Front with 4 distinct obtuse triangular teeth; median pair distinctly smaller than lateral, with short, broadly V-shaped median notch; lateral frontal teeth separated from median ones, with asymmetric U-shaped notch approximately twice depth of median notch, outer margins slightly sinuate. Inner orbital tooth reduced but forming distinct obtuse angle extending anteriorly beyond first anterolateral tooth; notch undeveloped, indicated as short suture. Supraorbital margin with well-developed medial notch and one indistinct lateral notch. Infraorbital margin granular with a distinct V-shaped lateral notch and a prominent obtuse medial tooth approximately level with the frontal teeth in dorsal view. Anterolateral margin slightly convex, with 6 teeth; anterior 5 teeth projecting forward, first tooth bluntly rounded and smaller; second to fifth teeth subequal in size and gradually sharper posteriorly; sixth tooth (epibranchial) projecting laterally, spiniform, strong, about three times longer than preceding one, posterior margin straight, 2.5 times longer than anterior margin. Posterior part of carapace distinctly narrower than anterior one, posterolateral margin of carapace oblique, short, about half length of anterolateral margin; posterolateral angle forming laterally and upward-directed subacute tooth-like process; posterior margin slightly convex.

Upper surface of palm with 2 longitudinal crests, inner one distinct, ending distally into strong, compressed, obliquely anteriad erected spine reaching distal dorsal end of palm, outer crest defined only by row of granules and ending with small distal spine and distinct spiniform proximal tooth proximally over articulation with carpus. Outer surface with 2 granular crests ending on level of finger joint; inner surface of palm flattened, with 1 indistinct longitudinal keel. Fingers straight, tapering, 0.5 of maximum chela length, distinctly carinate; movable finger with distinct bilobed molariform tooth proximally on cutting edge; fingers otherwise with some bi- or trilobed serial conical teeth separated by series of small simple teeth.
