  Type species:

   Stenalsella testacea Evans, 1966 by original designation.

 

Introduction

This monotypic endemic genus is closely related to Alseis Kirkaldy and Macroceps Signoret but is unusual in having the claval veins united to form a Y-vein. It is only known from a few coastal localities in the SE of Queensland and NE of New South Wales. Evans (1966) gives "National Park, New South Wales" as part of the distribution but the specimen in the J.W. Evans collection on which this record is based was collected at National Park, Queensland.

Diagnosis

The face of the head is wider than long and the labium extends to between the middle coxae. The anteclypeus and lora, which are slightly declivous anteriorly, are on the same plane as the postclypeus. The postclypeus is almost flat and an obscure transverse epistomal suture is discernible. This is in alignment with the strong transverse antennal ledges. The frons is rectangular and the hind margin, which is discernible, is separate from the angulate transverse facial ridge. The ocelli, which lie in shallow depressions immediately posterior to this ridge, are in alignment with the antennae and are directed anteriorly and not facially. The crown is sometimes narrowly produced so that its length in the centre may be equal to its length against the eyes. The pronotum, which is slightly declivous and anteriorly depressed, has deep transverse striations and the scutellum is slightly raised posteriorly. In the tegmina, the anal veins form a Y-vein. In the female, the ovipositor extends slightly beyond the folded tegmina (Evans 1966).
