Abstract

The reddish dye of the genera Miniacina GALLOWAY, 1933, Homotrema HICKSON, 1911 and Sporadotrema HICKSON, 1911 seems to be a single organiccompound identical in all three genera. With their tests looking similar in colouration and arborescent habit, the genera are difficult to distinguish. Yet their megalospheric embryos are structurally different and therefore allow a reliable distinction of the abundant megalospheric tests of each genus. Concerning the adult chamber morphology, thetest of Homotrema and Miniacina is built by expanse chambers, the oneof Sporadotrema by chamberlet cycles. Only in Sporadotrema merging pores can be found, and only in Homotrema there are stylae left standingby intensive resorption of the inner test. Thus, the red-coloured, lamellar-perforate arborescent foraminifera belong to three different taxonomic groups with Miniacina and Homotrema being related closer to each other than to Sporadotrema.
