Chlamydocassis (Ceratocassis) bicornuta ( Boheman, 1850) (Goniocheniini) View in CoL

Published record. Indiana (Bඎඓඓං 1988, = C.laticollis , see remarks under that species).

Distribution. Brazil (Bahia, Ceará, Minas Gerais, Pernambuco) and? Colombia.

Remarks. Distribution of C. bicornuta is here revised as some authors considered C. laticollis a synonym of C. bicornuta (e.g., SඉൺൾඍΗ 1931, Bඎඓඓං 1988); thus, the distribution of the two taxa was mixed. I did not have the opportunity to examine the material Buzzi studied but very likely some of these specimens belong to C. laticollis and were published earlier by Vංൺඇൺ (1964b). Chlamydocassis bicornuta was described from Bahia and Colombia. Further records from Bahia, Ceará and Minas Gerais (Vංൺඇൺ 1964) are reliable as Viana studied the type material of both taxa. I found two paralectotypes from Colombia in the Zoological Museum in Copenhagen (coll. Westermann) and both morphologically agree with the lectotype; however; their locality data are questionable as such a vicariant distribution is very improbable. Remaining records belong to C. laticollis , and thus São Paulo, Paraguay and Venezuela are removed from the range of C. bicornuta .
