A New Species

We describe Engystomops puyango sp. nov. from the lowlands of southwestern Ecuador. The new species is closely related to E. pustulatus from which it differs in skin texture, advertisement call, and karyotype features. The new species also differs from E. pustulatus at genes 12S and 16S of mitochondrial DNA (6.5%–6.8% of sequence divergence). A phylogeny based on mtDNA shows that E. sp. nov. is part of a clade of Engystomops distributed below 1300 m in western Ecuador and northwestern Peru. The new species occurs in Evergreen Lower Montane Forest and Foothill Semideciduous Costa Forest. The karyotype of the new species has 2n = 20 chromosomes which represents the first known reduction in chromosome number in Leiuperidae (2n = 22). Its advertisement calls as well as those of E. pustulatus have a facultative component that resembles the chuck in calls of E. pustulosus but that are less discrete and have lower acoustic complexity.

A New Species

We describe a new species of Bryophryne from the Cordillera de Vilcabamba in Department Cusco, in the southeastern Peruvian Andes. The new species differs from all other congeneric taxa, except B. flammiventris and B. gymnotis, by possessing a weakly defined tympanic membrane and tympanic annulus, by the presence of vocal sac and vocal slits in males, and by producing advertisement calls. The new species is distinguished from B. flammiventris and B. gymnotis by skin texture, presence of small, oblique dentigerous processes on the vomer, ventral coloration ranging from bluish-gray to whitish-gray with irregular or reticulate dark brown spots, and call composed of two or three notes. The new species is further characterized by having dorsal skin shagreen with tubercles, discontinuous dorsolateral folds, skin smooth on ventral surfaces of the body, and lateral fringes on fingers and toes. This species was found at the transition from montane forest to high Andean puna, where it occurs in moist microhabitats under moss and rocks at elevations from 3519 to 3707 m a.s.l.

Sinosenecio ovatifolius (Asteraceae, Senecioneae), a new species occurring in northeastern Guangxi, China, is illustrated and de-scribed with report on its floral micromorphological characters, achene surface feature and chromosome number. The new spe-cies is phylogenetically close to S. guangxiensis, S. jiangxiensis, S. jiuhuashanicus, S. latouchei, S. peltatus, S. saxatilis, and S. wuyiensis. Morphology and sequence divergence of the nrITS region indicate that S. ovatifolius is well differentiated from its close relatives. It most closely resembles S. guangxiensis and S. latouchei in the scapigerous habit, leaf texture and indumentum, but differs markedly in the ovate lamina, inconspicuously undulate-dentate margin and glabrous and smooth achene surface.

Nurse frogs (Aromobatidae: Allobates) are probably the most extensively studied genus by taxonomists in Brazilian Amazonia. The southwestern portion of Amazonia is the most species-rich: as many as seven species may occur in sympatry at a single locality. In this study, we describe a new species of nurse frog from this region. The description integrates data from larval and adult morphology, advertisement calls and DNA sequences. Allobates velocicantus sp. nov. is distinguished from other Allobates mainly by the absence of hourglass-shaped dark marks on the dorsum and dark transverse bars on the thigh; a throat that is white centrally and yellow marginally; basal webbing on toes II and III; finger I longer than finger II; and an advertisement call composed of 66–138 pulsed notes with a note duration of 5–13 ms, inter-note intervals of 10–18 ms and a dominant frequency of 5,512–6,158 Hz. Tadpoles of the new species have 3–4 short, rounded papillae on the anterior labium, 16–23 papillae on the posterior labium, and a labial keratodont row formula 2(2)/3(1). This is the fifth species of Allobates described from the state of Acre, southwestern Brazilian Amazonia.

A New Species

We describe a new species of megophryid frog in the genus Leptolalax from the Kon Tum Plateau in northeastern Cambodia. Leptolalax melicus sp. nov. is distinguished from its congeners by a combination of an off-white to pale pink ventral surface with diffuse dark brown blotches and distinct white speckling, finger I < II, an absence of webbing and dermal fringes on fingers, slight basal webbing and no dermal fringes on toes, body size (19.5–22.7 mm for seven adult males), an absence of ventrolateral glandular lines, dorsum mostly smooth with no skin ridges, and a unique advertisement call consisting of a single long introductory note containing 8–50 pulses, followed by 3–11 predominantly single-pulsed notes, and with an average dominant frequency of 3560–3610 Hz. Leptolalax melicus can be further distinguished from the morphologically similar L. applebyi in having more distinct dorsal patterning, and significantly larger pectoral and femoral glands. Leptolalax melicus and L. applebyi also differ by 6.1% sequence divergence at the 16S mtDNA gene. All specimens of L. melicus were found near rocky streams in evergreen forest between 650–850 m elevation. We suggest the new species should be considered Data Deficient following IUCN’s Red List categories.

