Trichotylenchus Falciformis N.G., N.SP. (Belonolaiminae N. Subfam.: Tylenchida Thorne, I949) An Associate of Grass Roots (Hyparrhenia Sp.) in Southern Tanganyika

Abstract

Trichotylenchus falciformis n.g. n.sp. is described, figured and put into the new subfamily Belonolaiminae. The spear base is split slightly, each arm bearing a rounded, basal knob. The head is cap-like with four lips, each with about four annules. The tail in both sexes is about six anal-body-widths long with the phasmids behind the mid-point of the tail. The lateral fields have three incisuresv the posterior part of the oesophagus overlaps the intestine as a glandular lobe. The ovaries are paired, outstretched and opposed; spermathecae are present; the vulva is median. The nematode occurred around roots of the grass Hyparrhenia sp. in Tanganyika. Belonolaimus is designated type genus of Belonolaiminae which is defined. J. B. Goodey.
