Classification
Diagnostic Features of Larvae
- Mature larva. Form very elongate, rather slender, subcylindrical. Length up to 47 mm; maxim.um breadth (at prothorax) 9 mm. Head scarcely depressed, widest at middle (maximum head-width 5.2 mm) and distinctly constricted near posterior third. Antennal foramen open behind; inner margin strongly produced beyond basal membrane of antenna. Mouthframe moderately sclerotized. Frons entirely testaceous except extreme anterior margin, with setiferous pores numerous, simple and not longitudinally impressed. Epistoma bearing from twelve to twenty-four long fine setae. One pair of ocelli present; lens large, round, convex; pigmented spot distinct. Hypostoma pale ferruginous, convex; anterior half rather steeply sloping down to front margin, the front margin in a lower plane than hind margin; anterior slope bearing numerous scattered, very long, fine setae; sutures distinct, darkly ferruginous and. slightly incurved. Gula region with a pale median cleavage line. Antenna with segment 2 slightly transverse; segment 3 slender, very elongate, as long as segment 2; supplementary process less than one fourth length of segment 3. Labrum bearing very dense, fine, soft setae. Maxilla with segment 3 of palp conical, shorter than segment 2. Labial palpi with segment 2 cylindrical, elongate, as long as segment I. Mentum not distinct from submentum. Pro thorax with posterior half of pronotum milky white and faintly and coarsely longitudinally striate; a pair of deep sublateral impressions present. Prosternum smooth, with scattered long, fine setae. Abdomen with dorsal ampullae each with two transverse furrows and four (at least medially) rows of glabrous moniliform tubercles which are not interrupted by a median furrow. Ventral ampullae with two rows of tubercles. Segment 9 unarmed. Epipleurum protuberant on all segments. Pleural tubercle without sclerotized pits. Legs vestigial. Spiracles with peritreme broadly oval and with numerous marginal chambers which occupy the entire posterior margin. Adapted from Duffy (1957).
