A new species of <Emphasis Type="Italic">Brasiliomyces</Emphasis> (Erysiphaceae) on <Emphasis Type="Italic">Dalbergia cultrata</Emphasis> var. <Emphasis Type="Italic">cultrata</Emphasis> from Thailand

A powdery mildew fungus on leaves of Dalbergia cultrata var. cultrata (Fabaceae) collected at the Queen Sirikit Botanical Garden in northern Thailand is proven to be a new species of the genus Brasiliomyces and is described as B. chiangmaiensis sp. nov. with light and SEM micrographs. Differences in known Brasiliomyces species are discussed, and a key to species of this genus is provided.     

Bewsiella Domrow (Acarina: Mesostigmata): a revision and the description of new species

The genus Bewsiella is considered to comprise a considerable number of species, despite having been regarded as monotypic. The structure of the male spermadactyl is proposed as a key character for separating congeneric species. This character seems likely to bear phylogenetic information on both the mites themselves and their hosts. Since the male of Bewsiella fledermaus Domrow, the type-species, has not been found, it is impossible to define the morphology of this species based on both sexes. Consequently, all mites that share many characters with the female of B. fledermaus are placed in a B. fledermaus species group. B. aelleni (Till) is considered as a valid species and both sexes and the protonymph are redescribed and illustrated. B. nycteris n. sp., B. emballonuris n. sp., B. cloeotis n. sp., B. haradai n. sp. and B. coelopos n. sp. are described and illustrated. The genus Bewsiella was originally allocated to the family Laelapidae and later transferred to the family Macronyssidae. Recently, the genus was returned to the Laelapidae, and some evidence supporting this action was obtained during the present study, but further studies are required for confirmation.     

The fairy shrimp genus Branchinella Sayce (Crustacea: Anostraca: Thamnocephalidae) in Western Australia,including a description of four new species

The genus Branchinella is diverse in Western Australia, with 18 species, including four new species described here. B. complexidigitata n. sp. is characterized by an intricate frontal appendage, unlike any within the genus. The other three are less remarkable; B. halsei n. sp. is like B. lyrifera, B. kadjikadji n. sp. belongs to the B. affinis group and B. nana n. sp. is similar to B. simplex; similarities are based on frontal appendage and to a lesser extent on the second antennae and penis. Only two species, B. affinis and B. longirostris, are common and widespread; many of the remainder being localized endemics. The high diversity in Western Australia is explained by broad latitudinal range, habitat diversity, and great age and isolation of the landscape.     

Ilyocryptus thailandensis sp. nov. (Cladocera: Anomopoda: Ilyocryptidae) from North Thailand

Previously only a single species of Ilyocryptus Sars , 1862 (Cladocera: Anomopoda: Ilyocryptidae) was reported from Thailand, I. spinifer Herrick , 1882. However, our examination of numerous samples from this country resulted in the discovery of four other species of Ilyocryptus. Ilyocryptus thailandensis sp. nov. is described from two adjacent water bodies in Uttaradit Province, North Thailand. It has at least two characters which distinguish it from any other species of the Ilyocryptus: (1) a row of lateral setae reaching medial anus, and continuing along preanal margin up to base of the postabdomen; (2) a large projection bearing the sensory setae, situated on the coxal region of antenna II. It appears to be a rare species, may be, endemic of the North Thailand.     

A new genus, Thailepidonia gen. nov., based on T. yoshiyasui sp. nov. (Lepidoptera, Lecithoceridae) from Thailand

A new genus, Thailepidonia gen. nov. of the family Lecithoceridae, is described based on a new species, T. yoshiyasui sp. nov. from Thailand.     

