Molecular Phylogeny of Malenchus and Filenchus (Nematoda: Tylenchidae)
The family Tylenchidae is phylogenetically important to understanding early-branching Tylenchomorpha and to assess soil ecosystems. In this study, we focus on Malenchus and Filenchus as representatives of the Tylenchidae.

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.

1988
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.

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.

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.

Tylenchida: parasites of plants and insects
2000Tylenchida are the largest and most important group of plant-parasitic nematodes. They cause severe crop losses, particularly in the tropics, but even in Europe and North America where chemical control has been used for many years, keeping nematode populations at a reasonable level is proving increasingly difficult.

Hoplolaimus Aberrans N.Sp. (Hoplolaiminae : Tylenchida)
Nematologica, 1959L'auteur donne une description de Hoplolaimus aberrans n.sp. La nouvelle espece se distingue si nettement des autres especes du genre, que l'auteur s'est base sur un seul exemplaire, une femelle, pour la decrire. Footnote : The author has recently made a morphological study of adults of Scutellonema bradys (Steiner & Le Hew, 1933) Andrassy, 1958 upon ...

Dactylotylenchinae, a new subfamily (Tylenchidae: Nematoda)
Canadian Journal of Zoology, 1969A new species of Dactylotylenchus, D. filiformis, was described and more information for D. crassacuticulus Wu, 1968 was presented. The thick cuticle and the digitate sclerotized labial framework of this genus provide the unique character for Dactylotylenchus in the family Tylenchidae. A new subfamily Dactylotylenchinae was created to accommodate this

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 ...

A New Species of Telotylenchus (Nematoda: Tylenchida)
Nematologica, 1963A new species of the genus Telotylenchus Siddiqi, 1960 is described, viz. T. ventralis, occurring in a cereal field in the Netherlands. Its chief distinguishing character is the peculiar ventral thickening of the cuticle just anterior to the vulva, followed by a contraction of the body.
