Classification
Diagnostic Features of Larvae
- Mature larva. Length up to 90 mm; maximum breadth (at prothorax) 15 mm. Form cylindrical, moderately robust, slightly tapering posteriorly. Head moderately depressed, slightly transverse (maximum head-width 7.3 mm). Gena strongly shouldered, smooth, testaceous to ferruginous, with a distinct vertical carina beneath ocelli. Mouthframe moderately sclerotized, ferruginous; setal punctures shallow. Front margin of frons ferruginous, moderately strongly sclerotized; upper boundary flattened, slightly produced above clypeus, with front margin regular; lower boundary produced over clypeus (more strongly so laterally), with front margin curved but regular. Postcondylar carina shallow. Subfossal process conical. Antennae partly retracted, 2-segmented, segment 2 elongate, gradually narrowed to apex where it is obliquely truncate and bears a few sensory setae. Labrum transversely oval. Three pairs of ocelli present beneath antennal foramen; ocellar lens convex; pigmented spot indiscernible owing to strong sclerotization of lens. Ventral mouthparts moderately strongly sclerotized, testaceous to ferruginous for greater part. Prothorax scarcely sloping anteriorly. Pronotum with a transverse ferruginous band. Prosternum rugose but not tuberculate. Abdomen not sclerotized, milky-white, fleshy; ampullae not callose. Pleural discs not contrasting in color with surrounding cuticle; indiscernible on segments 7 and 8.
Pupa. Length up to 46 mm; maximum breadth 11 mm. Head salient, not concealed from above by prothorax, smooth, glabrous. Mandibles extending anteriorly, very stout and bearing a few very fine, scattered, pale setae on outer face. Antennae robust, segments strongly pectinate apically, slightly curved (but not recurved ventrally) and terminating near abdominal sternite 5. Pronotum strongly transverse, with sides each bearing three large spine-like tubercles, the middle one the longest and curved posteriorly; disc with a median fovea around which it is protuberant, strigose, and bears subconical tubercles which are spinose apically. Mesonotum transversely strigose and with a few spinules on the protuberant scutellum. Metanotum smooth, with numerous scattered spinules. Elytra and wings extending as far as abdominal segment 5. Abdomen with tergites bearing numerous scattered, short spinules, each with a subapical seta; gin-traps absent. Sternites glabrous or almost so. Legs with hind femora extending to abdominal segment 6. Functional spiracles present on abdominal segments 1-6; peritreme narrowly oval, pale, rather thick and raised above general level of cuticle.
