- Abstract
Summary: Rotylenchus bunae n. sp. was discovered in the coffee rhizosphere in Gera district of Jimma, Ethiopia, and has been morphologically and molecularly characterised. The new species is identified by a female body length of 725-876 μ m, hemispherical lip region with 4-5 lip annuli, stylet length of 28-30 μ m, lateral field areolation only in the pharyngeal region, no cuticular striations, pharyngeal gland overlapping intestine dorsally by 15-26 μ m, double epiptygma, no clear spermathecae, vulva position at 54-58% of body length from anterior end, prominent fasciculi in mid and posterior body, rounded or sometimes slightly truncated, coarsely crenated tail with 11-13 annuli, and phasmids located at 7-16 annuli anterior to anus. No males were detected. This species was found closely related to other African Rotylenchus species, such as R. unisexus and R. wimbii ; however, it could be well separated from them by both morphology and molecular data (D2-D3 of 28S and partial 18S of rDNA).
