Paratriasina HE, 1980 (Foraminiferida, Middle Triassic of China): Morphology, Taxonomy, Philogenelsis.- The genus Paratriasina HE, 1980, known so far only from the Middle Triassic of the Eastern Tethys (China) is redescribed and placed into the porcelanaceous superfamily Cornuspiracea SCHULTZE, family Arenovidalinidae ZANINETTI & RETTORI, n. fam., subfamily Paratriasininae ZANINETTI & RETTORI, n. subfam. Indeed, on the basis of a morphological revision, Paratriasina cannot be considered to be either in relationship with Meandrospira (as suggested by HE YAN, 1980, in the original description), or with Triasina (as suggested by LOEBLICH & TAPPAN, 1988). Paratriasina, in our opinion, evolved from Arenovidalina, a Triassic isomorph of the paleozoic genus Hemigordius, as well as Paratriasina is a morphological equivalent of Shanita. Arenovidalina, on the other hand, has to be placed at the origin of the Ophtalmidiidae, which first developed in the Middle Triassic.
