Carapace broadly oval, moderately convex; surface medially punctate; gastro-cardiac (H-shaped) grooves present but not strongly marked; epigastric regions separated by median groove; epigastric crests absent or poorly developed; postorbital crests low or absent; branchial regions not markedly swollen, lacking anterolateral striations, punctate; cervical grooves shallow, poorly marked; anterolateral margins smoothly cristate, evenly convex, with one, more or less distinct, but always small epibranchial tooth. Frontal and orbital margins with raised rim. Exorbital angle spine moderately blunt. Posterolateral borders straight, convergent posteriorly, bearing oblique striations. Front more or less bilobed. Male pleon broadly triangular; somites 4 and 5 strongly tapering; somite 6 slightly tapering; telson length subequal to breadth at base, tongue-shaped. Small species, typically less than
