On the Morphology of Aphelenchoides besseyi Christie, 1942 and A. siddiqii n.sp. (Nematoda, Aphelenchoidea)

Abstract

Aphelenchoides besseyi Christie, 1942 is recorded for the first time on rice in Mali and Upper Volta, the morphology is discussed and the description of the species emended. Boehmeria nivea Gaud. (Ramie) is reported as a new host for A. besseyi. A. siddiqii n.sp. is described from Foeniculum vulgare Mill, in Sudan. A key is given to the species of Aphelenchoides with a star tipped tail.

PM 7/39 (2) Aphelenchoides besseyi

“…Sanwal () produced a dichotomous key to the 35 Aphelenchoides species that were recognized at the time. Fortuner () devised a dichotomous key to 11 Aphelenchoides species with star‐shaped mucros. Baranovskaya () provided a dichotomous key to 97 species with descriptions of 105 species.…”

Aphelenchus assamensis sp. nov. (Nematoda: Aphelenchida: Aphelenchoidea: Aphelenchidae) from Assam, North East India

“…The morphometric differences of the present specimen from Aphelenchus avenae Bastian (1865) described by different authors are given in the table below (Table 2). Aphelenchus avenae (Bastian 1865) After Christie (1942) After Allen (1952) After Goodey and Hooper (1965) After Fortuner (1970…”

Aphelenchoides besseyi

“…Sanwal (1961) produced a dichotomous key to 35 Aphelenchoides species that were recognized at the time, but to date over 140 species have been described. Fortuner (1970) devised a dichotomous key to Aphelenchoides species with star‐shaped mucros, but the author considers this is no longer valid, because:…”
