Remarks. The lectotype of Sciaphilus minutissimus is 2.50 mm long; it lacks left antenna and left hind leg. The lectotype of Sciaphilus subannulipes is 3.06 mm long; it lacks left antennal club, right protibia with tarsus and right middle leg. The lectotype of Desbrochersella nitidipennis is 2.88 mm long; it lacks right last two antennal segments with club and last two tarsal segments in left metatarsus. All three lectotypes are remounted by us with genitalia extracted. Desbrochersella nitidipennis was overlooked in all three important catalogues (Winkler 1932, Dalla Torre et al. 1937, Borovec 2013) and also in the Desbrochersella revision ( González 1970). Chiloneus minutissimus resembles C. sitonoides ( Reitter, 1915) by brownish black long oval elytra and finely punctured pronotum. Chiloneus minutissimus can be distinguished from it by appressed elytral scales wide and drop-shaped and the longer and more slender rostrum.
