We present new Gabonese locality records, ecological or morphological data for Pelusios castaneus (Pelomedusidae), Kinixys erosa (Testudinidae), Osteolaemus tetraspis (Crocodylidae), Agama agama (Agamidae), Monopeltis galeata (Amphisbaenidae), Feylinia currori, Trachylepis polytropis (Scincidae), Varanus ornatus (Varanidae), Philothamnus hughesi, Rhamnophis batesii, Toxicodryas adamantea and T. blandingii (Colubridae), Dendroaspis jamesoni jamesoni (Elapidae), Bothrophthalmus brunneus, Limaformosa guirali and L. savorgnani (Lamprophiidae), Atheris squamigera and Bitis nasicornis (Viperidae). One snake species each is newly recorded from Pongara National Park and Nyanga Province, and two each from Batéké Plateau National Park and Haut-Ogooué Province. We refer all records of Toxicodryas pulverulenta from Gabon to T. adamantea. We discuss the use of camera traps for monitoring reptiles in Gabon based on the results of extensive camera trap surveys. We provide geographic coordinates for selected localities mentioned in MHG III–VI.

We present new Gabonese locality records, ecological and morphological data and unpublished material for Pelusios gabonensis (Pelomedusidae), Kinixys erosa (Testudinidae), Hemidactylus mabouia (Gekkonidae), Lepidothyris striatus, Trachylepis affinis (Scincidae), Crotaphopeltis hotamboeia, Dipsadoboa underwoodi and D. viridis (Colubridae), Dendroaspis jamesoni, Naja annulata annulata, N. melanoleuca and N. nigricollis (Elapidae), Atractaspis boulengeri, Limaformosa savorgnani, Polemon fulvicollis, Psammophis mossambicus (Lamprophiidae) and Natriciteres fuliginoides (Natricidae). One skink and two snake species are newly recorded from Haut-Ogooué and Ngounié provinces, respectively. We attribute all records of Psammophis spp. in Gabon to P. mossambicus. We report a case of predation by a Common chimpanzee (Pan troglodytes) on Kinixys erosa in Lopé National Park, by Crotaphopeltis hotamboeia on the Cameroon toad Sclerophrys camerunensis (Anura: Bufonidae), and by a Naja annulata annulata on Thollon's robber tetra Brycinus tholloni (Characiformes: Alestidae).

Anthelephila propensa (Bonadona, 1984), which was described from holotype only (Makokou), was collected in numbers by the 2016 expedition. Specimens were attracted to MV light as well as beaten from lower vegetation.
Anthelephila medleri (Bonadona, 1984), originally described from SE Nigeria, was collected in Gabon for the first time in 2016.
Anthelephila tuberculithorax (pic, 1899), a widespread species in equatorial Africa, was sampled in Gabon for the first time by the 2016 expedition.
Pseudotomoderus compressicollis strangulatus (Pic, 1952) collected in Ivindo NP - first record from Gabon.

An update is provided of current knowledge of the herpetofauna and batrachofauna recorded from caves in Gabon, western Equatorial Africa. No systematic field survey of reptiles and amphibians in Gabonese cave environments has yet been made, and data are available for only 19 (complexes of) caves. This compilation of published records and new observations includes seven reptile and at least nine amphibian species. None of them is restricted to cave environments, and most of the species are adaptable ecologically, being known from pristine as well as from highly degraded environments. All of them can be regarded as trogloxenes. Dedicated surveys, using appropriate methods, will certainly increase this species list considerably.

Atractaspidines are poorly studied, fossorial snakes that are found throughout Africa and western Asia, including the Middle East. We employed concatenated gene-tree analyses and divergence dating approaches to investigate evolutionary relationships and biogeographic patterns of atractaspidines with a multi-locus data set consisting of three mitochondrial (16S, cyt b, and ND4) and two nuclear genes (c-mos and RAG1). We sampled 91 individuals from both atractaspidine genera (Atractaspis and Homoroselaps). Additionally, we used ancestral-state reconstructions to investigate fang and diet evolution within Atractaspidinae and its sister lineage (Aparallactinae). Our results indicated that current classification of atractaspidines underestimates diversity within the group. Diversification occurred predominantly between the Miocene and Pliocene. Ancestral-state reconstructions suggest that snake dentition in these taxa might be highly plastic within relatively short periods of time to facilitate adaptations to dynamic foraging and life-history strategies.

