HOLOTYPE: COLOMBIA: Guainía: Inírida: resguardo indígena La Ceiba , 40 km SO de Inírida, 3.62836°N 67.88268°W, 70 m, 02 Nov 1997 – 09 Nov 1997, C. Rendon, MPUJ_ENT 0046847, 1♀ ( MPUJ). GoogleMaps

DIAGNOSIS BASED ON FEMALE (figs. 1, 3, 5, 6): Recognized by the large body size, slender habitus, and brown coloration with contrasting pale yellow veins.

DESCRIPTION: Female: Total length 8.25 mm, ratio total length to corium width ~3.8, macropterous, hemelytron not reaching apex of abdomen (possibly an artifact, because abdomen somewhat drawn out). COLORATION: Dorsum brown and castaneous, with pale yellow mark at base of membrane and pale yellow lines on membrane tracing corium margin and veins, dorsal laterotergites brown with triangular pale yellow marks; head brown with anteocular area lighter than posterior, labium and antenna light brown, legs light brown, pleura brown to castaneous, abdominal mediosternites brown to castaneous, ventral laterotergites 2–6 with pale yellow patches. SURFACE AND VESTITURE: As in generic description. STRUCTURE: Head ~1.1× as long as wide, eyes in dorsal view fairly large, semiglobular, ratio head width to synthlipsis ~4.1, globular in lateral view, dorsal eye margin surpassing dorsal head surface. Antenna as in generic description, proximal pseudosegment of pedicel ~2.7× as long as scape. Labium as in generic description. Thorax as in generic description, anterior pronotal lobe ~4.6× longer than posterior lobe, posterior lobe moderately wide, finely punctate; scutellum with slender tip. Wings as in generic description with two clearly delimited cells in membrane. Legs as in generic description with ratio forefemur height to length ~0.31. Abdomen and genitalia as in generic description.

Male: Unknown.

ETYMOLOGY: Named for the elongate body shape, after Latin tenuis meaning “thin.”

DISTRIBUTION: Known only from the type locality in lowland Amazonian rainforest in Colombia .

DISCUSSION: We recognize this species based on the slender habitus. The total length may be somewhat misleading, because the abdomen of the holotype is somewhat drawn out. However, the width of the posterior pronotal lobe is distinctly smaller than in other species of similar size (table 1), supporting our decisions to treat this specimen as distinct from other species in the same general geographic area, including C. picturatus or C. globosus .
