Type host. Phocarctos hookeri (Gray, 1844) — New Zealand sea lion.
Type locality. Auckland Islands, New Zealand.
Type specimen/s data. Syntypes Ƥ probably lost (Enderlein 1906: 665; Kim et al. 1986: 46). There is no information about their original deposition.
Other hosts. Family Otariidae—Sea lions: Neophoca cinerea (Péron, 1816) —Australian sea lion; Zalophus californianus (Lesson, 1828) —California sea lion; Zalophus wollebaeki Silvertsen, 1953 —Galápagos sea lion; Otaria flavescens (Shaw, 1800) —Southern American sea lion; Eumetopias jubatus (Schreber, 1776) —Northern sea lion.
Geographic distribution. Palearctic, Nearctic, Neotropical and Australasian Regions.
Significant references. Enderlein (1909: 508, description, figures of both sexes); Freund (1928: 21, detailed figures); Ferris (1934: 489, synonymy, description, figures, hosts); Webb (1946: 95, spiracle structure); Ferris (1951: 75, synonymy, hosts, notes); Kim et al.

Remarks. A. microchir probably represents a complex of morphologically indistinguishable cryptic species. Leonardi et al. (2009, 2012a) compared specimens with reference material from the New Zealand, Australian, Steller and Californian sea lions, without finding morphological differences. Ferris (1934: 498) reported as “ Antarctophthirus sp.” a fragmentary specimen collected from an Arctocephalus sp. without locality data which, according to him, had scales of the type present on A. microchir but more elongate.
