Acostatrichia elvesta Oláh & Flint 2012

Fig. 16 View FIGURE 16

Acostatrichia elvesta Oláh & Flint 2012: 146 , figs. 12–15, male; type locality: Brazil, Rondonia State, creek, 8 km South Cacaulandia; type depository: NMNH [not found].

Remarks. This species was described from only one specimen collected in Northern Brazil.Although in the original description, the unique specimen, the holotype, was said to be in the NMNH, it was not found in this collection. Based on the features provided in the original description, this species agrees with the definition of the A. plaumanni Group as I proposed here. The male has a short costal bulla on each forewing, segment VII bears a double ventral process, segment IX bears paired dorsolateral processes, and the inferior appendages are relatively short and not fused mesally. Acostatrichia elvesta and A. araca sp. nov. share the condition of having two ocelli, whereas all other Acostatrichia species have three. The male genitalia of these two species are quite different, especially with segment IX apparently bearing two pairs of dorsolateral processes in A. elvesta and the subgenital plate being divided longitudinally.
