New records of Criconematidae (Nemata) from Ethiopia

Abstract

Sporadic surveys over the past twenty years in different areas of Ethiopia have shown several associations between plant-parasitic nematode genera and various crops; however, taxonomic studies of the nematodes of Ethiopia are almost non-existent. During a survey in the 2002 cropping season in the south, west and southwestern parts of this country, seven Criconematidae species were found of which all are new records for the country except P. leptos Raski, 1975. The species found are C. crassianulatum (de Guiran, 1963) Raski & Luc, 1985, Criconema mutabile (Taylor, 1936) Raski & Luc, 1985, Criconemoides goodeyi de Guiran, 1963, Discocriconemella limitanea (Luc, 1959) De Grisse & Loof, 1965, Ogma decalineatum (Chitwood, 1957) Andr.ssy, 1979, Paratylenchus leptos Raski, 1975 and P. pandatus (Raski, 1976) Siddiqi, 1986. Short notes, discussions and illustrations are given for five well-known species viz. C. crassianulatum, C. mutabile, D. limitanea, O. decalineatum and P. leptos. Two males of P. leptos were found for the first time and are described. The lesser known C. goodeyi and P. pandatus, which has only been found for the second time now, are described and illustrated in more detail.
