Introduction

This genus was synonymised with Atracis Stål by Medler (1988). Medler's action was based on Melichar's (1902) placement of the type species of Atracis, Flata pyralis Guérin-Méneville, into Uxantis. Unfortunately, Medler (1988) used the phrase "pyralis sensu Melichar" which implies that he believed Melichar's (1902) recognition of pyralis differed from that of previous authors. If this is the case, then the type species of Atracis is not the same species as the one Melichar (1902) transferred to Uxantis and Medler's (1988) synonymy is invalid. In any case, Medler's synonymy was a nomenclatural action rather than a taxonomic one. The species which were previously placed in Atracis were transfered to a new generic name, Staliana, by Medler and all species previously placed in Uxantis became species of Atracis. It is significant to note that Melichar (1923) listed F. pyralis as a species of Atracis rather than Uxantis. Because of the doubt about Melichar's (1902) identification of Flata pyralis, the different generic placement of the species by Melichar (1923) and the confusion to generic identities created by Medler's synonymy of Uxantis with Atracis, this synonymy is not followed here.

Diagnosis

Genre caractérisé par la cellule subcostale (cellule limitée par les radius 1 et 2), courbée en arrière et en dehors et fermée par une nervure transversale droite ou arquée, elle est souvent assez large, quelquefois plus large que la cellule costale. Vertex à peine prolongé, droit en avant ou légèrement arrondi, rarement anguleux. Front allongé, présentant une carène médiane. Elytres plus ou moins hyalins, membrane costale large, plus large que la cellule costale, traversée par des nervures transversales simples régulières. Nervures de la cellule costale rarement simples, sans anastomoses; dans ce cas, la cellule médiane du clavus (cellules comprises entre les branches anales) est distinctement étranglée au milieu et ordinairement marquée par une courte nervure transversale. Une seule épine sur les tibias postérieurs (Melichar 1923).
