( Fig. 3 View FIGURES 1 – 9 )

Agorea (sic) nigrostriata ( Rothschild, 1909a: 291) was described based on a female holotype from Tucumán, Argentina, currently deposited in NHUK ( Fig. 3 View FIGURES 1 – 9 ). Its habitus and morphological traits, such as abdominal coremata as long tubes, sacculus and costa separated, spine-shaped cornuti in vesica and two star-shaped signa in corpus bursae, are more similar to that of the type species of Biturix ( B. diversipes Walker, 1855 , illustrated by Vincent & Laguerre 2014) than to that of the type species of Agaraea View in CoL ( A. longicornis ) ( Figs. 10–14 View FIGURES 10 – 27. 10 – 14 ). In fact, the male and female genitalia are very similar to Biturix rectilinea ( Burmeister, 1878) (Beccacece & Navarro 2014) . The distinction between Agaraea View in CoL and Biturix is not well established. Forbes (1939) proposed a differentiation of these genera based only on the morphology of the proboscis. It is necessary to review both genera for a clear differentiation. The complex uncus and the abdominal coremata in male, the signa and pheromone glands in female presented in Biturix may be important diagnostic characters. However, the habitus of both type-species are quite different, which justifies the existence of both genera as separate taxa, and the new combination here proposed.
