Latrunculia species in which the anisodiscorhabd microscleres have six visibly distinct substructures: the manubrium, basal whorl, median whorl, subsidiary whorl, apical whorl, and apex (modified from Samaai et al. 2006 ). Remarks. Species in this subgenus are easily recognisable by examination of the number of whorls and the degree of fusion between the various substructures in the anisodiscorhabds. Figure 1 A illustrates the diagnostic microscleres that define subgenus Latrunculia . In subgenus Latrunculia , there are three distinct whorls of projections around the shaft, between the manubrium and the apex. In the majority of species, the basal whorl is clearly separated from the manubrium, however, in some of the spicules of a few species, these structures are less well separated from each other (see Hajdu et al. 2013 ). Figure 16 A–P illustrate the diagnostic anisodiscorhabds for living species of the subgenus Latrunculia ( Latrunculia ) .
