Taxonomic changes of some neotropical species of Arctiini Leach (Lepidoptera: Erebidae: Arctiinae) Author Beccacece, Hernán Mario Author Zapata, Adriana Inés text Zootaxa 2017 4272 3 421 429 journal article 32936 10.11646/zootaxa.4272.3.7 1f75966c-2b88-4148-814c-ace21e8c0d2b 1175-5326 892434 114FC930-2AAF-4BB1-ADF8-CF912E15D74A Biturix nigrostriata (Rothschild, 1909) comb. n. ( Fig. 3 ) Agorea (sic) nigrostriata ( Rothschild, 1909a: 291 ) was described based on a female holotype from Tucumán , Argentina , currently deposited in NHUK ( Fig. 3 ). 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 ( A. longicornis ) ( Figs. 10–14 ). In fact, the male and female genitalia are very similar to Biturix rectilinea ( Burmeister, 1878 ) (Beccacece & Navarro 2014) . The distinction between Agaraea 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. Material examined.
