Type locality. Portugal [in description] (Tournier, 1874).
Type material examined. Chiloneus chevrolati. Lectotype (here designated): 1 spec. (MNHN, Tournier coll.), ‘ Tanger / Olcèse [hw] // type [hw, yellow] // LECTOTYPUS / Chiloneus / chevrolati Tourn., 1874 / Borovec & Perrin desig. 2015 [p, red]’. Paralectotypes: 4 spec. on 2 pins (MNHN, Tournier coll.), 1 spec. (MNHN, Pic coll.), the same data as lectotype, but ‘PARALECTOTYPUS’.
Holcorhinus parvus. Lectotype (here designated): 1 spec. (SDEI, Stierlin coll.), ‘ Maroc [p] // Coll. Stierlin [p] // Syntypus [p, red] // H. parvus / Stl. [hw, blue margin] // coll. DEI / Eberswalde [p] // Not Holcorhinini / J. Pelletier det. [p] // Holcorhinus / parvus / Strl. [hw] // LECTOTYPUS / Holcorhinus / parvus Stierlin, 1899 / R. Borovec desig. 2015 [p, red] // Chiloneus / chevrolati Tournier / R. Borovec det. 2015 [p]’. Paralectotype: 1 spec. (SDEI, Stierlin coll.), the same data as lectotype, copied from original lectotype labels, but ‘ PARALECTOTYPUS / Holcorhinus / parvus Stierlin, 1899 / R. Borovec desig. 2015 [p, red]’.
Rhinochrosis subglobatus. 1 spec. (MNHN, Hoffmann coll.), ‘II.900 / Tanger [hw] // subglobatus Desbr. [hw]’. 1 spec. (MNHN, Hoffmann coll.), ‘ Tanger / Maroc [hw]’.
Additional material examined. 1 spec., Morocco, Ber Rechid, 1.1922, Antoine (MNHN).
Remarks. The lectotype of Chiloneus chevrolati is 3.69 mm long. The lectotype of Holcorhinus parvus is 3.06 mm long, and it lacks the right antennal funicle and club. All material of this species is known only from Morocco, a report by Tournier in his original description of finding it in Portugal was never confirmed. Because five specimens from Morocco deposited in Tournier’s collection are labelled as types, it is possible that the locality " Portugal " in Tournier’s description is mistaken, although the yellow labels with indication “ type ” were written and added subsequently by Pic who bought the Tournier collection. In the small short-oval body lacking conspicuous long raised setae C. chevrolati somewhat resembles C. pertusicollis (Fairmaire, 1868). From this species it is easily distinguished by its body brownish, less vaulted and protruding eyes and shorter and wider rostrum.
