New Records and Descriptions of Plant Nematodes From Rain Forest Soil in French Guiana, With a First Description of Males of Mesocriconema Surinamense (De Grisse & Maas, 1970) Loof & De Grisse, 1989 (Tylenchida: Nemata)

Abstract

Redescriptions are given for Mesocriconema surinamense (De Grisse & Maas, 1970) Loof & De Grisse, 1989, associated with Dicorynia guianensis Amshoff and Rotylenchus caudaphasmidius Sher, 1965 associated with a species of Aspidosperma Martius & Zuccharini in a French Guiana rain forest. These are new records for that country. Males of M. surinamense are described for the first time and are characterized by a squared labial disc and a comparatively small bursa. Discocriconemella heynsi Van den Berg & Marais, 1995 is proposed as a synonym of M. surinamense. Discocriconemella limitanea (Luc, 1959) De Grisse & Loof, 1965 is reported from soil around D. guianensis.
