Abstract: Rhyaconastes Mahony, Donnellan & Richards, gen. nov. (Fig. 31) ZooBank LSID: urn:lsid:zoobank.org:act: 82FC7DE1-19E8- 4EB4-B16C-A27134640EA8 Synonymy Euscelis Fitzinger 1843: 31 (type species lesueurii). Unavailable as its preoccupied by Euscelis Brullé 1832: 109. Type species: Hyla lesueurii Duméril & Bibron 1841. Content: Four species— Rhyaconastes booroolongensis * (Moore, 1961) comb. nov., Rhyaconastes jungguy * (Donnellan & Mahony, 2004) comb. nov., Rhyaconastes lesueurii * (Duméril & Bibron, 1841) comb. nov., Rhyaconastes wilcoxii * (Günther, 1864) comb. nov. Diagnosis: Rhyaconastes can be diagnosed from Melvillihyla by its medium to large vs. very large body size, cartilaginous vs. ossified intercalary structures, tadpole oral disc Type 3 vs. Type 1, and overall tadpole morphology Type 6 vs. Type 5, and multiple vs. single notes per reproductive call. Refer to Tables 1 and 2. Distribution and ecology: Terrestrial frogs that breed in streams and rivers in forests and woodlands in eastern Australia. All species lack a vocal sac but produce a low amplitude call. Etymology: From the Greek ῥύακος (rhyakos, a stream or torrent) and ναστής (nastes, inhabitant), alluding to the stream-breeding habits of the species in the genus. The name, based on nastes, is masculine. 68 • Donnellan et al. Remarks: Rhyaconastes is the equivalent of the Litoria booroolongensis and L. lesueurii Groups of Tyler and Davies (1978). All Rhyaconastes species lack a vocal sac which distinguishes them from other ground-dwelling genera such as Cyclorana and Litoria.
