Description of two known and one new species of the genus Anaplectus De Coninck & Schuurmans Stekhoven, 1933 (Nematoda: Plectida) from Europe, and a revised taxonomy of the genus

Two known and one new species of Anaplectus, viz. A. granulosus, A. atubulatus and A. brzeskii sp. n. are described from material collected in Poland, Ukraine and Sweden. A. granulosus is studied by SEM for the first time. A. brzeskii sp. n. is characterised by a body length of 863-1131 mum in females and 764-1056 mum in males, lip region slightly offset from body contour, amphid located at level with anterior part of stegostom, spinneret present, vulva located in a depression, female with four caudal setae, male with three midventral tubular supplements, spicules 40-48 mum long with oval manubrium wider than shaft, and gubernaculum 10-13 mum long, plate-like with a single strong caudal appendix. An emended generic diagnosis, a species list and identification key are provided

Occurrence of Ditylenchus destructor Thorne, 1945 on a sand dune of the Baltic Sea

Ditylenchus destructor is a serious pest of numerous economically important plants worldwide. The population of this nematode species was isolated from the root zone of Ammophila arenaria on a Baltic Sea sand dune. This population’s morphological and morphometrical characteristics corresponded to D. destructor data provided so far, except for the stylet knobs’ height (2.1–2.9 vs 1.3–1.8) and their arrangement (laterally vs slightly posteriorly sloping), the length of a hyaline part on the tail end (0.8–1.8 vs 1–2.9), the pharyngeal gland arrangement in relation to the intestine (dorsal or ventral vs dorsal, ventral or lateral) and the appearance of vulval lips (smooth vs annulated). Ribosomal DNA sequence analysis confirmed the identity of D. destructor from a coastal dune

New genus, three new and two known species of the family Onchulidae Andrassy, 1964 with notes on systematics and biology of the family

Tobrilonchulus novaezelandiae gen. n., sp. n. from New Zealand is particularly characterized by outer labial and cephalic sensilla arranged at the same level; stoma with one minute dorsal tooth, two ventrosublateral denticles and two drop-shaped sclerotizations; presence of gubernaculum; and long fl agelliform tail with caudal glands and spinneret. Tobriloides choii is redescribed on the basis of type specimens and fresh material collected in South Korea and China; particularly, new data are provided about the morphology of stoma and secretory-excretory system. Tobriloides camerunensis sp. n. from Cameroon is distinguished by shape of stoma, short cardia, number of supplements and tail shape. Onchulus fl agellatus sp. n. from Benin is distinguished by sexually dimorphic amphids, fi lamentous spermatozoa, supplements extending to the pharyngeal region and arranged in two sets, presence of gubernaculum, and short tail without caudal glands and spinneret. Limonchulus costaricanus sp. n. from Costa Rica is differentiated from other species of the genus by the presence of an organellum dorsale. Males of Stenonchulus troglodytes, described for the fi rst time, have spicules without distinct manubrium, with anteriorly directed projection and with arcuate conoid lamina; small and slender gubernaculum; and four midventral precloacal sensilla. Type specimens of Pseudonchulus inermis, Paronchulus straticauda and Onchulus fi licaudatus are redescribed. A cladistic analysis of 13 species representing seven genera of Onchulidae is provided on the base of published and updated morphological data. The genus Paronchulus is synonymised with Onchulus, the genus Pseudonchulus is synonymised with Kinonchulus, and Pseudonchulus inermis is synonymised with Kinonchulus sattleri

Nematodes associated with plant growth inhibition in the Wielkopolska region

The list of species of the plant parasitic nematodes presented in this paper (133 species belonging to 14 families) is based on the results of faunistic research conducted in the Wielkopolska region by Polish nematologists up until the year 2010, and the results obtained from the project “Elaboration of Innovative Methods for Rapid Identification of Nematodes Causing Damage to the Economy” managed by the Museum and Institute of Zoology of the Polish Academy of Sciences. During the two years of the project (2010-2011) we found 21 species of nematodes which had not yet been reported in the list of species from the Wielkopolska region. Two of them were reported for the first time in Poland
