Body. Length 8.7–11.4 mm.

Head. Stomal organ peg sensilla unbranched; other peg-sensilla-like structures present.

Cephalopharyngeal skeleton.

Spinules and creeping welts. Dorsal spinules on segments T1-T2 or T1-T3 or with an unusual distribution.

Anterior spiracles. Anterior spiracular tubules 15–21; in a single uniform row.
