Callipogon barbatum
Classification
Diagnostic Features of Larvae
- Mature larva. Head scarcely depressed; front margin of frons pitchy, with upper boundary only carinate sublaterally; lower boundary broadly produced over clypeus (even for median third) and produced more strongly laterally into an acute angle. Postcondylar carina shallow, pitchy, ferruginous. Subfossal process rather thick and blunt. Antenna 2-segmented; segments l and 2 extremely elongate, both at least three or four times as long as basal width; the latter obliquely truncate and bearing sensory pores and setae. Three pairs of ocelli present; lens round, convex; pigmented spot indiscernible. Mandible moderately robust, pitchy, basal half strongly rugose; apical half smooth and with a strongly raised transverse carina on apical third. Clypeus glabrous. Labrum ferruginous posteriorly and rather densely fringed anteriorly with stiff reddish setae. Maxillary palp 3-segmented, segment 3 shorter than segment 2. Labial palpi 2-segmented, segment 2 shorter than segment 1. Prothorax with pronotum and prosternum rugose, sparsely setose, shining. Abdomen with ampullae each with a pair of transverse furrows, glabrous, nontuberculate. Spiracles with peritreme broadly oval. Length up to 85 mm., maximum breadth (at prothorax) 21 mm.
Pupa. Head salient, not concealed from above by prothorax, glabrous. Mandibles extending anteriorly, moderately to strongly robust, glabrous. Antennae thick, filiform, extending posteriorly as far as abdominal segment 3, where they are slightly curved inwards. Pronotum transversely rectangular with basal angles dentate; dis transversely striate, glabrous, distinctly and completely margined posteriorly. Mesonotum and metanotum transversely striate, glabrous; scutellum rather thick and protuberant; scutellar groove with a pair of parallel longitudinal ridges. Elytra and wings extending as far as abdominal segment 4. Abdomen with tergites rugose and bearing numerous scattered ferruginous spinules; gin-traps present on segments 2-3, 3-4, 4-5 and 5-6; each consisting of two transverse protuberances, the anterior one thick and labiate, the posterior one thin and carinate. Sternites glabrous or almost so. Legs with hind femora extending as far as abdominal segment 4. Functional spiracles present on abdominal segments 1-6, the seventh and eighth pairs being closed and probably non-functional; peritreme rather broadly oval, moderately thick and slightly raised above general level of cuticle. Length up to 60 mm; maximum breadth 16 mm. Adapted from Duffy (1960).
