The slow loris (Nycticebus) is a prosimian that is popular among exotic pet lovers. In Japan, many slow lorises have been imported illegally. Prosimians that have been confiscated in raids are protected in Japanese zoos, and the number of such animals has increased. In most cases, the country of origin remains unknown and even the species can be difficult to identify from the animal’s physical appearance alone. We have attempted to resolve this problem by using DNA analysis. DNA samples of five species, consisting of the Pygmy slow loris (Nycticebus pygmaeus), Bengal slow loris (Nycticebus bengalensis), Sunda slow loris (Nycticebus coucang), Javan slow loris (Nycticebus javanicus), and Bornean slow loris (Nycticebus menagensis), were extracted, amplified, and the nucleotide sequences of mitochondrial 12S rRNA, 16S rRNA, and the cytochrome oxidase subunit 1(COI) regions were compared. Differences of nucleic acid sequences of representative individuals were demonstrated.

Based on molecular analysis (12S rRNA, 16S rRNA, 18S rRNA and histone H3) and morphological characters, it was found that Ero juhuaensis Xu, Wang & Wang, 1987 is misplaced and belongs to Mimetus Hentz, 1832. A new combination is suggested, Mimetus juhuaensis (Xu et al., 1987) new combination. The male of M. juhuaensis is described for the first time. Detailed descriptions and illustrations of both sexes, as well as a distribution map of all known species of Mimetidae Simon, 1881 from China are provided.

Rhacophorus yaoshanensis Liu & Hu, 1962 and Theloderma kwangsiensis Liu & Hu, 1962 were described by Liu & Hu (1962) based on two specimens and one specimen, respectively, from the Dayaoshan Ranges, Guangxi, China. Since these two species were described, no additional specimens have been collected from their type localities, presenting an issue for phylogenetic studies of the genera. Five decades later, we have rediscovered R. yaoshanensis and T. kwangsiensis from their type localities. In this paper, we re-describe the two species and conduct a preliminary assessment of their phylogenetic relationships using two mitochondrial DNA genes (12S and 16S rRNA). The results indicate with high support that R. yaoshanensis is closely related to Rhacophorus pinglongensis. Theloderma kwangsiensis is nested within Theloderma corticale, with only 0.0–0.6% pairwise divergence, a level typical of intraspecific variation. Based on both molecular and morphological analyses, we further confirm that T. kwangsiensis is a synonym of T. corticale. Shiwandashan National Nature Reserve, Guangxi Province, China, is a new record for T. corticale.

A new snake eel, Pisodonophis sangjuensis, is described based on 24 specimens collected from the South Sea of Korea (water depth 5–100 m) between 2005 and 2010. This species is characterized by the following morphological features: fleshy protrusions before and behind the posterior nostril; 1–2 regular rows of conical teeth in both jaws, prevomer and vomer are slightly separated from each other; the origin of the dorsal fin above the middle of the pectoral fin; and the pectoral fin is rounded and not elongated. Pisodonophis sangjuensis is most similar to P. cancrivorus in morphology, but the two species differ in their teeth shape (conical in P. sangjuensis vs. granular in P. cancrivorus), and their numbers of vertebrae (143–153 vs. 153–164, respectively). Pisodonophis sangjuensis differs from P. boro in the origin of the dorsal fin (above the middle of the pectoral fin in P. sangjuensis vs. far behind the pectoral fin in P. boro), their numbers of vertebrae (143–153 vs. 170–177, respectively), and their teeth shape (conical in P. sangjuensis vs. granular in P. boro). Pisodonophis sangjuensis is also easily distinguishable morphologically from the remaining seven Pisodonophis spp. worldwide. Molecular analysis using mitochondrial DNA 12S rRNA sequences supported that P. sangjuensis is a new species because of the considerable genetic distance from what appears to be its most closely related species, P. cancrivorus (d=0.068).

European newts (genus Triturus) are widely studied, but their phylogeny is not yet unambiguously resolved. Fragments of mitochondrial DNA experiencing different rates of evolution (the ATPase and 12S rRNA genes) were sequenced in order to test a phylogenetic hypothesis derived from biochemical and behavioral data. Well-supported branches of the existing phylogeny gained support in our study. The monophyletic origin of the hypothesized T. boscai – T. italicus clade remained ambiguous, whereas strong support was gained for the sister-taxon relationship of T. vulgaris and T. montandoni. The position of T. vittatus as a sister taxon to the T. marmoratus species group was also supported. The phylogenetic position of T. alpestris could not be clarified. With an in-group taxon sampling denser than in previous molecular phylogenetic studies and under the a priori selection of species from the genera Cynops, Neurergus and Paramesotriton as out-groups, the monophyly of Triturus was strongly supported. It cannot be excluded, however, that the presumed out-group actually belongs to the in-group, rendering Triturus paraphyletic as was concluded from recently published 12S and 16S rRNA sequence data.
