Carapace length 70% width; frontal region about 36% carapace width. Antero-lateral margins curving inward; anterolateral angle blunt. Postero-lateral margins strongly inward. Large cheliped appears elongated in comparison to width (Fig. 25B). Dactyl and pollex longer than manus, blade-like. Gap large, terminus of dactyl overhangs pollex. Tubercles on dactyl gap mostly small; a single large tubercle on proximal third. Pollex with two tubercles located distally (Fig. 25B,C). Tip of pollex trifurcated.
