Basirolaimus gen. n. (Nematoda: Hoplolaimidae) with the description of Basirolaimus sacchari, n. sp. from India

Abstract

There are species of Hoplolaimus which differ from the type species, H. tylenchiformis Daday, 1905, in possessing six nuclei in the oesophageal glandular lobe instead of three nuclei as in the type species and in others related to it. The number of these nuclei in Hoplolaimus spp. is considered to be of diagnostic value at generic level. Consequently, a new genus, Basirolaimus, is proposed for those species with six nuclei. A new species, B. saccharis, is described.
