A large portion of the amphibian species occurring in Amazonia remains undescribed. A recent study on species delineation in Anomaloglossus, a genus endemic to the Guiana Shield, demonstrated the existence of two undescribed species previously identified as A. degranvillei, which we describe herein. In addition to divergence at the molecular level, these two new taxa are also distinguished by subtle morphological characters and substantial differences in the advertisement calls (note length, dominant frequency, note structure). One species occurs in the hilly lowlands of north-eastern French Guiana and is mainly distinguished from its closest relatives by a small body size (15.9–18.8 mm in males) and by vocalisations characterized by the emission of short notes of 0.09 s on average. The other species is only known from the Itoupé Massif in southern French Guiana and is mainly distinguished from its closest relatives by a moderate body size (19.4–20.4 mm in males) and by vocalisations characterized by the emission of long notes of 0.23 s on average. We also provide amended definitions for two previously described species in the A. degranvillei species group: A. degranvillei, which is endemic to a few massifs in central French Guiana, and A. surinamensis, which is distributed throughout Suriname and French Guiana. The new species described here and A. degranvillei have very narrow ranges within French Guiana and seem to have rapidly declined during the last decade. Therefore, we suggest A. degranvillei and A. dewynteri to be considered as “Critically Endangered” and A. blanci as “Vulnerable” according to the IUCN standards.

A New Species

We describe a new Pristimantis from La Libertad and Rumiloma, Reserva Mazar, Andes of Southeastern Ecuador, at elevations between 2895–3415 m. This species is assigned to the P. orestes group, from whose members it differs by its small body size (adult males ≤ 18.1 mm; adult females ≤ 23.7 mm), usually reticulated ventral pattern, and visible tympanum. The vocalization of the new species consists of a series of calls; each call is composed by a pulsed, non-modulated note in frequency, and with a dominant frequency of 3122–3171 Hz. A molecular phylogeny based on a fragment of the mitochondrial gene 12S shows that the new species is sister to Pristimantis simonbolivari.

The taxonomy of the New World species of Polyplectropus (Ulmer, 1905a) is revised to include detailed male and female diagnoses, descriptions, illustrations, distribution records, and keys to males of all species and species groups. A phylogenetic analysis based on 59 morphological characters, 89 of 92 (97%) New World Polyplectropus species, and 2 outgroup taxa was inferred using parsimony and Bayesian methods, which resulted in minor topological differences. Conflicting estimates of relationship among and within most species groups led to a less resolved Bayesian tree (vs. parsimony tree) due to high variation in rates of change among characters and an overall low number of characters. A new classification for New World Polyplectropus is proposed with revised characterization of 10 recognized species groups, 6 newly established. Four species remain unassigned to species group. A key to genera of New World Polycentropodidae, including a redescription of Polyplectropus is provided. The homology of the male genitalia of Polyplectropus is discussed. Ninety-two species are treated. The following 39 new species are described: Polyplectropus adamsae (Peru), P. alatespinus (Brazil), P. amazonicus (Brazil), P. andinensis (Argentina, Bolivia), P. blahniki (Venezuela), P. bolivianus (Bolivia), P. brasilensis (Brazil), P. brborichorum (Ecuador), P. cressae (Venezuela), P. colombianus (Colombia), P. corniculatus (Peru), P. cuzcoensis (Peru), P. ecuadoriensis (Ecuador), P. flintorum (Venezuela), P. gaesum (Brazil), P. guyanae (Guyana, Venezuela), P. hollyae (Brazil), P. hystricosus (Brazil), P. insularis (Panama), P. juliae (Brazil), P. kanukarum (Guyana), P. maculatus (Venezuela), P. manuensis (Peru), P. matatlanticus (Brazil), P. minensium (Brazil), P. novafriburgensis (Brazil), P. peruvianus (Peru), P. petrae (Brazil), P. pratherae (Brazil), P. puyoensis (Ecuador), P. robertsonae (Bolivia), P. rodmani (Brazil), P. rondoniensis (Brazil), P. tragularius (Brazil), P. tripunctatum (Peru), P. venezolanus (Venezuela), P. woldai (Panama), P. zamoranoensis (Honduras), and P. zuliae (Venezuela). Polyplectropus buchwaldi (Ulmer, 1911) is designated as a nomen dubium.Key words: phylogeny, taxonomy, Neotropics, Nearctric, Bayesian methods, parsimony, classification, cladistics, morphology, Trichoptera, Polycentropodidae, Polyplectropus, new speciesThe polycentropodid caddisfly genus Polyplectropus Ulmer contains 219 species found primarily in the tropical and subtropical regions of the world, with 125 species recorded from the Oriental biogeographic region, 53 from the Neotropical region (6 species extending their ranges into the Nearctic region), 37 from the

