Diagnosis Test large, up to 8 mm in diameter, attached, variable in form, globose, hemispherical, or encrusting with conical projections or erect branches, _early chambers in spiral or clustered arrangement, later in numerous layers, walls may be partially resorbed as layers are added, producing large and irregular passages; wall calcareous, hyaline, optically radial, early chambers with organic wall, later wholly calcareous, intercameral walls imperforate, septa elevated at the surface, upper chamber wall coarsely perforate, commonly red in color, probably as a result of partial decomposition of chlorophyll pigments of endosymbionts; aperture consisting of the large perforations. Miocene to Holocene; cosmopolitan in warm waters. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
Grammatical gender ICZN 30.1.2. a genus-group name that is or ends in a Greek word transliterated into Latin without other changes takes the gender given for that word in standard Greek dictionaries;
The suffix -trema comes from the Greek τρῆμᾰ (neuter): hole, aperture, perforation.
Hickson (1911, p. 451) stipulates: "The specific name of the only species of the genus Homotrema should be “rubrum” (Lamarck)." clearly indicating that the genus is neuter. [details]
