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.

A new cave-dwelling Gekko (Gekko) from Lopburi Province, central Thailand (Squamata, Gekkonidae)
-
We describe Gekko pradapdao sp. nov. from Tham Khao Chan (Khao Chan Cave), Tha Luang District, Lopburi Province, in central Thailand. The new species, a member of the subgenus Gekko, differs from all currently recognized Gekko species by the following combination of morphological characters and pattern: maximal known snout-vent length of 127.1 mm, lack of contact between nostrils and rostral, 24–28 interorbital scales between supraciliaries, 89–91 scale rows around midbody, 16–18 dorsal tubercle rows at midbody, 30–34 ventral scale rows at midbody, 11–13 precloacal pores in males, a single postcloacal tubercle on each side of the base of the tail, 13–16 subdigital lamellae on 1st toe and 17–19 on 4th toe, no Y-shaped mark on head, non-banded dorsal pattern on a dark chocolate brown to black background, and a dark brown iris. Urgent actions should be taken to evaluate the conservation status of the new species.

A new Four-clawed Gecko from limestone hills in Lopburi Province, central Thailand (Squamata, Gekkonidae: Gehyra)
-
We describe Gehyra wongchan sp. nov. from Tham Khao Chan (Khao Chan Cave), Tha Luang District, and Wat Khao Wong, Kok Samrong District, in Lopburi Province, central Thailand. The new species differs from all currently recognized Gehyra by the following combination of morphological characters and dorsal color pattern: maximal known snout–vent length of 52.4 mm, 8–10 supralabials, 76–80 dorsal and 48–50 ventral scale rows around midbody, absence of skin folds on limbs, 17 or 18 preanofemoral pores in males in a continuous series extending to mid-length of femur (pores absent in females), tail not- to moderately widened behind vent in adults, a single row of widened subcaudals, digits and toes unwebbed, 7 or 8 divided subdigital lamellae on 4th toe, and a dorsal pattern with white spots as large or larger than adjacent crescentic black markings on a beige to light-brown background.

A new gecko from the earliest Eocene of Dormaal, Belgium: a thermophilic element of the ‘greenhouse world’
-
We here describe a new gekkotan lizard from the earliest Eocene (MP 7) of the Dormaal locality in Belgium, from the time of the warmest global climates of the past 66 million years (Myr). This new taxon, with an age of 56 Myr, together with indeterminate gekkotan material reported from Silveirinha (Portugal, MP 7) represent the oldest Cenozoic gekkotans known from Europe. Today gekkotan lizards are distributed worldwide in mainly warm temperate to tropical areas and the new gecko from Dormaal represents a thermophilic faunal element. Given the Palaeocene–Eocene thermal maximum at that time, the distribution of this group in such northern latitudes (above 50° North – the latitude of southern England) is not surprising. Although this new gekkotan is represented only by a frontal (further, dentaries and a mandibular fragment are described here as Gekkota indet. 1 and 2—at least two gekkotan species occurred in Dormaal), it provides a new record for squamate diversity from the earliest Eocene ‘greenhouse world’. Together with the Baltic amber gekkotan Yantarogekko balticus, they document the northern distribution of gekkotans in Europe during the Eocene. The increase in temperature during the early Eocene led to a rise in sea level, and many areas of Eurasia were submerged. Thus, the importance of this period is magnified by understanding future global climate change.
