( Figs. 19–20 )

Records. SMNK: ♂, 230 m, malaise trap, V.2013, leg. E. Diller (SMNK-Mant 12825) . ZSM: ♂, 260 m, 22.XI.– 07.XII.2008, leg. E. Diller ( Figs. 19–20 ) .

Distribution. Peru.

Remarks. The number of species belonging to this genus is unclear since specimens from South American localities outside Mesoamerica and Colombia have been investigated (e. g. Venezuela, Ehrmann 2002), and Mantillica sialidea Westwood, 1889 has been transferred to Thrinaconyx by Agudelo & Rafael (2014) without clearly working out the differences between the three now accepted species. Our specimen is closest to Th. fumosus Saussure & Zehntner, 1894 from Central America, being distinguished from males of that species by a very distinct, mediumsized anteroventral spine on the foretibiae situated between the two long anteroventral spines (the same structure being absent in topotypical males but not females of Th. fumosus ), and by more slender tegmina. At the same time it lacks the small anteroventral spine in the proximal half of the tibia present in Th. fumosus ( Fig. 20 ). It differs from Th. sialidea by the possession of a small tubercle on the dorsal side of the base of the median ocellus. Whether these differences just reflect the variability of a widespread Th. fumosus or justify the specific separation of Peruvian specimens must await study of more extensive series of specimens of both sexes.

Rivera & Vergara-Cobián (2017) did not list any species of this genus from Peru, but unidentified specimens were mentioned by Agudelo & Rafael (2014).
