Nyssodrysina haldemani Classification Family Cerambycidae > Subfamily Lamiinae > Tribe Acanthocinini > Genus Nyssodrysina Diagnostic Features of Larvae Larva. Head depressed, widest a little distance behind the epistoma (i.e., slightly tapering both anteriorly and posteriorly); mandible slender, several times the length of the condylar width; labrum twice as wide as long, sparsely haired; antennal ring closed; ocelli not distinct; gula indistinct, very shallow. Posterior area of pronotum velvety, having a border of hairs across anterior area; eusternum and median area of sternellum glabrous, wrinkled; metanotum, mesosternum, and metasternum faintly tuberculate, bordered with velvety pubescence. Ampullae irregularly tuberculate; spiracles orbicular. Ninth tergum bearing a very minute flattened median process on posterior border. Pupa. Resembles Graphisurus except that the pronotum, mesonotum, metanotum, head at base of antennae and the femoral-tibial articulation are beset with a group of long stiff setae; abdominal terga beset with fleshy papillae, each bearing a silky hair. Very similar to Graphisurus except that the caudal spine is extremely minute, scarcely distinguishable with a high-power lens. The ampullae are distinctly tuberculate, consisting of several irregular rows, the dorsal bordered with velvety pubescence. Adapted from Craighead (1923).
