Type material. Holotype of Omalium vaulogeri ♂ ( Fig. 3 View FIGURES 1–4 ;dissected): TUNISIA: ‘ Kairouan |Tunisie’ <handwritten>, ‘Vaulogeri | Fvl.’ <handwritten>, ‘R.I.Sc.N.B. 17.479 | Omalium [handwritten] | Coll. et. det. A. Fauvel’ <printed>, ‘TYPE’ <red label with thin black margins>, ‘ Omalium | allardi Fairmaire & Brisout de Barveville, 1859 | Shavrin A.V. det.’ <printed> ( IRSNB).

Additional material examined. TUNISIA: 1 ♂: ‘ Tunisie: Mateur C. Rocha’, ‘ G. Fagel det. vaulogeri ?? Fauv. ’ ( IRSNB) .

Remarks. Homalium vaulogeri was originally described based on the holotype from “ Tunisie: Kairouan ”. The study of the holotype ( Fig. 3 View FIGURES 1–4 ) and a comparison with specimens of O. allardi revealed that based on the external morphology and the shape of the aedeagus (Fig. 12), all these specimens are conspecific. Thus, I synonymized it with the latter species. Measurements of the holotype of O. vaulogeri : HW: 0.47; HL: 0.35; OL: 0.12; TL: 0.07; AL: 0.86; PL: 0.40; PWmax: 0.67; PWmin: 0.55; ESL: 0.72; EW: 0.90; AW: 0.89; AedL: 0.44; BL: 2.76. Omalium allardi is a widespread Palaearctic species ( Schülke & Smetana 2015; Shavrin 2025b), also introduced in New Zealand ( Klimaszewski et al. 1996). It is worth noting that it was recorded from North Africa, and known from Morocco, Algeria, Tunisia and Libya ( Schülke & Smetana 2015).
