(Figs. 18–22)
Description. Male. Integument orange; head, scape, pedicel, antennomeres III–IV, distal 1/5 of elytra, distal 1/6 of femora, and tibiae black; antennomere V brownish with apex dark-brown; antennomeres VI–X light reddish-brown with apex brown; antennomere XI light reddish-brown; abdominal ventrite IV reddish-brown on base, gradually brown toward apex; abdominal ventrite V dark-brown.
Head. Frons smooth close to clypeus, finely, abundantly punctate laterally toward antennal tubercles; punctate region with short, decumbent, sparse setae. Vertex finely, abundantly punctate throughout, except sparsely punctate part of area between upper eye lobes; with short, sparse, decumbent setae between upper eye lobes, glabrous on remaining surface. Antennal tubercles smooth, except finely, abundantly punctate area close to apex; with short, decumbent, sparse setae. Area behind eyes finely, abundantly punctate, mainly close to upper eye lobe, gradually sparser toward inferior side of lower eye lobe; with short, sparse setae except on narrow area close to distal half of lower eye lobe with abundant setae. Gula transversely striate, mainly toward submentum, glabrous centrally, with short, decumbent, sparse setae laterally and on area close to submentum. Submentum, transversely striate-punctate laterally and on area close to gula, microsculptured, finely, sparsely punctate on remaining surface; with short, erect, sparse setae interspersed with some long, erect setae. Genae minutely punctate; with minute, decumbent, sparse setae. Postclypeus finely, abundantly punctate laterally, finely rugose centrally; laterally with short, sparse, decumbent setae, interspersed with some short, erect setae and one very long, erect seta; glabrous centrally. Distance between upper eye lobes 0.35 times length of scape; distance between lower eye lobes in frontal view 0.50 times length of scape. Antennae 3.1 times elytral length, reaching elytral apex at apex of antennomere VI; scape dorsally rugose-punctate, mainly on basal half; antennomeres III–VI dorsally carinate; antennomeres III–X with long, erect setae on inner side of ventral side, sparser toward X; antennal formula (ratio) based on antennomere III: scape = 0.62; pedicel = 0.14; IV = 1.03; V = 1.18; VI = 1.20; VII = 1.16; VIII = 1.05; IX = 1.05; X = 1.00; XI = 1.33.
Thorax. Prothorax 1.2 times longer than wide; barrel-shaped in dorsal view; sides coarsely, abundantly punctate, except striate anterior region (wider toward ventral side); with some long, erect setae. Pronotum with five, slightly elevated gibbosities: one at each side of basal half, one at each side of distal half, one centrally on basal half; coarsely, abundantly punctate, mainly on distal half and laterally, smooth on gibbosities; with some short, erect setae. Prosternum centrally transversely, finely striate except striate-punctate distal region; coarsely, abundantly punctate laterally on basal half; with longitudinal band with short, sub-erect, moderately abundant setae on each side of basal half; center of basal half with short, sparse setae, sparser toward distal half; distal half with short, sparse setae. Prosternal process narrowed centrally. Ventral side of mesothorax moderately finely, sparsely punctate, except smooth central area of mesosternum closer to prothorax. Apex of mesosternal process deeply emarginate, about as wide as 3/4 of mesocoxal cavities. Metepisternum finely, sparsely punctate; with minute, sparse setae except densely pubescent distal region. Sides of metasternum finely, sparsely punctate, pubescent; remaining surface coarsely, sparsely punctate, with long, erect, sparse setae. Scutellum glabrous on base, finely pubescent on remaining surface. Elytra. Moderately finely, abundantly punctate, sparse on distal quarter; with long, erect, sparse setae; distal margin obliquely concave, with long triangular projection at outer angle and short triangular projection at sutural angle. Legs. Femora with long, erect, sparse setae; profemoral club with triangular projection dorsally; metatarsomere I as long as 1.3 times II–III together.
Abdomen. Ventrites with long, erect, sparse setae, denser on ventrite V; apex of ventrite V truncate.
Dimensions (mm). Holotype male. Total length (including mandibles), 13.60; prothoracic length, 2.80; anterior prothoracic width, 1.85; posterior prothoracic width, 1.85; largest prothoracic width, 2.35; humeral width, 2.85; elytral length, 8.50.
Type material. Holotype male from PANAMA, Panama: Bayano (2.5 km W Ipiti), 11–22.V.1996, Wappes, Huether & Morris col. (FSCA).
Etymology. The new species is named after our friend James E. Wappes.
Remarks. Ectenessa wappesi sp. nov. is similar to E. villardi Belon, 1902, mainly by the general color, but differs by the profemora dorsally without keel and with a distinct triangular projection (Fig. 22). In E. villardi, the dorsal side of profemora has keel without triangular projection (Fig. 23). It shares with E. lurida Martins, 1973 by the shape of profemora, but differs by the elytra black at apex (Fig. 18), and by the head, basal segments of antennae, tibiae and tarsi dark (Fig. 18). In E. lurida, the head, entire antennae, entire elytra, femora, tibiae and tarsi are light (Figs. 24–25).
