Neoheligmonella impudica ( Baylis, 1928)

(= Heligmonella impudica Baylis, 1928 ) ( Tables 5, 7, 8, Figures 22–24 )

The type material is made up of three males and one female parasitic in one Gerbilliscus (Taterona) kempi ( Taterona kempi on the label) n° 404 from Ibadan, Nigeria. Baylis identified this species in three other G. (T.) kempi (n° 387, nº 455, nº 467), two Arvicanthis rufinus ( Arvicanthis mordax on the label) (n° 505 and nº 508) from Kano, one Arvicanthis rufinus (n° 445) from Ibadan and six Lemniscomys striatus , four (n° 57, nº 258, nº 286, nº 329) from Adu, one (n° 477) from Oyo and another one (nº 80) without indication of geographic origin. In his description, Baylis mixed the data concerning the type material and the voucher material. The spicules of the syntype males measure 300, 380 long with a ratio SpL/BL of 6.25, 9.7%. The single syntype female has a rounded and very thick tail. From these data we have attempted to identify the voucher material.
