Zool. Soc. Lond., 1926: 289 . Type Locality: Namibia , NW Ovamboland, Ukualukasi, 3400 ft. ( 1100 m ). Vernacular Names: Shortridge's Free-tailed Bat . Distribution: S Dem. Rep. Congo , Angola , Namibia , Botswana , Zimbabwe , Zambia . Conservation: IUCN 2003 – Not evaluated; not considered in IUCN / SSC Action Plan (2001). Discussion: plicatus species group. Often considered a subspecies of chapini , but see Peterson et al. (1995) , who treated these taxa as distinct species based on significant size differences and the large geographic gap apparently separating the southern populations ( shortridgei ) from northern populations ( chapini ). Fenton and Eger (2002) included shortridgei in chapini with no comment. Based on my own limited observations, I prefer to treat chapini and shortridgei as distinct species pending additional data.
