Remarks. The lectotype of Sciaphilus vaulogeri is 2.94 mm long and it is dissected with penis on separate label and with right antenna missing. The lectotype of Sciaphilus alluaudi is 3.63 mm long. One specimen of Chiloneus pilosulus from the Démoflys collection has identical locality and collector, but different date than is stated in the description (‘12–51’ instead of ‘11–1951’); that is why we did not designate it as lectotype. However, that specimen fits the description very well. Sciaphilus alluaudi and Chiloneus pilosulus are clearly conspecific with the lectotype of Sciaphilus vaulogeri and so are junior subjective synonyms. This is an unusual species, very easily separated and different from all others by very short and wide rostrum with short and transverse frontoepistomal area, dorsally separated from rostrum by constriction caused by antennal scrobes and very dense, moderately long semierect elytral setae. The name is a senior homonym of Platytarsus vaulogeri Desbrochers des Loges, 1897.
