越南中部发现棱皮树蛙属一新种（两栖纲：树蛙科）

Abstract

A new species of small tree frog from a primary montane tropical forest of central Vietnam, Tay Nguyen Plateau, is described based on morphological, molecular, and acoustic evidence. The Golden Bug-Eyed Frog, Theloderma auratum sp. nov., is distinguishable from its congeners and other small rhacophorid species based on a combination of the following morphological attributes: (1) bony ridges on head absent; (2) smooth skin completely lacking calcified warts or asperities; (3) pointed elongated tapering snout; (4) vocal opening in males absent; (5) vomerine teeth absent; (6) males of small body size (SVL 21.8–26.4 mm); (7) head longer than wide; ED/SVL ratio 13%–15%; ESL/SVL ratio 16%–20%; (8) small tympanum (TD/EL ratio 50%–60%) with few tiny tubercles; (9) supratympanic fold absent; (10) ventral surfaces completely smooth; (11) webbing between fingers absent; (12) outer and inner metacarpal tubercles present, supernumerary metacarpal tubercle single, medial, oval in shape; (13) toes half-webbed: I 2–2¼ II 1½–2¾ III 2–3¼ IV 3–1½ V; (14) inner metatarsal tubercle present, oval; outer metatarsal tubercle absent; (15) iris bicolored; (16) dorsal surfaces golden-yellow with sparse golden-orange speckling or reticulations and few small dark-brown spots; (17) lateral sides of head and body with wide dark reddish-brown to black lateral stripes, clearly separated from lighter dorsal coloration by straight contrasting edge; (18) ventral surfaces of body, throat, and chest greyish-blue with indistinct brown confluent blotches; (19) upper eyelids with few (3–5) very small flat reddish superciliary tubercles; (20) limbs dorsally reddish-brown, ventrally brown with small bluish-white speckles. The new species is also distinct from all congeners in 12S rRNA to 16S rRNA mitochondrial DNA fragment sequences (uncorrected genetic distance P>8.9%). Advertisement call and tadpole morphology of the new species are described. Our molecular data showed Theloderma auratum sp. nov. to be a sister species of Th. palliatum from Langbian Plateau in southern Vietnam.

Integrated phylogenetic analyses reveal the evolutionary, biogeographic, and diversification history of Asian warty treefrog genus Theloderma (Anura, Rhacophoridae)

“…Based on previous phylogenies, Theloderma was composed of subgenera Stelladerma and Theloderma, and seven species groups: T. horridum group, T. moloch group, T. asperum group, T. leporosum group, T. lateriticum group, T. laeve group, and T. corticale group (Kurniawan et al, 2023;Poyarkov et al, 2018) (Table S10). Using combined mitochondrial and nuclear gene data, we recovered three well-supported clades within Theloderma that were similar to those delineated in previous revisions (Figure 3): Clade A and Clades B + C corresponded to the subgenera Stelladerma and Theloderma.…”

“…The Asian warty treefrog, genus Theloderma (Anura, Rhacophoridae), is endemic to Southeast Asia, South Asia, and Southern China and currently containing 29 species (Figure 1) (Frost, 2023). Previous phylogenetic studies have supported Theloderma as a sister clade to Nyctixalus (Chan et al, 2018(Chan et al, , 2020Chen et al, 2020;Poyarkov et al, 2018), and it can be further divided into two subgenera (Stelladerma and Theloderma) and six species groups, that is, T. leporosum group, T. leave group, T. lateriticum group, T. corticale group, T. moloch group, and T. asperum group (Poyarkov et al, 2015). According to several biogeographic studies, the genus formed in the Middle Oligocene (Li et al, 2013)/Late Eocene (Ellepola et al, 2022)/Early Miocene (Chen et al, 2020) by the dispersal of the ancestor of Nyctixalus through the Sundaland.…”

Amphibians and reptiles from Lawachara National Park in Bangladesh

“…This treefrog is easily differentiated from other regional frogs by its characteristic brown, tan, and white mottled coloration, reminiscent of tree fungus or bird droppings (Ahmed et al 2009). With its webbed toes, reddish eyes, cream-colored body with distinct brown markings on the top of head and back, dark brown legs with black and cream banding, and dark marbling on venter, the frogs appear morphologically identical to T. pyaukkya Dever, 2017 in Myanmar, which is now being subsumed under T. baibungense (Dever 2017, Poyarkov et al 2018Nikolay Poyarkov pers. comm.).…”

“…Taxonomic notes. Though south Asian frogs of this species complex were previously identified as T. asperum (Boulenger, 1886) or T. albopunctatus (Liu and Hu, 1962), genetic evidence has shown that Northeast Indian and central/northern Burmese members of the group are T. baibungense (Hou et al 2017;Poyarkov et al 2018; Nikolay Poyarkov pers. comm.).…”
