AbstractIn the current study, we redescribe and revalidate a freshwater crab species of the genus Potamon Savigny, 1816, from northern Iran. Potamon elbursi Pretzmann, 1962, differs from the species it has been synonymised with, Potamon persicum Pretzmann, 1962, mainly by the shape of the first gonopods in males. Consistent and marked genetic divergence was also recognised in the mitochondrial 16S rRNA and cytochrome oxidase subunit I genes. This study elevates P. elbursi to species rank and therefore increases the number of valid species of the genus Potamon to a total of twenty-two.

A New Species

A new species of freshwater crab of the genus Geothelphusa, G. siasiat sp. nov., is described from Hsinchu and Miaoli counties, northwestern Taiwan. The new species can be distinguished morphologically from similar and geographically close species from western Taiwan by a suite of characters of the carapace, ambulatory legs, thoracic sternum, male abdomen, and male first pleopods. Comparisons of the DNA sequences encoding parts of the mitochondrial large subunit (16S) rRNA and cytochrome oxidase subunit I (COI) genes of specimens from western Taiwan further corroborate this finding. The opportunity is taken here to discuss the taxonomy of the poorly known species, Geothelphusa candidiensis Bott, 1967, based on a re-examination of the holotype, and the distribution of Geothelphusa species from western Taiwan. The report of G. siasiat sp. nov. brings the total number of species of Geothelphusa species known to 52.

The presence of the body colour polymorphism in the tropical invasive pest giant African snail is reported for the first time from South India. Three different body colour polymorphs were recognised viz. grey, black and white. The grey body colour is the most common polymorph. The black and white colour polymorphs are found to be in almost equal proportions in the reported localities with the grey counterparts. The cytochrome oxidase subunit I (COI) sequences of the three colour polymorphs are found to be identical. The presence of the body colour polymorphism in south India may be attributed to the avian predation and other selection pressures.

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.
