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).

Swanson’s (1989a, b, 1990, 1991) discovery of living specimens of the primitive ostracode genus Manawa (family Punciidae) caused him to suggest the inclusion of ostracodes within the Maxillopoda as well. Cohen et al. (1998) note the following ‘‘perhaps homologous morphological characters’’: a medial naupliar eye that has three cups and a tapetal layer (present in most Myodocopida and in many Podocopida), and overall reduction in body size and limb number. However, other workers are quick to point out Rationale that reduction in body segmentation has occurred independently as a functional adaptation in many different and unrelated crustacean taxa and that the unique features of the Ostracoda argue for their recognition as a separate class (see especially discussions in Newman, 1992; Boxshall, 1992; Wilson, 1992).

VI. Nebaliadae’’ [sic] in his ‘‘Entomologist’s Useful Compendium,’’ which of course predates Baird’s (1850) work. Thus, we have attributed the family Nebaliidae to Samouelle, 1819. , Brusca and Brusca, 1990). , 2000). , Hof, 1998a, b; Hof and Schram, 1999). Schram (1971, 1986) had argued earlier for separate status of the hoplocarids as well. ’’ Their subsequent paper (Spears and Abele, 1999b) seems (to us) to indicate somewhat stronger evidence that hoplocarids are not eumalacostracans, but the authors are suitably cautious in not saying so.
