Lebinthus miripara Otte & Alexander, 1983: 308 . Robillard & Desutter-Grandcolas 2004: 291. Cigliano et al. 2017 ( Orthoptera Species File Online)

Type material. Male holotype. Australia, A- 694, 85 miles N of Geraldton, WA, 10.v.1969, Alexander & Otte ( ANIC) [examined] . Paratypes (1♀): Australia. Same information as HT ( ANIC) [examined].

Additional material examined. Australia, 50 mi ENE of Meekatharra , WA, 29.iv.1963, 1♀, L.J. Chinnick ( ANIC).

Discussion. Close examination of the type series revealed that the species 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: 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.

The attribution of the species to one of the five genera currently included in the tribe Eurepini is more speculative. Based on head morphology with fastigium three times as wide as scape, it could belong to either Salmanites or Eurepella and differs from Eurepa and Myara . The general shape of male genitalia excludes Myara and Eurepa , but could correspond to Salmanites , Arilpa and Eurepella . Finally, there are strong setae oriented anteriorly on dorso-lateral margins of pseudepiphallus, which is a characteristic of Salmanites and Arilpa (Robillard & Desutter-Grandcolas 2004) . Male FW venation reveals that mirror is entirely absent, which is the only recorded case in Eurepini (even the short winged species in Arilpa and Salmanites possess a mirror cell) ( Otte & Alexander 1983). Female ovipositor as long as FIII points toward Eurepa , Myara or Salmanites . In conclusion, the species could either correspond to a new genus, given the original combination of characters, or to a very diverging species of Salmanites . In a conservative way, we consider it as Salmanites miripara n. comb., but this hypothesis will have to be tested in forthcoming revisions of the Eurepini genera and with molecular evidence.
