The dercetid fishes (Teleostei, Aulopiformes) from the Maastrichtian (Late Cretaceous) of Belgium and The Netherlands
-
Several partial skeletons from the marine Maastrichtian deposits of Belgium and the Netherlands allow to recognize four species of Dercetidae, two of which are new: Dercetis triqueter, Ophidercetis italiensis, Cyranichthys jagti sp. nov. and Apuliadercetis indeherbergei sp. nov. This newly studied material greatly enlarges the stratigraphic and paleogeographic ranges of the four concerned dercetid genera.

A new sandstone-dwelling leaf-toed gecko (Gekkonidae: Dixonius hinchangsi) from Khon Kaen Province, northeastern Thailand
-
We describe Dixonius hinchangsi sp. nov. from a sandstone area near Hin Chang Si, Khon Kaen Province, northeastern Thailand. The new species differs from all currently recognized Dixonius by the following combination of morphological characters and pattern: maximal known snout-vent length of 50.1 mm, 12 longitudinal rows of dorsal tubercles; 30 to 34 paravertebral tubercles; 23 to 27 longitudinal rows of ventral scales across the abdomen; six to eight precloacal pores in males, no pores in females; no canthal stripe; strongly barred lips; and a spotted to uniform dorsal pattern in males and females. We provide a cranial osteological description and a phylogenetic analysis of the new species. This discovery brings the number of recognized Dixonius species to 19, among them nine species endemic to Thailand.

Along the Mekong: a new leaf-toed gecko (Gekkonidae: Dixonius sambhupura) from northeastern Cambodia
-
We describe Dixonius sambhupura sp. nov. from the western bank and Koh Klap (island) of the lower Mekong River in Kratie Province, northeastern Cambodia. The new species differs from all currently recognized Dixonius by the following combination of morphological characters and pattern: maximal known snout-vent length of 49.0 mm, 14 or 16 longitudinal rows of dorsal tubercles; 34 to 37 paravertebral tubercles; 24 to 27 longitudinal rows of ventral scales across the abdomen; six precloacal pores in males, no pores in females; no marked canthal stripe; strongly barred lips; and a spotted to blotched dorsal pattern in adult males and females. We provide a cranial osteological description and a phylogenetic analysis of the new species. The discovery of this new species endemic to Cambodia brings the number of recognized Dixonius species to 20.

Phylogenomics of Psammodynastes and Buhoma (Elapoidea: Serpentes), with the description of a new Asian snake family
-
Asian mock vipers of the genus Psammodynastes and African forest snakes of the genus Buhoma are two genera belonging to the snake superfamily Elapoidea. The phylogenetic placements of Psammodynastes and Buhoma within Elapoidea has been extremely unstable which has resulted in their uncertain and debated taxonomy. We used ultraconserved elements and traditional nuclear and mitochondrial markers to infer the phylogenetic relationships of these two genera with other elapoids. Psammodynastes, for which a reference genome has been sequenced, were found, with strong branch support, to be a relatively early diverging split within Elapoidea that is sister to a clade consisting of Elapidae, Micrelapidae and Lamprophiidae. Hence, we allocate Psammodynastes to its own family, Psammodynastidae new family. However, the phylogenetic position of Buhoma could not be resolved with a high degree of confidence. Attempts to identify the possible sources of conflict in the rapid radiation of elapoid snakes suggest that both hybridisation/introgression during the rapid diversification, including possible ghost introgression, as well as incomplete lineage sorting likely have had a confounding role. The usual practice of combining mitochondrial loci with nuclear genomic data appears to mislead phylogeny reconstructions in rapid radiation scenarios, especially in the absence of genome scale data.
