Neoheligmonella gracilis ( Baylis, 1928)

(= Heligmonella gracilis, Baylis, 1928 )

The type-material is made up of four males and one female parasitic in one Mus (Nannomys) musculoides ( Leggada musculoides on the label) n° 411 from Ibadan ( Nigeria). In Baylis’ description the spicules are 230– 280 µm long. In the type-material, three males (slides 105, 106, 108) have spicules long of 280, 290, 285 µm long, respectively. Therefore we consider these specimens as belonging to Neoheligmonella gracilis . The spicules of the fourth male (slide 107) are 710 µm long. This specimen is 2.7 mm long and 100 µm wide at mid-body, the ratio SpL/BL is 25.3% versus 9–10.7% in the type specimens. It belongs therefore to another species which is a coparasite with N. gracilis but the data concerning this specimen are insufficient to identify it at level of the genus. It is only possible to say that it is a member of the Nippostrongylinae .
