Interpretive Summary: Nematodes are microscopic worms that live in the soil. Some cause crop diseases of $100 billion annually; others feeding on fungi or other microorganisms are beneficial to agriculture. One major agricultural problem is that the species of nematode genera are difficult to identify particularly of the free-living nematode genera in the order Dorylaimida, Plectida, Mononchida, and Rhabditida. In this study, ARS scientists from Beltsville, Maryland, in collaboration with a retired colleague from the Indian Agricultural Research Institute, New Delhi, India, described ten new species including two new genera of nematodes based on major characteristics that were illustrated anatomically with a light microscope. The research team also discovered how to distinguish anatomically these different groups of nematodes from closely related genera. The results are significant because description of these new genera and species makes the accurate identification of nematodes possible and represents the first report of these new genera and species isolated from vegetable and fruit crops of the Jammu and Kashmir state. Therefore, this research will be used by research scientists, action agencies, and extension personnel involved in nematode research and control and will serve as a useful guide to researchers and diagnosticians identifying important nematodes from the various nematode genera.

Technical Abstract: During a survey conducted from 1973-1977 by the senior author (ZH) of soil and plant-parasitic nematodes of vegetable and fruit crops of Kashmir valley, Jammu and Kashmir, ten new species including two new genera of nematodes were recovered: Fotedaronema kashmiriensis gen. et. sp. nov. from soil around roots of Pyrus communis from Sonamarg, Kashmir; Kochinema pahalgamiensis sp. nov. from soil around roots of Brassica oleraceae from Pahalgam, Kashmir; Kochinema kanganiensis sp. nov. from soil around roots of Lycopersicum esculentum, in Kangan, Kashmir; Parasicagutter chitwoodi gen. et. sp. nov. from soil around roots of Pyrus malus in Pattan, Kashmir; Tylencholaimellus brassicus sp. nov. from the roots of Brassica oleraceae var. capitata in Pulwama, Kashmir; Tylencholaimus orientalis sp. nov. from soil around roots of Glycine max, in Handwara, Kashmir, Longidorus goldeni sp. nov. from soil around roots of Prunus persica in Sopore, Kashmir; Mylonchulus shamimi sp. nov. from soil around roots of Pyrus communis L. from Sonamarg, Kashmir; Chronogaster anantnagiensis sp. nov. from soil around roots of Pyrus malus L. in Anantnag, Kashmir and Chronogaster mustafaensis sp. nov. from soil around roots of Juglans regia in Tral, Kashmir. Morphological and morphometric details, line drawings along with description, characteristics, and relationships of each new genus and species with its closely related genera and species are given.
