Additional morphometrical data on some heligmonellidae (Nematoda: Trichostrongylina) parasitic in neotropical rodents (Cricetidae)

Abstract

Some additional morphological and metrical data are provided, particularly on the synlophe of the following species: Hassalstrongylus dessefae Pinto, 1978, Stilestrongylus eta (Truvussos, 1937), Stilestrongylus manni Denke & Murúu, 1977 and Stilestrongylus valdivianus Durette-Desset & Murúu, 1979, bused on type und voucher mutend deposited in Bruzlliun and French collections. Heligmonoides crassidorsualis Franco, 1967 is considered as a Nippostrongylinae incertae sedis: its synlophe not being known it is impossible to report the species to o given genus. However, it is unlikely that the species belong to the genus Heligmonoldes Baylis, 1928, present only In commensol Murinue from the Old World. Heligmonoides mlrzal Smales, 2009, is also regurded, temporarily, as u Nippostrongylinae incertae sedis.
