Polygonatum Miller (1754, without pagination) (Asparagaceae) is a relatively large genus containing approximately 60 taxa (Chen & Tamura 2000). The majority of species are eastern Asian (Jeffrey 1980, Chen & Tamura 2000). Phyllotaxy, cytology, and filament morphology have been recognized as important in delimiting species (Suomalainen 1947, Tamura 1990, 1991, 1993). Specimens of an anomalous Polygonatum collected by J.F. Maxwell from northern Thailand, Doi Inthanon have a general affinity to P. punctatum Royle ex Kunth (1850: 142) and have been reported as that species (Tamura 1993, Maxwell 1998), but differ in their emaculate white and longitudinally ridged perigone. Cultivated material from the same locality (BSWJ6599, Figs. 1–2) provides clear observation of the differences that are not as apparent on pressed specimens. It differs in several morphological features from P. punctatum: stem characters; phyllotaxy; leaf shape; inflorescence type and position; perigone color; and filament size, orientation, and morphology. The combined morphological differences and non-contiguous distributions of P. costatum in comparison to P. punctatum support its recognition as a new species, thus far documented only from the highest elevation in northern Thailand.

Ferulago akpulatii (Apiaceae) is described as a new species endemic to Central Anatolia, Turkey. It is closely related to Ferulago platycarpa and F. pauciradiata, and is easily distinguished by its cauline leaf shape, inflorescence type, and fruit features. The main morphological differences between Ferulago akpulatii and related taxa are discussed, and the diagnostic characteristics, including the anatomical features of fruits, are given in detail. An identification key of Ferulago akpulatii and the morphologically closer species is also provided.

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.

Memecylon wayanadense Ratheesh, Sivu & Pradeep, a new species of Melastomataceae from the Wayanad forests of Kerala, India, is described and illustrated. The new species is allied to Memecylon angustifolium, M. rivulare and M. sivadasanii but differs in habit, leaf shape, sclereid type, inflorescence type and position, and the shape and size of the sepals and petals. An UPGMA analysis of 20 RAPD primers resulted in two major clusters with Memecylon sivadasanii in one cluster and M. rivulare, M. angustifolium and M. wayanadense in the second cluster. Memecylon wayanadense forms a subgroup within the second cluster.

Phyllagathis impressinervia (Melastomataceae, Sonerileae), a new species from northwestern Guangxi, China and previously misidentified as P. cavaleriei in Chinese herbaria, is illustrated and described. The new species closely resembles P. cavaleriei in leaf shape, inflorescence type, and morphology of stamens and capsule, but can be easily distinguished by the leaf veins strongly sunken adaxially, hypanthium pubescent with ca. 1 mm long, spreading glandular hairs, creamy white anthers, and conspicuous ovary crown at anthesis.

A new species of tracheline spiders, Utivarachna rama Chami-Kranon & Likhitrakarn sp. n., is described. The types were collected from pristine forests of the Doi Inthanon National Park, Chiang Mai Province, northern Thailand. The new species belongs to the kinabaluensis-group and can be distinguished from its congeners by the gradually tapering retrolateral tibial apophysis of the male palp, and by the posteriorly rounded epigynal atrium, the reniform spermathecae, and the anterior bursae with long, narrow necks in females. Utivarachna rama sp. n. is closely related to U. bucculenta Deeleman-Reinhold, 2001 and U. kinabaluensis Deeleman-Reinhold, 2001.

During a survey of the sub-Antarctic diatom flora, several populations previously identified as Fragilaria alpestris were reanalysed and compared with type material of the latter species. The morphological ultrastructure of the type of F. alpestris, the sub-Antarctic populations and an additional population of F. cf. alpestris from Spitsbergen has been analysed using light and scanning electron microscopy observations. The analysis revealed that Fragilaria alpestris clearly belongs to the genus Fragilaria whereas the sub-Antarctic populations show all morphological features of the genus Staurosira. Comparison with similar taxa worldwide showed that these populations belonged to an unknown taxon that could not be identified using the currently available literature. A new species, Staurosira vandenbusscheana Van de Vijver sp. nov. is therefore described. The F. cf. alpestris population from Spitsbergen forms long, ribbon-like colonies, unlike the type of F. alpestris that never produces band-like colonies. Following the observation of additional morphological differences such as the presence of two rimoportulae and the shape of the linking spines, the Spitsbergen taxon is described as a new species: Fragilaria confusa sp. nov. The three taxa described herein share a number of morphological features. Their specific features are detailed below along with notes on their ecology. A literature survey and an analysis of the records for F. alpestris are given.

As a first step towards an inventory of the giant pill-millipedes in Thailand, a new species of the genus SphaerobelumVerhoeff, 1924, S. truncatum n. sp. is described from Nan Province, northern Thailand. A determination key is presentedfor all five known Sphaerobelum species. Clear morphological differences between S. truncatum n. sp. and the other fourSphaerobelum species were found on the anterior telopods. For the first time in Sphaerobelum, the partial mitochondrialCOI gene was sequenced for S. truncatum n. sp. and compared with distance, maximum parsimony and maximum likeli-hood methods to those of species from other giant pill-millipede genera. Sphaerobelum truncatum n. sp. was found to dif-fer from all other analyzed giant pill-millipedes, including species of Zephronia Gray, 1832, by 22–30%, includingnumerous amino acid changes, supporting the separate status of Sphaerobelum among other giant pill-millipede genera.Maximum likelihood and parsimony analyses support the placement of Sphaerobelum in the Zephroniidae. Figures of allrelevant structures of Sphaerobelum truncatum n. sp. are provided to allow the use of these characters in future descriptions of species of the family Zephroniidae.

Formerly Cnemidophorus was thought to be the most speciose genus of Teiidae. This genus comprised four morphological groups that were later defined as four different genera, Ameivula, Aurivela, Cnemidophorus and Contomastix. The last appears as paraphyletic in a recent phylogenetic reconstruction based on morphology, but monophyletic in a reconstruction using molecular characters. Six species are allocated to Contomastix. One of them, C. lacertoides, having an extensive and disjunct geographic distribution in Argentina, Uruguay and Brazil. Preliminary analyses revealed morphological differences among its populations, suggesting that it is actually a complex of species. Here, we describe a new species corresponding to the Argentinian populations hitherto regarded as C. lacertoides, by integrating morphological and molecular evidence. Furthermore, we demonstrate that the presence of notched proximal margin of the tongue is a character that defines the genus Contomastix.

Abstract A new species of micromorphic articulate brachiopod (Rhynchonellida) Lambdarina jugowiensis sp. nov., from the upper Visean (Sokolec Beds) of central Sudetes, SW Poland, is described. The studied specimens are calcified, what makes them unique in respect of their state of preservation. The material is represented by a full range of growth stages; from brephic to gerontic. Based on its morphological features and the palaeogeographical distribution of all its known species, two main evolutionary lines are proposed for the genus; the Australian and the European ones. Lambdarina was widely distributed in the equatorial-tropical waters of marginal seas of the Palaeotethys Ocean, mostly during Mississippian time.
