  Type data:

   Holotype AM ♂ (coll.: xii.1923, Musgrave & Whitley), Lord Howe Island.

Introduction

Muir (1931) based this species on four male and three female specimens from Lord Howe Island. He stated that the "Type" was in AM with a paratype in BMNH. He did not indicate whether the paratype in BMNH was a male or a female. Donaldson (1983) redescribed the species and examined a paratype female, presumably from AM, but did not indicate how many paratypes were located there. He also stated that the holotype could not be found in AM. Additional non-type material of the species examined by Donaldson (1983) extended the distribution to include Norfolk Island.

Diagnosis

♂: length of body 4.3–6.1 mm, length of tegmen 3.1–4.5 mm; ♀: length of body 4.8–6.9 mm, length of tegmen 3.8–5.5 mm. Ground colour light brown, with or without varying amounts of dark brown to black. These areas are usually as follows: adjacent to posterior margin of vertex, 2 lateral areas near apex of vertex, often extending onto frons, frons usually with 2 lateral areas near apex and also at base, areas often joined laterally and/or medially, frons sometimes mostly black, clypeus and postclypeus varying from ground colour to nearly all black, antennae with slight darkening in basal and apical thirds of segment 2, legs often with dark banding, pronotum normally with dark areas just behind eyes, sometimes 2 dark areas near base and adjacent to posterior edge of lateral carinae, mesonotum normally without dark coloration, though sometimes with dark areas adjacent to carinae, rarely with pronotum and mesonotum nearly all dark, ventral surface variable from pale to nearly all dark, tegmen normally with dark areas at base and near apex of claval suture, in dark specimens various dark areas along veins and on tegmen. Vertex in midline I .4–1.8 x basal width, widest just before rounded apex level with anterior ends of lateral margins; sides concave behind apex and nearly straight at base, converging towards base; posterior margin straight or very slightly convex; submedian carinae uniting and then separating about one-third from apex, apical part often indistinct; basal compartment slightly wider than long. Frons in midline 1.7–1.9 x greatest width; submedian carinae separate for entire length. subparallel medially, converging towards base and apex. Segment 2 of antennae 1.55–1.9 x length of segment 1. Pronotum with median carina distinct. Mesonotum with median carina not reaching posterior margin. Hind tibiae with single lateral spine in addition to basal and apical ones. Tegmen short, reaching anal segment, claval suture present; Cu forked at level of claval fork, each branch reuniting before apex, if not reunited then connected by cross vein near apex; M usually forked near cross veins. rarely unforked, 1 row of cross veins; apical veins simple. Anal segment of ♂ in lateral view with ventrolateral portion strongly produced posteriorly, with evenly rounded apex. Pygofer with median and ventrolateral projections acutely rounded, median projection not reaching level of ventrolateral projections, depressions present between bases of projections. Genital style in ventral view moderately long, robust at base and tapering towards apex. (Donaldson 1983)
