Smodicum cucujiforme Classification Family Cerambycidae > Subfamily Cerambycinae > Tribe Smodicini > Genus Smodicum Diagnostic Features of Larvae Mature larva. Length up to 13 mm; maximum breadth (at prothorax) 2.2 mm. Form cylindrical, very slender, scarcely tapering. Head salient, quadrate, broadest before middle, very pale testaceous, and very feebly sclerotized. Genae smooth, pale, sparsely setose. Mouthframe pale testaceous, feebly sclerotized. Antenna pale, fleshy: second segment slightly elongate; third segment stout, slightly tapering; supplementary process as long as third segment and strongly attenuated. Mandible short, basal third yellowish, apical two-thirds pitchy, with a longitudinal groove on outer face. Labrum strongly transversely oval, fleshy, and sparsely setose. One pair of ocelli present; lens convex, protuberant; pigmented spot distinct. Hypostoma smooth, pale; sutures pale, indistinct. Gula narrow, raised; sutures concave, pale. Maxilla white, fleshy; third segment of maxillary palpi one and one-half times length of second; process of palpifer minute. Labial palpi with third segment elongate, one and one-half times length of second. Prothorax quadrate, dull, testaceous; pronotum with posterior half shining and finely longitudinally striate; median cleavage line indistinct. Eusternum distinct, triangular, without spines or setae but with several distinct striae. Abdomen with ampullae prominent, small, shining, alutaceous; pleural discs on segments one to three slightly granulate. Tenth segment barrel-shaped, strongly protuberant. Legs distinctly three-segmented but shorter than maxillary palpi. Spiracles minute, peritreme broadly oval, thin and pale. Pupa. Length up to 11 mm; maximum breadth 2.5 mm. Head with vertex visible from above; round , glabrous. Antennae extending as far as second abdominal segment, where they are recurved to terminate near apical third of elytra. Eyes strongly convex, glabrous. Pronotum elongate, depressed, and with at most a few scattered pale papillae. Mesonotum and metanotum bearing a few fine short setae. Elytra and wings extending as far as fourth abdominal segment. Abdomen with tergites one to seven micro-pubescent and bearing scattered pale spines arising from small tuberc1es. Sternites without spines or setae. Legs with hind femora extending as far as fourth abdominal segment. Functional spiracles present on first seven abdominal segments; peritreme thin and pale.
