	abstract = {This article begins with a critical review of the article of Lamberti et al. (1992) with descriptions of X. brevicollum, X. diffusum, and three new species (X. parvum, X. pseudoguirani, X. taylori), all closely related to each other. After studying type specimens of these five species and paratypes of X. incognitum and X. sheri, the present authors propose X. diffusum, X. incognitum, X, parvum, X. pseudoguirani, X. sheri, and X, taylori as junior synonyms of X. brevicollum. The second part of the article includes a detailed characterization of the Xiphinema americanum-group and a list of its species. X. pachydermum, X. brevisicum, X. longistilum, X. mesostilum, and X, microstilum are excluded from the X. americanum-group. (C) Orstom/Elsevier, Paris.},

The ultrastructure of the cuticle was mostly similar to recent observations on four species from western Africa. Some intraspecific differences were seen in the thickness of layers 4 and 6. The ultrastructure of the body cuticle in the region of the retracted spicules in I? pachydermus is clearly different from that in T. primitivus. This result confirms the diagnostic value of presence vs absence of caudal alae for differentiating the didelphic genera. (C) Orstom/Elsevier, Paris.},

Additional information is provided on Xiphidorus minor, Xiphinema surinamense, and X. krugi. The reproductive system (structure of the uteri) of Argentinean females of X, surinamense was somewhat different from earlier descriptions: in the posterior branch, the proximal part of the uterus is well differentiated from a narrower strongly developed muscular median uterus filled with spiniform crystalloid structures; in the anterior branch, the uterus is long, glandular, and not clearly differentiated.

The gene product of a first gene, Hs-eng1, consists of several domains: it starts with a secretion signal, followed by a catalytic domain which is linked to a cellulose binding domain. The second protein encoded by Hs-eng2 lacks the cellulose binding domain. The genes have high homology to the endoglucanase genes of other nematodes and resemble also those of bacteriol endoglucanases.},

The sphincter between oviduct and uterus has a sinuous lumen and {\textquoteright}internal musculature{\textquoteright}.
