Type material. Holotype of Omalium vaulogeri ♂ (Fig. 3;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) 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).
