Abstract

Three known and two new species of Aphanolaimus are described, viz. A. louisae, A. seshadrii, A. brasiliensis, A. aberrans sp. n. and A. vietnamicus sp. n. New data on the morphology and distribution of A. louisae, A. seshadrii and A. brasiliensis are given. The male of A. brasiliensis is described for the first time: it is characterised by the presence of one pair of neck setae, four tubular supplements, two precloacal and six caudal setae, 13-18 ¿m long spicules with oval manubrium and gradually narrowing shaft, platelike gubernaculum. Aphanolaimus aberrans sp. n. is characterised by a 495-681 ¿m long body, longitudinally striated cuticle, presence of 24-34 lateral epidermal glands, weakly sclerotised stoma, amphid with central elevation, lateral field starting on the third to seventh annule, oval ventral gland cell; female reproductive system with developed spermathecae, straight vagina without sclerotisations; male with one pair of neck setae, with two or three small tubular supplements and three or four caudal setae, 13-18 ¿m long spicules with oval manubrium and gradually narrowing shaft, plate-like gubernaculum. Aphanolaimus vietnamicus sp. n. is characterised by a 544-569 ¿m long body, longitudinally striated cuticle, presence of 19 lateral epidermal glands, weakly sclerotised stoma, amphid with central elevation, lateral field starting on 14th-18th annule, oval ventral gland cell; female reproductive system with developed spermathecae, straight vagina without sclerotisations; male with one pair of neck setae, with two tubular supplements and four caudal setae, 12 ¿m long spicules with oval manubrium and gradually narrowing shaft.