We describe a new species of the Bokermannohyla circumdata group from the Estação de Pesquisa e Desenvolvimento Ambi-ental Galheiro (EPDA-Galheiro) (19o 12′S; 47o 08′W), Municipality of Perdizes, State of Minas Gerais, a mid-altitudinal (~ 850m above sea level) riparian forest environment in the Cerrado of southeastern Brazil. Bokermannohyla napolii sp. nov. is alliedto the large-sized species of the group, diagnosed on the basis of adult morphology/morphometrics, and mainly vocalizations.Adult specimens of the new species are most closely related to those of B. luctuosa and B. circumdata, but can be differentiatedfrom the former by having distal subarticular tubercle of finger III bifid/divided in males, and finger IV bifid/divided in malesand females; and from both B. luctuosa and B. circumdata by a distinctive advertisement call structure. We also provide bioa-coustic data on seven other species of the genus, including previously unknown advertisement calls of B. circumdata and B. carvalhoi, and re-description of the advertisement calls of B. luctuosa, B. ibitiguara, B. nanuzae, B. sazimai, and B. hylax.

Here we describe a new species of the toad genus Amazophrynella (Bufonidae) from the south margin of the Amazon River in Santarém, state of Pará, Brazilian Amazonia. The new species can be diagnosed by (1) medium body size for the genus: adult females 19.5–20.4 mm SVL, adult males 13.0–14.5 mm SVL; (2) snout acuminate in lateral view; (3) Finger I larger and robust; (4) Finger I nearly equal in size than Finger II; (5) palmar tubercle rounded, covering ¼ of hand; (6) pigmented callus in Finger I in males; in life: (7) brown stain on throat and chest; (8) black dots on venter. Males emit two distinct advertisement calls: the call type 1 consists of a relatively long note (mean 0.248 s) with a mean dominant frequency of 3526 Hz. The call type 2 is arranged in bouts of 6 to 22 notes with mean dominant frequency of 3450 Hz and much shorter note durations (mean 0.034 s). In this study we also redescribe the advertisement call of A. minuta, which also emits a second call type.

We describe a new species of Chiasmocleis (Anura: Microhylidae) from lowland rainforests in the western Amazon basin of Peru (near Iquitos, Departamento de Loreto). The species differs from congeners in the Amazon basin by its large size (it is the largest known Chiasmocleis species), bright yellow iris, a grey dorsum with reddish blotches posteriorly and on limbs, and a creamy white venter with bold dark mottling with pale centers. The new species also differs from two other sympatric Chiasmocleis species at 12S–16S mitochondrial DNA (6.1% and 11.9% sequence divergence between the new species and C. ventrimaculata and C. bassleri, respectively). A comparison of the new species with other microhylids found in the western Amazon basin is provided.

Taxonomic Approach

A new species in the dicroglossid frog genus Limnonectes is described from Ko Pha-ngan, Ko Samui, and Ko Lanta Yai Islands in southern Thailand. Males of Limnonectes pseudodoriae sp. nov. lack a caruncle on top of the head and very closely resemble L. doriae (Boulenger, 1887) from Myanmar and western and southern Thailand. However, the new species is distinguished from L. doriae and its congeners using an integrative taxonomic approach of morphology, mitochondrial DNA, and bioacoustics. Limnonectes pseudodoriae sp. nov. differs from L. doriae and its congeners by having a unique combination of morphological characters, including body size; skin texture of the interorbital region, dorsum, and shank; toe webbing; relative size of the inner metatarsal tubercle; and coloration of the tympanum, venter, and ova. The advertisement call of the new species is also readily differentiated from that of L. doriae in temporal parameters. Limnonectes pseudodoriae sp. nov. is highly divergent in mitochondrial DNA from L. doriae and its congeners, but its phylogenetic position within the genus is not resolved. The natural history of the new species is presented, and the geographic range of L. doriae in Thailand is clarified.
