Three new species of Pontellopsis (Copepoda, Calanoida) from Indonesian waters, with notes on their species-groups

Abstract

Abstract Three new species of Pontellopsis from Indonesian waters are herein described. Pontellopsis celebensis n. sp. is distinguishable by its very elongate Ur1 armed with a pair of anterolateral setules and the symmetrical P5 in the female; the right posterior corner of Pdg5 modified into a long, sickle-like process in the male. Pontellopsis bispinata n. sp. is characterized by a pair of anterolateral setules on Ur1 and the form of P5 in the female; the right posterior corner of Pdg5 is modified into a long, straight, sword-like process in the male. Pontellopsis rajaensis n. sp. is described from female specimens only. It is distinguished by having the posterior corners of Pdg5 modified into rounded lobes and the form of P5. The establishment of five new species-groups of Pontellopsis, i.e., the P. herdmani-group, the P. macronyx-group, the P. pexa-group, the P. regalis-group, and the P. scotti-group, and in addition species as yet unassigned to groups, is here proposed.
