Abstract: Hyalotos Richards, Mahony & Donnellan, gen. nov. (Fig. 17) ZooBank LSID: urn:lsid:zoobank.org:act: 7C1C360B-D81D-4985-A93C-D065C201ED 53 Type species: Litoria richardsi Dennis & Cunningham, 2006. Content: Three species— Hyalotos naispela * (Richards, Donnellan & Oliver, 2023) comb. nov., Hyalotos richardsi * (Dennis & Cunningham, 2006) comb.nov., Hyalotos singadanae * (Richards, 2005) comb. nov. Diagnosis: Hyalotos can be diagnosed from other pelodryadids by a combination of a wholly or substantially transparent tympanum, crenulated ornamentation of the hindlimb, and medium to large, pigmented eggs, high dominant call frequency, absence of call frequency modulation, tear drop call envelope shape, none vs. a note rate change across the call. Refer to Tables 1 and 2. Distribution and ecology: New Guinea lowlands to lower montane species. Arboreal frogs known or expected to lay eggs on tree trunks over tree-holes (Richards et al. 2023). Etymology: From the Greek ὕαΛος (hyalos, glass) and Ωτός (otos, ear), alluding to the transparent tympanum. The name, based on otos, is neuter. Remarks: The tympanum is predominantly transparent, a character unique among pelodryadids (Richards 2005, Denis and Cunningham 2006, Richards et al. 2023).
