Lixus rectirostris Faust, 1890

Lixus rectirostris Faust, 1890: 333

Current status: Lixus rectirostris Faust, 1890 is a valid species and is a senior homonym of Lixus rectirostris Desbrochers, 1904 .

Type. In Faust's collection at SMTD, a male fitting the description and with type locality as “Biskra”, bearing the labels: [golden square label, indicating types], “3, Biskra, Bedel”, “ rectirostris Faust ”, is here designated as the lectotype, and has been labeled “ Lectotypus, 3, Lixus rectirostris Faust, Gültekin des. 2008” ( Figs. 1–2 ). A female and a male, bearing the same labels above (a third lacks the golden square), are here designated as paralectotypes, and have been labeled “ Paralectotypus, Ƥ/3, Lixus rectirostris Faust, Gültekin des. 2008”. The lectotype was pinned through the right elytron and the elytra are weakly separated. The right funicle beyond the third segment, left funicle beyond the first segment and left fore tarsus beyond the second segment are missing.

Remarks. The examination of types of both species revealed that Lixus rectirostris Desbrochers, 1904 is conspecific with Lixus rectirostris Faust, 1890 and is also a junior homonym. Since the name Lixus rectirostris was already employed by Faust (1890), the new name Broconius helenae was proposed by Alonso-Zarazaga & Lyal (1999: 189). Moreover Hoffmann (1954) described Lixus rectirostris Faust subsp. infrequens Hoffmann, 1954, from Marrakech, Morocco, which he placed in the subgenus Phillixus , based only on slight body size differences. Thus, Lixus rectirostris Faust, 1890 [= Lixus rectirostris Desbrochers, 1904 nec Faust, hom. et syn. n.; = Lixus rectirostris Faust subsp. infrequens Hoffmann, 1954, syn. n.; = Broconius helenae Alonso-Zarazaga & Lyal, 1999 , comb. et syn. n.]. Body form ( Fig. 3 ), shape of rostrum ( Fig. 4 ), fore tibia ( Fig. 5 ) and aedeagus ( Figs. 6–7 ) address this species to the Lixus rubicundus group.
