Philematium virens Classification Family Cerambycidae > Subfamily Cerambycinae > Tribe Callichromatini > Genus Philematium Diagnostic Features of Larvae Mature larva. Length up to 25 mm; maximum breadth (at prothorax) 7 mm. Head pale testaceous, strongly rugose, with rounded divergent sides; frontal sutures indistinct; front margin of frons very strongly sinuate medially, swollen and pale testaceous; genae pale, testaceous and bearing numerous short, ferruginous, bristly setae. Labrum quadrate, with front margin strongly rounded and densely fringed with reddish setae. Mandible with basal part testaceous, separated from apical, pitchy part by a transverse impression. Antenna small, salient; segment 3 cylindrical, about four times as long as basal width; supplementary process very short. One pair of ocelli present just behind and ventrad of antenna; lens convex, narrowly oval; pigmented spot indiscernible. Maxilla with segment 3 of palp shorter than segment 2; dorso-external process of palpifer extremely small. Labial palpi with segment 2 cylindrical, much shorter than segment l. Hypostoma entirely testaceous, transversely strigose and sparsely setose; sutures strongly curved. Gula broad, strongly raised. Prothorax with anterior part of pronotum strongly rugose and bearing scattered reddish setae; posterior part coarsely and longitudinally strigose. Abdomen with each dorsal ampulla bearing two deep, transverse furrows; shining, coarsely vermiculately rugose. Anal lobes sparsely setose. Pleural discs indistinct. Legs 4-segmented, longer than maxillary palp. Spiracles with peritreme testaceous, very thin, broadly oval and without marginal chambers. Adapted from Duffy (1957).
