We provide details of its morphology, calls, embryos and tadpoles, and phylogenetic relationships to other species of eastern Uperoleia. We also provide the results of targeted surveys to establish its distribution and provide observations of its habitat associations. As a consequence of these surveys, we comment on the likely restricted nature of the species' distribution and habitat, and place this in the context of a preliminary assessment of its putative conservation status, which should be assessed for listing under the IUCN's red list. We note this species, which is morphologically distinct, has gone unnoticed for many decades despite numerous eco-logical surveys for local development applications.]]> Wed 11 Apr 2018 12:58:44 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48224 Tue 21 Mar 2023 16:28:00 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:40838 Tue 19 Jul 2022 10:54:27 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:50998 Tue 15 Aug 2023 11:46:04 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51621 Tue 12 Sep 2023 14:24:10 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:42941 Thu 08 Sep 2022 12:23:21 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:11390 Sat 24 Mar 2018 08:09:59 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:18968 Sat 24 Mar 2018 07:58:53 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:17728 Sat 24 Mar 2018 07:57:45 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:26377 Pethia melanomaculata (Deraniyagala) is available for the Sri Lankan fish previously referred to P. ticto, being distinguished from its Indian congeners by the combination of the following characters; having 1/2 4/1/3 1/2 scales in transverse line on body; body depth 32.4-41.5% of standard length (SL); head length (HL) 26.1-29.2% of SL; snout length 25.3-35.6% of HL; eye diameter 24.4-31.9% of HL; a small black humeral spot on lateral-line scales 3 or 4; a black spot on caudal peduncle, on scales 16-18 of the lateral line series; 3 unbranched dorsal-fin rays, the last one strongly serrated, with 8-11 serrae.]]> Sat 24 Mar 2018 07:33:06 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:29739 Sat 24 Mar 2018 07:27:42 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30172 Cyclorana platycephala, occurs in the Australian arid and semi-arid zones but not in the central Australian deserts. Recent inspection of morphological variation in adults and larvae suggests that the taxon comprises three regional populations: eastern, northern and western that may each represent separate species. To assess the systematic status of these populations, we documented phylogenetic relationships using mitochondrial and nuclear DNA markers, divergence in adult and larval morphology and male advertisement call. Our molecular genetic data demonstrates that the western population of C. platycephala is not the sister taxon of eastern and northern representatives of this nominate species, as the latter two are more closely related to another morphologically distinct species, C. verrucosa. Discriminant Function Analysis of 14 morphological traits in adults and 15 in larvae showed a high degree of morphological differentiation of western versus eastern/northern C. platycephala. Calls of eastern and western populations differed in duration, pulse rate, frequency and especially in amplitude modulation pattern across the call duration. We describe the western population as a new species, whose range is contained entirely within Western Australia. In addition, we redescribe Cyclorana platycephala, quantify morphological and genetic differences between the eastern and northern populations, and conclude that these data support recognition of a single species, Cyclorana platycephala, for populations found in New South Wales, the Barkly Tablelands and south-eastern Northern Territory, Queensland and South Australia.]]> Sat 24 Mar 2018 07:26:16 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:23565 Sat 24 Mar 2018 07:14:09 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51793 91% of individuals being correctly classified in DFA. The two lineages differ in the number and size of spots on the lateral surfaces and the degree by which the cloaca is surrounded by colour patches. The mating calls are significantly different in number of pulses in the note. The presence of a F2 hybrid in the area where the distribution of the two taxa come into closest proximity leads us to assign subspecies status to the lineages, as we have not been able to assess the extent of potential genetic introgression. In our sampling, the F2 hybrid sample sits within an otherwise unsampled gap of ~90km between the distributions of the two lineages. The nominate northern sub-species is restricted to the Sydney Basin bioregion, while the newly recognised southern subspecies occurs from south of the Kangaroo Valley in the mid-southern coast of New South Wales to near Walhalla in central Gippsland in Victoria. The habitat of the two subspecies is remarkably similar. Adults spend large portions of their lives on the forest floor where they forage and burrow in a variety of vegetation communities. The southern subspecies occurs most commonly in dry sclerophyll forests with an open understory in the south and in open forest and heath communities with a dense understory in the north of its distribution. The northern subspecies is also found in dry open forests and heaths in association with eroded sandstone landscapes in the Sydney Basin bioregion. Males of both taxa call from both constructed burrows and open positions on small streams, differing from the five Western Australian species of Heleioporus where males call only from constructed burrows. Using the IUCN Red List process, we found that the extent of occupancy and area of occupancy along with evidence of decline for both subspecies are consistent with the criteria for Endangered (A2(c)B2(a)(b)).]]> Mon 18 Sep 2023 15:17:58 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51693 Fri 15 Sep 2023 09:42:58 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:42959 Fri 09 Sep 2022 08:34:21 AEST ]]>
