Diagnosis.
Pale yellow with extensive dark areas (Fig. 1A View Figure 1 ); clypeus longer than half of head height; vertex more than two and a half times as wide as eye width; antenna shorter than length from apex of clypeus to apex of abdomen; scutellum with basal depression extended longitudinally; embolium bent upwards from its anterior end to more than half its length; cuneal fracture long; and cell in membrane with the interior margin anteriorly concave.
Description.
Macropterous female. Coloration. Head pale yellow (Fig. 1A View Figure 1 ). Clypeus apex black (Figs 2A View Figure 2 , 3A View Figure 3 ). Labium pale yellow, segments III-IV darker. Eyes black. Antennal segment I dark brown, base pale yellow; segment II dark brown, with faint basal ring yellow; segments III-IV brown. Thorax: collar and calli pale yellow. Posterior pronotal lobe dark brown, lateral margins pale yellow. Scutellum pale yellow, apex dark brown. Pleural area pale yellow, excepting metaepisternum dark brown dorsally. Hemelytron: embolium pale yellow; clavus basal half pale yellow and posterior half dark brown; corium anterior and posterior areas pale yellow, and medially dark brown; external apex of corium and cuneus orange, cuneus apex dark brown; membrane dark brown with dark brown veins. Legs: coxae, trochanters, femora except apex and basal three quarters of inner face of protibiae pale yellow; apex of femora, rest of protibiae, meso- and metatibiae dark brown; tarsi dark brown with segments I-II paler. Abdomen dark brown.
Surface. Head with short, erect setae, more abundant on posterior margin and area adjacent to eyes in dorsal view (Fig. 1A View Figure 1 ). Labium with semierect setae. Antennal segments II-IV with abundant recumbent setae and some longer semierect setae. Collar, posterior pronotal lobe, scutellum, and hemelytra with abundant, short, erect, yellowish setae, except those on dark brown areas of hemelytra darker. Calli glabrous (Fig. 3A View Figure 3 ). Veins with very short erect setae. Pleura and abdomen with longer and more dispersed erect setae than dorsum. Coxae, trochanters, femora and tarsi with semierect setae. Tibiae with abundant dark recumbent and semierect setae, thicker than the ones in the femora.
Structure. Head: vertex almost twice length of antennal segment I; upper margin at eye level (Fig. 2A View Figure 2 ), with median longitudinal depression. Labrum not extending half way on labial segment I (Fig. 3A View Figure 3 ). Gular area not visible. Antennal segment II thinner and between 3-4 times as long as antennal segment I. Antennal segment III almost twice the length of antennal segment I. Thorax: anterior collar margin concave and posterior margin convex, posterior sulcus shallow medially (Fig. 1A View Figure 1 ). Posterior pronotal margin width more than twice its length; anterior pronotal width less than half posterior pronotal margin width. Calli not attaining lateral pronotal margins. Scutellum with triangular basal depression extended longitudinally. Hemelytron: embolium bent upwards from its anterior end to more than a half its length. Medial fracture shorter than one quarter of corium length. Claval commissure longer than scutellum and half of pronotum length together. Cuneal fracture evident, straight, attaining half of corium width. Interior margin of cuneus concave. Membrane with interior margin concave anteriorly, and posterior margin straight with middle weakly concave (Fig. 1A View Figure 1 ).
Measurements (n: 2): Body length to apex of membrane (5.60), 5.70; body length to apex of cuneus 4.60, (4.70). Head: width 1.28; interocular distance 0.73, (0.74), and (1.38), 1.42 times head height. Labium: segment I length 0.80, (0.86); II, 0.91, (0.96); III, (0.32), 0.34; IV, 0.27, (0.29). Antenna: segment I length (0.40), 0.41; II, 1.55; III, (0.75), 0.80; IV, (0.62), 0.66. Pronotum: length (0.92), 0.95; anterior width 0.95; posterior width 1.92, (1.97). Scutellum: length 0.72, (0.74); width 0.85. Cuneus: length 1.00; anterior width 1.04. Membrane cell (2.06), 2.16 times longer than wide.

Type material.
Holotype ♀: Panama: Barro / Col[orado] Isl., 17 Mar. / 1985, J. E. Loye coll. [9°9'N, 79°51'W] (USNM). Paratype ♀: Panama: Barro / Col[orado] Isl., 17 Mar. / 1985, J. E. Loye coll. // Neoneella / sp. / det. T. J. Henry 1987 (MLP).
Etymology.
The specific epithet is the Latin adjective setosus, - a, - um, meaning ‘bristly’, in allusion to the abundant short, erect setae of the dorsal surface.
