Cyrtomenus (Syllobus) grossus ; Froeschner, 1960: 520.

Material examined: 2 specimens, RJ, Itatiaia, Estação Biologica, 25-Jan-1932, Zikán col., MNRJ ; 1 specimen, Itatiaia, Aug-1933, Zikán col., MNRJ ; 1♀, RS, Porto Alegre, Serro Azul , MCNZ .

Distribution: Mexico, Guatemala, Brazil new rec. (RJ, RS), Ecuador.

Remarks: The apex of the labium surpassing the posterior coxae and the very broad head, marked by the interocular width distinctly greater than length of head, allows the recognition of C. grossus among the other species of the genus, even C. teter , the more closely allied species according Froeschner (1960).
