New species of Elaphoidella Chappuis, 1929 and Schizopera Sars, 1905 (Copepoda: Harpacticoida) from two caves in northeastern and southern Thailand.

Two new copepod species from two caves in northeastern and southern Thailand are described. Elaphoidella isana sp. nov.

On the taxonomic status of Oriental populations of the genus Bosminopsis Richard, 1895 (Crustacea: Cladocera).

It is widely accepted among the Cladocera (Crustacea) taxonomists that almost all cosmopolitan taxa are represented by some un-revised complexes of cryptic species. But many macro taxa of the cladocerans are still unrevised. The aim of this work is to analyze the taxonomic status of Oriental populations of the genus Bosminopsis Richard, 1895 (Anomopoda: Bosminidae) based on morphological characters.

Three nuclear protein-coding genes corroborate a recent phylogenomic model of the Branchiopoda (Crustacea) and provide estimates of the divergence times of the major branchiopodan taxa.

The class Branchiopoda (Crustacea) shows great diversity in morphology and lifestyle among its constituent higher-level taxa: Anostraca, Notostraca, Laevicaudata, Spinicaudata, Cyclestherida and Cladocera. The phylogenetic relationships among these taxa have long been controversial. We sequenced three orthologous nuclear genes that encode the catalytic subunit of DNA polymerase delta and the largest and second-largest subunits of RNA polymerase II in the expectation that the amino acid sequences encoded by these genes might be effective in clarifying branchiopod phylogeny and estimating the times of divergence of the major branchiopodan taxa.

Review of the (Branchiopoda: Spinicaudata: Limnadiidae) of Tropical Asia, with the Description of a New Species.

We describe a new species of from the Oriental region using museum specimens collected from India and fresh material from Thailand. This species has egg morphology resembling s. lat.

High diversity of Cladocera (Crustacea: Branchiopoda) in a Ramsar site Lake Kud-Thing, Northeast Thailand.

An intensive study of cladoceran diversity in Lake Kud-Thing, a Ramsar site of Bueng Kan Province, Thailand, was conducted. One hundred and twenty-five qualitative samples were collected from 15 localities during the period from June 2012 to November 2014. A total of 58 species belonging to 38 genera was recorded.

Phyllodiaptomus (Phyllodiaptomus) roietensis, a new diaptomid copepod (Copepoda, Calanoida) from temporary waters in Thailand and Cambodia, with a key to the species.

Phyllodiaptomus (Phyllodiaptomus) roietensis was collected from temporary water bodies in Roi Et and Nakhon Ratchasima provinces in northeastern Thailand and Kampong Thom Province in central Cambodia. The new species is closely related to Phyllodiaptomus (P.) surinensis Sanoamuang & Yindee, 2001 in that it shares common morphological characters in the males: urosomites 2-3, P5 intercoxal sclerite, right P5 Exp-2, and left P5 Exp.

sp. nov., A New Laevicaudatan Clam Shrimp with Asymmetrically Modified Thoracopods from Yunnan, China (Crustacea: Branchiopoda).

Laevicaudata has a nearly global distribution, but only a few records from China. We present a new (Crustacea: Branchiopoda: Laevicaudata) species, sp. nov.

A new species of the genus Anthalona Van Damme, Sinev & Dumont, 2011 (Cladocera: Anomopoda: Chydoridae) from North-East Thailand.

A new species of Cladocera, Anthalona spinifera sp. nov., is described from North-East Thailand.

A new Theosbaena (Thermosbaenacea: Halosbaenidae) from Thailand.

We present a second species of Theosbaena, which also represents the second species of Thermosbaenacea from mainland Asia. This new species is apparently endemic to a limestone cave in Nakhon Sawan Province in central Thailand. Theosbaena kiatwongchai n.

Psammon rotifers in Central Vietnam, with the descriptions of three new species (Rotifera: Monogononta).

In order to address the dearth of information on Rotifera in Vietnam, and especially on rotifers inhabiting freshwater psammon in Southeast Asia, we collected and examined twenty-five hygropsammon samples from Bau Thiem Lake, Thua Thien Hue Province, central Vietnam. A total of eighty-nine species-level rotifer taxa were identified, belonging to 21 genera and 13 families. Of these, 48 taxa (54%) are new to Vietnam, including three species, Lecane climacois Harring & Myers, 1926, Notommata cerberus (Gosse, 1886) and Trichocerca intermedia (Stenroos, 1898) that are new to the Oriental region, and three species, Lecane phapi n.

Two new stygobiotic species of Elaphoidella (Crustacea: Copepoda: Harpacticoida) with comments on geographical distribution and ecology of harpacticoids from caves in Thailand.
