GENUS PLAKORTIS SCHULZE, 1880

Type species

Plakortis simplex Schulze, 1880

Diagnosis

Thinly to massively encrusting plakinids with a skeleton mostly formed by small (50–200 μm) diods with triods in varying abundance. Deformed calthrops can be found in some specimens. Some species have microrhabds (5–20 μm) distributed regularly in the sponge body. Aquiferous system intermediate between sylleibid-like and leuconoid, with eurypylous choanocyte chambers regularly distributed around exhalant canals. Both ectosomal inhalant cavities and basal exhalant cavities are usually present. Skeleton confuse, dense, without ectosomal specialization or differential location of spicules ( Muricy & Díaz, 2002).
