Diagnosis
Rostrum triangular, narrow base, extending beyond distal apex of compound eyes, carinate along entire length. Subrostral process well developed, occupying proximal third of subrostral margin, anterior and posterior margins forming obtuse angle. Orbital and extra-orbital sinuses deep. Anterolateral spines reaching basal margin of cornea. Epigastric prominences pronounced. Protogastric lobes pronounced. Areola trapezoidal. Cardiac area subrectangular. Epibranchial area slightly elongated. Lobe on proximal dorsal margin of dactylus rudimentary or absent. Carpal ridge high on outer surface of carpus.
