Remarks

Similarly to Phanaeus meliabeus above, dissent exists in the literature about the microtaxonomy of P. prasinus . Edmonds (1994) noted a considerable degree of polychromatism in the species, one with a seemingly important geographical component. In spite of that, he treated the species as monobasic. Arnaud (2002b), in contrast, delimited four subspecies, all corresponding to supposedly distinct geographical races. From west to east, we have first Phanaeus prasinus prasinus , characterised by its uniform dark green colouration and found across the Cordillera Oriental of the Colombian Andes as well as in the Venezuelan states of Aragua and Amazonas; then, P. prasinus lugens , completely dull black and endemic to the Cordillera de Mérida of Venezuela; P. prasinus jolyi , characterised by its coppery colouration and known exclusively from the state of Bolívar; and, finally, the Trinidad island endemic P. prasinus trinidadensis Arnaud, 2001 , distinguished by its uniform dark blue colour. The truth of the matter, nevertheless, is that very little is still known about the chromatic population structure of the species and Arnaud’s description should be taken cautiously. Edmonds & Zídek (2012), though with evident hesitation, synonymised the subspecific names and treated P. prasinus once more as monobasic. For this catalogue, we have chosen to follow Arnaud’s classification, the one advocated by the senior author, FZVM. But the second author, MC, in line with his stance on P. meleagris above, would like to reiterate his objection to purely descriptive subspecific classifications such as Arnaud’s, those established simply to reflect geographical variation of phenotypic characters and lacking a commitment to the naturalness of the delimited taxa (see Cupello et al. 2021b).
