Leptura quadrifasciata Classification Family Cerambycidae > Subfamily Lepturinae > Tribe Lepturini > Genus Leptura Diagnostic Features of Larvae Mature larva. Length up to 24 mm; breadth (at prothorax) 5.5 mm. Form subcylindrical, moderately robust and very slightly tapering. Head appreciably narrower than prothorax; rather thick, robust, moderately transverse (maximum bead-width 4.25 mm); temples rugose and ferruginous behind ocellus and genae with a deep, transverse furrow immediately in front of ocellus. Six epistomal setae present. Antenna with third segment subquadrate, moderately sclerotized and bearing a few stout setae; second segment with supplementary process short, stoutly conical, and as long as third. Mandible with cutting edge without an oblique, striated plate but with at least four setae on outer face near base. Labrum with numerous setae along front margin and a row of longer setae across middle. One pair of ocelli present; lens large and rather protuberant towards sides; pigmented spot indistinct. Hypostoma about four times as wide as median length; bearing numerous fine setae; sutures slightly curved; anterior margin ferruginous. Gula narrow; sutures slightly raised. Maxilla with sides of palpal segments not strongly rounded or constricted basally; third segment shorter than second, quadrate; lobe with numerous long setae. Labial palpi separated by slightly more than their own width. Prothorax scarce depressed, about twice as wide as long; dorsally sclerotized, testaceous and with a very pale, ferruginous band across front margin; lateral grooves distinct only for basal third; anterior part of pronotum transversely rugose, posterior part vermiculate-rugose. Proeusternum, mesonotum, metanotum and sterna dull, velvety spiculate. Abdomen with ampullae present on tergites one to six and sternites one to seven (the seventh being very much smaller); each dorsal ampulla with two deep, transverse furrows, and four transverse rows of bead-like tubercles. Pupa. Length 13-35 mm; maximum breadth 6.5 mm. Head elongate, triangular, very faintly rugose; vertex visible from above, with a group of at least six short stout setae on a protuberance above base of each antenna; front with numerous similar setae opposite base of each antenna and with a deep transverse impression above; clypeus with a transverse row of four to six setae. Antennae extending as far as second abdominal segment where they are strongly curved downward to terminate near apex of mid tibiae. Eyes large, convex and bearing a few small setae. Mandible with two small setae near middle of outer face. Labrum strongly transverse, more or less rectangular, usually glabrous, but occasionally with a few minute setae. Pronotum quadrate, broadest at base and with hind angles acute and slightly produced; front margin with a raised, tubercular protuberance bearing small scattered setae; basal half with two oblique, elongate, tuberculate areas, each bearing a row of long stout setae; disc with several much smaller setae. Mesonotum with two groups of short stout setae. Metanotum with two oval tuberculate areas, each bearing numerous short stoat setae. Elytra and wings extending to fourth abdominal segment. Abdomen with tergites one to six each equipped with paired transverse, oval protuberances (each bearing a row of closely set papillae which bear stout apical setae); seventh and eighth tergites elongate, with scattered stout setae on posterior half. Ninth tergite short, with sides converging posteriorly; bearing a few scattered short setae, and terminating in a pair of horizontal, excurved urogomphi, which are strongly sclerotized in their apical third. Sternites three to seven each with a transverse group (interrupted medially) of minute setae. Eighth sternite with two to four setae. Ninth sternite with about six stout setae on each lateral margin. Tenth sternite glabrous (the paired tubercles, present only in the female, are each produced into an acute, conical process). Pleura strongly protuberant, each with a pair of short stout setae. Legs with a row of minute setae at apex of outer face of each femur; hind tibiae each with large paired apical spurs; tarsi longer than tibiae, each with a single seta near apex; hind femora extending to fourth abdominal segment. Functional spiracles present on first five abdominal segments; peritreme broadly oval, very thick, but scarcely raised above general level of cuticle. Adapted from Duffy (1953).
