A taxonomic revision of the genus Lasianthus Jack. (Rubiaceae) from Thailand

A taxonomic revision of the genus Lasianthus Jack. from Thailand is made based on specimens in BKF, BK, L, AAU, K, BM, E, P, KEP, SING and PSU etc. Three species and three varieties are described as new; a new combination, L. trichophlebus subsp. barbellatus ( Ridley) H. Zhu, is made; eight species and five varieties are found to represent new records to Thailand; seven species, i.e. L. brevidens Craib, L. densifolius Miq., L. incomptus Craib, L. scalaris Craib, L. penicillatus Craib, L. virgatus Craib and L. zambalensis Elmer, axe reduced to synonyms; two species, L. brevipes Craib and L. lowianus King et Gamble are moved to the genus Saprosma; the delimitation of some species is clarified. As a result, fifty-two species, one sub-species and twelve varieties are recognized in the genus Lasianthus from Thailand.     

Four new species and one new record of Lasianthus (Rubiaceae) from Thailand

Four new species of the genus Lasianthus are described from Thailand and accompanied with taxonomic remarks. These new taxa are: L. ellipsoideus, L. flavi-hirtus, L. loeiensis and L roosianus. One variety, L. politus var. insularis is considered to be a synonym of L. coronatus extending the range of this species to Thailand.     

Three new species of Leptolalax from Thailand (Amphibia, Anura, Megophryidae)

Three new megophryid species, Leptolalax melanoleucus, L. fuliginosus, and L. solus, are described from southwestern and southern Thailand on the bases of acoustic and morphological characteristics. Leptolalax melanoleucus and L. fuliginosus are similar to L. pelodytoides from northern Thailand, but differ from it completely in advertisement call characteristics and ventral color. Leptolalax solus is similar to L. heteropus from peninsular Malaysia, but differs from it by advertisement call, as well as by some body proportions. The distributional pattern of Leptolalax within Thailand is discussed.     

Lernanthropid copepods (Siphonostomatoida) parasitic on fishes of the Gulf of Thailand

Five species of copepods (Siphonostomatoida: Lernanthropidae) parasitic on fishes of the Gulf of Thailand are reported. They are: Lernanthropus corniger Yamaguti, 1954 from Megalaspis cordyla (Linnaeus); L. latis Yamaguti, 1954 from Lates calcarifer (Bloch); L. nemipteri Jayasree & Pillai, 1976 from Scolopsis lineata Quoy et Gaimard; L. sillaginis Pillai, 1963 from Priacanthus tayenus Richardson; and Norion tayenus n. sp. from P. tayenus. Except for L. sillaginis, the remaining four species are new to Thailand. Lernanthropus priacanthi Kirtisinghe, 1956 is transferred to Norion as N. priacanthi (Kirtisinghe, 1956) n. comb.     

New Liphistius species (Araneae, Mesothelae) from southern Thailand and northern Malaysia

Four new Liphistius species are described from southern Thailand: L. rufipes (also occurring in northern Malaysia), L. fuscus, L. castaneus and L. albipes. The males of L. bicoloripes Ono and L. schwendingeri Ono are described for the first time. Zoogeography and taxonomic relationships are discussed, notes are given on the natural history of each species.     

