Body. Body length 7–11mm.

Head. Cephalic lobes moderately developed. Stomal organ: Number of peg sensilla two, or three, or four or more; peg sensilla unbranched; other peg-sensilla-like structures present (with small, sharply pointed spinules scattered over surface of stomal sensory organ and adjacent preoral lobe). Stomal region: Number of oral ridges 6–10; margins entire, or serrate . Accessory plates present (well defined); number of accessory plates 8–9 (~~); margins unserrated.

Spinules and creeping welts. Dorsal spinules on segments T1-T3, or T1-A1, or T1-A2, or T1-A3, or T1-A4, or T1-A5, or T1-A6.

Anterior spiracles. Anterior spiracle convex to flat, or concave medially, appearing bilobed. Anterior spiracular tubules 11–18.

Caudal segment (a8) and anal lobes. Anal lobes plainly visible, but not protuberant; simple, or grooved, or bifid.
