Types and type locality. The male holotype (13 mm; sample 62; MNHN) was collected from Dunedin, New Zealand by Captain Hutton from an unknown host ( Filhol 1885).

Remarks. Trilles (1973b) examined what he considered to be the holotype of Ceratothoa novaezelandiae , the specimen data corresponding with that in Filhol’s (1885) description. Trilles (1973b) stated that C. novaezelandiae was similar to C. trigonocephala and considered the species to be synonymous with C. trigonocephala . Hadfield et al. (2014a) mentioned that the identity of C. novaezelandiae could not be confirmed and the synonymy with C. trigonocephala was not upheld. Although the holotype of C. novaezelandiae was not examined, we consider that synonymy ( Trilles 1973b) with C. trigonocephala is open to question as the holotype is a male specimen. Ceratothoa novaezelandiae is therefore brought out of synonymy with C. trigonocephala and is here regarded as species inquirenda.

Hosts. Unknown.

Distribution. Dunedin, New Zealand ( Filhol 1885).
