Chiloneus henoni: Winkler, 1932: 1468 ; Dalla Torre et al., 1937: 176; Normand, 1937: 244; Borovec, 2013b: 379.

Type locality. [ Algeria] Constantine ( Allard, 1869).

Type material examined. 2 syntypes ( SMTD, Faust coll.), ‘small brownish gold label // Algeria Allard / Constantine Allard [hw] // Coll. J. Faust / Ankauf 1900 [p, blue] // Type [p, red] // Staatl. Museum für / Tierkundunde, Dresden [p]’.

Additional material examined. 15 spec., Algeria ( MNHN); 1 spec., Algeria, El-Milia, v.1899, Mol. de Boissy ( MNHN); 1 spec., Algeria ( SMTD); 5 spec., Algeria, Constantine ( SMTD); 3 spec., Tunisia ( SMTD).

Remarks. “ Chiloneus ” henoni , originally described as Sciaphilus , and later listed in all catalogues as Chiloneus clearly differs from all other Chiloneus by the long set of characters used for a genus definition of Chiloneus , as follows: fronto-epistomal area at the same level and with identical structure as epifrons, not separated posteriorly by any carina, not creating shiny unpunctured plate; antennal scrobes in lateral view not curved downwards, create moderately short and wide, straight furrow directed to ventral border of eyes; antennal scapes shorter than funicles; elytra with distinct humeri prominent laterally, at base distinctly wider than base of pronotum; gonocoxites apically rounded, lacking styli; sternite VIII in females with plate small, subtriangular, with distinct basal margin, apodeme not terminated inside of plate. By all these characters, including important characters on female genitalia, “ Chiloneus ” henoni could be transferred to the genus Polydrusus Germar, 1817 , subgenus Leucodrusus Stierlin, 1884 , where it is similar mainly to P. sicanus (Chevrolat, 1860) known from Crete and Sicily, but easily distinguishable from it by for example elytra with more rounded sides and narrower humeri and shorter scrobes in lateral view.
