Gnomidolon incisum Napp & Martins, 1985: 127 ; Joly, 1991: 24; Monné, 1993: 13 (cat.); Monné & Giesbert, 1994: 67 (checklist); Monné, 2005: 310 (cat.); Martins, 2006: 147; Monné & Hovore, 2006: 86 (checklist); Monné, 2022: 492 (cat.).

Gnomidolon incisum is known only from its type-locality in Venezuela ( Napp & Martins 1985). We examined a female specimen from Trinidad and Tobago ( Fig. 1 ). This specimen differs from the type material (paratype illustrated in Fig. 2 ) by the scape orangish (dark reddish brown in the holotype and paratype), and elytra without dark band projected toward anterior third along suture (present in the holotype and paratype). As there are no morphological structures differentiating the specimens, we concluded these are just chromatic variations. The length of the inner spine of the left metafemur is considerably different in the specimen from Trinidad and Tobago ( Fig. 3 ); however, it varies within the same specimen and, in fact, the length of the inner spine of the right metafemur ( Fig. 4 ) agrees well with that in the paratype of G. incisum ( Fig. 5 ). Therefore, this characteristic is variable intraspecifically .