Eodiaptomus phuphanensis n. sp., a New Freshwater Copepod (Calanoida: Diaptomidae) from the Phu Phan National Park,Thailand

Eodiaptomus phuphanensis n. sp. is described from two localities in the Phu Phan National Park, northeast Thailand. The new species is the eighth member of the genus Eodiaptomus and the third species recorded from Thailand. It belongs to the lumholtzi‐group, and is most closely related to E. sanoamuangae Reddy and Dumont , 1998. The third endopodite‐segment of P2‐P4 in both sexes of E. phuphanensis n. sp. bears seven setae as in E. sanoamuangae, instead of six as in the remaining species of the genus. Nevertheless, the new species can be distinguished from the other congeners by the distinct shape of the endopodite of the male right P5 and the absence of hairs on lateral margins of the female caudal rami.     

Two new Triassic sphinctozoan sponge species from near Kantang, Trang Province, Southern Thailand

A black limestone collected from near Kantan, Trang Province, southern Thailand, contains two species of sphinctozoan sponge which have been namedAmblysiphonella parva n. sp. andPlatythalamiella minima n. sp. The former is a cylindrical chambered sponge with an axial spongocoel and ring chambers.P. minima is an asiphonate and tabular sponge characterized by small chambers arranged in one or two layers above and beside each other. Both are the smallest known species in their respective genera. Hypercalcified sponges have not previously been reported from the Triassic of Thailand.      

Taxonomy, host specificity and dietary implications of Hurleytrematoides (Digenea: Monorchiidae) from chaetodontid fishes on the Great Barrier Reef

Five new and five previously described species of Hurleytrematoides are reported from 19 of 34 chaetodontid species examined from the Great Barrier Reef; new species are H. faliexae n. sp., H. galzini n. sp., H. loi n. sp., H. morandi n. sp., and H. sasali n. sp. Previously described species are H. coronatum, H. fijiensis, H. prevoti, H. bartolii, and H. zebrasomae. The genus is rediagnosed in the light of morphological variation of the new species; the degree of spination and shape of the terminal genitalia distinguish individual species. Species of Hurleytrematoides infect almost every clade of the family Chaetodontidae found on the Great Barrier Reef, but obligate corallivores are not infected. All ten species were found at Heron Island on the southern Great Barrier Reef, but only six at Lizard Island on the northern Great Barrier Reef. For three of the four species not present at Lizard Island, the absence appears to be statistically significant. Although all species are apparently restricted to chaetodontids on the GBR, specificity within the family varies from oioxenous to euryxenous; a core/satellite host paradigm explains the distribution of several species.     

On the fauna of the bristletail family Nicoletiidae (Thysanura) of Thailand

One new species, Lepidospora kwaii sp. n., is described from Thailand. Keys to the families, subfamilies, and genera of the family Nicoletiidae (Thysanura) and to the species of the genus Lepidospora of the world fauna are provided; data on the distribution and evolutionary trends of the bristletails of the genus Lepidospora are given.     

Genetic diversity and phylogenetic position of the subclass Astomatia (Ciliophora) based on a sampling of six genera from West African oligochaetes (Glossoscolecidae, Megascolecidae), including description of the new genus Paraclausilocola n. gen

To more confidently assess phylogenetic relationships among astome ciliates, we obtained small subunit (SSU) rRNA sequences from nine species distributed in six genera and three families: Almophrya bivacuolata, Eudrilophrya complanata, Metaracoelophrya sp. 1, Metaracoelophrya sp. 2, Metaracoelophrya intermedia, Metaradiophrya sp., Njinella prolifera, Paraclausilocola constricta n. gen., n. sp., and Paraclausilocola elongata n. sp. The two new species in the proposed new clausilocolid genus Paraclausilocola n. gen. are astomes with no attachment apparatus, two files of contractile vacuoles, and an arc-like anterior suture that has differentiations of thigmotactic ciliature on the anterior ends of the left kineties of the upper surface. Phylogenetic analyses were undertaken using neighbor-joining, Bayesian inference, maximum likelihood, and maximum parsimony. The nine species of astomes formed a strongly supported clade, showing the subclass Astomatia to be monophyletic and a weakly supported sister clade to the scuticociliates. There were two strongly supported clades within the astomes. However, genera assigned to the same family were found in different clades, and genera assigned to the same order were found in both clades. Thus, astome taxa appear to be paraphyletic when morphology is used to assign species to genera.     

