Remarks. MARTINS & GALILEO (2005) separated the latter two species as follows [translated]: “ Anelaphus colombi- anus sp.nov is similar to A. subseriatus (Bates, 1885) for which we have examined a specimen from Cundinamarca: Fusagasug (MCNZ). It differs in the antennae as long as the body (in both sexes); pronotum densely pubescent with narrow central band glabrous and punctures feebly visible only in the lateral glabrous areas and the elytral setae very short. In A. subseriatus (female) the antennae reach the elytral apex in posterior quarter; the pronotum is sparsely pubescent (allows you to see the punctures); the pronotal glabrous area is larger, shorter and reaches the middle of the pronotum; the elytral setae, especially near the apex, are longer than the pedicel”. The type series of A. colombianus is composed of a male (holotype) and a female; however, when examining what would be the paratype female, it turned out to be another male. In a female identified as A. colombianus (MZSP) the antennae are short (as in A. subseriatus) and the other characteristics used to differentiate these species are variable and do not separate them. If these species can be differentiated, the characteristics used so far do not allow this; the two species will probably be synonymized.
