An annotated checklist and keys to the species of Copepoda Harpacticoida (Crustacea) Author Wells, J. B. J. text Zootaxa 2007 2007-08-31 1568 1 1 872 https://biotaxa.org/Zootaxa/article/view/zootaxa.1568.1.1 journal article 10.11646/zootaxa.1568.1.1 1175­5334 5096323 7F32B238-224A-4079-B0E0-D5003C7F185A Family Laophontidae Sexual dimorphism is highly developed in this family. Separate keys are given for males and females. Caution: P2–P4 setation is variable in many species. Variation is known to occur between populations, within a population, between the sexes and even between the right and left members of a pair of legs in a single individual. While these keys take present knowledge of variation into account, its very existence means that any identification must be checked against a good description.