Diversity and endemism of Murinae rodents in Thai limestone karsts

This study aims to investigate the species diversity of rodents living in karst ecosystems of Thailand. A survey has been conducted throughout Thailand, 122 karsts sampled and 477 Murinae rodents live-trapped. Phylogenetic reconstructions were carried out using two mitochondrial markers (cytb, COI). A sequence-based species delimitation method completed by the analysis of the level of genetic divergence was then applied to define species boundaries within our dataset. The phylogenetic position of Niviventer hinpoon was also investigated and sequences obtained from the holotype specimen of this species were used to reliably identify samples of N. hinpoon. A total of 12 described Murinae species, corresponding to 17 deeply divergent genetic lineages, were encountered in limestone karsts of Thailand. Our study revealed an important genetic diversity within the traditionally recognized species Maxomys surifer (four highly divergent genetic lineages), Leopoldamys neilli (two highly divergent genetic lineages) and Berylmys bowersi (two highly divergent genetic lineages). These species could be considered as species complex and require further taxonomic work. This study also provides valuable information on the distribution of the two rodent species endemic to limestone karsts of Thailand, L. neilli and N. hinpoon. Leopoldamys neilli was the most abundant species encountered in Thai karsts during our survey. However, L. neilli specimens from western Thailand are genetically highly divergent from the remaining populations of L. neilli and could represent a separate species. Niviventer hinpoon, phylogenetically closely related to N. fulvescens, is much rarer and its distribution limited to central Thailand. Most of the other captured species are typically associated with forest ecosystems. This study suggests that limestone karsts play a key role in the preservation of the rodent species endemic to such habitat, but they would also provide refuges for the forest-dwelling Murinae rodents in deforested regions.     

Microfungi on the Pandanaceae: Linocarpon lammiae sp. nov., L. siamensis sp. nov. and L. suthepensis sp. nov. are described with a key to Linocarpon species from the Pandanaceae

Linocarpon species are reported from Pandanaceae in Australia, Brunei, Hong Kong, Nepal, New Zealand, Philippines, Seychelles, Thailand and Vanuatu. Linocarpon lammiae sp. nov. were collected on decaying leaves of Pandanus tectorius in Hong Kong. Linocarpon siamensis sp. nov. and L. suthepensis sp. nov. were collected from decaying leaves of P. penetrans in Thailand. These taxa are described, illustrated and compared with Linocarpon species with similar ascospore morphology and dimensions. Included are a synoptic table, which compares the new species to similar known species, and a dichotomous key to species of Linocarpon known from members of the Pandanaceae.     

Review of the oriental leafhopper genus Lampridius (Hemiptera: Cicadellidae: Deltocephalinae), with description of a related new genus

The leafhopper genus Lampridius Distant, 1918 (type species: L. spectabilis Distant, 1918 ) is redescribed, and a second species, L. cuspidatus sp. nov. (Thailand: Loei), is described. A related new genus Paralampridius gen. nov. and four new species are described: P. mimicus sp. nov. (China: Guangdong, Hainan), P. rotundatus sp. nov. (Thailand: Loei), P. sinuatus sp. nov. (Thailand: Loei, Suphanburi, Petchaburi), and P. truncatus sp. nov. (Thailand: Chaiyaphum, Ubon Ratchathani). Both genera are tentatively included in the tribe Opsiini, although only Lampridius has paired aedeagal shafts with separate gonopores. All six species are illustrated, and a key is provided for their identification. Problems with the current tribal classification are discussed in light of the present discovery of closely related species that show variation in characters previously assumed to be stable at the tribal level in the subfamily Deltocephalinae.     

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.     

Three new species of Lentinus from northern Thailand

There have been few studies on the taxonomy and biodiversity of the genus Lentinus in Thailand, which is a genus of edible mushrooms. Recently, collections from 17 sites in northern Thailand yielded 47 specimens of Lentinus sensu lato. Three were shown to be new species of Lentinus sensu stricto and Lentinus roseus, L. concentricus and L. megacystidiatus are introduced in this paper. The new species are described and illustrated with line drawings and are justified and compared with similar taxa. Furthermore, ITS sequence data do not match closely with any species presently lodged in GenBank.     

On the spider genus Liphistius (Araneae: Mesothelae) in Thailand and Burma

Seven of the ten Liphistius species already known from Thailand and Burma are characterized; three new species, L. lannaianus sp.n., L. marginatus sp.n., L. thaleban sp.n., and the males of L. lordac Platnick & Scdgwiek and L. niphanae Ono are described. Taxonomy and relationships are discussed; considerable variation in female internal genitalia is shown. Notes are given on natural history, distribution, burrow structure, phenology and behaviour.     

