is no further record about the finding of this species in America ( O’Brien & Wibmer, 1982; Wibmer & O'Brien, 1986). Members of the genus Larinus are not distributed in the Nearctic, Neotropical and Australian regions ( Csiki, 1934), except for species introduced into the United States of America such as L. minutus Gyllenhal, 1835 , L. obtusus Gyllenhal, 1835 and L. curtus Hochhuth, 1851 (Lang et al. 1997; Sobhian & Fornasari, 1994), and into the Australian region, like L. latus (Herbst, 1783) ( Woodburn & Briese, 1996) , for biological control of weeds. Recently an accidental introduction into the United States of L. carlinae ( Olivier, 1807) ( McClay, 1990) [= Larinus planus sensu Germar, 1824 , (not Fabricius, 1792)] (see Gültekin, 2006) was also reported. Consequently, we considered the type locality “Amérique septentrionale” as erroneus, also because L. gravidus ( Olivier, 1807) turns out to be conspecific with L. schoenherri Capiomont, 1874 which is distributed in Spain, Portugal and Algeria ( Csiki, 1934; Alonso-Zarazaga, 2002). Consequently: Larinus gravidus ( Olivier, 1807) [= L. schoenherri Capiomont, 1874 , syn. nov.].
