25. Amblyomma cohaerens Dönitz, 1909 .

An Afrotropical species whose adults are usually found on Artiodactyla : Bovidae ; immature stages have been collected from Mammalia (several orders), Galliformes : Numididae and Phasianidae , and Passeriformes : Turdidae . Amblyomma cohaerens is a very rare parasite of humans.

Redescriptions

M: Robinson (1926), Hoogstraal (1956a), Elbl and Anastos (1966a), Matthysse and Colbo (1987), Voltzit and Keirans (2003)

F: Hoogstraal (1956a), Elbl and Anastos (1966a), Matthysse and Colbo (1987), Voltzit and Keirans (2003)

L: Voltzit and Keirans (2003)

Note: Amblyomma cohaerens appears to be rather difficult to identify because there are several claims of confusion with congeners in Hoogstraal (1956a), Elbl and Anastos (1966a), Walker (1974), Keirans (1985c), Matthysse and Colbo (1987) and Uilenberg et al. (2013), among others, raising uncertainties about the descriptions and redescriptions listed above, with the exception of the original description. Additionally, these redescriptions lack uniformity and precision. Voltzit and Keirans (2003), for example, claim that Elbl and Anastos (1966a) and, tacitly, Borght-Elbl (1977), confused Amblyomma astrion with Amblyomma cohaerens , but the redescription of the female scutum in Voltzit and Keirans (2003) differs in terms of the pattern of punctations when compared with Robinson (1926). Moreover, Voltzit and Keirans (2003) state that the dentition of the nymphal hypostome of Amblyomma cohaerens is 2/2, but their figure shows a 3/3 dental formula. It would be worthwhile to further study the external morphology of Amblyomma cohaerens , with support from molecular taxonomy.
