Paraleia Tonnoir

Paraleia Tonnoir, 1929: 611 . Type-species, Paraleia fulvescens Tonnoir , by original designation.

Diagnosis. C extending slightly beyond R5, R5 ending rather close to wing apex; Sc complete, ending at C on basal third of wing length; h, Sc, sc-r, Rs and M1+2 without macrotrichia, other veins with dorsal macrotrichia; first sector of Rs transverse or almost transverse; r-m long, almost longitudinal, aligned with second sector of R5, this r-m/R5 system pretty much separated from R1. Medial and cubital forks complete, CuA slightly concave, A1 absent on distal third. Laterotergite and mediotergite bare. Gonocoxite with an extension distal to the base of gonostyle, the inner face typically with numerous short spines; gonostyle elongated, with combs of short spines and a long, preapical spine. Paraleia is unequivocally separated from its closeby relatives in the Leiinae—e.g., Leia , Leiella , Indoleia , Clastobasis , Rondaniella Johannsen , Neoclastobasis Ostroverchova , and Greenomyia Brunetti—by the rm/R5 complex largely displaced from the anterior margin, actually a uniquely derived feature of the genus. The distal projection of the gonocoxite, posterior to the insertion of the gonostyles, bearing a number of spines, sometimes forming combs, also present in the gonostyle, is also a very distinctive of the species of Paraleia .
