Xystrocera globosa
Classification
Diagnostic Features of Larvae
- Mature larva. Length up to 44 mm; maximum breadth (at prothorax) 7.1 mm. Head trapezoidal, with maximum bead-width 4.9 mm. Genae strongly shouldered. Temples narrowly ferruginous ventrad of antennae and bearing numerous short, bristly setae. Sclerotization of mouthframe ferruginous and narrowly interrupted beneath antennae. Antenna with segment 2 about one and one-half times as long as basal width; supplementary process conical, about one-fourth length of segment 3. Mandibles short, broad, entirely pitchy. Labrum transversely oval, with anterior margin very densely fringed with short, pale setae. Ocelli indiscernible, probably absent. Hypostoma with front margin broadly and very strongly sclerotized and very faintly transversely striate; sutures distinct, slightly incurved. Gula slightly raised; sutures concave, distinct. Maxillary palpi with segment 3 not longer than segment 2; dorso-external process of palpifer distinctly attenuated. Labial palpi with segment 2 shorter than segment l. Prothorax transverse, slightly wider posteriorly, with numerous very short, pale setae and interspersed glabrous spots on lateral regions; pronotum with median cleavage line distinctly impressed; anteriorly testaceous, shining; median area rather coarsely punctate and bearing short setae; posteriorly finely and closely longitudinally striate. Prosternum with a pair of triangular, shining, slightly rugose areas. Abdomen with ampullae dull, reticulate, rugose and microscopically spiculate; strongly bilobed, especially those on posterior segments. Pleura microscopically pubescent, with a few longer setae. Legs distinctly 4-segmented, pale. Adapted from Duffy (1957).
Biology and Economic Importance
- Members of this tribe are native to the Australasian and Afrotropic regions. One species, Xystrocera globosa, has been introduced to several countries. More information on this genus is available at: cabi.org.
