Classification of Tylenchida

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.

Unusual Malenchus Species (Nematoda: Tylenchidae)

Nematologica, 1986
Malenchus 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.

Evolution in Hoplolaims (Nematoda: Tylenchida)

Nematologica, 1990
Genera 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.

Some Remarkable Tylenchida From Korea

Nematologica, 1972
Four 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.

Tylenchida: parasites of plants and insects

2000
Tylenchida 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.

Tylenchidae From Buenos Aires, Argentina

Nematologica, 1996
Five 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.

The Structure of the Glandular Part of the Esophagus of Tylenchidae

Nematologica, 1971
The glandular part of the esophagus of tylenchids in which it is said to overlap the intestine differs from that of species having a glandular bulb in one or more of the following respects: ventral shift of the esophageal lumen to a position between the subventral glands, lateral shift of this lumen to a position between the dorsal and one subventral ...

Hoplolaimus Aberrans N.Sp. (Hoplolaiminae : Tylenchida)

Nematologica, 1959
L'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 ...

Four New Species of Tylenchidae (Nematoda)

Nematologica, 1985
Zanenchus nemorosus sp. n. from Poland differs from known species of this genus in its cuticle and lateral field, position of median oesophageal bulb, presence of post-uterine sac, and tail shape. Discotylenchus brevicaudatus sp. n. from Mexico is characterised by a short, thick tail and posterior position of vulva. Ottolenchus acris sp. n. from Poland

Dactylotylenchinae, a new subfamily (Tylenchidae: Nematoda)

Canadian Journal of Zoology, 1969
A 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
