Article Reference A new Cangoderces (Araneae, Telemidae) from DR Congo, the first telemid from Central Africa.
Spiders collected as part of a rapid biodiversity survey in lowland forest in Democratic Republic Congo contained a new species of Cangoderces Harington, 1951 (Telemidae). The male of the new Cangoderces wewef sp. n. is characterized by the male palp with a deep triangular dorsal indentation of the bulbus and the apophyses at the base of the embolus. The female is recognized by the shape of the sclerotized spermatheca in the endogyne. The presence of the species in DR Congo fills the huge distribution gap between the species known from South Africa, Kenya and western Africa.

Article Reference Genetic analysis reveals a distinct lineage of hog deer (Axis porcinus) in Kratie province, Cambodia
The hog deer (Axis porcinus) is an endangered cervid with drastic population declines. There are 2 recognized subspecies of hog deer: A. p. porcinus, ranging from Punjab Province in Pakistan, Nepal, and the Northern part of India to Myanmar, and A. p. annamiticus found in Indo-China, Thailand, Laos, Cambodia, and Vietnam. The current geographic range of A. p. annamiticus is still ambiguous. We analyzed variation in the mitochondrial DNA control region (mtDNA CR) to investigate the intra-species structure, differentiation, and demographic history of hog deer from Cambodia (Kratie Province), which we compared with the populations from India and Thailand. We also generated divergence time estimates using a concatenated dataset of complete Cyt b and partial CR. The CR data showed that Cambodian hog deer are genetically differentiated from the mainland Indian and Thai populations, forming a distinct basal clade. The time of divergence indicates that the Cambodian lineage split from the other 2 hog deer lineages around 0.51 Mya, during the Late Pleistocene. The results also suggest strong phylogeographic structure among hog deer: lineage A extends from Terai Arc (foothills of the Himalayas) to Assam, India (A. p. porcinus), lineage B from Manipur, India to Thailand (A. p. annamiticus), and lineage C is only known from Kratie Province, Cambodia. Lineage A exhibited a higher level of genetic diversity than lineages B and C, with recent demographic stability. Thus, the hog deer population in Kratie Province appears to be a distinct lineage that should be treated as an evolutionarily significant unit.

Article Reference Supplementary morphological information for Cornufer manus (Kraus & Allison, 2009) and Cornufer vogti (Hediger, 1934), with information on colour in life
Manus Island is part of the Admiralty Islands, a herpetologically rich but poorly studied area. Seven species of Cornufer (von Tschudi, 1838) are known to occur on the island, five of which have been described. Based on material collected from Manus Island in 2014, we here describe the first female of Cornufer manus and the first male of Cornufer vogti. Additionally, we provide new information on intraspecific variation from a further eight adult males of C. manus, two subadults of C. vogti, as well as the first photographs of both species in life.

Article Reference Detection of Bonobos (Pan Paniscus) in Tropical Rainforest Canopies Using Drone-Based Thermal Imaging: A First Step Towards Accurately Estimating Population Sizes?
Surveying great ape populations is time-consuming and costly, and often relies on generalised parameters, resulting in imprecise population estimates. Using thermal imaging, through thermal cameras fitted on unmanned aerial vehicles, to detect primates directly from the air, may prove a useful alternative to conventional great ape population surveys. This may be especially true for bonobos (Pan paniscus) which, due to their large body size and nesting behaviour, could provide a uniquely identifiable thermal signature. We trialled the use of a thermal drone to record bonobos in their natural environment in the Democratic Republic of Congo, as a first step towards using the technique to survey great apes. Bonobos were observed asleep in their nests during all surveys at different flight speeds and heights, showing potential for the use of thermal drones as a method to survey great apes.

Article Reference Untangling the waterfall damsels: a review of the Mesoamerican genus Paraphlebia Selys in Hagen, 1861 (Odonata: Thaumatoneuridae) with descriptions of 11 new species.
A review of the Mesoamerican genus Paraphlebia Selys in Hagen, 1861 is presented, including diagnoses, illustrations of diagnostic characters, and distribution maps for all species. A key to the known males and females is provided. Eleven new species are described: P. akan Ortega-Salas & González-Soriano. sp. nov., P. chaak Ortega-Salas & González-Soriano sp. nov., P. chiarae Ortega-Salas sp. nov., P. esperanza Ortega-Salas & González-Soriano sp. nov., P. flinti Ortega-Salas & González-Soriano sp. nov., P. hunnal Ortega-Salas & González-Soriano sp. nov., P. itzamna Ortega-Salas, Jocque & González-Soriano sp. nov., P. ixchel Ortega-Salas & González-Soriano sp. nov., P. kauil Ortega-Salas & González-Soriano sp. nov., P. kinich Ortega-Salas & González-Soriano sp. nov., and P. kukulkan Jocque & Ortega-Salas sp. nov.

Article Reference Dragonflies of Cusuco National Park, Honduras; checklist, new country records and the description of a new species of Palaemnema Selys, 1860 (Odonata: Platystictidae)
The odonate fauna of Honduras is poorly documented. Based on 10 years of observations and collections we present an overview of dragonflies from cloud forests in Cusuco National Park, northwestern Honduras. A total of 44 species were reported including at least seven new country records for Honduras we include ecological observations for most species. A new species of Platystictidae (Palaemnema lorae Jocque & Garrison, n. sp. Holotype ♂: HONDURAS: Cortés Dept., CNP, Cantiles, Trail 5, small river close to camp, N15.513457 W88.241681; 1846m, 23 June 2012 collected by Merlijn Jocque, field code: BINCO_HON_12_047, in RBINS) is described and illustrated.

Article Reference Bird bones from Trou de Chaleux and the human exploitation of birds during the late Magdalenian in Belgium
The Trou de Chaleux is a cave site located in Belgium. It delivered a rich late Magdalenian material culture constituted mainly of lithic artefacts but also including bone industries and figurative art. This paper presents the results of the analysis of the large collection of bird remains recovered by E. Dupont in 1865, which was yet unstudied from taphonomical and archaeozoological perspectives. In addition to the taxonomic identification, surface alterations were investigated based on a macro- and microscopic analysis, including an analysis of wear traces and elementary composition. Special attention is devoted to the presence of human modifications such as disarticulation or butchering marks, traces of heating, presence of colourants and traces of bone working. The taphonomic history of the bird assemblage is reconstructed and the use of birds by humans characterized, as well as their importance in past human activities. We also discuss evidence for seasonal exploitation and for reconstructing the local environment and integrate our results with evidence from other Magdalenian assemblages from north-western Europe. At Trou de Chaleux, birds were used for food, as raw material for bone working and for symbolic purposes. The exploitation of avian products was intense, and species have been used for several purposes such as the raven and snowy owl having been exploited both for food and for symbolic reasons. Large bird bones were used as raw material to produce artefacts, but the use-wear analysis did not evidence unambiguous traces related to the use of the objects produced. Despite several limiting factors, the bird material from Trou de Chaleux considerably increases the knowledge of past human exploitation of birds during the late Magdalenian in north-western Europe.