Liparis rubescens sp. nov. (Orchidaceae) from Thailand

In the context of an ongoing revision of the orchid genus Liparis in Thailand, we describe and illustrate a new species under the name L. rubescens Tetsana, H. A. Pedersen & Sridith. Morphologically, it is particularly similar to L. dumaguetensis Ames from the Philippines, but it differs in the shape of the lateral sepals and in several characters of the labellum. Among the Liparis species already known from Thailand, L. atrosanguinea Ridl. bears a certain resemblance to the new species, but not so much as to make misidentifications likely. So far, L. rubescens is only known from Khao Nan National Park in the southern Thai province of Nakhon Si Thammarat, but we suggest that it should also be searched for in other parts of peninsular Thailand, southernmost Myanmar and Peninsular Malaysia.     

Evidence of complex phylogeographic structure for the threatened rodent <Emphasis Type="Italic">Leopoldamys neilli</Emphasis>, in Southeast Asia

Leopoldamys neilli is a threatened murine rodent species endemic to limestone karsts of Thailand. We have studied the phylogeography of L. neilli using two mitochondrial markers (cytb, COI) and one nuclear fragment (bfibr), in order to assess the influence of its endemicity to karst habitat. One hundred fifteen individuals of L. neilli were collected in 20 localities throughout the geographic range of this species in Thailand. Our study revealed strong geographic structure of the mtDNA genetic diversity: six highly differentiated, allopatric genetic lineages were observed in our dataset. They exhibit a very high degree of genetic divergence, low gene flow among lineages and low levels of haplotype and nucleotide diversities within lineages. Our results suggest that L. neilli’s populations are highly fragmented due to the scattered distribution of its karst habitat. The most divergent lineage includes the populations from western Thailand, which have been separated from the other genetic lineages since at least the Early Pleistocene. The other lineages are more closely related and have diverged since the Middle Pleistocene. This study revealed an unexpected high level of genetic differentiation within L. neilli and highlighted the high endemicity of this species to limestone karsts. Our results enhance the importance of protecting limestone habitats to preserve not only the species but also intraspecific diversity.

Genus Lecithocera of Thailand (III): New Records of Five Species of the Genus (Lepidoptera,Lecithoceridae)

As the 3rd part of the taxonomic studies on the genus Lecithocera Herrich-Schäffer in Thailand, following after the previous two reports (Park, 2005a; Park, 2006), five species of the genus; Lecithocera aulias Meyrick, L. mylitacha Wu et Liu, L. metacausta Meyrick, L. pelomorpha Meyrick, and L. indigens (Meyrick), are reported for the first time from Thailand. In addition, the specific name squalida Gozmány, 1978, rev. stat. is resurrected from the synonym of L. aulias Meyrick.     

Two species of <Emphasis Type="Italic">Leptographium</Emphasis> isolated from blue-stained sapwood of <Emphasis Type="Italic">Pinus khasya</Emphasis> and bark beetles in Thailand

Two species of Leptographium were isolated from blue-stained sapwood of Pinus khasya and bark beetle galleries in pine trees near Chiang Mai, Thailand. Based on morphological observations, these two species were identified as L. pini-densiflorae and L. yunnanense. This is the first record of these fungi in Thailand. Leptographium yunnanense appeared to be associated with Polygraphus major.

A synopsis of Goniothalamus species (Annonaceae) in Thailand, with descriptions of three new species

A comprehensive taxonomic revision of Goniothalamus species (Annonaceae) occurring in Thailand is presented for the first time. Twenty-five species are recognized, including three that are described as new to science ( Goniothalamus aurantiacus from South-Western Thailand, Goniothalamus maewongensis from Northern Thailand, and Goniothalamus rongklanus from Northern and North-Eastern Thailand). Several taxonomic and nomenclatural misunderstandings are corrected. The name G. griffithii is shown to be widely misapplied for populations in Northern Thailand, for which the name G. calvicarpus should be applied; 'true' G. griffithii is restricted to South-Western Thailand and Myanmar. In addition, the widely used name G. marcanii is shown to be a synonym of G. tamirensis , and the name G. latestigma , previously regarded as a synonym of G. undulatus , is reinstated. Goniothalamus cheliensis is furthermore newly recorded from Thailand. Most species are restricted to Peninsular Thailand and represent a Malesian floristic component.  © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society , 2008, 156 , 355–384.