Contributions to the taxonomy of the genera Pachysternum and Cyrtonion (Coleoptera, Hydrophilidae, Sphaeridiinae)

Pachysternum loxodonta sp. n. from the Republic of the Congo and Pachysternum sulawesicum sp.n. from Sulawesi Island, Indonesia are described. The generic status of Pachysternum sculpticolle (Régimbart, 1907) is revised, the species is transferred to the genus Cyrtonion and its differences from C. ghanense Hansen, 1989 are discussed. Taxonomy of Pachysternum is discussed, dividing the genus prelusively into three species groups, one comprising all known Oriental and Eastern Palearctic species, and two comprising the Afrotropical species. Species with unclear positions within the genus Pachysternum or with questionable generic status are left as “Species incertae sedis”.     

Two new species of Lecithoceridae (Lepidoptera,Gelechioidea), with a revised check list of the?family?in?Taiwan

Two species of Lecithoceridae (Lepidoptera, Gelechioidea), Caveana senuri sp. n. and Lecithocera dondavisi sp. n., are described from Taiwan. The monotypic Caveana Park was described from Thailand, based on Caveana diemseoki Park, 2011. Lecithocera Herrich-Schäffer, 1853 is the most diverse genus of the family, comprising more than 300 species worldwide. Lecithocera dondavisi sp. n. is the largest species of the genus so far, and closely resembles the Indian species, Lecithocera praeses Meyrick, 1919. A revised check list of the family in Taiwan is provided.     

New species and new data on Protrinemuridae and Nicoletiidae (Zygentoma) from Eastern Asia and Pacific islands

Four new genera and eleven new species of Zygentoma thysanurans (families Protrinemuridae and Nicoletiidae) are described and some faunistic novelties reported from Oriental and Australian Regions, viz.: Protrinemura leclerci n. sp., from northern Thailand, Protrinemurella allacrotelsoides n. gen. n. sp., from southern Thailand, and Protrinemuroides celebensis n. gen. n. sp., from the Celebes islands (Protrinemuridae), Lepidospora (L.) digitata n. sp., from northern Thailand, L. (L.) deharvengi n. sp., from the Celebes, and Pseudobrinckina anempodiata n. gen. n. sp., from northern Thailand (Nicoletiidae: Coletiniinae), Gastrotheus (G.) papuanus n. sp., from Papua-New Guinea (Nicoletiidae: Atelurinae), and Metrinura celebensis n. sp., from the Celebes, Trinemurodes anomalocoxa n. sp., from southern Thailand, T. bedosae n. sp., from northern Thailand, and Allotrinemurodes thai n.gen. n. sp., from northern Thailand (Nicoletiidae: Subnicoletiinae). Bharatatelura malabarica Mendes is reported for the first time off the Indian sub-continent (in Suva). Proatelura jacobsoni Silvestri is recorded in Macao (southern China) and in the Moluccas islands and notes are presented on its male sex. Gastrotheus (Lasiotheus) nanus (Escherich) is found for the very first time in Macao, in Cook islands and in Niue. Identification keys are provided to Protrinemuridae genera and to species of Trinemurodes, and modifications are suggested to previously presented keys to Nicoletiidae genera and to Lepidospora and Metrinura species.     

Phylogenetic revision of Bonjeania Irwin & Lyneborg (Diptera: Therevidae)

The endemic Australian genus Bonjeania Irwin & Lyneborg is revised. Seven species are described as new: B. angelikae sp.n., B. clamosis sp.n., B. dynastis sp.n., B. flavofemoralis sp.n., B. irwinae sp.n., B. orphne sp.n. and B. trilineata sp.n. Three species, B. actuosa (White), B. nitidifrons (Macquart) and B. segnis (White), are redescribed. All species of Bonjeania were compared in a cladistic analysis with Agapophytus albobasalis Mann and five exemplars of the speciose sister genus Parapsilocephala Kröber, and the phylogenetic relationships of Bonjeania discussed. The male genitalic musculature of B. clamosis sp.n. is described and figured, and discussed with respect to previous studies on other Therevidae.     

