Batrachotetrix cantans Saussure, 1888

Material examined. Namibia, Lüderitzbucht 1925 (1♂, 2♀) (MZUH) .

Remarks. The above listed specimens are fully winged; four species belonging to this genus have tegmina longer than the abdomen: B. braini Uvarov, 1931, B. cantans Saussure, 1888, B. loricatus Saussure, 1884 and B. peringueyi Saussure, 1888 . All occur in South Africa and three ( B. braini, B. cantans and B. peringueyi) in the Cape province of South Africa. It is possible to exclude that the specimen from Namibia is B. braini by its very rugose integuments; following the key of Saussure (1888) it was possible to exclude also B. loricatus, which has brachypterous females. Sulphureous hind wings are typical for B. cantans while B. peringueyi has cerulean wings; Namibian specimens have sulphureous wings. Lüderitzbucht is ca. 800 km from Prieska (the type locality of B. cantans); no fully winged species of this genus was hitherto known from Namibia.
