SUPERORDER THORACICA Although few new extant families have been suggested since 1982, there have been significant rearrangements of the cirripedes (or attempts to rearrange them) by workers using morphological and molecular data. Perhaps the most comprehensive is the cladistic study by Glenner et al. ’’ However, Glenner et al. (1995) also noted that ‘‘we have far to go Contributions in Science, Number 39 before a new taxonomy can emerge’’ and suggested the continued use of such commonly used terms as ‘‘lepadomorphs’’ or ‘‘pedunculates’’ as long as workers understand that these are groupings more of convenience than of common descent.

Papers describing new harpacticoid taxa (or elevating former subfamilies) include Huys (1990a, Adenopleurellidae; 1990b, Hamondiidae, Ambunguipedidae; 1990c, Cristacoxidae, Orthopsyllidae), Por (1986, Argestidae, Huntemanniidae, Paranannopidae [revised by Huys and Gee, 1996], Rhizothricidae [splitting the polyphyletic Cletodidae]), Fiers (1990, Cancrincolidae), Huys and Willems (1989, Laophontopsidae, Normanellidae; see also Huys and Lee, 1999), Huys and Iliffe (1998, Novocriniidae), Huys (1988, Rotundiclipeidae), Huys (1993, Styracothoracidae), and Huys (1997, Superornatiremidae).

The family Anomopsyllidae (included in Bowman and Abele, 1982, and in Huys and Boxshall, 1991) is not listed here. According to G. Boxshall (pers. ’’ Laubier (1988) (unfortunately overlooked by Huys and Boxshall, 1991) described both sexes of the genus and confirmed that it is a nereicolid. The family Vaigamidae proposed by Thatcher and Robertson (1984) also is not included here, as it was shown to be a synonym of the Ergasilidae by Amado et al. (1995). The Nucellicolidae, although retained for now, may prove to be a junior synonym of the Chitonophilidae (R.
