Gyrocochlea Hedley, 1924: 215 (in part); Iredale 1937: 322 (in part); Iredale 1941a: 267 (in part); Smith 1992: 190 (in part); Stanisic et al . 2010: 196 (in part). Type species. Comboynea boorganna n. sp. —here designated. Etymology. For the Comboyne Plateau. Diagnosis. Shell very small, orange brown, biconcave or discoidal/planate with tightly coiled whorls, the last inflated. Protoconch sculpture primarily spiral with numerous, prominent, low crowded spiral cords and extremely weak, irregularly spaced, underlying radial ridges; teleoconch with many sinuate radial ribs; microsculpture cancellate consisting of prominent microradial ribs and low microspiral cords, beaded at their intersection. Aperture narrowly to broadly ovately-lunate. Umbilicus wide U-shaped to wide cup-shaped. Penis tubular with an apical verge that has a lateral pore; longitudinal ridge-shaped pilasters present. Epiphallus shorter than penis. Distribution and habitat. From the Port Stephens area northward to the Manning River drainage basin, NSW; found in rainforest on volcanics, living under logs and rocks. Remarks. Comboynea gen nov . is distinguished from Barringtonica by the combination of protoconch sculpture and penial anatomy. In Comboynea the penis has a verge, and the protoconch sculpture weakly cancellate, consisting of broad spiral cords and very weak underlying radial ridges throughout; in Barringtonica the verge is absent and the protoconch sculpture is chiefly spiral, with radial ridges that develop only toward the protoconch/teleoconch boundary.
