✦ Synopsis

To contribute to the biogeographical knowledge of rotifers, we critically re-evaluate the species of Lecanidae recorded from Thailand. We report on a number of rare (L. armata THOMASSON, L. bulla diabolica HAUER, L. chinesensis ZHUGE and KOSTE) and one new species of Lecane. Lecane latissima YAMAMOTO is recognized as the senior synonym of Lecane thailandensis SEGERS and SANOAMUANG, L. kostei DE RIDDER is reestablised as valid name for the cold-water bipolar taxon formerly referred to as L. latissima. Some dubious and dated records of taxa are reconsidered. In total, we confirm 92 species of Lecane from the country, which is almost half of the world's diversity of the taxon, and a limited degree of endemics to various scales, from countrywide to Paleotropical. These results are in accord with the moderate endemicity model of distribution and diversity patterns in microscopic organisms.

A potential new avenue of research may be to unravel cryptic diversity in species complexes such as the L. ludwigii, L. lunaris, L. bulla, L. leontina and L. quadridentata species groups as models of tropical and subtropical micrometazoans.

## Abstract Spironympha is discussed as valid genus. It was described by Koidzumi ('16); later it was redescribed by the same author as Microspironympha ('21). Therefore, according to the rules of nomenclature, it is Spironympha. The genus is compared with the related genera: Spirotrichonympha, Ho

## Abstract We here describe the new proalid rotifer species __Bryceella perpusilla__ n. sp. on the basis of light and electron microscopy. The species, certainly representing one of the smallest rotifer and even metazoan species at all, was obtained in January 2008 from terrestrial mosses of North

The ampharetid polychaete Alkmaria romijni (protected under the Wildlife and Countryside Act 1981) is recorded from a survey of intertidal mudflats on the south bank of the Humber Estuary (UK) in an apparently unusual habitat for the species. 2. The records from the Humber are considered together w
