Chiloneus infuscatus: Winkler, 1932: 1468; Dalla Torre et al., 1937: 177; Normand, 1937: 244; Borovec, 2013b: 379.

Type locality. [Algeria] Env. d’Alger (Chevrolat, 1861).

Type material examined. Chiloneus algericus . Lectotype (here designated): 1 spec. (MNHN, Desbrochers coll.), ‘ Alger [hw, red ink] // algiricus m. [hw] // Ex Museo / E. Allard / 1899 [p] // LECTOTYPUS / Chiloneus / algericus Desbr., 1871 / Borovec & Perrin desig. 2015 [p, red] // Chiloneus / infuscatus (Chevr.) / R. Borovec det. 2015 [hw/p]’.

Remarks. The lectotype of Chiloneus algericus is 4.03 mm long. Desbrochers in his original description stated that type material was collected by M. Prophette, although there is a label indicating that this material comes from E. Allard below the syntype specimen. Because the specimen fits the description well and comes from the type locality, we assume the specimen belongs to the syntype series. Among moderately long and slender brownish species with sparsely punctured pronotum this species is easily distinguishable by long, weakly subspatulate erect elytral setae, long and conspicuous also in basal half of elytra.
