Genus Strongylodesma Lévi, 1969

Type species. S. areolata Lévi, 1969: 959, pl. 2, fig. 4c.

Diagnosis. Latrunculiidae with a packed ectosome of paratangential strongyles and, in most species, a clear subectosomal band of collagenous mesohyl. Choanosomal architecture consists of megascleres arranged in an irregular, large-meshed reticulation formed by insubstantial or heavy tracts of megascleres, which are smooth or terminally spined strongyles, in a single, broad, size category, many of which have characteristic ‘shepherd’s crook’ modifications. Species contain pyrroloquinoline alkaloids such as batzellins, isobatzellins, discorhabdins and their derivatives (abbreviated and modified from Samaai et al. 2009).
