Etymology
The specific name is derived from the Greek for “without light” (aphos )), referring to the dark colouration of this species with respect to the other Heteromeringia with four fronto-orbitals.
Holotype: BRAZIL. R. J. Nova Friburgo, 10km S, “Sitio Edelweiss”, Malaise head, 1-28.ii.1990, S.A. Marshall (1 , QBUM).
Comments
Within the Heteromeringia czernyi group, H. aphotisma , like H. czernyiczernyi and H. flavipes , has retained dark colouration and an upcurved bristle in the posterodorsal corner of the anepisternum. Unlike these two dark species, however, H. aphotisma also has an additional reclinate fronto-orbital bristle (synapomorphic of the rest of the group), entirely dusky wings, brown legs (excluding the mid and hind tarsi) and a much darker head, easily separating it.
