Аннотация:Within the family Archaeobalanidae, the sponge-inhabiting barnacles include species in the subfamily Acastinae and the genus Membranobalanus in Archaeobalaninae in Balanomorpha and they are obligatory symbionts of poriferans, alcyonaceans and antipatharians. The subfamily Bryozobiinae composed of species that live in sponges. Previous studies on the diversity and distribution of sponge inhabiting barnacles in the West Pacific are fragmented and the species Acasta sulcata Darwin, 1854 was being recorded through the whole Indo-Pacific region by morphological approach only. Using a combined morphological and molecular approach, recent collections of sponge barnacles in Taiwan and Australia have revealed high diversity of sponge-inhabiting barnacles and four new species which are morphologically close to Acasta sulcata and belong to a proposed ‘sulcata species complex’. The new species include Acasta aspera sp. nov., Acasta huangi sp. nov., Acasta radenta sp. nov. and Acasta undulaterga sp. nov., and are described here in.
