Zeacarpa leiomorphais a crustose brown alga endemic to South Africa. The species has been tentatively placed in Ralfsiaceae, but its ordinal assignment has been uncertain. The molecular phylogeny of brown algae based on concatenated DNA sequences of seven chloroplast and mitochondrial gene sequences (atpB, psaA, psaB, psbA, psbC,rbcL, andcox1) of taxa covering most of the orders revealed the most related phylogenetic relationship ofZ. leiomorphatoNemoderma tingitanum(Nemodermatales) rather than Ralfsiaceae (Ralfsiales). Morphologically,ZeacarpaandNemodermashare crustose thallus structure and multiple discoidal chloroplasts without pyrenoids in each cell, however, the formation of lateral unilocular zoidangia in tufts in loose upright filaments inZeacarpais distinctive in brown algae. Considering the relatively distant genetic divergence between the two taxa, comparable to that among families or orders in representative brown algae, in addition to the above‐mentioned unique morphological features, we propose the classification ofZeacarpain a new family Zeacarpaceae in the order Nemodermatales.
