Mandible tapering from broad base to long slender apex (fig. 39B); apex pigmented; mandible of cleared specimen seen in dorsal, inner, or ventral views (fig. 3A, B) slender, tapering evenly from base to pointed apex; apical concavity narrow, about as long as distance from mandibular base at base of cusp; dorsal edge of apical concavity with numerous long, slender, sharp spines; ventral edge smooth or nearly so; dorsal mandibular surface (fig. 3A) strongly spiculate particularly near basal edge of apical concavity; some spicules also on basal inner surface of concavity. Body: Anterior body segments with distinct but small, projecting, paired dorsolateral tubercles (fig. 39A), thoracic ones of which tending to be darkly pigmented.
