Status emendation of Mustela aistoodonnivalis (Mustelidae: Carnivora) based on molecular phylogenetic and morphology

The missing-toothed pygmy weasel, Mustela aistoodonnivalis Wu and Kao, 1991, was originally described from Zhouzhi and Zhashui in the Qingling Mountains in Shaanxi province, China. Subsequently it was considered a subspecies of M. nivalis. During a faunal survey of northwest Sichuan, some specimens of M. aistoodonnivalis were collected. Molecular phylogenetic studies showed that M. aistoodonnivalis formed a distinct clade that was sister to M. eriminea based on one mitochondrial gene and six nuclear genes. Morphologically, there was an obvious difference between M. aistoodonnivalis and M. nivalis, especially the lack of the second lower molar. Geometric morphology studies and species delimitation analysis revealed the valid species status of M. aistoodonnivalis. In summary, we confirm that M. aistoodonnivalis is an independent species rather than a subspecies of M. nivalis, and that it is more closely related to Mustela eriminea.

First record of the dotted grouper Epinephelus epistictus (Temminck & Schlegel, 1843) (Perciformes, Serranidae) in Malaysia

Five specimens of Epinephelusepistictus (Temminck & Schlegel, 1843) were collected from a major landing site located on the west coast of Peninsula Malaysia during a fish faunal survey on 23 August 2017. The present study extends the distribution range of E.epistictus southwards from Andaman Sea to the Strait of Malacca. Species identification was confirmed by colour pattern and DNA barcoding (567 bp of cytochrome C oxidase I) of all E.epistictus specimens and nine closely related Epinephelus species. The interspecies genetic distance ranged from 0.002–0.245. This study also presents, for the first time for Malaysia, data on length-weight relationships and otolith measurements. It contributes to a better understanding of taxonomy, and phylogenetic and genetic diversity of E.epistictus.

Checklist of ectoparasitic arthropods among cave-dwelling bats from Marinduque Island, Philippines

This paper constitutes the first ectoparasite faunal survey of bats for Marinduque Island, Philippines. From 1–12 June 2010, 150 bats belonging to 11 species were captured in 11 caves on the island. Each bat was sampled for ectoparasitic arthropods, and a total of 587 individuals representing 21 species, belonging to five families (Acari: Argasidae and Spinturnicidae; Diptera: Nycteribiidae and Streblidae; and Siphonaptera: Ischnopsyllidae) were collected. New host records (new host record) in the Philippines for Brachytarsina cucullata Jobling 1934, B. proxima Jobling 1951, B. werneri Jobling 1951, Raymondia pseudopagodarum Jobling 1951, Eucampsipoda philippinensis Ferris 1924, Nycteribia allotopa Speiser 1901, Nycteribia allotopoides Theodor 1963, Nycteribia parvuloides Theodor 1963, Ancystropus taprobanius (Turk 1950), and Carios batuensis Hirst 1929 were documented. A checklist of the ectoparasitic species known from the Philippines, their distribution, and bat host species is provided.

A new species of the genus Diogenes Dana, 1851 (Crustacea: Decapoda: Anomura: Diogenidae) from Gujarat, northwestern India

A new species of diogenid hermit crab, Diogenes chhapgari n. sp., is described on the basis of material collected during the crustacean faunal survey along the coastal areas of the Gujarat State, northwestern India. The new species is referred to the D. edwardsii (De Haan, 1849) species group and appears closest to D. singaporensis Rahayu, 2015. However, D. chhapgari n. sp. is distinguished from this species by the armature on the fourth segment of the antennal peduncle and carpus of the left cheliped.

Faunal survey and identification key for the trematodes (Platyhelminthes: Digenea) infecting Potamopyrgus antipodarum (Gastropoda: Hydrobiidae) as first intermediate host

A diverse guild of digenean trematodes infects the New Zealand mud snail, Potamopyrgus antipodarum, as firstintermediate host. This manuscript offers an initial systematic treatment of these trematodes and relies on published andnew information. I list 20 trematode species, for which I provide taxonomic affinities, life-cycle information, and anidentification key. A species account section presents photographs, diagnostic information, additional descriptive notes,and information on relevant research concerning the listed species. The major aim of this manuscript is to facilitateresearch on this trematode guild by providing information and identification tools, and by highlighting gaps in our knowledge.

Huntsman spiders (Araneae: Sparassidae) from Xishuangbanna Rainforest, China

An extensive faunal survey of spiders from Xishuangbanna was carried out over one year (July 2006–August 2007) using various collecting techniques (ground pitfall traps, trunk pitfall traps, fogging and hand collecting). Three known Sparassidae species were collected: Heteropoda tetrica Thorell, 1897, Pseudopoda songi Jäger, 2008, and Pseudopoda namkhan Jäger, Pathoumthong & Vedel, 2006, the latter reported for the first time from China. Thelcticopis zhengi sp. nov. is described and illustrated based on males and females. All specimens are deposited in the Institute of Zoology, Chinese Academy of Sciences in Beijing (IZCAS) and Research Institute Senckenberg in Frankfurt am Main (SMF).

A new species of Pseudostomella (Gastrotricha: Macrodasyida: Thaumastodermatidae) from a sandy beach of Kerala, India

During an interstitial faunal survey along the south-west coast of Kerala, India, gastrotrich fauna were found in abundance. Together with species of the genera Xenotrichula, Halichaetonotus and Tetranchyroderma, were present several undescribed thaumastodermatid gastrotrichs belonging to the buccal palp bearing genus Pseudostomella. Adults of the new species are characterized by the following traits: total body length of about 300 μ m; cuticular armature made up of medium sized pentancres covering the entire dorsolateral surface; pre-buccal, grasping palps bearing five, large papillae dorsally and 4-6 smaller papillae ventrally; adhesive apparatus made up of six anterior, 22-24 ventrolateral, two dorsolateral and six posterior adhesive tubes; caudal organ pear-shaped; frontal organ spherical. Pseudostomella cheraensis sp. nov. is the fourth taxon of the genus known from India; however, all the previous species reported hitherto from India have tetrancres instead of pentancres.
