Dorsal setae enlarged, apically acute or slightly rounded, not capitate; ventral tubular ducts medial between middle legs, with a few near base of hind legs; dorsal submarginal tubular ducts often present around body margin, same size or smaller than ventral ducts; claw with or without small denticle.
