Unusual Malenchus Species (Nematoda: Tylenchidae)
Nematologica, 1986Malenchus williamsi n. sp. is exceptional among Malenchus spp. because of the six lines in its lateral field, long vulval flaps and a post-vulval phasmid. M. parthenogeneticus sp. n. and M. leiodermis sp. n. are also exceptional by having four lines in the lateral field and parthenogenetic reproduction: no males, no spermatheca developed.

Phasmids in Tylenchulidae (Tylenchida: Criconematoidea)
Nematology, 2005AbstractLight-microscope studies revealed the presence of phasmids in the mid-tail region in species of the genera Tylenchulus, Trophotylenchulus (syn. Trophonema), Sphaeronema and Meloidoderita in Tylenchulidae. Scanning electron microscopy studies on Sphaeronema species verified these observations.

Some Remarkable Tylenchida From Korea
Nematologica, 1972Four species of Tylenchida from Korea are discussed: Hemicriconemoides varionodus n. sp. is characterized by rounded stylet knobs, 102-112 body annules, continuous rounded lip region and conical tail. A second population of Merlinius koreanus contained males with a variable bursa structure; one of them showed a tail resembling that of the female.

Tylenchidae From Buenos Aires, Argentina
Nematologica, 1996Five species belonging to the genus Filenchus, including a new species and one species of Coslenchus were found in soil samples collected from natural grassland in Argentina. Other samples were collected from a fallow field previously cultivated with potatoes. Scanning electron micrographs are presented for F. dittisimus, F. facultativus, F. baloghi, F.

Globodera presently contains 13 valid and three as yet undescribed species. Three species, G. rostochiensis, G. pallida and G. ellingtonae, the potato cyst nematodes (PCN), cause significant economic losses on potatoes around the world.

Living organisms undergo a continuous change, as do their physical surroundings. Some changes in animals appear in a short time, others could take thousands of years to show. Comparative studies of animals are based on these changes occurring through time and are governed by the philosophy of organic evolution.

Hoplolaimus Angustalatus N.Sp. (Hoplolaiminae: Tylenchida)
Nematologica, 1959L'auteur donne une description de Hoplolaimus angustalatus n. sp., parasite des racines des bananiers. Cette espece differe des autres especes de ce genre par la possession de membranes laterales rudimentaires, une excroissance situee entre la lunule du bulbe median et la region posterieure oesophagienne, la division des 3 anneaux basaux de la tete en ...

Evolution in Hoplolaims (Nematoda: Tylenchida)
Nematologica, 1990Genera that show a transitional series are difficult to define: the series discussed is Rotylenchus - Scutellonema - Peltamigratus - Aorolaimus - Hoplolaimus. Two hypotheses are presented. First the evolutionary development of this series is associated with the theory of continental drift.
