Banyallarga loxana (Navás)

( Fig. 4B )

Phylloicus loxana Navás 1934: 173 [Type locality: Ecuador: Poujade, 1909; Museum National d'Histoire Naturelle, Paris; male]; Flint, 1983: 77 [to Banyallarga ]; 1996: 424 [distribution]; Prather 2004 [redescription of male and female; review of the genus].

This species is the largest in the genus; size is sufficient to separate it from other species of the genus. The apex of tergum X is narrow and notched ( Fig. 4B : tx), which is another diagnostic character of the species. The female was associated by Prather (2004) by having characteristics of color, proportion and size similar to those of the male. The larva and pupa have not yet been associated and described. This species is newly recorded from Salta province in northwestern Argentina.

Distribution. Argentina (Tucumán, Salta new record), Bolivia, Ecuador, Perú.
