Description.
Body (Fig. 7 A – C). Larvae length 19.2–20.0 mm, width 2.3–2.5 mm, moderately thickened. Body yellowish brown, shiny, body wall ossified; median line obvious on pronotum and mesonotum.
Head (Fig. 7 B, D – G). Labrum transverse; apical part with six setae; anterior margin with two discal and six slender lateral marginal setae; epipharynx with sparse setae on lateral margin, with two basal spines on central area, between the basal spines with four mastoids, with six mastoids above the basal spines; mandible left-right unsymmetrical, membranous elevation with two setae (Fig. 7 D, E, G). Epicranial stem Y-shaped; frons convex, with sparse setae on lateral margins, with four pairs of setae at apex (a pair on anterior margin, a pair on middle margin, two pairs on mid-posterior margin) (Fig. 7 D, F). Ocelli evident, two parallel rows arranged transversely (Fig. 7 B). Maxillary palpi (Fig. 7 E) three-segmented, cylindrical, and conical at apex; I widest, II longest. Labial palps two-segmented, short; II conical; prementum short, with two setae on anterior margin, apex with two long setae; mentum convex, trapezoidal, base of mentum straight; mentum wide and short, lateral margin with five or six long setae, mid-posterior margin with two long setae; submentum with nine setae on middle margin. Antennae three-segmented, cylindrical at apex; I longest; III shortest and narrowest (Fig. 7 B, D – G).
Thorax (Fig. 7 A). Pronotum and mesonotum with four pairs of setae (two pairs of setae on anterior margin, two pairs of setae on posterior margin); metanotum with three pairs of long setae, a pair on mid-anterior margin, two pairs on middle. Anterior and posterior borders of pronotum with brown longitudinal stripes; posterior border of mesonotum and metanotum with a brown longitudinal stripe. Pronotum longest, 2.03 × as long as mesonotum, 1.89 × as long as metanotum, mesonotum shortest.
Legs (Fig. 7 H, I). Protarsungulus with a strong, long seta on inner side and a strong, short spine on outer side at base. Profemora and protibiae gradually narrowing towards apex; inner margin setal formula of prothoracic leg 5 (1): 7 (5–6): 2 (2); outer margin of tibiae with two strong and short spines; outer margin of femora with two setae; trochanter with three setae. Mesotarsus with a strong, long seta on inner side and a strong, short spine on outer side at base; inner margin setal formula of mesothoracic leg 4 (2): 4 (2): 2 (2); outer margin of tibiae with two spines; outer margin of femora with two spines; outer margin of trochanters with two spines and one seta (Fig. 7 H). Metatarsus with a strong, long seta on inner side and a strong, short spine on outer side at base; inner margin setal formula of metathoracic leg 4 (3): 5 (2): 2 (2), outer margin of tibiae with two spines, outer margin of femora with two spines, outer margin of trochanters with two spines and one seta.
Abdomen (Fig. 7 A, C). Not constricted between VIII and IX segments Approximately 2.68 × as long as thorax; abdominal segments I – VIII subcylindrical, with transverses plicae; ventral side of abdominal segment I with 12 setae on anterior margin and six setae on each side, with two pairs of setae on posterior margin; ventral side of abdominal segment II with seven pairs of setae (five pairs of setae on lateral margin, two pairs of setae on posterior margin); ventral side of abdominal segments III – VIII with three pairs of setae (two pairs of setae on mid-lateral margin, a pairs of setae on posterior margin); ventral side of abdominal segment VIII with four pairs of setae on lateral margin and two pairs of setae on posterior margin. Last segment conical, 0.91 × as long as VIII, distinctly narrower than VIII; last segment surface of convex disc with sparse long setae in ventral view, with a row of short spines on each side (five spines on left, five spines on right); last segment dorsally flattened, urogomphi inconspicuous, with two short spines (Fig. 7 J – L).
Spiracles (Fig. 7 C). Lateral margins of abdominal segments I – VIII and mesothorax each with a pair of oval spiracles, mesothorax spiracles much larger than abdominal spiracles, abdominal segments I – VIII spiracles gradually shrinking.
