Haemaphysalis hoodi Warburton and Nuttall 1909
No full text59. Haemaphysalis hoodi Warburton and Nuttall, 1909. An Afrotropical species, all of whose parasitic stages are usually found on Aves (several orders). There are occasional records of adults and immature stages from Artiodactyla: Bovidae, Primates: Indriidae, and Rodentia: Sciuridae; adult ticks alone have sometimes been recovered from Carnivora: Canidae, Lagomorpha: Leporidae, and Rodentia: Hystricidae; immature stages have been found on Carnivora: Viverridae. Haemaphysalis hoodi is a very rare parasite of humans.

A new twist on the Nuttall function Q<sub>m,n</sub>(a,b)
No full textNew expressions for the Nuttall function (Formula presented.) are given in terms of the confluent Appell function (Formula presented.). The derived closed-form expressions are valid for integer values of m and n satisfying (Formula presented.) with (Formula presented.) being an odd integer; this happens to be the case of many practical applications involving the Nuttall Q-function.</p
Ixodes cavipalpus Nuttall and Warburton 1908
No full text42. Ixodes cavipalpus Nuttall and Warburton, 1908. An Afrotropical species whose adults are usually found on Artiodactyla: Bovidae. All parasitic stages occur on Bovidae; adults alone have occasionally been collected from other Mammalia (several orders) (Guglielmone et al. 2014, Horak et al. 2018). Ixodes cavipalpus is a very rare parasite of humans.

(1975b) Note: Nuttall and Warburton (1911) constructed an identification key where the male of Ixodes cavipalpus is said to have no spurs on coxa I, but it is described as having one spur in the text, and the latter description is the correct one. Guglielmone et al. (2014) state that records of Ixodes cavipalpus based on specimens collected outside the Afrotropical Region require confirmation.Published as part of Guglielmone, Alberto A., Petney, Trevor N. & Robbins, Richard G., 2020, Ixodidae (Acari: Ixodoidea): descriptions and redescriptions of all known species from 1758 to December 31, 2019, pp. 1-322 in Zootaxa 4871 (1) on page 18, DOI: 10.11646/zootaxa.4871.1.1, http://zenodo.org/record/442334

Ixodes victoriensis Nuttall 1916
No full text249. Ixodes victoriensis Nuttall, 1916. An Australasian species, all of whose parasitic stages have been found on Diprotodontia: Potoroidae and Vombatidae (Guglielmone et al. 2014, Weaver 2016). There are no records of Ixodes victoriensis causing human parasitism.

Rhipicephalus simpsoni Nuttall 1910

An Afrotropical species, all of whose parasitic stages are usually found on Rodentia: Thryonomyidae; adults and nymphs have been collected from Rodentia: Hystricidae, while adult ticks have been recovered from Mammalia (several orders). There are no records of Rhipicephalus simpsoni causing human parasitism. M: Nuttall (1910) F: Nuttall (1910) N: Clifford and Anastos (1964); see note below L: Walker et al.

(2000) L: none Note: Santos Dias (1951b) described the nymph and redescribed the male and female of Rhipicephalus simpsoni. However, the nymph in Santos Dias (1951b) differs morphologically from the nymphs of Rhipicephalus simpsoni in Clifford and Anastos (1964) and Walker et al. (2000) with respect to the spurring of coxae II-III, and we therefore have provisionally excluded the description and redescriptions of Rhipicephalus simpsoni in Santos Dias (1951b) from the above lists.Published as part of Guglielmone, Alberto A., Petney, Trevor N. & Robbins, Richard G., 2020, Ixodidae (Acari: Ixodoidea): descriptions and redescriptions of all known species from 1758 to December 31, 2019, pp. 1-322 in Zootaxa 4871 (1) on pages 237-238, DOI: 10.11646/zootaxa.4871.1.1, http://zenodo.org/record/442334

No full text91. Ixodes gibbosus Nuttall, 1916. A Palearctic species whose adults are usually found on Artiodactyla: Bovidae, but all parasitic stages have been collected from Bovidae, and Perissodactyla: Equidae. Adult ticks alone have been recovered from Artiodactyla: Camelidae, Carnivora: Canidae, Erinaceomorpha: Erinaceidae, Lagomorpha: Leporidae, and Aves (unknown orders); nymphs alone have been found on Passeriformes: Turdidae (Guglielmone et al. 2014, Maurelli et al. 2018).
