Remark Chondropsidae
Definition: Myxillina with only thin smooth strongyles or occasionally thin smooth styles as megascleres, in an irregular plumose arrangement; no acanthostyles; microscleres arcuate or unguiferate chelae and/or sigmas.
Diagnosis: Encrusting, massive, flabellate or digitate growth forms. Ectosomal skeleton frequently absent, replaced by arenaceous or spicular detritus, but often with areolate porefields on surface. Ectosomal smooth strongyles or occasionally styles, often rare or secondarily lost. Choanosomal spicules, if present, are auxiliary megascleres of ectosomal origin, strongyles or occasionally styles, whereas principal spicules appear to be absent. Microscleres are arcuate isochelae and sigmas, but these may be often absent.
Remarks:
Tornotes: The strongyles are presumably of tornote derivation; many are thin and have often slightly asymmetrical ends and may occasionally be stylote. The styles of one genus (Phoriospongia) show slightly swollen tyles, indicating possible homology with choanosomal principal megascleres.
Sand: Many members of this family have their skeleton partly or wholly replaced by sand grains.
Microscleres: Based on the presence or absence of microscleres, there is a series of intergrading ‘genera’: Batzella (no microscleres), Phoriospongia (sigmas), Strongylacidon (unguiferate chelae sigmas), Burtonispongia (arcuate chelae sigmas). It is here proposed to ignore the presence or absence of sigmas and/or chelae at the genus level. The entire absence of microscleres (Psammoclema, Batzella) makes allocation to family arguable, and consequently these genera are retained for possible allocation to other groups, even though the distinction among them is probably artificial. Batzella and Chondropsis differ in the presence or absence of a sand reticulation, which may also be an artificial distinction.
Affiliations: This is a small somewhat suspect, dustbin-type group. Possibly various genera could be reduced members of Hymedesmiidae.
Scope: Sixteen genera are assigned to the family, of which five are considered valid: Batzella, Chondropsis, Phoriospongia, Psammoclema, Strongylacidon.