Presented is a compilation of new locality records with natural history data for 49 reptile species in Haut-Ogooué Province, southeastern Gabon, Equatorial Africa. One new snake species record is added to Gabon (Colubridae: Philothamnus hughesi), 14 new reptile species records to Haut-Ogooué Province, three new reptile records for Léconi Park, and 28 new reptile records for Lékédi Park. A predation case is reported of Naja melanoleuca preying on Dasypeltis fasciata and of Boaedon perisilvestris on a micromammal. Nous présentons une compilation de nouvelles mentions de localités accompagnées de notes d'histoire naturelle pour 49 espèces de reptiles de la Province du Haut-Ogooué, sud-est du Gabon, Afrique équatoriale. Nous ajoutons une espèce de serpent (Colubridae: Philothamnus hughesi) à la faune du Gabon, 14 espèces de reptiles à la Province du Haut-Ogooué, 3 espèces de reptiles au Parc de Léconi, et 28 espèces de reptiles au Parc de la Lékédi.

We present new Gabonese locality records, ecological and morphological data or unpublished material for Kinixys erosa (Testudinidae), Osteolaemus tetraspis (Crocodylidae), Agama agama and A. lebretoni (Agamidae), Rhampholeon spectrum, Trioceros cristatus and T. owenii (Chamaeleonidae), Hemidactylus mabouia (Gekkonidae), Holaspis guentheri (Lacertidae), Trachylepis albilabris (Scincidae), Dipsadoboa viridis, Grayia caesar and G. ornata, and Rhamnophis aethiopissa aethiopissa (Colubridae), Boaedon olivaceus, Chamaelycus fasciatus (Lamprophiidae) and Bitis arietans (Viperidae). Two reptile species are newly recorded for Estuaire Province. One snake is added to the list for Ivindo National Park. We reject a first record of Trachylepis makolowodei from Gabon. We document a case of predation by Rhamnophis aethiopissa aethiopissa on Leptopelis aubryi (Anura: Arthroleptidae).

We studied a collection of snakes (Crotaphopeltis hotamboeia, Hapsidophrys lineatus, Philothamnus heterodermus, Rhamnophis batesii [Colubridae], Dendroaspis jamesoni jamesoni, Naja melanoleuca [Elapidae], Aparallactus modestus, Polemon gracilis, Psammophis cf. phillipsii [Lamprophiidae], Letheobia caeca [Typhlopidae], Bitis arietans, B. gabonica and B. nasicornis, and Causus maculatus [Viperidae]) presumably made in Oyem, Woleu-Ntem Province, northeastern Gabon, and housed in the Royal Museum for Central Africa, Belgium. The analysis of the letters sent by the collector to the museum reveals that some of these snakes were actually collected near Franceville in Haut-Ogooué Province. We examined a Hydrophis platurus (Elapidae) presumably originating from Gabon and housed in the collections of the Royal Belgian Institute of Natural Sciences, Brussels, Belgium; an analysis of the collections' entry register indicates that it was in fact probably caught in West Papua. One snake species is newly recorded from Haut-Ogooué and Woleu-Ntem provinces each. The confirmation of the occurrence of Polemon gracilis in Gabon brings the number of reptile species documented for the country to 129. We report a case of predation by Bitis arietans on a bird.

We refute a recent record of Natriciteres variegata (Natricidae) from Gabon.

An ongoing analysis by Piero Carlino and Olivier Pauwels of the new herpetological material collected in June 2016 revealed two new snake records from Ivindo National Park (the lamprophiids Buhoma depressiceps and Hormonotus modestus). This brings to 64 the number of reptile species confirmed from the park, which represents exactly half of the 128 reptile species currently inventoried from Gabon, and confirms the exceptional herpetological diversity and conservation value of the park.

Some ecological information:
dung beetles (Insecta: Coleoptera: Scarabaeidae s.l.) traps produced max 240 (!) individuals per trap per 2 nights (traps installation time ~6:30 on the morning, traps control time ~16:00 on the 2nd day).
In average, there are 10 species of coprophagous Scarabaeidae per trap.
The number of individuals seems stable (200-240 spp per trap) even at places where 2 traps were installed just 2 m one from another.
