On a New Species of Oxysomatium Railliet and Henry, 1913 and Some Notes on the GeneraOxysomatium andAplectana

Abstract

The cuticle is smooth. The lateral alae extend from the middle of the oesophagus to the region of the spicules in the males, but in females they are extended further posterior to the middle of the tail or more. The anterior short "pharynx", the procorpus, is poorly differentiated from the remaining cylindrical portion of the oesophagus. Three sclerotized structures are present at the anterior end of the oesophagus. The posterior flaps of the valves of the bulb extend slightly into the dilated lumen of the intestine. The intestine at its commencement is broader than the bulb, and gradually narrows down towards the anus. The excretory pore is situated anterior to the usual pre-bulbar position, and is located at the beginning of the posterior third of the cylindrical oesophagus. It is surrounded by a crown of chitinous rod-like structures. The tail is sharply pointed in both sexes.

Nématodes parasites de Caméléons malgaches

“…sp., en hommage amical au Professeur R. Legendre, à qui nous devons la découverte de cette espèce. Bien que rejeté dans certains ouvrages modernes, ce genre a été admis par beaucoup des auteurs qui se sont intéressés au groupe (et, en particulier, Walton, 1940 ;Ballesteros, 1945, et Fotedar, 1960.…”

Some Parasitic Nematodes from the Cameroons (W. Africa)

“…In view of these facts the generic diagnosis for Neoraillietnema Ballesteros Marquez, 1945 does not appear to be sufficient and therefore it is regarded as a synonym of Oxysomatium and 0. punctatum Walton, 1933 is transferred from Neyraplectana Ballesteros Marquez, 1945 to its original genus. Fotedar (1960), while discussing accurately the synonymy of Oxysomatium and Aplectana, remarked that Ballesteros Marquez (1945) "proposed new generic names such as Neyraplectana for Aplectana and Neoxysomatium for Oxysomatium." This seems to be (5)…”