We describe a new species of fan-throated lizard of the genus Sitana from the Deccan peninsula of India. The new species is from the Sitana sivalensis clade and can be readily diagnosed morphologically from S. sivalensis, S. fusca and S. schleichi by having the dewlap extending beyond forearm insertion. The new species differs from all other congeners in the combination of morphological characters such as a feebly serrated dewlap with a dark blue line on the throat in adult males (versus  a well serrated dewlap with a bright blue patch and orange spots in S. ponticeriana complex), small body size (versus a large body size in S. gokakensis and S. thondalu) and a relatively smaller dewlap size (relatively larger in S. laticeps, S. spinaecephalus, S. dharwarensis, S. gokakensis, S. thondalu, S. marudhamneydhal, S. ponticeriana and S. visiri). The new species was found to be commonly distributed in arid and open habitats as well as in farmlands and plantations in northern Andhra Pradesh, eastern Madhya Pradesh and most parts of Chhattisgarh and Odisha states.

A New Species

Treefrogs of the genus Boophis comprise the most species-rich genus among all Malagasy frogs. In this paper we describe a new species to be added to this genus from Masoala Peninsula and nearby areas. Related populations have been found in three localities of North-Eastern Madagascar (Tsararano, Marojejy, and Anjanaharibe-Sud), and molecular data indicate that at least the Marojejy population is strongly differentiated. The new species has an attractive pink or reddish colour pattern on a green ground colour. It bears a strong similarity to Boophis bottae and B. rappiodes in morphological appearance, but is genetically very distinct from these and other members of the Boophis rappiodes group. Boophis ulftunni sp. n. belongs into a separate evolutionary lineage probably related to the Boophis microtympanum group, a lineage of highland species from Central Eastern Madagascar which otherwise have very different phenotypes and advertisement calls. We here include B. ulftunni in a new phenetic species group, the Boophis ulftunni group.

A new species of the genus Cnemaspis Strauch, 1887 is described from the Rajgad fort in the northern Western Ghats of Maharashtra, India. The new species, belonging to the flaviventralis clade, is one of the smallest known Indian Cnemaspis and can be distinguished from other congeners by its genetic distinctiveness and few key morphological characters. The new species can be diagnosed from all other Indian congeners by its small body size (SVL < 27 mm), the absence of conical and spine-like tubercles on flank; heterogeneous dorsal pholidosis; presence of only femoral pores and no precloacal pores in males; weakly keeled scales on the ventral surface of neck, pectoral, abdominal region and limbs; granular scales on the tail with whorls of slightly enlarged, strongly keeled tubercles; and the absence of enlarged median subcaudal scales. The new species is currently known to inhabit the man-made historical structures from a single locality in Rajgad, Maharashtra, where it is presumed to be uncommon.

Continuous sampling in well studied areas may lead to new amphibian species discoveries, because population dynamics allow rare species to go unnoticed for years. Based on recent sampling of frogs in the northeastern region of Colombia, here we provide genetic, morphological, and bioacoustics evidence to support the description of a new species of the genus Pristimantis. Phylogenetic analysis suggests the new species is a member of the P. lacrimosus species group, a clade of 25 species that is highly diverse in Ecuador and Peru. This new species is more closely related to allopatric species from Peru and Guyana (i.e. P. olivaceus, P. pluvialis, P. pulchridormientes, and an undetermined Pristimantis). The new species has green-yellow coloration and a remarkable brown interocular band, which is unusual in the genus and which inspired the epithet. Pristimantis zorro sp. nov. has only been found at one locality at 1860 m s.a.l., on the eastern flank of the northern Cordillera Central in Department of Antioquia, Colombia. The new species inhabits the ecotone between the humid cloud forest and open areas. Repeated visits to the type locality suggest high variation in population abundance and/or species detection, because we have occasionally observed many individuals in briefs periods of times. In addition, we discuss the biogeographical and systematic implications of our species discovery.
