Discussion. Close examination of the type series revealed that this species also belongs to the tribe Eurepini  , based on the definition of the eneopterine tribes and the key of Robillard (2006). The following characters were examined to support this transfer as for L. miripara  : inner tympanum absent, membrane of outer tympanum smooth, male FW venation with CuP extending posteriorly beyond file level, male subgenital plate without swellings on dorsal margin; male genitalia with ramal plates, lateral arms of endophallic sclerite directly prolonged by sclerotization of ectophallic fold, apex of ventral valve of female ovipositor entirely covered by dorsal valves. In addition, the epistomal suture on face is interrupted between the tentorial insertions, with a transversal furrow underlying the median ocellus, which is only found in Eurepini  genera.

As for the previous species, the attribution of the species to one of the five Eurepini  genera is very speculative. Male FW venation with a small mirror, not rounded, points toward Salmanites  and Arilpa  . The female type has no wings ( Chopard 1951; Figs. 3A,B,E View Figure ). However female non-type specimens all show wings reaching abdomen midlength ( Fig. 3F View Figure ), which may indicate that the species is winged but that Chopard’s allotype lost its wings; it remains compatible with Salmanites  and some Eurepa  species, which include winged and almost apterous species ( Otte & Alexander 1983).The large size of the ovipositor (2.5 longer than FIII) would exclude Eurepella  and Arilpa  , and is compatible with Eurepa  and Myara  . The general shape of the male genitalia and in particular the shape of the pseudepiphallic parameres with anterior projections is however clearly a characteristic of Eurepa  . In conclusion, the species could either correspond to a new genus, given the original combination of characters, or to a very diverging species of Eurepa  or Salmanites  . In a conservative way, we consider the species as Eurepa bifasciata  n. comb., but this hypothesis will have to be tested in a forthcoming revision of the Eurepini  genera and with molecular evidence.
