Distribution. Indonesia ( Moluccas, Aru Islands), Papua New Guinea, north-east of Australia.

Diagnostic characters: Postfrons with dark T-mark. Both Hw generally with space between CuP and A1 basally not expanded and without double cells in proximal half. Generally no more than 10 denticles along posterior portion of genital fossa not strictly formatted or densely set, somewhat irregular, generally no denticles along anterior portion. Superior anal appendages very slender, slightly sinuous, clubbed with subapical portion not wider than 1.5 times basal width and with apex narrowly curved postero-laterally into a short, not particularly acute point; inferior appendage slightly less than 1/3 the length of superiors, with lateral edges of basal portion convex and rather abruptly narrowing into a very slightly tapered and rather long apical portion.

Distinguished from G. dobsoni , with which it overlaps in range in Australia, by (1) fewer denticles (3–10) along genital fossa that are generally restricted to the posterior part, (2) more distinctly sinuous and less sharply pointed superior anal appendages and (3) by the longer, more slightly tapered apical portion of the longer inferior appendage.

Distinguished from G. amphora by (1) only 2, very rarely 3, rows of cells between anal triangle and anal loop in Hw, (2) by lack of a pale mid-dorsal pattern element in S2 and (3) by the much slimmer posterior part of S3.
