- Аннотация: Siphonostomatoid copepods of the family Dirivultidae Humes, Dojiri, 1980 (Rimipontius mediospinifer Humes, 1996; Stygiopontius cladarus Humes, 1996; S. pectinatus Humes, 1987), known previously as benthic inhabitants of hydrothermal vents, were observed among subadult calanoids and planktonic poecilostomatoids (cf. Oncaea sp.) over a hydrothermal vent. They were collected along the Mid-Atlantic Ridge (Broken Spur, 29 degrees 10’ N, 43 degrees 10’ W) at a depth of 2660-2880 m using a slurp-gun mounted on the deep-sea submersible "Mir-1" in 1996 (September 4-8), Copepodid stages 1-5 were found in plankton among adult dirivultids and is the first report of early copepodid stages for dirivultids. Morphology of the copepodid stage 1 (Dirivultidae gen. sp,) is characterized by the presence of tergite on the somite with buds of leg 3, functional inclusion of this somite in the anterior part of the body, elongation of rami and armature in legs 1-2. On the basis of these findings and literary data one can conclude that development of subadult stages of these dirivultids occurs in plankton.
