Oeme rigida Classification Family Cerambycidae > Subfamily Cerambycinae > Tribe Oemini > Genus Oeme Diagnostic Features of Larvae Larva. Form elongate, slender, cylindrical; integument thin, shining, sparsely covered with long, light, castaneous hairs. Head subtriangular, depressed, strongly tapering anteriorly; mouth-frame slightly corneous; clypeus and labrum thin, latter orbicular; mandibles black, shining, slightly constricted near apex, basal piece indistinct; antennae short, retractile, conical, last joint slender, much longer than third, supplementary distinct; one black ocellus, not contiguous with antennae. Ventral mouth-parts in distinguishably fused by submentum with gula; process of palpifer distinct, as also process on first maxillary joint; maxillary palpi short, conical, ultimate joint slightly shorter than penultimate, shorter than last labial; gula soft, deeply sunken below anterior curved edge of hypostomal plates; gena not shouldered, bristles dense, long and slender. Prothorax transversely depressed, short, pronotum rectangular, of essentially same texture throughout, or slightly reticulated behind, no median suture; sternum shining, reticulated, ventro-lateral sutures widely diverging anteriorly; sternellar fold broadly fused at extremities into epipleurum. Mesonotum and metanotum with straight transverse impression. Legs short, conical, four-jointed, joints globular, femur and tibia shorter than maxillary palpi. Abdominal segments elongate; dorsal ampullae alutaceous, shining, marked by two lateral impressions, a shallow median longitudinal furrow, and two transverse impressions forming a fusiform diamond-shaped area. Pleural disc faint on first segment, distinct on second and third, faint on fifth. Abdominal spiracles minute, oval, peritreme thin. Adapted from Craighead (1923).
