Cordylomera spinicornis
Classification
Diagnostic Features of Larvae
- Mature larva. Closely resembling that of Phoracantha semipunctata, from which it may be distinguished as follows. Length up to 32 mm; maximum breadth (at prothorax) 7.75 mm. Head with genae narrowly ferruginous; area behind ocellus entirely testaceous and with a transverse row of three small oval tubercles, each about the size of ocellus and which in some specimens are contiguous, forming a single large tubercle. Prothorax with lateral regions micro-reticulate and bearing numerous short, reddish setae and with rather inconspicuous lenticulate, glabrous spots; posterior part of pronotum longitudinally rugose.
Pupa. Rather similar to that of Phoracantha semipunctata, from which it differs as follows. Length up to 23 mm; maximum breadth 5 mm. Pronotum with lateral tubercles obtuse, blunt and feebly defined. Scutellum acutely and strongly produced posteriorly. Abdomen with tergites 1-6 each bearing numerous spines which ace closely set and arranged in a single, almost straight, row. Tergite 7 with a row of spines arranged to form a semicircle. Legs with all femora strongly petiolate; hind femora simple at base. Functional spiracles present on segments 1-6; peritreme rather narrowly oval and very strongly raised above general level of cuticle. Adapted from Duffy (1957).
Biology and Economic Importance
- Members of this tribe are native to Australasian region. Several species have been introduced worldwide, for example Phoracantha recurva (eucalyptus longhorned beetle). More information on this genus is available at: cabi.org.
