[Description of Spirobakerus weitzeli n. g., n. sp., and remarks on the Nematodes Spirocercidae (author's transl)].
Description of Spirobakerus weitzeli n. g., n. sp., parasitic in a Cricetidae of Columbia and revision of the Neotropical Spirocercidae. The taxa Leiuris vazipereirai (Lopez-Neyra, 1951) n. comb. and Texicospirura cesticellus (Molin, 1860) n. comb. are proposed. The endemic neotropical Spirocercidae include: --Four paleoendemic genera: Didelphonema in marsupials, Leiuris in the Bradypodidae, Tejeraia in Caviomorphs and tapirs, and Spirobakerus in the Cricetidae (which in interpreted as an example of the capture phenomenon). Given the conspicuous development and anterior location of the median cephalic formations, these four genera are considered as the most primitive Spirocercidae in the world fauna. --Two recently endemic forms: Texicospirura in peccarries and Physocephalus lassancei in cervids. Their more evolved morphological characters seem to indicate a much later introduction into the Netropical zone.
