The phylogenetic relationships of four nominal south-central Canadian freshwater physids ( Physa (sensu lato) skinneri Taylor, 1954, Physa integra (Haldeman, 1841), Physa gyrina (Say, 1821), and the endemic Physa winnipegensis Pip, 2004) were studied by analyses of combined partial sequences coding for mitochondrial 16S and cytochrome c oxidase (COI) genes. Maximum parsimony and neighbour joining analyses, as well as comparisons with published sequences, supported four major clades of physids, of which three are represented in central Canada. Physa skinneri and P. integra were placed within the Physa fontinalis (L., 1758) and Physa acuta Draparnaud, 1805 clades, respectively. Physa winnipegensis formed a distinct branch within the P. acuta group. An additional, previously unreported and unclassified, morph within the P. acuta group was identified from Lake Winnipeg.

The phylogenetic relationships between 10 of 13 genera of crabs from the superfamily Dorippoidea were investigated using mitochondrial 16S rRNA, 12S rRNA and cytochrome c oxidase subunit I gene sequences. The resultant phylogenetic trees based on the three molecular markers support the division of Dorippidae and Ethusidae as monophyletic families within the Dorippoidea. The inferred inter-generic relationships within Dorippidae concur with groupings based on the overall morphology of the carapace and structures of the male first pleopods.

Seventeen species of Leucophenga subpollinosa species group are described from China (including 11 new species): L. argentina (de Meijere, 1924); L. flavicosta Duda, 1926; L. formosa Okada, 1987; L. nigroscutellata Duda, 1924; L. subpollinosa (de Meijere, 1914); L. umbratula Duda, 1924; L. aculeata sp. nov.; L. acuticauda sp. nov.; L. cultella sp. nov.; L. cyclophylla sp. nov.; L. flaviclypeata sp. nov.; L. fuscipedes sp. nov.; L. gracilenta sp. nov.; L. latipenis sp. nov.; L. magnicauda sp. nov.; L. rhombura sp. nov.; L. rugatifolia sp. nov. A key to all examined species of the subpollinosa group in the present study is provided. The phylogenetic relationships among the 17 species of the subpollinosa group are reconstructed by NJ (Neighbor-joining) and Bayesian analyses using 98 DNA sequences of COI (cytochrome c oxidase subunit I) gene. The pairwise intra- and interspecific p-distances of aforementioned sequences are summarized.

This study aimed to generate the genetic profile of Holothuria (Mertensiothuria) leucospilota (Brandt 1835) from Intan Besar Island, Langkawi, Kedah Darul Aman, Malaysia and then to determine the phylogenetic relationship between H. leucospilota and other members of genus Holothuria available in the GenBank using partial sequences of cytochrome c oxidase I (COI) mitochondrial DNA (mtDNA) gene. In this study, tree topologies of neighbour joining, maximum parsimony and maximum likelihood show that H. leucospilota has its own monophyletic clade clearly distinct from the other species and it is genetically closer to Holothuria (Acanthotrapeza) coluber Semper 1868.

A new pill millipede, Rhopalomeris nagao sp. nov., is described from Vietnam. It is recognized by the following combination of characters: antennal tip with numerous sensory cones; telopods with short prefemoral and femoral trichosteles, with long, straight and acute tuberculiform femoral process, and with shorter lobuliform tibial process; syncoxial lobe being slightly concave medially, syncoxial horns being longer than lobe. A fragment of the cytochrome c oxidase subunit I (COI) gene is also provided for the new species. The K2P genetic distance of the COI between the new species and other Vietnamese glomeridans is from 10.7% to 16.9%. Two genera, Hyperglomeris and Hyleoglomeris, are considered to be non-monophyletic, but more data and samples will be needed for confirmation.

Colour Morphs

Phylogenetic relationships among southern Indian Aphthona species using the cytochrome c oxidase subunit 1 mitochondrial gene (COX1 or COI) is reported. This study confirms colour polymorphism in Aphthona: A. tamila and A. glochidionae; A. marataka and A. macarangae, respectively, could be confirmed as colour morphs. Aphthona phyllanthae is the most diverged taxon according to the genetic distance.

Hyaena Hyaena

Striped hyaena (Hyaena hyaena) is one of the species in danger of extinction and categorized globally as “Under Threatened Organism”. From time to time, different tissue samples and carcasses of the striped hyena are reported in different regions of Anatolia. In this study, 571 bp length of Cytochrome C Oxidase Subunit II (COX 2) of mitochondiral DNA from hair, ears, nails and teeth specimens from six striped hyaenas were amplified and sequenced to determined phylogenetic relationships between close and distant species related to hyaena. Tissue samples using in this study were found randomly at different times in Hatay province, Turkey. According to our results, all colected samples located in Hatay region are the members of H. hyaena species. Moreover, this research is the first molecular research using COX2 gene region for phylogenetic analysis in Turkey. Further investigation can be performed on studies that suggest determining phylogenetic status of striped hyaenas.
