Although representatives of Peripatidae are widely distributed in South-East Asia, only three valid species of Eoperipatus and one species of Typhloperipatus have been described from this region. According to previous reports, the three species of Eoperipatus show little morphological variation and are difficult to distinguish from each other. In this study, we describe a new species of Eoperipatus from Vietnam, E. totoro sp. nov., using morphological (light and scanning electron microscopy) and molecular data (mitochondrial COI and 12S rRNA sequences). A comparison with specimens of an undescribed species of Eoperipatus from Thailand revealed novel species-specific characters, including the characteristics of male crural complexes, distinct types of scales on the ventral body surface, the inner structure of the circular pits on the male genital pad, and the position and size of the anal gland pads in males. The results of our molecular analyses correspond with those of morphological studies. In contrast to previous assumptions, our findings suggest a high diversity of the South-East Asian Peripatidae, which requires further exploration. © 2013 Elsevier GmbH. Source

Th e taxonomic reasons for regarding L. draperi Séguy, 1933, sp. rev., as a valid species instead of a synonym of L. tentaculata (De Geer, 1776) and for treating L. quaerens Villeneuve, 1936, syn. n., as a junior synonym of L. sericipalpis Stein, 1904 are given. A revised key for the Palaearctic members of the Lispe tentaculata species-group is given. Data on ecology, distribution and feeding preferences are provided. © Nikita Vikhrev. Source

According to kin selection theory, competition among monoclonal animals must be lower than between unrelated individuals. Thus, we propose that home range and core area overlap in parthenogenetic lizards will be broader than female range overlap in similar gonochoristic species. To test this hypothesis, we examined home range locations and space use of parthenogenetic Armenian Rock Lizards (Darevskia armeniaca) and compared them with home range locations and space use of gonochoristic species. We demonstrated that parthenogenetic Rock Lizards have a total range structure typical of insectivorous lizards, consisting of a sally zone, a home range, and one or more core areas. Some core areas contained activity centers, associated strongly with key basking sites and shelters. Provisional residents were found within the same range for 1 or 2 years, whereas wanderers visited study sites for 1 or 2 weeks per season. Settlement structure varied greatly among years. Home ranges, core areas, and even activity centers and basking sites of parthenogenetic females overlapped extensively, unlike in females of nonparthenogenic species. Monoclonal origins and high level of relatedness within unisexual species are possible explanations of the extended range overlap among parthenogenetic females.

Three species of Lispe were recorded for Dominican Republic, namely L. nasoni Stein, 1898; L. probohemica Speiser, 1914 and L. sordida Aldrich, 1913. Two new synonymies are proposed: L. probohemica = L. argentea Snyder, 1954 syn.n. and L. sordida = L. bahama Snyder, 1958 syn.n. Female of L. probohemica is redescribed. Identification key for Dominican Lispe is proposed. © RUSSIAN ENTOMOLOGICAL JOURNAL, 2016. Source

The fauna of the Hydrotaea parva group and the here proposed Hydrotaea glabricula group is considered. Identification keys for the Eurasian and Afrotropical faunas of the Hydrotaea glabricula group and for the Palaearctic and Eurasian faunas of the Hydrotaea parva group are given. Five new species H. semiflava sp.n. (from Sri Lanka), H. elephans sp.n., H. ozerovi sp.n., H. portschinskyi sp.n. and H. stackelbergi sp.n. (all from Thailand) and one subspecies H. polita kenyana ssp.n. (from Kenya) are described. Two new synonymies are proposed: Hydrotaea atrisquama Ringdahl, 1925 = Hydrotaea multipilosa Shinonaga et Kano, 1983, syn.n. and Hydrotaea parva Meade, 1889 = Hydrotaea exigua Shinonaga et Kano, 1983, syn.n. © RUSSIAN ENTOMOLOGICAL JOURNAL, 2015.
