Scientific Details

Rostrum well developed and continued posteriorly as carina. Rostrum 1-2 times as long as wide at base, bearing stiff setae laterally, free section shorter than orbitorostral grooves which are overhung by base of rostrum and sharply delimited from orbital hoods; orbital hoods without teeth; rostrum-hood margins transverse. Orbitorostral process usually present. Pterygostomial angle not produced. Chelipeds markedly asymmetrical, larger one swollen, carried extended, dactylus with plunger fitting into socket at base of fixed finger. Large chela laterally compressed; lower margin slightly concave, irregular proximally; upper margin with longitudinal ridge and tubercles; without lateral and mesial teeth near dactylar articulation; with numerous scattered setae. Small chela not of balaeniceps form. Pereopod 2 with first carpal segment slightly longer than second. Smaller cheliped with fingers simple. Pereopods 1-4 with epipods. Pleuron of abdominal somite 6 without an articulating posterior triangular plate.
