Chalepistes asperatus ( Broun, 1914 ) new combination Brachyolus asperatus Broun, 1914 :209 Brachyolus fuscipictus Broun, 1914 :210 new synonym Brachyolus terricola Broun, 1917 :417 new synonym The type specimen of B. asperatus is a male, while those of B. fuscipictus and B. terricola are females. Many of the characters that Broun used to separate the nominal taxa (including elytral breadth and convexity of the elytral disc) are sexually dimorphic in this species. The type specimen of B. fuscipictus is a more abraded specimen than the type of B. terricola .
