Diagnosis: The male of this species is readily recognised by the stout gonopods, which in lateral view are truncate and expanded apically, and by cerci that are angled ventrad near their bases. The gonopods of this species resemble those of
A. evansi
in each having a small setose basal lobe, although this is little more than a small swelling in
A. stclairae
. Both species have tiny, apically rounded papillae medially on the phallic apparatus.
Forewing length: Male 2.5–4.0 mm; female
3.2–4.6 mm
.
Male genitalia: Abdominal sternite VI process stout, curved caudad. In lateral view, abdominal segment IX deeply triangular, blunt anterolaterally. Segment X membranous, rounded, shorter than gonopods. In lateral view cerci each with basal angle, distal to which dorsal and ventral margins parallel, apex truncate. Gonopods stout, length about twice width, apically truncate, each with 2 sclerotised teeth subapically on inner side and small basal process on inner mesal margin. Phallic apparatus with 2 stout dorsal spines and paired membranous striated parameres, at level of constriction of which are 4 small, apically rounded papillae.
Female: Abdominal sternite VI with small mesal spur. Segment VIII darkly sclerotised.
Etymology: Named for Ros St Clair, one of the party who collected the specimens.
Distribution: Known only from the Barrington Tops area of northeastern New South
Wales
