Its Sequence Analysis

This paper is the second in a series of biodiversity papers on Lactarius subgenus Russularia in tropical forests of Southeast Asia. This study is based on extensive mycological exploration, especially in Northern Thailand, during the past ten years. In this paper we consider some species that are characterized by remarkably small basidiocarps i.e. with an average pileus diameter that is smaller than 20 mm. One of the most common species in Northern Thailand with dwarf basidiocarps is L. gracilis, originally described from Japan. We introduce the new species L. crenulatulus, L. perparvus and L. glabrigracilis with morphological descriptions and illustrations. Molecular evidence based on the ITS sequence analysis supports the classification and novel status of the taxa. All species are associated with trees belonging to the Fagaceae. These are the first reported collections of small basidiocarps of L. subg. Russularia in Southeast Asia. In our paper we compare these new species with small basidiocarp with similar representatives from Europe and other Asian regions.

Abstract A new species of miniature fish of the characid genus Priocharax is described from a small lake near the rio Ipixuna, rio Purus drainage, Amazonas State, Brazil. It is distinguished from all congeners except P. pygmaeus by the lower number of teeth on the maxilla and dentary. It differs from P. pygmaeus by the presence of two postcleithra and 22–27 branched anal-fin rays (vs absence and 19–22). The new species is further distinguished from other species of Priocharax by a combination of characters involving the number of pelvic-fin rays and branched anal-fin rays, the number of postcleithra, the shape of postcleithrum 3, and the absence of the claustrum. Molecular evidence based on COI sequences of all valid species of Priocharax also corroborates the validity of this new species.

Two New Species

We describe two new species of green pitviper from Southeast Asia that are morphologically similar to Cryptelytrops macrops, but can be distinguished from that species by genetic means, multivariate analysis of morphology and some aspects of coloration. Cryptelytrops cardamomensis sp. nov., is described from southeastern Thailand and the Cardamom Mountains of southwestern Cambodia. Cryptelytrops rubeus sp. nov. has been recorded from southern Vietnam and eastern Cambodia. These species have previously been confused with C. macrops, hence we also present here a redescription of this species, whose range is now restricted to Thailand, southern and central Laos, and northeastern Cambodia. All three species are present in Cambodia, but have disjunct ranges corresponding to three separate highland regions in southwestern (Cardamom Mountains), northeastern (western edge of the Kontum Plateau) and eastern (low elevation hills on the western edge of the Langbian Plateau) Cambodia for C. cardamomensis, C. macrops and C. rubeus respectively. However, there is still considerable morphological variation between geographically separated populations of C. macrops s.s., and greater sampling in southern and northern Thailand in particular may be required before the species diversity of this group is fully clarified.

A new species of the funnel-web spiders from Thailand, Allagelena monticola sp. n., is described and illustrated. The types of this species were collected from remnant patches of pristine evergreen hill forest in the Doi Inthanon National Park, Chiang Mai Province, northern Thailand. The new species resembles the widely distributed species A. opulenta (L. Koch), which is known from China, Korea and Japan. This discovery expands the known zoogeographical distribution of the genus Allagelena southwards into tropical Southeast Asia.

A New Species

Homonotais a gecko distributed in central and southern South America with 12 species allocated in three groups. In this work, we performed molecular and morphological analyses of samples ofHomonotafrom the central region of northern Paraguay, comparing the data with those of related species of the group:H.horridaandH.septentrionalis. We found strong molecular evidence (based on 16S, Cyt-b, and PRLR gene sequences) to distinguish this lineage as a new species. Morphological statistical analysis showed that females of the three species are different in metric characters (SVL and TL as the most contributing variables), whereas males are less differentiated. No robust differences were found in meristic characters. The most remarkable trait for the diagnosis of the new species is the presence of well-developed keeled tubercles on the sides of the neck, and lack of a white band (crescent-shaped) in the occipital area, which is present inH.horridaandH.septentrionalis. Nevertheless, in our sample, we found three specimens (one juvenile and two young adults) that exhibit the white occipital band. Thus, this character seems only reliable in adults of the new species. The new species is parapatric toH.septentrionalis, both inhabiting the Dry Chaco of Paraguay.

