Chlerogella clidemiae Engel, 2003a: 2 . Moure et al., 2007: 794.

Holotype. ♀, PANAMÁ: San Blas, 19km N of El Llano [El Llano is in Panamá Province with the collection locality 19km North and just across the border into San Blas Province ], 350m, 31 January 1985, G. de Nevers, on flowers of Clidemia crenulata ( SEMC).

Diagnosis. Chlerogella clidemiae is most similar to C. elongaticeps in that both species are largely amber-yellow (Fig. 7). Th e former differs from the latter most noticeably by the combination of a more elongate head [malar space 68% of compound eye length vs. 25% in C. elongaticeps ; malar space 5.4 times longer than basal mandibular width vs. twice as long in C. elongaticeps (cf. figures 8, 9 vs. 2, 3)], the clypeus below the lower tangent of the compound eyes (Fig. 9), the shorter pronotal upper surface (medially about ocellar diameter in length vs. medially about two ocellar diameters in length in C. elongaticeps ) the more widely spaced mesoscutal punctation, the light reddish brown coloration with faint coppery highlights on the head and mesoscutum, and the larger number of branches to the metatibial spur (five vs. three in C. elongaticeps ).

Description. The description of this species was published only recently and given that no further material has become available I have chosen not to repeat that text here. Refer to Engel (2003a) for a complete description of the holotype.
