Carapace outline subhexagonal/rounded. Frontal margin smooth, either straight or faintly indented in center; front horizontal or only slighlty deflexed; front narrow (fw/cw 0.3); postfrontal crest incomplete, epigastric lobes continuous with postorbital crests, but lateral ends of postorbital crests not meeting anterolateral margins. Exorbital tooth small, pointed; epibranchial tooth large, sharp, directed forward, positioned well behind postfrontal crest. Eyestalks normal length, not tapering distally; cornea not reduced, pigment dorsal and ventral; orbit narrow (1/7 cw), upper orbital margin semi­circular; carapace flat, height less than front width (ch/fw 0.9). Anterolateral margin of carapace between exorbital and epibranchial teeth lacking intermediate tooth; margin granulated, very long, straight, directed outward, then curving sharply backward, forming deep sinus before meeting epibranchial tooth; anterolateral margin of carapace posterior to epibranchial tooth with two small teeth behind epibranchial tooth; margin continuous with posterolateral margin. Carapace sidewall with vertical sulcus, curving upward from longitudinal groove to meet anterolateral margin at exorbital tooth, dividing sidewall into three parts. Second antennal segments broad, filling lateral margins of antennular fossae.
