Description. Male ( Figs 15–18 ). Integument black except yellowish-brown anteclypeus.

Head. Frons densely micropunctate; with yellowish-brown pubescence obscuring integument; with a few long, erect dark setae laterally. Vertex densely micropunctate from area between antennal tubercles, slightly, gradually sparser toward prothoracic margin; area between antennal tubercles and just after posterior margin of upper eye lobes with dense yellowish-brown pubescence obscuring integument, except one nearly glabrous reentrance on each side near upper eye lobes (not present in the holotype); remaining surface nearly glabrous. Area behind upper eye lobes finely, densely punctate close to eyes, finer, somewhat sparser toward prothorax; with dense yellowish-brown pubescence close to eye, glabrous on remaining surface. Area behind connection of eye lobes densely micropunctate toward connection, finely, abundantly punctate toward prothorax (punctures coarser than on area behind upper eye lobes); with narrow yellowish-brown pubescent band close to connection, nearly glabrous on remaining surface. Area behind lower eye lobes tumid, nearly smooth on large area close to eye, finely punctate close to prothorax; with yellowish-brown pubescence partially obscuring integument on tumid area, glabrous on remaining surface. Genae densely micropunctate except smooth narrow distal area; with yellowish-brown pubescence obscuring integument close to eyes, gradually sparser toward glabrous apex. Antennal tubercles with slight longitudinal sulcus near base, densely micropunctate basally, gradually smooth toward apex; with yellowishbrown pubescence nearly obscuring integument on basal area, distinctly sparer toward apex. Median groove distinct from clypeus to near anterior prothoracic margin. Postclypeus widely concave centrally; with somewhat bristly yellowish-brown pubescence on wide central area, but glabrous on center of this area, glabrous laterally; with a few long, erect dark setae on wide central area. Labrum coplanar with anteclypeus at posterior 2/3, inclined at anterior third; with yellowish brown pubescence on posterior 2/3 and row of dark erect setae close to inclined area; inclined area nearly glabrous, with fringe of golden setae at anterior margin. Gulamentum with yellowish- brown pubescence on anterior area, not obscuring integument. Lower eye lobes 0.6 times genal length; connection between eye lobes formed by narrow carina, without ommatidia; distance between upper eye lobes 0.56 times length of scape; in frontal view, distance between lower eye lobes equal to length of scape. Apex of antennomere VI reaching almost reaching posterior third of elytra (antennomeres V–XI missing on the left antenna, and VII–XI missing on the right antenna in the single specimen examined). Scape distinctly widened from apex of anterior quarter to middle, then narrowed toward apex; with yellowish-brown pubescence partially obscuring integument, especially dorsally on basal half. Pedicel with grayish-white pubescence on anterior area, gradually yellowishbrown toward posterior area. Antennomere III with grayish-white pubescence on anterior third, gradually yellowish-brown toward middle, then brownish, less conspicuous toward apex; antennomere IV with grayish-white pubescence until after middle, then brownish, slightly conspicuous toward apex; antennomeres V–VI with grayishwhite pubescence on anterior third, brownish, slightly conspicuous on remaining surface; posterior ventral third of antennomere III irregularly dentate; antennomeres IV–VI irregularly dentate ventrally from near base (gradually larger toward apex). Antennal formula based on antennomere III: scape = 0.65; pedicel = 0.17; IV = 0.78; V = 0.43; VI = 0.36.

