- Notes: Small tough but crumbly and mucosy cushions with a yellow punctiform surface. Subsuperficial color is dark purple, some specimens thus appearing darker, especially after collecting. Different from Biemna caribea Pulitzer-Finali, 1986 and from B. cribaria (Alcolado & Gotera, 1986). Spicules are styles, 2-3 categories of sigmas, 2 categories of microxea, and raphides. It needs to be compared to Biemna trisigmata Mothes & Campos, 2004, from North Brazil, with which shares many characters.
