  Type species:

   Paralasonia australis Muir, 1924 by monotypy.

Introduction

This genus may be synonymous with Busas Jacobi. Both species have similar venation and the features of the head structure used to differentiate the genera are found in various combinations in the Australian species, particularly in several undescribed species. Pending a comprehensive revision of the Australian Gaetuliini, the two genera are retained and most readily differentiated on the shape of the tegmen which is narrow elongate with the apex acute in known species of Paralasonia.

Diagnosis

Tegmina narrow, pointed at apex. Costal area short and narrow with three or four crossveins; Sc + R joined to apex of costal membrane level with apex of clavus, M fork slightly more distad and Cu fork slightly more basad; from the costal area to apex of clavus there is a row of apical cells subequal in length. Wings small, one third the length of tegmen. Head as broad as, or slightly broader than, the thorax; vertex subquadrate, apex slightly broader than base, slightly rounded with the tumid frons projecting, base slightly excavate, sides straight with slight carinae, middle without carina. Frons shorter than wide, especially on the middle line, frontoclypeal suture arcuate, somewhat obscure, sides of frons subparallel to near apex, where they converge slightly, the middle of the frons tumid; clypeus without carinae. pronotum short, hind margin widely angularly emarginate, tricarinate, the lateral carinae curved, not reaching hind margin. Mesonotum broader than long, obscurely tricarinate. Hind tarsi short, basitarsus wide, swollen. Antennae small, first segment very short, second segment about as long as wide (Muir 1924).
