Mendoparabolina Rusconi, 1951a

Type species. Mendoparabolina pirquinensis Rusconi, 1951a , by monotypy, from El Relincho Formation, Cerro Pelado, Mendoza, Argentina .

Emended diagnosis. The diagnosis of Tortello (2014, 2018) is accepted, with the addition of the sigmoid shape of the S1 and S2 lateral glabellar furrows previously noted by Rusconi (1951a).

Other species. Mendoparabolina brevicauda Rusconi, 1955a ; M. nyensis (Taylor, 1976) .

Discussion. Rusconi (1951a) sketched the original cranidium and associated pygidium of Mendoparabolina pirquinensis , the type species. Subsequently, Shergold et al. (1995, p. 246; Jell and Adrain, 2003) suggested that Mendoparabolina is a junior subjective synonym of Bienvillia Clark, 1924 . Tortello (2014, p. 301–303, figs 6.1, 6.2, 4.5–4.25) photographically illustrated the type material and additional specimens from the El Relincho Formation, Mendoza, Argentina. Based upon the more complete knowledge of M. pirquiensis, Tortello (2014) resurrected Mendoparabolina .
