(Figs. 1–4)
Description. Female. Integument black, dark brown on some areas; gula yellowish brown; labial palpomeres I–II and maxillary palpomeres I–III reddish brown, narrowly pale yellow at apex; last labial and maxillary palpomere dark brown on basal 2/3, gradually reddish brown on distal third.
Head. Frons finely, sparsely punctate; with yellowish white pubescence almost obscuring integument, more yellowish, slightly longer laterally, glabrous on narrow band along median longitudinal groove; with long, erect, sparse, dark setae (longer laterally). Area between antennal tubercles with sculpture, pubescence and dark setae as on frons. Area between upper eye lobes and remaining surface of vertex with dense, yellow pubescence, obscuring integument, except on glabrous narrow band along median longitudinal groove; area between posterior margin of upper eye lobes and prothoracic margin finely, sparsely punctate (punctures coarser than on frons). Antennal tubercles finely, sparsely punctate on basal area, sub-smooth on distal area; pubescence yellowish, slightly less dense than on frons, interspersed with long, erect, sparse, dark setae. Tempora tumid close to lower eye lobes; subsmooth behind upper eye lobes, coarsely, sparsely punctate close to lower eye lobes, minutely, abundantly punctate on glabrous area behind lower eye lobes; with yellow pubescence, obscuring integument, except glabrous close to prothoracic margin, behind lower eye lobes; with long, erect, sparse, dark setae on tumid area. Submentum with sparse, whitish pubescence interspersed with long, erect, dark setae. Postclypeus with yellowish white pubescence, interspersed with long, erect, dark setae, except sub-glabrous lateral area. Labrum convex; with sparse, brownish pubescence basally, gradually, longer, more abundant, yellow toward apex. Distance between upper eye lobes 0.05 times length of scape; in frontal view, distance between lower eye lobes 0.55 times length of scape. Antennae 1.9 times elytral length, reaching elytral apex at middle of antennomere VIII; ventral side of scape, pedicel and antennomeres III–X with long, erect, dark setae, gradually sparser toward antennomere X; antennal formula (ratio) based on antennomere III: scape = 0.91; pedicel = 0.18; IV = 1.27; V = 1.06; VI = 0.97; VII = 0.88; VIII = 0.82; IX = 0.79; X = 0.69; XI = 0.79.
Thorax. Prothorax 1.1 times wider than long; sides with blunt protuberance at middle. Pronotum coarsely, abundantly punctate except on narrow, smooth, transverse band close to basal and distal margin; with grayish-white pubescence, partially obscuring integument, except three wide, longitudinal band with dense yellow pubescence between smooth bands (central band reaching basal margin); with some long, erect, dark setae. Sides of prothorax with grayish-white pubescence close to pronotum, grayish-white interspersed with yellow setae close to ventral side, with wide, longitudinal band with yellow pubescence centrally; coarsely, abundantly punctate. Prosternum smooth; with grayish-white pubescence (not obscuring integument), more conspicuous laterally. Prosternal process coarsely, sparsely punctate except near apex where punctures are more abundant and confluent; with grayish-white pubescence interspersed with long, erect, yellowish and dark brown setae, distinctly longer, more abundant on distal third. Mesoventrite sub-smooth, notably transversely depressed close to apex of prosternal process; laterally with conspicuous grayish-white pubescence, more yellowish close to mesanepisternum. Mesanepisternum and mesepimeron with dense, yellow pubescence, more grayish-white near margins. Metanepisternum with yellow pubescence obscuring integument. Sides of metaventrite with dense, yellow pubescence obscuring integument (wider centrally); remaining surface with grayish-white pubescence interspersed with long, erect, sparse, yellowish setae, except sub-glabrous, narrow central band. Scutellum with dense, yellow pubescence obscuring integument. Elytra. Coarsely, abundantly punctate on basal half, distinctly finer, sparser on distal half. Each elytron with four, longitudinal band with dense, yellow pubescence; three outermost yellow bands interrupted near middle by transverse, dense band with white pubescence; innermost and third band fused near apex; second band reaching base of distal sixth; outermost reaching apex; remaining surface with grayish-white pubescence before white band, with yellowish brown pubescence after white band; with thick, dark, erect, sparse setae throughout; apex obliquely truncate, with outer angle slightly projected and sutural angle rounded. Legs. Femora with yellow pubescence, more grayish laterally and ventrally.Tibiae with yellowish pubescence on basal third, gradually, distinctly darker toward apex; distal half with long, erect, thick, dark setae, denser toward apex. Metatarsomere I as long as 0.85 times II–III together; metatarsomere V (without claws) as long as 0.75 times I–III together.
Abdomen. Ventrites with wide lateral band with yellow pubescence, grayish-white on remaining surface; interspersed with long, erect, sparse, yellowish setae, denser, darker on distal half of ventrite V; apex of ventrite V truncate.
Male. Differs from female mainly by the antennae longer (2.15 times elytral length, reaching elytral apex at distal third of antennomere VII), and by the apex of ventrite V narrow, centrally emarginate.
Variation. Transverse white band of pubescence on elytra more yellowish; elytra apex distinctly projected at outer angle.

Etymology. This species is named for James E. Wappes, collector of the holotype and other specimens in the type series.
Remarks. RΟsalba wappesi sp. nov. is similar to R. arawakiana Villiers, 1980, but differs as follows: the longitudinal bands of yellow pubescence on sides of pronotum are narrower, about as wide as central one; longitudinal bands of yellow pubescence on basal half of elytra narrower, not convergent toward middle, more distinctly separated between then; second innermost longitudinal bands of yellow pubescence of elytra not fused to the first and third at distal area of elytra. In R. arawakiana the longitudinal bands of yellow pubescence on sides of pronotum are distinctly wider than the central band, the longitudinal bands of yellow pubescence on basal half of elytra are wider, convergent toward middle and slightly separated between then, the three innermost longitudinal bands of yellow pubescence of elytra are fused at distal area of elytra.
