( Figs 3 , 5L )

Wohlfahrtia indigens Villeneuve, 1928: 49 . Algeria, Laghouat.

Wohlfahrtia aethiopica Villeneuve, 1928: 50 . Somalia, Bulhar.

Distribution. Palaearctic—Afghanistan, Algeria, Canary Islands, Egypt, Iran, Iraq, Israel, Jordan, Morocco, Oman, Saudi Arabia, Tajikistan, Turkmenistan, United Arab Emirates, UZbekistan; Afrotropical—Chad, Ethiopia, Nigeria, Somalia.

Remarks. The nominal taXon Wohlfahrtia triquetra Séguy, 1933 had not been revised since its proposal, and Séguy’s original figure, showing male terminalia with a highly characteristic phallus equipped with a unique, abruptly recurved apical segment (“prépuce”, see Séguy 1933: fig. 15), has been reproduced in subsequent taXonomic treatments ( Salem 1938; Séguy 1941; Verves 1985). Séguy (1933: 127) mentions one female from “Silet, Ahaggar occidental, 12-Xii-1927 ” [ Algeria] as well as two males “capturés par M. DALLONI, en janvier, dans l’est du Tibesti, auX environs de Douri” ( Chad). We have recovered and eXamined the male dissected and illustrated by Séguy (1933) and deposited in MNHN ( Fig. 3C ), and we herewith designate this specimen as lectotype, with the type locality restricted accordingly. The specimen has been identified by us as Wohlfahrtia indigens . The distal part of the phallus is evidently broken, which probably occurred during slide-mount preparation of the male terminalia. The shape of the cercus, surstylus, and gonites; the position of the postgonite bristle; and the dorsal curvature of the phallus are here considered a good match with Wohlfahrtia indigens ( Figs 3C , 5L ). The lectotype is labelled (top to bottom): “ triquetra [black handwriting] / É. SÉGUY det. 19 [black print] // MUSÉUM PARIS / TIBESTI E / MISSION DALLONI / 1931 [black print on blue label] // TYPE [black print on red label] // triquetra / prep. micr. / No. 164 / 165 [black handwriting] // JANVIER // ENV DOURI [black print on blue label]” ( Fig. 3D ).
