description
[2] Carriker (1963: 305) stated that the species here placed in the Ol. morionus species-group are “ very homogeneous and great care must be taken in evaluating their systematic status ”. This cannot be emphasized enough. Only Ol. clayae and Ol. violaceus are markedly different from Ol. nitzschi, and determination of other species must be approached with caution, a process made difficult by the vagueness of many of the original descriptions. It is possible that these lice all belong to the same euryxenous species, and ultimately many of these species may be synonymized. The material available to us is not sufficient to properly evaluate species limits in the group at this time. [3] The type host of this species was given by Carriker (1963) as “ Cyanocorax cyana (Linné) ”, while Price et al. (2003) listed the type host as Cyanopica cyana (Pallas, 1776). There is no such species as “ Cyanocorax cyana (Linné) ”, but there is a Cyanocorax cayanus (Linnaeus, 1766), which is widely distributed in Venezuela (Madge & Burn 1999), where the holotype was collected. In contrast, Cyanopica cyana is restricted to the Old World. The host name given by Carriker (1963) is most likely a misspelling, which lead to an erroneous interpretation of the host by Price et al. (2003). Therefore, we regard Cyanocorax cayanus as the type host of Ol. Cyaneus. [4] We tentatively accept this synonymy, following Price et al. (2003), but note that the issue is very complicated, and should be addressed more thoroughly in future work on this genus.
