Distribution: Originally described from England. Previously reported from the Falkland Islands (Starý & Block 1996). Although the genus Tectocepheus was recorded in Argentina no assignment to species or subspecies was given (Hammer 1958; Hammer 1962 b; Baranek 1988; Salazar Martínez et al. 2007) until recently when T. minor was recorded in the province of Buenos Aires (Fredes & Martínez 2008) and T. velatus in the province of Misiones (Martinez et al. 2009). First record for the province of Rio Negro.
