First Description of the Immature Stages and Redescription of the Adults of <I>Cosmiomma hippopotamensis</I> (Acari: Ixodidae) With Notes on Its Bionomics

“…Original description based on female (as I. bimaculatus ) from Southern Africa and male (as I. hippopotamensis ) from South Africa (Denny, 1843). Santos Dias (1958) found three males, one of which is the type of I. hippopotamensis, and six females, one of which is the type for I. bimaculatus, in the Natural History Museum (NHM) (London).…”

“…Ixodes bimaculatus Denny, 1843; Ixodes hippopotamensis Denny, 1843; Amblyomma hippopotami (Denny, 1843) Koch, 1844; Amblyomma hippopotamense (Denny, 1843) Neumann, 1899; Hyalomma hippopotamense (Denny, 1843) Neumann, 1906; Dermacentor ( Cosmiomma ) hippopotamensis (Denny, 1843) Hoogstraal, 1956; Cosmiomma bimaculatum (Denny, 1843) Santos Dias, 1958.…”

“… Cosmiomma hippopotamensis (Denny, 1843) is one of the most unusual, beautiful, and rare tick species known to the world. All stages of this species possess a unique morphology, on the one hand making them easy to identify, while on the other they exhibit similarities to certain species of Amblyomma Koch, 1844, Dermacentor Koch, 1844, and Hyalomma Koch, 1844.…”

“…Cosmiomma hippopotamensis (Denny, 1843) is one of the most striking, but rarely collected, species of African ixodid ticks. In 1970, however, a locality in north–west Namibia, at which it was fairly abundant, was discovered, and numerous adult specimens were collected from the vegetation (Bezuidenhout and Schneider 1972).…”

“…The male and female were originally described as separate species of the genus Ixodes Latreille, 1796; initially the female as Ixodes bimaculatus Denny, 1843 and thereafter the male as Ixodes hippopotamensis Denny, 1843. A year later Koch (1844) realized that I. bimaculatus and I. hippopotamensis are sexes of the same species.…”
