Asemum striatum Classification Family Cerambycidae > Subfamily Spondylidinae > Tribe Asemini > Genus Asemum Diagnostic Features of Larvae Mature larva. Similar to those of Arhopalus species, from which it differs as follows. Length up to 20 mm; breadth (at prothorax) 5.8 mm. Head less depressed (maximum head-width 4.9 mm), with sides more strongly diverging behind middle; genal setae shorter, finer, testaceous. Labrum slightly wider than long. Gular sutures slightly raised and almost as darkly pigmented as hypostomal sutures. Maxillary palpi with apical segment almost as long as second segment. Prothorax with lateral setae only moderately dense; pronotum with posterior part pale testaceous and much more finely asperate. Abdomen with urogomphi longer and stouter, subcontiguous at base and with apical third (at most) strongly sclerotized. First-instar larva. Length up to 1.5 mm; breadth 0-45 mm. Abdomen with urogomphi indiscernible. Egg-bursting spines present on meso- and metathorax, and on abdominal segments one to eight; form rather as in Rhagium bifasciatum. Legs with unguiculus extremely attenuated. Spiracles biforous Pupa. The pupa of this species is rather similar to those of Arhopalus species, from which it differs as follows. Length 10-18 mm; maximum breadth 7 mm. Head with vertex with two groups of short spines intermingled with numerous short pale setae; front with a transverse row of short spines above base of clypeus. Antennae transversely rugose, densely spiculate and with at least three short spines on each segment; extending to just beyond middle of metathorax, where they are strongly curved downward to terminate near bases of elytra. Maxillary palpi spiculate and with a few short pale setae. Pronotum strongly transverse, with sides strongly rounded, and with scattered stout, ferruginous spines and long fine setae, especially along front margin. Mesonotum with a few fine setae; scutellum broad, rather depressed and glabrous or almost so. Metanotum with a few scattered minute spines on each side of scutellar groove. Abdomen with tergites one to six each bearing four transverse groups of numerous thorn-like, ferruginous spines. Seventh and eighth tergites with scattered stout spines. Sternites with lateral groups of spines, except the ninth, which bears only two stout spines, and the tenth, which is glabrous. Functional spiracles with peritreme rather thick and raised above general level of cuticle. Adapted from Duffy (1953).
