Overview
abstract
The new copepods were taken in inland marine caves. Erebonectes nesioticus is a calanoid and considered to belong to the Epacteriscidae and characterized by a 27-segmented 1st antenna of the female, essentially unmodified mouthparts and 3-segmented rami of all legs of both sexes, however, with strongly modified exopods of the 5th legs of the male. Paracyclopia naessi is a calanoid and belongs to the Pseudocyclopiidae and resembles Pseudocyclopia, but has 24-segmented 1st antennae of the female, a different setation of the endopods of the 1st legs, and simple uniramous 5th legs of the male. Antrisocopia prehensilis is a platycopiid with geniculate 1st antennae on both sides of the male, with both sexes having essentially similar 5th legs and 5-segmented urosomes. Platycopia and Antrisocopia are considered to represent a new order, the Platycopioida, separate from the Calanoida within the gymnoplean lineage. Antrisocopia and Erebonectes can be regarded as living fossils, and it is possible that specific caves serve as refugia for rare or less competitive species. 1985 Taylor and Francis Group, LLC.
