The Structure of the Anterior Feeding Apparatus in Members of the Ironidae (Nematoda : Enoplida)

  title={The Structure of the Anterior Feeding Apparatus in Members of the Ironidae (Nematoda : Enoplida)},
  author={A. van der Heiden},
The structure of the adult anterior feeding apparatus of Ironus, Thalassironus, Trissonchulus and Dolicholaimus is described, including hitherto unrecorded structures such as stomodeal pouches, protractors, retractors and tooth muscles. The existence of "hydrostatic tissue" is assumed. The feeding method of Ironidae was studied and the action of muscles associated with feeding was analysed. The unusual arrangement of the lips and position of the ventral gland orifice in the labial region of…

The Phanodermatidae were shown to be more closely related to the Enoplidae and Thoracostomopsidae than were the Leptosomatidae, suggesting that the buccal rods of the phanoderms (rather than the mandibular ridge/odontia complex of the Leptonchida), may be the origin of the mandibles.
Stoma and intestine ultrastructure of the marine free-living nematode Odontophora deconincki (Nematoda: Araeolaimida: Axonolaimidae)
The fine morphology of the buccal capsule and intestine of the marine free-living nematode Odontophora deconincki was investigated and it is assumed that the nematodes diet comprises a wide range of objects, mainly eukariotic epigrowth organisms, which are shorn off and scrapped from the surface of sand grains and then ingested.
Studies on Ironus Bastian, 1865 (Enoplida: Ironidae) from Iran with a comment on its phylogenetic position
During a survey on the soil nematodes from Kerman province, three species of Ironus, i.e., I. andamanus, I. elegans and I. ignavus, were isolated from natural areas in Kerman province (Iran).
Description of free-living marine nematodes found in the intestine of fishes from the Brazilian coast.
The combination of the fish feeding strategies and the poor preservation of the body of the nematode specimens found could indicate that these nematodes are pseudoparasites, appearing in the fishes' digestive tracts through accidental ingestion and thereafter surviving for brief periods of time.
Description of Ironus telperionensis n. sp. (Nematoda: Ironidae) and two known species of Chronogaster (Nematoda: Chronogastridae) and Paraphanolaimus (Nematoda: Aphanolaimidae) from the Telperion Nature Reserve (Mpumalanga, South Africa)
A new Ironus species is described as well as two known species reported for the first time from South Africa, viz., Chronogaster aspinata and Paraphanolaimus behningi, and the phylogenetic analysis revealed that Ironus is a monophyletic group.
Taxonomy and relationships of a new and the first continental species of Trissonchulus Cobb, 1920 along with two species of Ironus (Nematoda: Ironidae) collected from coal mines.
The morphological and taxonomic account of a new and the first terrestrial species of the largely marine genus Trissonchulus Cobb, 1920 is given, along with descriptions of two known species of the
Illustrated Key to the Genera of Free-Living Marine Nematodes of the Order Enoplida
A pictorial key to US genera of free-living marine nematodes in the order Enoplida is presented to facilitate identification of these organisms by nematologists and marine biologists working with meiofauna.
Morphological Characters and Methods for Preparing Nematodes
The purpose of this chapter is to review the methods used for the preparation of nematodes for identification, and to report results of the authors' own observations on the use of different methods.
