Loricate choanoflagellates (Acanthoecida) from warm water seas. VIII. Crinolina Thomsen and Diaphanoeca Ellis

The loricate choanoflagellate genera Diaphanoeca Ellis and Crinolina Thomsen encompass a total of ten species. majority these are recorded from the warm water regions reported on here. A distinct morphological dichotomy characterizes genus as currently circumscribed. species distribute themselves within ‘D. grandis subgroup’ pedicellata distinguished e.g., position protoplast inside lorica chamber elaboration anterior projections. We are, while awaiting in particular further molecular evidence, taking conservative approach abstain dealing with subgroup issue at generic level. examination material world’s oceans has resulted description D. sargassoensis sp.n., pseudoundulata throndsenii thorough re-examination undulata. Species share multiple features subgroup. It is yet relevant, both perspective, to retain which remains unambiguously defined based posteriorly open lorica. high level agreement found when contrasting phylogenetic schemes.
