Odontoperla gen. nov.

Type species: Dinotoperla schneiderae Theischinger, 1982 . Mem. Qd. Mus. 20: 504.

Generic description. Adult: Forewing with Rs simple and CuA forked; more than 1 distal crossvein in each space between R1 and CuA. Hindwing with MP and CuA fused for a part. Male tergite X with anterior and lateral sclerites and without posterior sclerite. Central sclerite of tergite X produced into a substantial membranous cone; epiproct with dorsal teeth and apical ventral spur; paraprocts with subapical thickening followed by a constriction. Diagnostic characters for the adult male are the dorsal dentition of the epiproct and the subapical thickening followed by a constriction of the paraprocts.

Larva. Cerci longer than body with thin elongated segments. Paraprocts triangular with a rounded tip, length of paraproct is less than basal width. Robust body with sturdy legs. Frons covering the clypeus. Pronotum not extending past width of head. No femoral spur present. Distinguishing characters of larvae are the short triangular paraprocts; pronotum not extending laterally past eyes; unicolour appearance with dorsal surface covered by dark long robust setae tapering to a point.

Remarks. This complex is distributed across a large area from north-eastern NSW to north Queensland . However, only two adult males were collected one from Bunya Mountains and one from Tully Gorge with both considered to be D. schneiderae . Genetic samples showed a high level of divergence between the specimens and geographic clades were identified. This species is considered a complex as larval morphology also showed no characters to distinguish between the clades. Additionally, based on the adult male morphology D. spinosa is also considered to belong to this genus. Specimens are deposited in ANIC

Etymology. From the Greek odonto meaning teeth referring to the dentitions on the epiproct of the adult male.
