A new species of the miniaturised microhylid frog genus Stumpffia, from north-western Madagascar, is described. Stumpffia froschauerisp. nov. differs from all other described Stumpffia species in colouration and morphology and is genetically divergent (≥ 7% uncorrected p-distance to all other nominal species of the genus) in a fragment of the mitochondrial 16S rRNA gene and in a segment of the nuclear Rag-1 gene. The new species is reliably known only from a few specimens collected in the Sahamalaza (and surroundings) region. Its known distribution is limited to three forest patches severely threatened by fire, drought and high levels of forest clearance, thus suggesting a classification of “Critically Endangered” according to IUCN Red List criteria.

We describe a new species of arboreal narrow-mouthed frog, genus Platypelis, from Ambodivoangy near Maroantsetra in northeastern Madagascar. The new species, Platypelisandosp. nov., is characterised by small body size (under 19 mm), a generally rather slender body, yellowish finger and toe tips, and a dark brown dorsal chevron. Its advertisement call is a single, moderately long, high-pitched whistle repeated at regular intervals. It is the sister species of P.ravus from Marojejy National Park, but differs from that species by considerable pairwise genetic distances (7.9%) in a fragment of the mitochondrial 16S rRNA gene, and also in bioacoustic and morphological features, especially the absence of yellow on the posterior abdomen. It is also surprisingly similar in external appearance to Cophylaoccultans and C.maharipeo, to which it is not, however, closely related; these species are most easily discerned based on their calls. Platypelisandosp. nov. joins the ranks of several species recently described from Ambodivoangy with close affiliations to species in the nearby Marojejy National Park, that are still divergent at species level. The species qualifies as Critically Endangered according to the IUCN Red List criteria, in line with other species recently assessed from this area, but we urge that more research be conducted in the nearby forests to extend the range of this and other species known only from Ambodivoangy.

A New Species

We describe a new species of arboreal microhylid frog, genus Platypelis, from northeastern Madagascar and report the expansion of distribution ranges of two other species. Platypelis laetussp. nov. is small to medium-sized (24.3–25.6 mm snout-vent length) compared to other Platypelis, exhibits a greenish colored throat and was found in bamboo forest of the Sorata Massif. Its advertisement call consists of a single short tonal note repeated at regular intervals in long call series. Based on DNA sequences of a fragment of the mitochondrial 16S rRNA gene, the new species was placed in a clade with Platypelis olgae from the Tsaratanana Massif, and with two other, unconfirmed candidate species from the Sorata Massif and from Andravory, herein named Platypelis sp. Ca12 and Ca13. Molecular divergences among these lineages were substantial, amounting to 7.6‒8.1% uncorrected 16S p-distance to the closest nominal species, P. olgae, from which the new species is also distinguished by a lack of allele sharing in the nuclear RAG-1 gene. We also provide new records of Platypelis alticola and P. tsaratananaensis from the Sorata Massif, supported by molecular analysis. This confirms a wider distribution of these two species that previously were considered to be endemic to the Tsaratanana Massif. However, their populations in Sorata were characterized by a certain degree of genetic differentiation from Tsaratanana populations suggesting they require more detailed taxonomic assessment.

Two New Species

The northern part of Madagascar is well known for its high species diversity and endemism. Exceptional species richness is related to the existence of large forest blocks and mountain complexes. These areas shelter a diverse variety of habitats occupied by a wide diversity of species, including leaf-tailed geckos of the genus Uroplatus. Based on morphological and molecular evidence, we here formally name two evolutionary lineages as new species that previously had been considered as candidate species (Uroplatus spp. Ca3 and Ca4), both small-sized species of the Uroplatus ebenaui group. Genetically, both new species are related to U. finiavana with a genetic divergence (uncorrected pairwise distance) of 10.3–12.8% in a fragment of the mitochondrial 16S rRNA gene, and separated from each other by 10.3–10.7%. Uroplatus fangorn sp. nov. is described from the Marojejy massif and is also known from Andrevorevo, Lohanandroranga and Sorata; it is similar to U. ebenaui and U. fetsy but is distinguishable by its rather short tail and only partially black pigmented oral mucosa. Uroplatus fivehy sp. nov. is described from the Sorata Massif and is wider-ranging, occurring in an area from Marotandrano and Makira to Sorata, comprising Marojejy, Anjanaharibe-Sud, Ankitsika and Betaolana; it is morphologically similar to U. finiavana but distinguishable by tail size and shape. Both newly described species are found in rainforest from mid to high elevation and range respectively from 840–1417 m for U. fivehy sp nov. and 1300–1800 m for U. fangorn sp. nov. According to their respective geographical distributions, we propose to classify the two new species as Vulnerable under the IUCN Red List criteria, due to their occurrence in some forests outside of the protected area network plus the continuing decline of forest patches in the north of Madagascar.

