Three species of fungi that attack microscopic animals are described as new. Verticillium coronatum (Hyphomycetes) produces conidia that have a cluster of small, apical appendages. The appendages function in attaching the conidia to the cuticle of the host nematode in the initial stages of infection. Diheterospora humicola (Hyphomycetes) was found to attack bdelloid rotifers in soil. Infection of the host is initiated by ingestion of conidia. Lagenidium oviparasiticum (Oomycetes) is an aggressive parasite of the eggs of Adineta rotifers. Zoospores of the fungus encyst on the egg shell, penetrate, and transfer their contents into the egg to initiate infection.

The list of tardigrade species recorded from Belarus is provided; nine were new records for this geographic area and three,Macrobiotus sottilei sp. nov., Paramacrobiotus klymenki sp. nov. and Hypsibius valentinae sp. nov. were new to science.Macrobiotus sottilei sp. nov. had smooth cuticle; eye spots present; the dorsal transverse ridges of the buccal armaturejoined to form a continuous arc; pharyngeal bulb with two macroplacoids and microplacoid; eggs with processes in shapeof inverted goblets with indented distal discs; egg shell with a very dense reticular design.Paramacrobiotus klymenki sp. nov. had smooth cuticle; eye spots absent; buccal armature similar to that of P. areolatus;buccal tube not very wide; stylet supports inserted on the buccal tube at about 80% of its length; pharyngeal bulb withthree macroplacoids; microplacoid absent; eggs with conical processes with a reticular design similar to that of P. areola-tus; egg shell areolated; central area of each areola slightly thickened but not subdivided.Hypsibius valentinae sp. nov. had smooth cuticle; eye spots present; buccal tube very narrow; pharyngeal bulb with twomacroplacoids and a small septulum, claws of the Hypsibius type; small, smooth, flexible lunules present; a short cuticular bar is present between the bases of the claws of the hind legs; no cuticular bar on the first three pairs of legs.

Only few species of tardigrades have been recorded from Israel. In this paper we report an additional 20 species, 18 of which are new records for that geographical area; four (Bryodelphax meronensis sp. nov., Macrobiotus dimentmani sp. nov., Pseudobiotus hirsutellus sp. nov. and Mixibius schnurae sp. nov.) are new to science. Bryodelphax meronensis sp. nov. differs from similar species (B. alzirae, B. tatrensis and B. mateusi) in details of the cuticular ornamentation and the absence of papilla on the hind legs. It also differs from B. alzirae by the presence of 12 lateral intersegmental platelets, instead of 6. It differs from B. atlantis in details of the plate ornamentation, lack of eyes, and shorter internal buccal cirri. Macrobiotus dimentmani sp. nov. differs from M. diffusus with more slender claws, the external claws slightly longer, and in characteristics of the eggs (the apical portion of the conical processes is subdivided into two to six long, flexible terminal points that are not very thin filaments; each process has a ring of basal dots, the egg shell has an obvious granulation). Mixibius schnurae sp. nov. differs from all other known species within the genus by characteristics of the cuticular ornamentation; in addition it differs from M. ornatus and M. sutirae in having the stylet supports inserted on the buccal tube in a more cephalic position; and from M. ninguidus in having longer buccal tube and shorter second placoid. Pseudobiotus hirsutellus sp. nov. differs from P. vladimiri in the presence of eye spots; cuticular spine-shaped processes present on the central portion of the body as well as the anterior and posterior portions; wider buccal tube, longer placoids; longer claws that are without accessory points; and the absence of oval papillae on the first three pairs of legs. The new species differs from P. spinifer in having less numerous and smaller spine-shaped cuticular processes; wider buccal tube; longer placoids; and the absence of oval papilla on the first three pairs of legs.

Fifteen moss samples collected in the Sophia Province (Bulgaria) were examined. In these samples six eutardigrade species were found: Hypsibius convergens, Isohypsibius prosostomus, Macrobiotus binieki sp. nov., M. hufelandi, M. pallarii and Ramazzottius oberhaeuseri. The new species belongs to the Macrobiotus harmsworthi group and differs from the most similar M. australis, M. coronatus, M. patiens, M. pseudocoronatus, M. radiatus, M. rigidus and M. simulans mainly by: egg processes covered by small bubbles (not smooth or reticulated), egg shell between processes covered by wrinkles not dots or stripes forming a large radiate crown, a higher number of processes on egg circumference and some morphometric characters of adults. In this paper a key to all species of the harmsworthi group is also given.

Biological Value

AbstractKristianstads Vattenrike Biosphere Reserve [KVBR] is a UNESCO designated area of Sweden possessing high biological value. Although several studies on tardigrades inhabiting Sweden have been performed, the KVBR area has been neglected. The current study investigates the tardigrade fauna of five areas of the biosphere reserve and includes 34 samples of different substrates analysed quantitatively and qualitatively. In total, 33 species of tardigrades were found in the samples, including 22 new records for the Skåne region, 15 new records for Sweden, and four species new to science. Mesobiotus emiliae sp. nov., Xerobiotus gretae sp. nov., Itaquascon magnussoni sp. nov., and Thulinius gustavi sp. nov. were described with an integrative approach (when possible) using morphological characters (light, electron scanning, and confocal laser scanning microscopies) and molecular markers (ITS2, 18S, 28S, cox1). A new protocol to increase morphological data was developed recovering mounted specimens within old slides for SEM analysis. Emended diagnoses for the genus Itaquascon and the transfer of Platicrista itaquasconoide to the genus Meplitumen are proposed. This study enriches the knowledge of the tardigrade biodiversity both within the KVBR and in Sweden and contributes to the rapidly increasing number of tardigrade species reported worldwide. The 33 species identified in the KVBR area represents 28% of all water bear species found in Sweden so far. The restricted study areas and limited number of samples collected suggests that the KVBR is very rich of tardigrades.
