Description

Body. Small to medium-sized; body length 6.8-10 mm; elongate-cylindrical. Integument unsclerotized, entirely whitish to yellowish. Caudal ridge absent. Mature larvae unable to jump.

Head. Head of normal shape; cephalic lobes slightly developed. Antenna 2-segmented.

Stomal organ: primary lobe rounded, protuberant; with 1 unbranched peg sensillum.

Stomal region: secondary lobes absent; sclerotized stomal guards present. Oral ridges present; number of oral ridges 3-7, margins dentate (sharply pointed teeth). Accessory plates usually absent, sometimes one accessory plate present. Elongate, finger-like lobes arising above mandibles absent. Median oral lobe absent or not protruding. Labium broad.

Cephalopharyngeal skeleton. Mandibles: subapical teeth absent. Parastomal bars elongate, free from hypopharyngeal sclerite. Dental sclerites apparently absent, not visible in lateral view..

Anterior spiracles. Anterior spiracles convex to flat. Variable amount of anterior spiracular tubules, ranging 13-20; either in a single uniform row or a single irregular row.

Spinules and creeping welts. Dorsal spinules on T1-A6, sometimes with unusual distribution.

Caudal segment (A8) and anal lobes. Sensilla on caudal segment 10 pair, with at least 7 pair visible under dissecting microscope. Usually with intermediate caudal sensilla I1a&b and I2 on a single tubercle.

Posterior spiracles. Posterior spiracular area not distinctly set off from caudal segment. Posterior spiracles: slits 3-5x longer than wide. Dorsal spiracular processes with relatively few trunks. Number of spiracular processes variable. Area between posterior spiracles with cellular or rugose appearance.
