Latrunculia (Latrunculia) tetraverticillata sp. nov. (Porifera, Poecilosclerida, Latrunculiidae) from the bathyal region off the coast of Santa Catarina State, Brazil, Southwestern Atlantic Author Mothes, Beatriz Author Campos, Maurício Author Eckert, Rafael Author Lerner, Cléa text Zootaxa 2008 1744 59 65 journal article 10.5281/zenodo.181621 ac4be4df-efb4-47be-872d-239e8b6b73d5 1175-5326 181621 Subgenus Latrunculia Du Bocage, 1869 Definition. Latrunculia species in which the anisodiscorhabd microscleres have three whorls of spines around the shaft, a basal whorl above the manubrium, and two whorls of projections, the median and subsidiary whorls, located closer to the apical whorl than to the manubrium (hence the use of the prefix aniso- in anisodiscorhabd). The basal whorl is clearly separated from the manubrium in most species but armours the manubrium in others, making the distinction from the manubrium more difficult ( Samaai et al ., 2006 ).
