摘要:

Marine microdrile oligochaetes are described for the first time from Eastern Australia, occurring in the sub‐littoral zone beneath coral clumps on the sand flat and shallow lagoon of Heron and Wistari reefs. A population density of 20,000 worms/m3, or 2/100 cm5, is estimated for Heron Reef.Clitellio arenicolus queenslandicussubsp. nov. has proportionately smaller atria than the nominate subspecies from Naples and North America. Synonymy ofC. subtilisPierantoni with this species is questioned.Limnodriloides winckelmanniMichaelsen is described for the first time since its description for South‐west African material butL. barnardiCook, from Baja California, is regarded as a junior synonym. The genusPhallodrilusis redefined to includeTorodrilus lowryiCook,Rhyacodrilus prostatusKnollner and two new species,P. albidusandP. rohdei,and a key to the twelve species ofPhallodrilusis given.Grania macrochaeta trichaetasubsp. nov. (Enchytraeidae) is added to the three subspecies ofG. macrochaetarecently recogni

摘要:

Six species ofHypselodorisand three species ofChromodoris axedescribed from the coast of East Africa. Three species ofHypselodorisand one species ofChromodorisare new species. Two species ofChromodorisfrom the tropical West Pacific are also described. The eleven species fall into three groups of similarly coloured species.Hypselodoris nigrostriataand a new species ofHypselodorisare compared withH. infucata, H. festiva, H. obscuraand two unnamed species from the literature. It is concluded that all these are distinct species.H. nigrolineataand two new species, are compared withH. lineataandH. hilarisand all are considered distinct.H. regina, Chromodoris quadricolor, C. africana, C. elisabethina, C. magnifiedand a new species ofChromodoris,are compared withC. westraliensisand two unnamed species from the literature. All these species are considered distinct.All other names for forms falling into these three colour groups are considered synonyms of one or other of the above named species. Full synonymies are given.
