New Localities

We provide information on the distribution, natural history, and conservation status of Nymphargus mixomaculatus (Guayasamin, Lehr, Rodriguez & Aguilar, 2006), a species from central Peru which is currently considered as Critically Endangered. We report four new localities and extend the altitudinal distribution by 430 m and the geographic range by 513 km in a straight line northwest of the previous, only known locality. Furthermore, based on our new data and following the criteria and categories of the International Union for Conservation of Nature, we suggest that N. mixomaculatus should be recategorized as Vulnerable.

A New Species

Angraecum jeannineanum, a new species endemic to Mauritius, is described and its ecology and conservation status are discussed. Angraecum jeannineanum differs from A. cadetii, which is the morphologically most closely related species, as follows: (i) leaves are smaller, thicker and darker green, (ii) inflorescences and flowers are thinner and smaller, (iii) flowers are more greenish and non-fleshy. Angraecum jeannineanum belongs to Angraecum section Hadrangis, endemic to the Mascarenes, which also includes A. bracteosum, A. cadetii and A. striatum. An updated key for the section is provided. The species should be considered as Critically Endangered (CR) according to the Red List Criteria of the International Union for the Conservation of Nature (IUCN). This assessment is based on the highly restricted species distribution, small population size, and habitat sustaining degradation by invasive alien plants and animals.

Taxonomic Studies

Pseudogonatodes furvus is an endemic gecko from the region of the Sierra Nevada de Santa Marta, an isolated massif located in the continental Caribbean region of Colombia. Pseudogonatodes furvus is the type species of the genus, and its morphology and natural history remain poorly known. This lizard was described based on two specimens. After its description, the species has only been mentioned in a handful of taxonomic studies of Pseudogonatodes, in which a few morphological characters of P. furvus have been mentioned. One other paper reported two new localities, without providing new information on the external morphology, especially the lepidosis of the newly obtained specimens. Here we review the external morphology of P. furvus, based on examination of the holotype and six additional specimens. We provide an extended diagnosis and definition, description of holotype, variation, comparisons with other Pseudogonatodes, geographic distribution (adding a fourth locality to the known distribution for the species), and conservation status. Additionally, we describe osteological features for the diagnosis of the genus.

The paper presents a catalogue of bird specimens (dry mounted preserves) survived after the closing (1948) of the former Catholic College “Saint Augustine”. Currently, the studied specimens are kept at the Regional Natural History Museum in Plovdiv. The collection includes a total of 193 species of birds of 81 families and 28 orders, represented by 205 specimens (circa two percent of the recent World avifauna). Over 15 percent of the species have an IUCN conservation status (NT to CR). The most valuable are the following specimens: critically endangered grey-backed myna (Acridotheres tricolor) and two endangered species - echo parakeet (Psittacula eques) and sooty albatross (Phoebetria fusca). This is the 2nd largest collection of exotic birds in Bulgaria.

Chloroplast Haplotype

Asplenium listeri C.Chr. has been considered endemic to Christmas Island and is one of only two fern species listed as Critically Endangered under Australia’s Environment Protection and Biodiversity Conservation Act. Its status as a distinct species has been questioned because of morphological similarity to the widespread A. polyodon G.Forst., which also occurs on Christmas Island. Molecular analyses revealed that A. listeri and plants attributed to A. polyodon from coastal limestone in New Caledonia and Vanuatu share the same rbcL, trnL–trnF and rps4–trnS haplotype and that other samples of A. polyodon in Australia and the south-western Pacific belong to three separate molecular lineages. One of these lineages is formed by epiphytic A. polyodon from Christmas Island and has a chloroplast haplotype closely related to that of A. listeri, differing by four mutations. The A. listeri haplotype and each of the three A. polyodon lineages are associated with morphological characters and are all worthy of recognition as separate species. Asplenium listeri is here expanded to include limestone dwelling populations in the Pacific previously assigned to A. polyodon. This greatly extends the geographic range of A. listeri, and its conservation status should be revised accordingly. Application of correct names to all species in the A. polyodon complex requires further molecular sampling throughout its geographic range and clarification of how type material relates to each of the molecular groups.

