Diagnosis. Dorynota wappesi belongs to a group of species characterized by impunctate elytral intervals, a pronotum which is at most finely punctate, a long postscutellar elytral spine, humeral angles with a costa and moderately expanded laterally, and a rather narrow explanate elytral margin. The group is comprised of D. aurita and D. rileyi . Dorynota aurita differs in that it has a U-shaped body and a strongly elevated humeral carina, while D. wappesi has an elongate-triangular body and a low humeral carina. Dorynota rileyi has a similar body shape and form of the humeri, but differs in that the explanate elytral margin is maculate, the antennae are uniformly yellow with only the terminal antennomeres slightly infuscate, the prosternal process is much more widened apically, and the scutellum is regularly rhomboidal, while D. wappesi has an immaculate explanate elytral margin, seven distal antennomeres infuscated, the prosternal process weakly widened apically, and the scutellum subrhomboidal with a convex anterior margin. For the main diagnostic characters to distinguish D. wappesi from other related species, see Table 1.

Description. Measurements (n = 1): Body length 11.5 mm, body width 7.5 mm, body length/width ratio 1.5, pronotal length 2.5 mm, pronotal width 5.3 mm, pronotal width/length ratio: 2.2. Body elongate-triangular, regularly converging from base to apex. Integument shiny, disc of elytra and pronotum opaque with transparent explanate margins; pronotum and elytral disc with short, sparse, yellow setae, denser ventrally. Ground color of dorsum yellow; pronotum with M-shaped spot on disc ( Fig. 37 ) and basal margin black; elytral punctures with black fovea, suture and humeral calli black, explanate margin uniformly yellow, only apex somewhat darkened ventrally ( Fig. 38 ); 3 basal antennomeres yellow, remainder infuscate brownish black; ventral side yellow with basal margin of abdomen, posterior half of metathorax, and areas around coxae black. Antennae with 5 basal antennomeres glabrous, 6 distal antennomeres densely setose; scape ca. 3X longer than pedicel, tapered towards apex. Length ratio of antennomeres: 100:33:27:47: 60:67:67:53:67:63:100. Pronotum semicircular, with maximum width approximately in the middle, disc finely and sparsely punctate, except anterior half with coarse punctures; anterior margin strongly emarginate but this could be an artifact due to inadequate emergence from the pupa as seen in other Dorynota species ; lat- eral margins rounded and convex; posterior angles truncate. Explanate pronotal margin moderately broad, smooth, shiny, sparsely punctate, transparent and with honey-comb structure. Prosternum with prosternal collar projecting anteriorly, not covering mouthparts; process flat, weakly constricted and with short, rhomboidal apex, surface smooth, shiny, and sparsely pubescent with long setae. Scutellum subrhomboidal, impunctate, smooth and shiny, with convex anterior margin. Elytra strongly convex and projecting in sharp postscutellar spine. Dorsal spine 3.5 mm long, 2X longer than its base and 1.4X longer than height of elytra. Base of elytra much wider than base of pronotum, strongly emarginated due to projecting humeral angles; basal margin serrate in emargination, denticles obtuse and swollen. Humeral angles strongly projecting anterad and reaching midlength of pronotum, with oblique carina extending from humeral callus to outer corner, truncate anterior margin, obtuse corners, outer corners slightly expanded laterally and situated slightly posteriorly to inner ones. Disc coarsely and partly irregularly punctate, sutural and 5 lateral intervals regular; intervals distinct, mostly narrower than puncture diameter, only 2 nd interval slightly wider than puncture diameter, smooth, shiny, impunctate, and sparsely pubesent with extremely short and barely visible adherent setae. Punctures deeply impressed, foveolate, fovea micro-reticulate thus semiopaque. Due to strongly impressed punctures, intervals appear to form low ribs, particularly 1 st behind dorsal spine and 4 th and 6 th nearly their entire length. Marginal row of punctures distinct in entire length, interrupted twice around midlength, its punctures with smaller diameter than those on disc but more deeply impressed. Ultimate interval slightly wider than remaining lateral ones. Explanate elytral margin converging posterad, smooth, finely and sparsely punctate, micro-reticulate but shiny, its outer margin swollen thus appearing slightly canaliculate.

Distribution. Bolivia (Santa Cruz) ( Fig. 46 ).

Etymology. The species is named in honor of the collector of the holotype, Jim Wappes (San Antonio, Texas), friend and a specialist in Bolivian Cerambycidae .
