The generic name Nordia (N. lepida Rozova, 1968, by original designation) was proposed by Rozova (1968: 108) for a new trilobite genus from the Upper Cambrian of the Tajmyr peninsula (NW Siberia, Krasnojarsk territory, Russian Federation).

FOUR NATIVE PLANT COMMUNITY TYPES (IN DECREASING ELEVATION: montane bog, rain forest, wet mesic forest, drier forest) on Molokai were sampled for nematodes. Six samples of 10 cores each were gathered from each community. Nematodes were extracted from 200 cm(3) soil by elutriation. All extracted nematodes were counted and identified to species-level taxa. Sixty-seven species were identified amon...

The taxonomy of the genus Aporcelaimellus is revised and updated. A new definition is proposed, with several remarkable diagnostic characters: cuticle three-layered, especially distinguishable at caudal region, usually bearing a hyaline space between inner and intermediate layers at terminal portion of tail; cervical lacunae often present and well developed; oral aperture a dorso-ventral, hexag...

Tylencholaimellus persicus sp. n. is described and illustrated based on morphological and molecular characters. The new species is characterized by its 613-885 μm long body, expanded lip region separated from body contour by a sharp constriction, forming a large disk-like structure, odontostyle and odontophore respectively 12-14 and 6.5-8.0 μm long, female genital system mono-opisthodelphic wit...
