Two New Species of Pachycara Zugmayer (Teleostei: Zoarcidae) from the Indian Ocean, with Redescription of Pachycara shcherbachevi Anderson
During the multidiciplinary BIGSET (Biogeochemische Stoff- und Energietransporte in der Tiefsee/Biogeochemical Transport of Matter and Energy in the Deep Sea) programme 1995 and 1998 in the abyssal Arabian Sea, 33 specimens of Pachycara Zugmayer, 1911 were collected. Until then, a single trawl-damaged specimen of Pachycara shcherbachevi Anderson, 1989, caught in 1951 by the Danish research vessel Galathea, represented the only evidence of lycodine eelpouts in the Indian Ocean. One of the newly caught specimens belongs to P. shcherbachevi and provides the basis of a revised description of the species. The rest of the material belong to two different species, which are described here as new.Abstract
