Abstract
    Prior to the present revision the taxon Labidodemas comprised Labidodemas americanum, L. pertinax, L. rugosum and L. semperianum. An up-to-date re-evaluation of the group proved that at least four additional species need to be assigned to it. Three of these are new to science: one has recently been discovered in the shallow-waters of KwaZulu-Natal, Republic of South Africa; one originates from Low Island, Australia and was erroneously identified as L. semperianum and one sterns from South-West Sulawesi, again erroneously identified as L. semperianum. In addition, Holothuria maccullochi, classified in the monotypic subgenus lrenothuria, and Holothuria proceraspina are assigned to Labidodemas; the former as a valid species and the latter as a synonym of L. semperianum. Annotated taxonomic descriptions, distribution maps and an identification key are given.The new observation that L. americanum holds Cuvierian tubules suggests that its rank remains at generic level rather than at family level as was recently proposed.
