Hassalstrongylus musculi (Dikmans)

(= Longistriata musculi Dikmans )

Site of infection: Small intestine

Host: Mus musculus

Locality: Paraíso

Prevalence and mean intensity (range): 17.0% (27/159) and 23.9 (1–150)

Specimens deposited: MLP-He 7432 and CNHE 10711

Comments: The characteristics observed in our material agreed with those described by Dikmans (1935) of parasites from M. musculus , and the re-description by Durette-Desset (1974) of parasites from the same host, i.e. 24 cuticular ridges in the synlophe at midbody; slightly disymmetrical bursa with right lobe larger than left, with pattern of type 1-3-1; rays 8 stout and longer than the dorsal ray; dorsal ray divided in its second third; spicules 400–441 long with typical foot shaped tips; and absent gubernaculum.

In México, H. musculi has been recorded from Oligoryzomys fulvescens (Saussure) O. couesi , and O. melanotis in San Luis Potosí (Underwood et al. 1986). This is the first record of H. musculi from its type host ( M. musculus ) in this country.
