A). Attached via sclerite. Basis with large, rounded posterior margin. Merus sub-triangular, with ventral seta. Carpus twice as long as broad, with small proximal seta, one ventral seta, shield very shallow, without crenulation. Propodus and spine as long as carpus, twice as long as deep, dorsal crest with about five nodules or crenulations and outer ventral margin with short crenulate ridge, with two setae, small outer seta near dactylus. Fixed finger with four relatively delicate teeth on incisive margin, three outer setae and short, blunt terminal spine. Dactylus with dorsal margin crenulate (about ten–12 nodules), more finely so for distal half, with spine on incisive margin.