Boeckella antiqua n. sp. (Copepoda,Calanoida, Centropagidae) from Patagonia

Boeckella antiqua n. sp. from samples collected in an ephemeral pond on the Patagonian plateau is described and illustrated. Diagnostic features of B. antiqua are almost exclusively related to the male fifth pair of legs, females being almost indistinguishable from those of the closely related B. poppei. The two-segmented, spine-bearing left endopod of the male fifth leg suggests that it may be the basal species in the genus.     

Revision of the genus <Emphasis Type="Italic">Nuchequula</Emphasis> with descriptions of three new species (Perciformes: Leiognathidae)

The leiognathid genus Nuchequula can be defined by the following combination of characters: mouth protruding downward; a narrow band of small, slender, villiform teeth in both jaws; teeth on upper jaw strongly recurved; the lateral line almost complete; a dark blotch on the nape. Although the genus was first established as a subgenus of Eubleekeria, it is here raised to generic level on the basis of the aforementioned morphological characters and recent molecular biological evidence. The genus comprises six valid species: N. blochii (Valenciennes 1835), distributed in India and Thailand; N. flavaxilla sp. nov., occurring only at Panay I., Philippines; N. gerreoides (Bleeker 1851), widely distributed in the Indo-West Pacific, from the Persian Gulf to Cape York, Australia, and north to Taiwan; N. glenysae sp. nov., from northern Australia and Ambon, Indonesia; N. longicornis sp. nov., from the Gulf of Thailand and Indonesia; and N. nuchalis (Temminck and Schlegel 1845), occurring in southern China including Taiwan, and southern Japan. Diagnostic characters of the species belonging to the genus are as follows: N. blochii—breast scaled, cheek naked, and a conspicuous black blotch distally on spinous dorsal fin; N. flavaxilla sp. nov.—breast naked, dorsolateral body surface fully scaled, preorbital spine bicuspid and not expanded distally, and second dorsal and anal fin spines conspicuously elongated; N. gerreoides—breast naked, anterior part of dorsolateral surface of body almost completely scaled, and second dorsal and anal fin spines not conspicuously elongated; N. glenysae sp. nov.—breast completely scaled, cheek scaled, and unique complicated sensory canals present on the suborbital area, extending to the nape; N. longicornis sp. nov.—breast naked, dorsolateral body surface fully scaled, preorbital spine bicuspid or tricuspid and extended distally, and second dorsal fin spines only conspicuously elongated; N. nuchalis—breast naked, anterior part of dorsolateral surface of body widely naked, and a conspicuous dark blotch distally on spinous dorsal fin.     

Dasyatis laosensis,a new whiptailed stingray (family Dasyatidae), from the Mekong River of Laos and Thailand

Synopsis Dasyatis laosensis, a new species, is described from the Mekong River where it forms the border between Laos and Thailand. It is the first member of the genus Dasyatis to be described as an endemic freshwater species from Southeast Asia. Bright orange color on the ventral surface of the disc and similar meristic characters indicate that it may be closely related to Dasyatis akajei, a marine species from southern Japan and China, and to Dasyatis sp. undetermined, from the West River in Guangxi, southern China.     

Pichia nongkratonensis sp. nov., a new species of ascomycetous yeast isolated from insect frass collected in Thailand

A yeast strain isolated from insect frass collected in Thailand was found to represent a new species of the genus Pichia. It is described as Pichia nongkratonensis sp. nov. In the phylogenetic tree based on the D1/D2 domain sequences of 26S rDNA, this yeast constitutes a cluster with Pichia dryadoides with high bootstrap confidence level; however, it differs from the latter species by 5.6% base substitutions. Pichia nongkaratonensis resembles P. dryadoides also in the phenotypic characteristics but is distinguished from this species by the assimilation of several carbon and nitrogen compounds.
