The latter name is derived from the subgenus <jats:italic>Brevimulticaecum<\/jats:italic> Mozgovoy, in Skrjabin, Shikhobalova, and Mozgovoy, 1951 by raising it to generic rank and emending the definition. <jats:italic>Multicaecum<\/jats:italic> contains a single species, <jats:italic>agile<\/jats:italic> Wedl, 1861 occurring in <jats:italic>Crocodylus<\/jats:italic> spp. in Africa, India and Australia, and is characterized by smooth rounded lips, each with a dentigerous ridge comprising small sharp denticles. The excretory pore is level with the nerve ring or behind it, and the ventricular appendices are long and slender. The species <jats:italic>gangeticum<\/jats:italic> Maplestone 1930 and <jats:italic>quadrata<\/jats:italic> Linstow 1904 are excluded from <jats:italic>Multicaecum<\/jats:italic> and regarded as species <jats:italic>inquirendae incertae sedis. Brevimulticaecum<\/jats:italic> contains five species occurring in the caimans and the alligator of the New World: <jats:italic>baylisi<\/jats:italic> Travassos, 1933 (type species; <jats:italic>acuticauda<\/jats:italic> Schuurmans-Stekhoven, 1937 is placed in synonomy under <jats:italic>baylisi<\/jats:italic>); <jats:italic>stekhoveni<\/jats:italic> Baylis, 1947; <jats:italic>tenuicolle<\/jats:italic> Rudolphi, 1819; and two new species. <jats:italic>Brevimulticaecum<\/jats:italic> spp. are characterized by flat lips with alate margins and notches, without dentigerous ridges, excretory pore in front of or at nerve ring and the ventriculus with short appendices. The significance of this proposal is discussed in relation to the other genera of ascaridoid nematodes in crocodilians.<\/jats:p>","DOI":"10.1017\/s0022149x00005782","type":"journal-article","created":{"date-parts":[[2009,6,5]],"date-time":"2009-06-05T15:35:46Z","timestamp":1244216146000},"page":"91-116","source":"Crossref","is-referenced-by-count":27,"title":["Ascaridoid nematodes of amphibians and reptiles: <i>Multicaecum<\/i> and <i>Brevimulticaecum<\/i>"],"prefix":"10.1017","volume":"53","author":[{"given":"J.
