Classification
Diagnostic Features of Larvae
- Mature larva. Length up to 35 mm; maximum breadth (at prothorax) 8.5 mm. Head slightly rugose, with rounded divergent sides; frontal sutures indistinct, median adfrontal suture well defined. Front margin of frons narrowly ferruginous. Labrum semicircular. Mandible short, robust; basal part pale, separated from apical pitchy part by a deep transverse impression. Antenna small, salient; third segment cylindrical, at least twice as long as basal width. One pair of ocelli present just behind and ventrad to antenna; lens small, oblong, convex (often indistinct in mature larvae); pigmented spot grey, rather indistinct. Maxilla with third segment of palp shorter than second; maxillary lobe glabrous on entire inner margin; dorso-external process of palpifer extremely small. Hypostoma with front margin very narrowly ferruginous; sutures broadly curved. Gula very broad; sutures indistinct. Prothorax with lateral regions bearing numerous short, fine setae. Pronotum rectangular, glabrous, milky white and shining; posterior half rather coarsely and longitudinally rugose. Abdomen with dorsal ampullae marked by a shallow median longitudinal furrow, one anterior transverse, straight furrow and a posterior transverse, bilobed furrow; their extremities being connected with a pair of deep, lateral furrows. Anal lobes rugose, with scattered short setae. Pleural discs indistinct. Legs four-segmented, longer than maxillary palp; unguiculus strongly sclerotized, ferruginous and imbricately spinose. Spiracles with peritreme thin, testaceous.
Pupa. Length 20-33 mm; maximum breadth 6 mm. Head totally concealed from above; elongate, triangular; vertex dome-shaped, smooth and usually glabrous; front smooth and glabrous; clypeus with a deep transverse impression at base, glabrous. Antennae extending as far as third or fourth abdominal segment, where they are recurved ventrally. Eyes feebly convex, glabrous. Labrum cordate, glabrous. Pronotum with sides bearing a pair of lateral tubercles; front margin strongly produced medially, V-shaped, and bearing several groups of short fine setae (their distribution varies somewhat intraspecifically). Mesonotum with a few very fine short setae; scutellum pointed, transversely striate, glabrous. Metanotum smooth, bearing a few fine short setae; scutellar groove rather broad and shallow. Elytra and wings extending to fourth abdominal segment. Abdomen with tergites one to six with paired, transversely oval groups of short spines, which are inclined forward (not backward, as in the majority of species). Seventh tergite much less transverse, with hind margin produced and V-shaped; bearing a transverse group of similar spines near hind margin. Eighth tergite with hind margin V-shaped; usually bearing a pair of setae. Ninth segment partly retracted into eighth and very short. Sternites smooth and glabrous. Legs with hind femora extending almost to, or as far as, sixth abdominal segment and lying parallel to longitudinal axis of body. Functional spiracles present on first seven abdominal segments, but a rudimentary pair present on eighth segment; peritreme narrowly oval, thick and slightly raised above general level of cuticle.
