Stypopodium Kütz. - a new generic record for India from the Bay of Bengal

Abstract

The study highlights the first-ever documentation of the genus Stypopodium along the Indian coastline, specifically in Andhra Pradesh. Previously reported in various Indian Ocean regions but not in India, this discovery fills a significant gap in understanding its distribution. The species Stypopodium zonale is thoroughly examined, including its physical characteristics, microscopic features, habitats, distribution, and taxonomic notes, complemented by accompanying photo plates. Additionally, the proposal of a lectotype for heterotypic synonyms, namely Fucus zonalis, Zonaria lobata, and Zonaria fuliginosa is presented.
