The disadvantage ofsuch a system There have been a number ofkey taxonomic isthat, in penaeoids, often specimensofonly one papers on solenocerids in recent years by sexareavailable,orthespecimen isajuvenile. In Crosnier (1978, 1984, 1985, 1986, 1988, 1989, the Solenoceridae, however, the majority have 1994a,b) and byPerez Farfante (1977, 1981 and sufficient distinctive features of the cephalo- co-authored papers). Unfortunately, the thorax and abdomen, particularly the former, to literatureisratherscattered,ofteninpublications enable a positive identification to be made.
