Etymology. The specific epithet colombiana (nominative, adjective feminine) of this species refers to the country of Colombia, where the type specimens were collected.
Remarks. Hoplopeza colombiana sp. nov. and H. chloropa Bezzi, 1909 share the shiny occiput, but the two species are easily separated by the absence of the row of long spiny setae on the hind basitarsomere in the new species, which is present in H. chloropa. Moreover, in terminalia structures H. colombiana can be differentiated from H. chloropa, by the absence of strong apical spine on the left cercus, which is present in H. chloropa (Rafael 1995, fig. 7).
Hoplopeza colombiana sp. nov. can be differentiated from H. rafaeli sp. nov. by the shiny occiput, which is pruinose in H. rafaeli. In male terminalia, the strong curved spines along the inner margin of the left epandrial lamella are absent in H. colombiana, whereas they are present in H. rafaeli.
