Subgenus
Latrunculia
du
Bocage, 1869
Diagnosis.
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
).
