Type material. Holotype female (INPA-COL 002860) from BRAZIL, Amazonas: Manaus, ZF-2, km 14, 2°35’21”S 60°06’55”W, “ Malaise Grande, lado poente,” 24 m, 19.IX–3.X.2017, J.A. Rafael leg. (INPA).
Etymology. This species is named in honor to Dr. Nelson Papavero for his long contribution to the dipterology and systematics in general.
Remarks. Tropidion papaveroi sp. nov. is similar to Tropidion persimile (Martins, 1960) (Fig. 75) but differs as follows: widest area of upper eye lobes with three rows of ommatidia; elytra without transverse whitish band between anterior dark area and posterior orangish area; and outer apical angle of elytra with long spine. In T. persimile, the widest area of the upper eye lobes has four rows of ommatidia, the elytra have a transverse whitish band between the anterior dark area and the light apical area, and the elytral apex is not spiniform on the outer angle.
The new species can be included in the alternative of couplet “5” from Martins & Galileo (2007) (translated; modified):
