Systaspes Weeks, 1905 is a valid genus

Inspection of Pyrgini trees (Fig. 7) reveals that Antigonus corrosus Mabille, 1878, the type species of Systaspes Weeks, 1905, is a sister to Celotes Godman and Salvin, [1899] (type species Pholisora nessus Edwards, 1877) and is not monophyletic with Antigonus Hübner, [1819] (type species Urbanus erosus Hübner, [1812]). Therefore, we reinstate the genus Systaspes and the combination Systaspes corrosus .
