The new taxon is distinguished by the labrum with multiple, unorganized setae dorsally; hypopharynx with three-lobed lingua; cleft mandibular incisors; labium with internally curved paraglossae; labial palps with second segment with strong, apically rounded distomedial process and third segment with truncate medial and apical margins; elongate tarsal claws with minute denticles; and absence of scales and scale bases.
