A new sandstone-dwelling leaf-toed gecko (Gekkonidae: Dixonius mekongensis) from the Thai-Lao border
-
We describe Dixonius mekongensis sp. nov. from sandstone formations in Khong Chiam District, Ubon Ratchathani Province, in extreme eastern Thailand along the Laotian border. The new species differs from all currently recognized Dixonius by the following combination of morphological characters and pattern: maximal known snout-vent length of 51.2 mm; 16 longitudinal rows of dorsal tubercles; 32 to 34 paravertebral scales; 22 to 24 longitudinal rows of ventral scales across the abdomen; seven precloacal pores in males, no pores in females; a marked canthal stripe; and a spotted to uniform dorsal pattern. This description brings the number of Dixonius species to 13, with six species endemic to Thailand.

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.

A new saurolophine dinosaur from the latest Cretaceous of Far Eastern Russia
-
Background Four main dinosaur sites have been investigated in latest Cretaceous deposits from the Amur/Heilongjiang Region: Jiayin and Wulaga in China (Yuliangze Formation), Blagoveschensk and Kundur in Russia (Udurchukan Formation). More than 90% of the bones discovered in these localities belong to hollow-crested lambeosaurine saurolophids, but flat-headed saurolophines are also represented: Kerberosaurus manakini at Blagoveschensk and Wulagasaurus dongi at Wulaga. Methodology/Principal Findings Herein we describe a new saurolophine dinosaur, Kundurosaurus nagornyi gen. et sp. nov., from the Udurchukan Formation (Maastrichtian) of Kundur, represented by disarticulated cranial and postcranial material. This new taxon is diagnosed by four autapomorphies. Conclusions/Significance A phylogenetic analysis of saurolophines indicates that Kundurosaurus nagornyi is nested within a rather robust clade including Edmontosaurus spp., Saurolophus spp., and Prosaurolophus maximus, possibly as a sister-taxon for Kerberosaurus manakini also from the Udurchukan Formation of Far Eastern Russia. The high diversity and mosaic distribution of Maastrichtian hadrosaurid faunas in the Amur-Heilongjiang region are the result of a complex palaeogeographical history and imply that many independent hadrosaurid lineages dispersed without any problem between western America and eastern Asia at the end of the Cretaceous.

A new species of Actinopyga (Holothuroidea: Aspidochirotida: Holothuriidae)
-
Actinopyga is one of the five genera commonly recognised in the family Holothuriidae. This small genus has sixteen species currently considered valid. The present paper describes a new Indo-West Pacific species, Actinopyga caerulea, of which the most striking character is its bluish coloration. The ossicle assemblage of the new species resembles mostly that of A. bannwarthi Panning, 1944 and A. flammea Cherbonnier, 1979.
