Clavidesmus Dillon and Dillon, 1946: 293 ( Lamiinae : Onciderini )

( Figures 7a–i )

Clavidesmus Dillon and Dillon, 1946: 293 . Type species: Eudesmus heterocerus Buquet, 1852 .

= Orteguaza Lane, 1958: 10 ( Lamiinae : Apomecynini ). Type species: Orteguaza lichenigera Lane, 1958 , by original designation, new synonymy.

Discussion. Lane (1958) described the genus Orteguaza and included two species: O. funeraria ( Fig. 7c ) and O. lichenigera ( Fig. 7f ). Examination of the holotype specimens of O. funeraria and O. lichenigera , as well as the type specimens of all described species of Clavidesmus Dillon and Dillon [ C. chicae Giorgi, 1998 ( Fig. 7a ); C. columbianus Breuning, 1961 ( Fig. 7b ); C. heterocerus (Buquet, 1852) ( Fig. 7d ); C. indistinctus Dillon and Dillon, 1952 ( Fig. 7e ); C. metallicus (Thomson, 1868) ( Fig. 7g ); C. monnei Giorgi, 1998 ( Fig. 7h ); and C. rubigineus Dillon and Dillon, 1949 ( Fig. 7i )] revealed are no characters to separate the two genera. Based on close morphological similarities, Orteguaza is here synonymized with Clavidesmus , creating two new combinations, Clavidesmus funerarius ( Lane, 1958) and Clavidesmus lichenigerus ( Lane, 1958) . The known range of Clavidesmus is extended to Central America ( Costa Rica, Honduras, Nicaragua, and Panama). We believe the genus Clavidesmus is over-split and in need of a taxonomic revision.
