Characterisation of some Scutellonema species (Tylenchida: Hoplolaimidae) occurring in Botswana, South Africa, Costa Rica and the USA, with description of S. clavicaudatum sp. n. and a molecular phylogeny of the genus
(Brill, 2017)The genus Scutellonema contains more than 40 species of spiral nematodes with enlarged phasmids called scutella. In this study, we provide morphological and molecular characterisation of S. clavicaudatum sp. n., S. ... -
Description of Acrobeles aenigmaticus sp. n. (Rhabditida: Cephalobidae), an unusual species with a poorly developed vulva, from the Kalahari Desert (Ngamiland, Botswana)
(Brill, 2019)Acrobeles aenigmaticus sp. n. is described from the North-West District (Ngamiland) of Botswana, which forms part of the Kalahari Desert. This new species is characterised by its body length, ‘double’ cuticle bearing ... -
Description of Calcaridorylaimus heynsi n. sp. (Nematoda: Dorylaimidae) from Potchefstroom, South Africa
(Brill, 2020)Calcaridorylaimus heynsi n. sp. is the second species of the genus to be described by both morphological and molecular techniques. Morphologically, it can be distinguished from all known species of Calcaridorylaimus by a ... -
Description of Globodera agulhasensis n. sp. (Nematoda: Heteroderidae) from South Africa
(Brill, 2017)A new cyst nematode, herein described as Globodera agulhasensis n. sp., was found parasitising Senecio burchelli in the Western Cape Province, South Africa. Second-stage juveniles are characterised by a well developed ... -
Description of Globodera sandveldensis n. sp. (Nematoda: Heteroderidae) from South Africa
(Brill, 2017)A new cyst nematode, herein described as Globodera sandveldensis n. sp., was found in the Sandveld, Western Cape Province, South Africa. As the host plant of G. sandveldensis n. sp. is currently unknown, the species is ... -
First record of Phasmarhabditis papillosa (Nematoda: Rhabditidae) in South Africa, and its virulence against the invasive slug, Deroceras panormitanum
(Brill, 2017)Worldwide interest in Phasmarhabditis originates from the successful commercialisation of P. hermaphrodita as a biological control agent against molluscs in Europe. To date, P. hermaphrodita has not been isolated from South ... -
Morphological and molecular characterisation of Aporcelaimellus nigeriensis sp. n. (Dorylaimida: Aporcelaimidae), a remarkable dorylaim from Nigeria
(Brill, 2020)A new species of Aporcelaimellus, collected in a watermelon field in Nigeria, is described, including its morphological and molecular (D2-D3 28S-rDNA, 18r-DNA) characterisation. Aporcelaimellus nigeriensis sp. n. is ... -
Morphological and molecular characterisation of one new and several known species of the reniform nematode, RotylenchulusLinford & Oliveira, 1940 (Hoplolaimidae: Rotylenchulinae), and a phylogeny of the genus
(Brill, 2016)The reniform nematodes of the genus Rotylenchulus are semi-endoparasites of numerous herbaceous and woody plant roots and are mainly distributed in tropical and subtropical regions. In this study, we provide morphological ... -
Morphological and molecular characterisation of two new Hemicycliophora species (Tylenchida: Hemicycliophoridae) with a revision of the taxonomic status of some known species and a phylogeny of the genus
(Brill, 2018)Hemicycliophora presently contains 132 valid species of sheath nematodes. Within several samples obtained from surveys in Canada, South Africa, Spain and the USA, we distinguished six valid and six putative unidentified ... -
On the morphology and phylogeny of Robustodorus Andrássy, 2007 and two ‘Aphelenchoides’ species (Nematoda: Aphelenchoidinae)
(Brill, 2018)In a survey of nematode damage in groundnut ( Arachis hypogaea ) (Fabaceae) production areas in the Vaalharts Irrigation Scheme in the Northern Cape Province of South Africa, a nematode was recovered and ...
