Diagnosis

Encrusting sponges generally with hispid surface. Ectosomal skeleton absent. Choanosomal skeleton differentiated into a basal layer of interlacing diactines and, in some cases additional styles; and perpendicular to this layer longer monactines with bases embedded in the basal skeleton. Megascleres in the basal skeleton are diactines of different kinds (strongyles, oxeas, anisoxeas, angulated-centrotylote oxeas, anisoxeas, ceroxas, i.e., m-shape diactines), different shapes (sinuous or vermicular, bent, angulate or centrotylote) and different textures (smooth, evenly or unevenly acanthose, tuberculate or annulate). Rhabdostyles or styles with contorted or reflexed bases are also present. Longer styles (sometimes in two size categories) or tylostyles are located perpendicularly to substrata. Raphides occasionally present.

KEY TO GENERA

(1)Basal skeleton formed only by diactines --------------------------------------------------------------------------------- 2
Basal skeleton includes monactines (rhabdostyles). Diactines bent or angulate oxeas ---------------- Hymerhabdia

(2)Diactines of basal skeleton always smooth, typically vermicular or sinuous. Spicules projecting perpendicular to substrate are long and smooth styles ------------------------------------------------------------------------------- Bubaris
Diactines (including strongyles, toxostrongyles, oxeas and ceroxas) evenly or unevenly acanthose, but smooth ones occasionally present. Spicules projecting perpendicular to substrate are styles and rhabdostyles sometimes in two size categories ----------------------------------------------------------------------------------------------------Cerbaris
Diactines are tuberculate or annulate but smooth ones occasionally present. Spicules projecting perpendicular to substrate are styles and tylostyles ------------------------------------------------------------------------- Monocrepidium
