Introduction

This species was known only from the female holotype from Dongara, Western Australia until Fletcher (2007) described the male from Barrow Island. It is a small squat species with fairly plain colouring.

Diagnosis

Head greenish yellow, eyes brown. Pronotum and scutellum concolorous with the head. Tegmen hyaline green, the veins indistinctly bordered by fine hairs. Thorax and abdomen ventral surface pale greenish yellow. Length 2.8 mm (Evans 1942).

Webb (1983) noted that the female genitalia of P. viridiceps are similar to those of P. candidus (Evans), also from Western Australia. The male genitalia, however, indicate a closer affinity with P. hyleorais (Kirkaldy) which has a wide distribution across northern Australia from Western Australia to Queensland, and P. nymphias (Kirkaldy) from Queensland and New South Wales. It differs from both species in its smaller size, in lacking dark markings and in the shape of the subgenital plates and aedeagus. It is similar in the structure of the paramere which has the apex acute and directed medially and a preapical process extending laterally (Fletcher 2007).