Rediscovery and redescription of the rare, critically endangered snake Emmochliophis miops (Serpentes: Colubridae), with comments on its natural history, distribution, and phylogenetic relationships. The description of Emmochliophis miops is based on a single specimen from the Andean slopes of northwest Ecuador collected in 1897. The species had not been collected again until October 2017, when two individuals were found on the western slopes of the Cordillera Occidental of Colombia; this rediscovery is the first record of this species in this country. Herein, the holotype and the new specimens are examined, and a new diagnosis and description of E. miops are provided. Important data about the natural history and conservation status of the species, and comments on the systematic relationships of Diaphorolepis, Emmochliophis and Synophis are presented.

Abstract Dendrolagus mbaiso is a very rare tree kangaroo (Macropodidae) that was previously only known from the high mountain moss forests of the southern and western slopes of the Sudirman Range of the Snow Mountains in Papua. Here, a northern range extension of D. mbaiso is reported from within the traditional area of the Wano people. It was found on elevations from 1500 m to 3600 m. We also provide ethnographic notes from the Wano people, notes on the sympatric occurrence of D. mbaiso with Dendrolagus dorianus and observations on the variation of the fur color.

We report here five new localities across the distribution of the lizard Sphaerodactylus samanensis, extending its current geographic range to the west, in the Cordillera Central of Hispaniola. We also report phenotypic variation in the color pattern and scutellation on throat and pelvic regions of males from both eastern and western populations, which is described below. Furthermore, based on these new data, we confirm that the species is not fitting in its current IUCN category, and in consequence propose updating its conservation status.

Geographic distribution and habitat use of Lepidoblepharis miyatai (Squamata: Sphaerodactylidae), with comments on the taxonomic status of the genus in northern Colombia. We present some ecological and biogeographic data on Lepidoblepharis miyatai, a small and endangered gecko endemic to the northwestern foothills of the Sierra Nevada de Santa Marta (SNSM), 31 years after its description. Based on museum specimens and feld observations, we recorded four new localities with confrmed presence of L. miyatai. We calculated the extent of occurrence and altitudinal distribution of this species reaching 21.3 km2 and from sea level to 360 m respectively. Lepidoblepharis miyatai inhabits plant formations of scrub thorn and tropical deciduous forest. Based on microhabitat data obtained from 88 individuals observed in “Las Tinajas Village” we can state a differential use of three substrates with predominant use of leaf-litter. We consider L. miyatai an endemic species of the northwestern sector of the SNSM with a distribution range limited to the south-west by the occurrence of L. sanctaemartae, and towards the east by a thus far undetermined Lepidoblepharis species (here called Lepidoblepharis cf. sanctaemartae). We do not register sympatry of L. miyatai with any other congener. Accordingly, we consider that the recent records of this species in the southeast sector of SNSM are erroneous, given that the specimens cited as L. miyatai of this zone correspond to Lepidoblepharis cf. sanctaemartae. Finally, a reevaluation of the conservation status of L. miyatai is needed, including precise information of its distribution.

SummaryThe Minas Gerais Tyrannulet Phylloscartes roquettei is currently classified as a Critically Endangered species, and is one of the most poorly known Neotropical birds. Here we report seven new localities for the species in the São Francisco river basin, raising to 17 the number of localities where this species is known to occur. The range of this species was estimated at 33,500 km2, covering a wider habitat spectrum than previously thought, including, in addition to dry forests, riparian and semi-deciduous forests. We believe this species is overlooked because its voice is generally unknown and available plates in field guides are inaccurate.ResumoO cara-dourada Phylloscartes roquettei é atualmente classificado como Criticamente Ameaçado, sendo uma das espécies de aves Neotropicais menos conhecidas. Neste trabalho são apresentadas sete novas localidades de ocorrência da espécie para a bacia do Rio São Francisco, elevando para 17 o número de localidades onde ela é conhecida. A área de ocorrência desta espécie foi estimada em 33,500 km2, ocupando uma gama de hábitats mais ampla do que o suposto anteriormente, incluindo, além das florestas secas, as florestas ciliares e semidecíduas. Acredita-se que esta espécie esteja passando despercebida devido ao desconhecimento de sua voz e à imprecisão das pranchas nos guias de campo disponíveis.
