Micas afecundus .— Ng & Richer de Forges 1996: 265. Distribution . Central Queensland, Australia . Remarks . Halicarcinus afecundus , from Lindeman I., Queensland, Australia , was assigned to Micas by Ng & Richer de Forges (1996) on account of the short ‘trilobed’ rostrum, longitudinal groove on the cardiac region, elongate ambulatory dactyli and pleomeres 2–5 fused. They did not remark on the two subterminal dactylar teeth on pereopods 2–5 which also uniquely characterise this genus. Ng et al . (2008) catalogued it as a species of Halicarcinus without explanation.
