Some actinolaimid nematode species belonging to the genera Egtitus Thorne, 1967 and Trachypleurosum Andrassy, 1959 are described or redescribed from Costa Rica. Egtitus costaricae sp. nov. is distinguished from the related spe- cies, E. biformis Andrassy, 2012, E. neocyatholaimus (Kreis, 1936) and E. proximus (Yeates, 1973), by the wide lip region (21- 23 vs 15-17 µm) and the low number of the male supplements (6-8 vs 9-13). The Costa Rican specimens of Trachypleurosum venezolanum Coomans…

Three New Species of Actinolaim Nematodes From India

Three new species of Actinolaimidae are described, two belonging to Paract inolaimus Meyl, 1957, and one to Westindicus Thorne, 1967, which differs in having longer female tail, shorter spicules and fewer ventromedian supplements.

Freeliving nematodes from nature reserves in Costa Rica. 1. Dorylaimina

The first results of a study of dorylaims found in nature reserves in Costa Rica show the great interest of the nematofauna of these reserves and the subfamily Paraxonchiinae and the position of the genus Gopalus are discussed.

Two new species of Eucephalobus Steiner, 1936 and one new species of Pseudacrobeles Steiner, 1938 (Rhabditida: Cephalobidae) with mucronate tail

Two new species of Eucephalobus and one new species of Pseudacrobeles (Pseudacrobeles) are described from studies by light and scanning electron microscope. Eucephalobus iaculocaudatus sp. n. was

Study of the type specimens of Trachypleurosum confonne (Schneider, 1935) showed that they possess four large onchia in the buccal cavity, Consequently the genus differs from Trachactinolaimus only in the absence of denticles on the cheilostome wall.
