Subfamily POLYBIINAE Paul’son, 1875

DISCUSSION

Karasawa et al. (2008) provided diagnoses for the Carcinidae and Polybiinae . Th e new species described below is well accommodated within the Polybiinae based upon its length to width ratio of about 80%; front occupying about 30% maximum carapace width; fronto-orbital width of about 75% maximum carapace width; well-developed posterolateral reentrants; five anterolateral spines including the outer-orbital spine; and hexagonal shape. No other portunoid family accommodates this combination of features.
