( Fig. 11)

ZooBank LSID: urn:lsid:zoobank.org:act:395E8CA0-986F-4F81-913B-3239EBB0B7DE Type species: Hyla gracilenta Peters, 1869 .

Content: 12 species— Chlorohyla aruensis ( Horst, 1883) comb. nov., Chlorohyla auae * ( Menzies & Tyler, 2004) comb. nov., Chlorohyla bella * ( McDonald, Rowley, Richards & Frankham, 2016) comb. nov., Chlorohyla callista ( Kraus, 2013b) comb. nov., Chlorohyla chloris * ( Boulenger, 1892) comb. nov., Chlorohyla elkeae *( Günther&Richards,2000) comb.nov., Chlorohylaeschata ( Kraus and Allison, 2009) comb. nov., Chlorohyla gracilenta * (Peters, 1869) comb. nov., Chlorohyla kumae ( Menzies & Tyler, 2004) comb. nov., Chlorohyla robinsonae ( Oliver, Stuart-Fox & Richards, 2008) comb. nov., Chlorohyla vagabunda ( Peters & Doria, 1878) comb. nov., Chlorohyla xanthomera * ( Davies, McDonald & Adams, 1986) comb. nov.

Diagnosis: Chlorohyla can be diagnosed from the sister taxon Pelodryas by overall tadpole morphology Type 4 vs. Type 1,

and by frequency modulated vs. non-modulated calls. Refer to Tables 1 and 2.

Distribution and ecology: Arboreal frogs that breed in ponds, found in forest and savannah habitats and modified landscapes in eastern Australia and New Guinea and surrounding islands.

Etymology: Refers to the bright green colour (Greek chlorós) of frogs (Greek Hyla ) in this lineage. The gender is feminine.

Remarks: Chlorohyla corresponds in part to the Litoria aruensis Group ( C. aruensis , C. chloris and C. gracilenta ) of Tyler and Davies (1978). We have conservatively placed Hyla vagabunda Peters & Doria, 1878 in Chlorohyla based on Menzies’ (2006) discussion of its affinities. Menzies (2006) suggested affinity with Litoria gracilenta based on a pale canthal stripe, but also indicated that the hands are unwebbed (S.J.R. observations also confirm reduced toe webbing), whereas Chlorohyla have finger webbing. It is known only from two specimens from Seram, Maluku Province, and Sorong, Southwest Papua Province, Indonesia. Tyler and Davies (1978) placed it in their monotypic Litoria vagabunda Group. A confident understanding of the affinities of H. vagabunda awaits the availability of further material. Five additional species lacking genetic data are included within Chlorohyla : C. aruensis , C. callista , C. eschata , C. kumae , and C. robinsonae . Hyla aruensis was considered a member of the Litoria gracilenta group by Menzies (2006). All of the others are moderately small green frogs with a pale canthal stripe that were assigned to the L. gracilenta group or considered related to that species in their original descriptions ( Menzies and Tyler 2004, Oliver et al. 2008, Kraus and Allison 2009, Kraus 2013b).
