Superfamily CRYPTONISCOIDEA Kossmann, 1880
Introduction
Cryptoniscoids are ectoparasitic on other crustaceans (copepods, ostracods, isopods, amphipods, barnacles, and mysids) and host species have been the basis of division of the group into numerous families (Nielsen & Strömberg 1965, 1973). This taxonomic division has little support from morphological differences between the so-called families and genera (Caroli 1953; Nielsen & Strömberg 1965). Sars (1898), Kensley (1978) and Schultz (1969) have used the family name Cryptoniscidae Kossmann, 1880 in its broadest sense, treating families such as Cabiropidae Giard & Bonnier, 1887 as junior synonyms. Martin & Davis (2000) however listed seven families in this superfamily whereas Trilles' (1999) 'Section des Cryptoniscina' of superfamily Bopyroidea listed eight. Only one family, Cabiropidae, is represented in Australia although its species have sometimes been referred to Cryptoniscidae.
The Cryptoniscoidea are generally thought of as one of the two superfamilies of Epicaridea, a suborder sunk into the Cymothoida in this Catalogue.
After some discussion, Grygier & Bowman (1991) decided the authorship of the family Cryptoniscidae, and thereby the superfamily. Grygier (1993) reviewed further the nomenclatural history of the family.
Diagnosis
Female: Sac-like, with few distinct somites. Pereopods absent. Oostegites absent, brooding internally. Male: Mature during second larval stage (cryptoniscus). Antenna 1 with lamellar basal article, often serrated. Oral cone simple, without a sucker, directed anteriorly or posteriorly. Pereopods 3–7 slender, with setiform dactyli, coxal plates serrated. Pleopods biramous, well developed. Uropod with exopod much shorter than endopod.
