Classification
Diagnostic Features of Larvae
- Mature larva. Head subtrapezoidal, with sides feebly rounded and slightly diverging posteriorly. Gena scarcely shouldered, pale, smooth, bearing several fine, pale setae. Frons smooth, rather narrowly ferruginous anteriorly; sclerotization or mouthframe complete beneath antenna and enclosing ocellus. Hypostoma testaceous, with front margin pale ferruginous. Gula rather broad, distinctly raised. Maxilla with segment 3 of palp longer than segment 2; labial palpi with segment 2 longer than segment 1. Prothorax with pronotum strongly transverse and finely longitudinally striate posteriorly; eusternum faintly and more coarsely longitudinally striate. Abdomen with dorsal and ventral ampullae finely micro-granulate, those on segments 4-6 each with a pair of large rounded, strongly protuberant tubercles placed sublaterally. Anal lobes sparsely setose. Pleural discs indistinct. Legs very small, slender, with unguiculus strongly attenuated. Spiracles with peritreme circular, pale and thin. Length up to 11 mm; maximum breadth (at prothorax) 2.25 mm.
Pupa. Head with vertex visible from above, smooth, glabrous; front smooth and glabrous. Antennae slender, smooth, extending as far as abdominal segment 3, where they are recurved ventrally to terminate near front tibiae; apices gradually thickened, feebly clubbed. Eyes moderately strongly convex, glabrous. Labrum triangular, glabrous. Pronotum very strongly elongate, with sides very strongly constricted sub-basally; disc bearing numerous short setae arranged more or less in three transverse rows, and each arising from a pale basal papilla. Mesonotum with a pair of minute, paramedian setae. Metanotum with one to three pairs of minute, paramedian setae; scutellar groove indiscernible. Elytra and wings extending as far as abdominal segment 3. Abdomen with tergites 1-6 each with a transverse row of short stunted spines (each with a basal seta). Tergite 7 with sides converging posteriorly; median area produced into a pair of oval tuberculate protuberances placed paramedially (each bearing about four stunted spines). Tergite 8 with similar but much smaller protuberances. Segment 9 retracted in segment 8. Sternites glabrous. Pleura moderately protuberant, rugose, glabrous. Legs glabrous, with hind femora extending to between segments 4 and 5, and lying parallel to longitudinal axis of body. Functional spiracles present on abdominal segments 1-6, with peritreme circular, thin and pale. Length up to 12 mm; maximum breadth 3 mm. Adapted from Duffy (1960).
