Type host: “In the gape of the penguin” (Maskell 1885: 20) = Eudyptes pachyrhynchus G.R. Gray, 1845
Remarks. Dumbleton (1953: 24) lists Eudyptes pachyrhynchus as the host of the ticks described by Maskell and collected by A. Reischek at Dusky Sound, Fiordland. However, Reischek (1885: 194) only mentions “… an insect similar to the Membranacea inside the edges of the bill, …”. The taxon “Membranaceae” is listed by Stark (1828: 320) as a “Tribe” within the Hemiptera containing the bedbug genus Cimex Linnaeus, 1758 only. Although ticks and bedbugs are very different animals, their broad morphological and feeding similarities would justify Reischek’s (1885) identification. Although we have not been able to examine any tick from E. pachyrhynchus, other than the types, we accept the designation of this penguin species as the type host. Interestingly, Reischek (1885: 194) also records Eudyptula minor (J.R. Forster, 1781) from Dusky Sound, the type locality of I. eudyptidis, but without mentioning any external parasite.
Material examined. Type specimens: Three syntype females (Reg. 2015.162.10; 2015.162.12–13) and six syntype nymphs (Reg. 2015.162.11; 2015.162.14–18), from Eudyptes pachyrhynchus (see above), held in the collection of the Canterbury Museum, Christchurch, New Zealand [CMNZ].
Although Dumbleton (1953: 12) wrote: “Maskell's type material (2 females and 7 nymphs) is in the Canterbury Museum, as is one female co-type and a nymph determined by Nuttall.”, i.e. 11 specimens in total, we have located only nine specimens (3 females and 6 nymphs) and we do not know the whereabouts of the two missing nymphs.
Designation of a lectotype: Considering that we have identified and described a species morphologically close to I. eudyptidis, with the type series of the latter composed of syntype females and nymphs, we deemed it advisable to designate a lectotype to make the identification of I. eudyptidis unequivocal.
Therefore, we hereby designate one female syntype, with Registration Number 2015.162.10 as the lectotype of I. eudyptidis. All other syntypes: two females and six nymphs with Registration Numbers 2015.162.11–18 become paralectotypes. All types are held in the collection of the CMNZ.
