Seven species of
Chromodoris and one of
Hypselodoris are described from collections from the Indo-West Pacific. Of the species of
Chromodoris, two are from Fiji, two are from the Gulf of Kutch in north-western India, one being a new species, and three are from the coast of East Africa.
Hypselodoris infucata is described from both the Gulf of Kutch and Zanzibar.
C. youngbleuthi and
C. inopinata are compared with published accounts of five other species with red reticulate markings (
C. tinctoria, C. alderi, C. reticulata, C. obsoleta and
Risbecia reticulata) and it is suggested that apart from
C. alderi, which is considered a junior synonym of
C. tinctoria, all these species are distinct.
C. inornata Pease, which has often been confused with other forms with red or purple spots, is compared with published information on eight other species (
C. petechialis, C. daphne, C. festiva (Angas),
C. splendida, C. tenuis, C. tumulifera, C. splendens and
C. inornata Gohar & Soliman). It is suggested that all these forms are distinct and that
C. inornata Gohar & Soliman, which is distinct from
C. inornata Pease, should take the name
Chromodoris dollfusi Pruvot-Fol 1933
