Classification
Diagnostic Features of Larvae
- Mature larva. Length up to 36 mm; maximum breadth (at prothorax) 7.5 mm. Head moderately depressed, slightly elongate, widest at middle and abruptly and strongly constricted near posterior third behind which it is appreciably narrower; frontal sutures distinct for entire length; antennal foramen open behind; mouthframe broadly and strongly sclerotized. Frons entirely ferruginous with eight setiferous pores which are longitudinally impressed; six epistomal setae present. One pair of ocelli present; lens round, feebly convex; pigmented spot rather indistinct. Hypostoma ferruginous, with an abrupt, widely curved ridge across middle; anterior half steeply sloping down to front margin; one pair of distinct setiferous pores present; sutures distinct, pitchy and slightly incurved. Gular region with a pale median ventral cleavage line. Antenna with segment 2 slightly transverse, segment 3 cylindrical, three times as long as broad and as long as segment 2; supplementary process shorter than segment 3. Maxilla with segment 3 of palp acutely conical, as long as segment 2. Labial palpi with segment 2 acutely conical, as long as segment 1. Mentum not distinct from submentum. Prothorax with pronotum very faintly striate and glabrous. Abdomen with each dorsal ampulla with a single transverse, curved furrow and two transverse rows of glabrous tubercles, anterior to which are a few irregularly arranged ones; the two rows are interrupted by a median longitudinal furrow. Ventral ampullae with two rows of tubercles. Segment 9 with a small erect spine (which is simple basally) on middle of posterior margin. Epipleurum protuberant on all segments. Pleural tubercle rather small, with ventral sclerotized pit rather large and very distinct. Legs absent. Spiracles with peritreme broadly oval and with about twenty-four marginal chambers.
Pupa. Length up to 18 mm; maximum breadth 6.75 mm. Head with vertex entirely visible from above, rather deeply excavated between bases of antennae and bearing a few minute scattered setae; front with setae. Clypeus with a transverse impression and two pairs of short setae near basal margin. Antennae extending as far as abdominal segment 3, where they are strongly recurved to terminate near hind coxae. Eyes scarcely convex, each with single seta. Mandibles long, slender, each with a pair of setae near middle of outer face. Labrum thick, fleshy, strongly protuberant and densely setose along front margin and base. Pronotum rugose; front margin bearing numerous short spines (each with a basal seta); disc with a longitudinal median impression across the middle of which is a row of similar spines. Mesonotum rugose, with a few short setae on each side of scutellum which is slightly protuberant and spinose laterally. Metanotum smooth, with a small group of spines on each side of scutellar groove which is distinct. Elytra and wings extending as far as abdominal segment 4. Abdomen with tergites 1-4 each with two more or less complete transverse rows of short, curved, ferruginous spines (each with a basal seta) which are all inclined posteriorly; tergites 5~ with similar spines but with those of posterior row inclined anteriorly. Tergite 7 slightly elongate, with sides converging posteriorly and bearing numerous slightly stouter spines which are inclined posteriorly. Tergite 8 short, transverse, with a row of similar spines. Tergite 9 very short, with hind margin bearing a transverse group of distinctly stouter spines. Sternites glabrous. Pleura moderately protuberant, each with five or more spines. Legs with femora each with a transverse row of four to six stout setae near apex and three to four similar setae along apical half of outer margin; hind femora extending to abdominal segment 5; all tibiae more or less at right angles to longitudinal axis of body. Functional spiracles present on abdominal segments 1-6; peritreme narrowly oval, reniform and slightly raised above general level of cuticle. Adapted from Duffy (1957).
