Xiphinema costaricense n. sp. (Longidoridae, Nematoda) a new species of dagger nematode from Costa Rica

Abstract

An undescribed mono delphic species of the genus X iphinema Cobb was collected by the junior author in 1969 during a survey of plant parasitic nematodes in Costa Rica. The specimens were extracted from soil and root samples by a decantation-sugar flotation technique. They were killed by heat, fixed in 2-2.5 % formaldehyde, and transferred to glycerine by a rapid intermediate lactophenol method (Tarjan, 1973). The following description is based on adult females and juveniles.
