Subfamily Plocamioninae Hooper, 2002b Genus Lithoplocamia Dendy, 1922 Type species: Lithoplocamia lithistoides Dendy, 1922 (by monotypy). Diagnosis. Massive or semi-encrusting growth forms. Surface often sculptured by drainage canals. Choanosomal skeleton lacks axial compression, consisting of a dense regular isodictyal (s.s.) or irregular subisodictyal secondary reticulation of acanthostrongyles. Primary skeleton consists of radial or plumose tracts of styles ascending to the surface and protruding slightly through it, only visible near the surface and usually obscured by the dense secondary isodictyal reticulation. Ectosome with specialized skeleton of long, slender oxeas forming sparse bouquets at the ends of primary skeletal tracts. Structural megascleres are smooth styles or subtylo-styles, ectosomal oxeas, diactinal or pseudodiactinal acanthostrongyles, with or without (s.s.) echinating acanthostyles. Microscleres absent (Hooper 2002b).
