Sylvanelater furtivus

Appearance

Description (of genus). Body elongate, subparallel, convex. Integument piceous with metallic reflections; finely to moderately punctured, punctures umbilicate on lateral portions of head and pronotum; pubescence moderately long, pallid to cinereous. Head with frons flat to slightly convex; supra-antennal ridge directed medially. Antenna moderately serrate; male antenna long, reaching 2–4 segments beyond apex of pronotal hind angle, female antenna reaching half length of pronotum; segment 3 broadened, subserrate. Pronotum with length 1.1–1.2 X width; disc slightly to moderately convex, with shallow median canaliculation posteriorly; hind angle oblique at apex; dorsal carina absent to weakly defined; basal incisures short, indistinct. Prosternum with anterior lobe extended, length 0.11 X width (female) to 0.33 X width (male), moderately deflexed; intercoxal process slightly arcuate. Hypomeron with mesal margin with narrow, flattened, sparsely punctate bead that becomes a slightly elevated carina near anterior angle; posterior margin slightly emarginate near hind angle. Scutellum subpentagonal, flat dorsally. Mesepimeron narrowly adjacent to coxal cavity. Metaventrite with anterior intercoxal process subtriangular. Elytral striae striatopunctate, shallowly sulcate; intervals flat to slightly convex, punctures moderately sparse, shallow; apex rounded. Aedeagus with median lobe slightly deflexed apically; lateral lobe dentate latero-apically, apex membranous, asetose. Gonocoxites lightly sclerotized; ovipositor rods longer than 0.5 X length of ventrites 1–5; bursa copulatrix expanded, with two saccate colleterial glands, with opaque collar at constriction; spermathecal receptacle saccate, arcuate, wall corrugated and lightly sclerotized; spermatheca short, elongate-saccate; spermathecal reservoir long, tubular; accessory gland duct thick basally, gradually narrowing from spermathecal receptacle. Sexes dimorphic, exceptionally so in S. cylindriformis.