Neisseria meningitidis is one of the principal sources of bacterial meningitis worldwide and can as well cause sepsis, pneumonia, and further expressions. In states with elevated widespread rates, the illness load puts a huge tension on the public health structure. The universal epidemiology of persistent meningococcal disease (IMD) diverges distinctly by area and in due course. This appraisal summarizes the burden of IMD in diverse states and recognizes the highest-incidence countries where habitual preventive programs aligned with Neisseria meningitidis would be essentially profitable in offering security. Accessible epidemiological figures from the past 20 years in World Health Organization and European Centre for Disease Prevention and Control assortments and available articles are comprised in this review, in addition to straight statements with important specialists in the area. The nations were clustered into high-, moderate-, and low-occurrence states. The mainstream of countries in the elevated-occurrence set are located in the African meningitis belt; several reasonable-occurrence states are located in the European and African areas, and Australia, whereas low-occurrence countries comprise numerous from Europe and the Americas. Precedence nations for vaccine involvement are high- and restrained-incidence nations where vaccine-avoidable serogroups prevail. Epidemiological records on burden of IMD are required in nations where this is not distinguished, predominantly in South- East Asia and Eastern Mediterranean areas, so evidence-based assessments concerning the application of meningococcal vaccines can be created.

A New Species

Xanthagaricus siamensis, a new species in the family Agaricaceae, was discovered in northern Thailand and is here introduced based on its morphological features and molecular data. It is characterized by small to medium-sized basidiomata, a convex to plano-convex with depressed center pileus when mature, the presence of greyish orange to violet-brown fibrillose squamules on the pileus, lamellae that start out white, change to pinkish white when damaged, then change to dull green with age. Additionally, the annulus is fugacious, and the pileipellis is recognized as a cutis which morphologically distinguishes it from all other known Xanthagaricus. Phylogenetic analysis of the internal transcribed spacer region (ITS) and the large subunit of the nuclear ribosomal DNA (nrLSU) sequence data indicated that the three specimens of X. siamensis form a distinct lineage within Xanthagaricus, and they formed a well-supported clade representing the genus Xanthagaricus. Detailed illustrations of macro- and micro-morphological characteristics and descriptions are provided, as well as other relevant molecular evidence.

A new cave-dwelling species of Cyrtodactylus Gray is described from Mae Hong Son Province in northern Thailand. The new species, C. erythrops sp. nov., is characterized by its moderate size (snout-vent length to at least 78 mm), relatively large, closely-spaced, flattened tubercles in 18–20 irregular rows at midbody, low number of ventral scales across midbody (28), absence of precloacal groove, presence of precloacal and femoral pores separated by a diastema, broad subcaudal plates, and dorsal pattern of dark spots and blotches. It is the fifth species of cave-dwelling Cyrtodactylus recorded from Thailand and its discovery adds to the mounting evidence that this genus exhibits unprecedented levels of localized endemism throughout tropical Southeast Asia.

A New Species

Odontochilus Blume (1859: 79) comprises about 40 species distributed from the Himalayas and China through Southeast Asia eastwards to the southwestern Pacific islands (Chen et al. 2009, Pearce & Cribb 2002, Pridgeon et al. 2003). Most species are restricted to tropical and warm-temperate regions. The genus is closely related with Anoectochilus Blume (1825: 411) and most of species were in the past included in that genus because both genera have flowers with pectinate or dentate (rarely smooth) lip flanges. However, Odontochilus is separated from Anoectochilus based on the saccate non-exerted spur that is largely enclosed by the bases of the lateral sepals, whereas Anoectochilus has an exerted conical or cylindrical spur (Pridgeon et al. 2003).

A New Species

AbstractA new species of Cuora, Cuora chiangmuanensis sp. nov., is described on the basis of a nearly complete shell with limb bones from the late Middle – early Late Miocene Chiang Muan Mine, Phayao Province (Northern Thailand). C. chiangmuanensis is distinguished from other fossil and living Cuora species mainly on the basis of its plastral morphology. Among fossil and extant Cuora taxa, the new species appears to be a missing link between the taxa from Southeast Asia and those from East Asia. It represents the earliest record of the genus and demonstrates that by 11–12 Ma, Asian box turtles were already present in Southeast Asia.