A New Species

We describe a new species of poison frog from the Serranías de Santiago and Chochis, isolated Precambrian sandstone massifs in the Chiquitanía region of Bolivia. The new species is morphologically similar to the Brazilian Ameerega braccata and A. flavopicta and best distinguished by larger adult size (27.57 mm versus < 22 mm in A. braccata) and coloration of ventral surfaces in life (light grey to light brown with black marbling versus yellowish white with occasional black marbling in A. flavopicta), respectively. The new species is genetically most closely related to A. flavopicta (uncorrected p-distances of the 16S mitochondrial rRNA gene ca. 2 %) but clearly differs in characteristics of its advertisement call (longer note duration, lower note repetition rate, lower number of pulses per note, and lower fundamental and dominant frequency). The new species can be commonly found in the vicinity of rocks, often near running water, and should be considered 'Least Concern' (LC) under IUCN Red List criteria.

Abstract—We describe and illustrate Paepalanthus fabianeae, a new species of Eriocaulaceae from the central portion of the Espinhaço Range in Minas Gerais, Brazil. Previous phylogenetic evidence based on analyses of nuclear (ITS and ETS) and plastid (trnL-trnF and psba-trnH) sequences revealed P. fabianeae as belonging to a strongly supported and morphologically coherent clade containing five other species, all of them microendemic, restricted to the Espinhaço range. Due to the infrageneric classification of Paepalanthus being highly artificial, we preferred not assigning P. fabianeae to any infrageneric group. Paepalanthus fabianeae is known from two populations growing in campos rupestres (highland rocky fields) in the meridional Espinhaço Range. The species is characterized by pseudodichotomously branched stems, small, linear, recurved, and reflexed leaves, urceolate capitula, and bifid stigmas. Illustrations, photos, the phylogenetic position, and a detailed description, as well as comments on habitat, morphology, and affinities with similar species are provided. The restricted area of occurrence allied with threats to the quality of the habitat, mainly due to quartzite mining, justifies the preliminary classification of the new species in the Critically Endangered (CR) category using the guidelines and criteria of the IUCN Red List.

A new cryptic lineage of bush frogs of the genus Raorchestes from the understudied Eastern Ghats of India is described. Molecular phylogenetic reconstructions using mitochondrial 16S rRNA gene sequences suggest that the new species belongs to the Raorchestes charius clade, is sister to the allopatric R. charius of the Western Ghats and support the species-level distinctiveness of the lineage. The new species morphologically resembles R. charius from which it can be distinguished using the following characters: narrower head (HW/SVL 0.31 vs 0.34–0.36), wider inter upper eyelid (IUE/SVL 0.14–0.16 vs 0.11–0.13), greater maximum upper eyelid width (UEW/SVL 0.10–0.12 vs 0.06–0.09) and shorter thigh (TL/SVL 0.32–0.43 vs 0.44–0.51). Acoustic observations from the breeding males further corroborate the distinct specific status of the new species. The discovery of this new species of bush frog from an understudied landscape suggests that additional extensive surveys in the Eastern Ghats would yield several more amphibian lineages yet unknown to science.

AbstractThe type material of most European nominal species previously placed in Rhoptromeris and of some other species is studied. Notes are given on the type material, 10 lectotypes are designated and the identity of the species is discussed. Three valid Rhoptromeris species are found: R. heptoma (Hartig) [type species], R. villosa (Hartig) and R. rufiventris (Giraud) n.comb. The latter is the type species of Hexamerocera Kieffer which is synonymized with Rhoptromeris. The genus Rhoptromeris is described and compared with related genera. The three species found to be valid are figured and redescribed, and also a new species, R. nigriventris, is described from Sweden. R. heptoma is an important parasitoid of Oscinella frit (L.) (Dipt.: Chloropidae).

A new species of indotyphlid caecilian amphibian, Hypogeophis montanus sp. nov., is described based on a series of specimens from the Seychelles island of Mahé, collected from two localities in 2013 and 2015. The new species most closely resembles the Seychelles (Mahé) endemic H. brevis in being short (maximum known total length in life ca. 110 mm) and long snouted, but differs by having more vertebrae, a relatively smaller head, and substantially distinct mitochondrial and nuclear gene sequences. Hypogeophis montanus sp. nov. is known from higher elevations (718–731 m) than H. brevis (ca. 350–650 m), and its elevationally restricted distribution on a single small island likely renders it threatened under IUCN Red List criteria. Hypogeophis montanus sp. nov. is the third species of small and long-snouted caecilian reported from the Seychelles. Along with H. brevis and H. pti, H. montanus sp. nov. is among the smallest known species of caecilian and possibly has the smallest global distribution.

Begonia tinuyopensis is described and illustrated as a new species from Zamboanga del Norte, Philippines. This new species resembles B. mearnsii by having a decumbent stem, scattered hairs over the entire plant, terminal inflorescence bearing 2 staminate tepals and 5 pistillate tepals. However, Begonia tinuyopensis is distinct by having sparse pilose (vs. matted with long brown hairs) stems, ovate (vs. suborbicular to subreniform) leaves and glabrous (vs. densely pubescent) ovary. We assign B. tinuyopensis as Endangered (EN) following IUCN Red List Criteria.
