Oxyethira (Trichoglene) bamaga sp. nov.

Figures 6, 7

Diagnosis. This species is a member of subgenus Trichoglene, and similar to O. columba (Neboiss) from southeastern Australia to mid Queensland, and O. triangulata Wells, from far northeastern Australia (but see below), in having short, sclerotised gonopods. However, in ventral view these are pillar-like, with length almost 3x width, compared with the much shorter, tapered structures in those two species.

Description. Male. Length of each forewing 1.6–1.9 mm (n = 2). Antennae each with 24–25 flagellomeres. Abdominal segment VII with small acute apico-medial spine on ventral surface. Genitalia as in Figs 6, 7. Segment VIII quadrate in ventral view. Segment IX triangular, deeply retracted into segment VIII, pair of triangular sclerotised processes laterally. Dorsal plate short, broad, with area of minute spinules apico-medially. Gonopods stout, sclerotised, in ventral view, length close to 3x width; dorsal process slender, positioned almost at right angle to length of body. Phallic apparatus about 1.5x length of abdominal segment VIII, without titillator; short membranous sheath subapically; apex bearing slender, twisted spine.

Female. Unknown.
