description: Chiloneus barbaricus (González, 1970), comb. nov.
Platytarsus vaulogeri Desbrochers des Loges, 1897: 176 (not Chiloneus vaulogeri Pic, 1896), homonym; syn. n. Type locality: Algérie, Oued Riou.
Brachysomus vaulogeri: Winkler, 1932: 1472; Dalla Torre et al., 1937: 175.
Desbrochersella barbarica González, 1970: 55.
Desbrochersella barbarica: Alonso-Zarazaga, 1984: 217; Borovec, 2013b: 379.
Foucartia vaulogeri: Borovec, 2013b: 383.
Type locality. [Algeria] Oran (González, 1970).
Type material examined. Platytarsus vaulogeri. Lectotype (here designated): 1 female (MNHN, Pic coll.), ‘Oued Riou 1894 / de Vauloger [p] // 81 [hw] // Platytarsus / Vaulogeri m. [hw] // Museum Paris / Coll. M. Pic [p] / / LECTOTYPUS / Platytarsus / vaulogeri Desbr., 1897 / non Pic, 1896 / Borovec & Perrin desig. 2015 [p, red] // Chiloneus / barbaricus (González) / Borovec et Perrin det. 2015 [p]’.
Additional material examined. 1 male, Algeria, Prov. d´ Oran, Oued Riou, de Vauloger (MNHN).
Remarks. The lectotype of Platytarsus vaulogeri is 2.81 mm long, remounted by us with genitalia extracted. Desbrochersella barbarica was described by González based on one female from Algeria, Oran (González, 1970). Although we did not examine the holotype, González’s description is very detailed, including measurements and precise figures of important characters and it unambiguously indicates this species is conspecific with Platytarsus vaulogeri, moreover described from the same locality. Also Desbrochers’s label ‘ Platytarsus n. sp. ’, cited by González, leads to the assumption that the holotype of D. barbarica could come from the series of specimens Desbrochers described at the end as P. vaulogeri. However, P. vaulogeri is distinct mainly by two unusual characters: 1. short and fine, appressed elytral setae and semierect, long and slender setae as precisely figured in González’s original description and by 2. slender and long elytra, 1.36-1.41 times as long as wide, and the holotype of D. barbarica has elytra 1.44 times as long as wide. Thus we propose here D. barbarica González, 1970 as a junior subjective synonym of Platytarsus vaulogeri Desbrochers des Loges, 1897, syn. n. Contemporaneously we use this name for that species, because Platytarsus vaulogeri Desbrochers des Loges, 1897 transferred to Chiloneus is a homonym of Chiloneus vaulogeri (Pic, 1896). Chiloneus barbaricus is because of the shiny pronotum with sparse punctures of equal size on the disc similar only to C. tenietensis sp. nov. Distinguishing characters between these two species are stated below, in the description of C. tenietensis sp. nov.