Thorax. Prothorax 1.75 times wider than long (including lateral tubercles); lateral tubercles placed at middle, conical, large, with blunt apex. Pronotum with large conical tubercle with blunt apex on each side, from about anterior fifth to after middle (apex directed outward); with wide longitudinal gibbosity centrally, from near anterior area to near posterior area, narrowed and more elevated along middle length; with row of coarse punctures near posterior margin, with finer, sparser punctures on remaining surface, except on tubercles and central gibbosity; with yellowish-white pubescence obscuring integument, except glabrous apex of dorsal and lateral tubercles and central gibbosity, and two circular spots on each side with dark-brown pubescence (one on anterior surface of tubercle, another between posterior margin and tubercle). Sides of prothorax moderately finely, sparsely punctate; with yellowish-white pubescence partially obscuring integument. Prosternum with yellowish-brown pubescence not obscuring integument, denser laterally toward posterior area. Prosternal process about 0.75 times as wide as procoxal cavity, longitudinally, widely carinate centrally, with lateral margins elevated. Ventral side of meso- and metathorax with yellowish-brown pubescence, sparser centrally on mesoventrite, longer, darker centrally on metaventrite. Mesoventral process about as wide as mesocoxal cavity; with distinct tubercle on each side of anterior area. Scutellum with wide, longitudinal dark-brown pubescent band centrally, with grayish-yellow pubescence laterally. Elytra. With distinct carina from anterior area between humerus and scutellum to outer apex, more elevated, somewhat granulated at anterior fifth (anterior area projected forward); with moderately fine, very sparse punctures; humerus projected; with small granules laterally on anterior quarter, starting at apex of humerus; minutely granulated on anterior quarter near suture; apex truncate, with outer angle projected; with grayish-yellow pubescence obscuring integument, interspersed with irregular, small areas with white pubescence, except: nearly glabrous along carina; two elliptical, oblique dark-brown pubescent spots on anterior third (one on each side of carina); two elliptical, fused dark-brown pubescent spots dorsally just after middle; irregular macula with darkbrown pubescence near apex, nearly reaching lateral margin; two subcircular large dark-brown pubescent spots on inclined area, one before middle, another after middle; small dark-brown pubescent spots near suture from apex of anterior third to almost apex; with moderately short, erect, sparse brownish setae on anterior 2/3. Legs. Femora pedunculate-clavate, with peduncle of profemora shorter than in meso- and metafemora; with grayish-yellow pubescence partially obscuring integument on some areas. Protibiae distinctly widened toward apex, with a tooth ventrally at about middle; with grayish-yellow pubescence partially obscuring integument on anterior 2/3 (dorsally interspersed with yellowish-brown pubescence at about middle), brownish, less conspicuous on posterior third. Meso- and metatibiae with narrow anterior ring with brownish, slightly conspicuous pubescence, followed by narrow ring with grayish pubescence, yellowish-brown ring until apex of anterior third (grayish ventrally on this area), wide grayish ring until just after middle, wide ring with dark-brown, bristly, thick (thicker dorsally on mesofemora) setae toward apex (partially interspersed with grayish pubescence near apex). Protarsomeres entirely dark, with very long, dense dark setae laterally on tarsomeres I–III, brown mixed with dark yellowish-brown, long, dense setae ventrally on tarsomeres I–II, short, dense, yellow ventrally on tarsomere III; tarsomere V with sparse grayish pubescence dorsally, gradually brownish toward apex, with moderately long and dense dark setae at posterior half of lateral and ventral sides. Meso- and metatarsomere I with grayish pubescence dorsally, black ventrally; meso- and metatarsomere II with black pubescence dorsally, black basally and laterally and yellowish on remaining surface of ventral side; meso- and metatarsomere III with black setae dorsally, yellow and dense ventrally; meso- and metatarsomere V with moderately sparse grayish pubescence, interspersed with long, erect, dark setae toward apex.

Abdomen. Sides of ventrites with dense yellowish-brown pubescence, gradually sparser, grayish-yellow toward center; posterior area of ventrite V distinctly depressed; posterior margin of ventrite V concave.

Dimensions (mm), 1 male. Total length, 23.40; prothoracic length, 5.20; posterior prothoracic width, 6.35; anterior prothoracic width, 6.35; widest prothoracic width, 9.35; humeral width, 10.50; elytral length, 15.30.

Material examined. COLOMBIA: without detailed location, date and collector indicated, 1 male col. ( MZSP) .

Remarks. Acanthoderes (Scythropopsis) abstersa differs from A. (S.) pupillata as follows: general dorsal pubescence mostly yellowish-white and grayish-yellow; tarsomeres V dark in color; lateral setae of protarsomeres distinctly longer; dark-brown pubescent spots on elytra larger ( Fig. 15 ). In A. (S.) pupillata , the general dorsal pubescence is mostly light greenish-brown interspersed with white pubescence, tarsomeres V are yellowish-brown, lateral setae of protarsomeres are distinctly shorter, and the dark-brown pubescent spots on elytra are smaller ( Fig. 20 ).
