Corimbion kuckartzi Santos-Silva, Galileo and Wappes View in CoL , new species

( Fig. 1–7 View Figures 1–7 )

Diagnosis. Corimbion kuckartzi is similar to C. vulgare Martins, 1970 , but differs as follows: typically, each elytron with a clearly evident heavy single brown fascia on basal half, less commonly the fascia is reduced to a thin line or small dark spots, and outer angle of each elytron acute but not spined. In C. vulgare the elytral color pattern is also variable, but at least has a wide, dark band on distal half, and the outer angle of each elytron distinctly spined. From C. supremum Martins, 1970 it also differs by the outer angle of each elytron lacking a spine (spined in C. supremum ), and by the brown fascia on elytra not extending along suture to base or prolonged along suture to apex (in C. supremum the fascia extends to the base and is prolonged to apex (see photographs of paratypes at Bezark 2015).

Description. Holotype male ( Fig. 1-4 View Figures 1–7 ). The following brown (with some areas more reddish or darker): head; scape; prothorax (except base of prosternum centrally); mesosternum (except for central region close to mesosternal process); metasternum (except for central area close to metacoxae); inverted V- shaped fascia (includes both elytrons) on basal 1/2 of elytra, includes suture but not lateral margins; distal 1/3 of mesofemoral club; metafemoral club and abdominal ventrites. The following reddish brown: base of prosternum centrally; area of mesosternum close to mesosternal process; mesosternal process. The following yellowish to reddish brown: pedicel; antennomeres III–XI (distinctly yellowish toward distal segments); profemora; most of mesofemora; peduncle of metafemora; tibiae; tarsi; central area of metasternum close to metacoxae. Remaining surface area of elytra yellowish brown.

Head. Frons densely, confluently, finely punctate; with sparse, very short, yellowish setae centrally, distinctly denser close to base of antennal tubercles and eyes. Area between antennal tubercles with sculpture and setae as on central area of frons. Area between apex of antennal tubercles and prothorax smooth centrally, abundantly finely punctate laterally; with sparse short yellowish setae interspersed by scattered long setae on punctate area. Area behind upper eye lobes abundantly finely punctate on wide, oblique band from apex of lobe to margin of prothorax; remaining surface smooth; with moderately abundant short yellowish setae on punctate area, remaining region glabrous. Area behind lower eye lobes tumid, smooth close to eye, sparsely finely punctate on remaining surface; with very sparse short yellowish setae. Genae abundantly finely punctate close to eye, smooth close to apex; with sparse short setae on punctate region. Submentum abundantly transversely striate, with fine punctures interspersed; with sparse short yellowish setae interspersed by longer setae. Antennal tubercles toward apex acute, in frontal view horn-shaped; abundantly finely punctate at base, gradually sparser toward apex; with sparse short yellowish setae. Longitudinal sulcus distinct from clypeus to posterior level of antennal tubercles. Distance between upper eye lobes 0.55 times length of scape; in frontal view, distance between lower eye lobes 0.85 times length of scape. Antennae 2.9 times elytral length; reaching elytral apex at basal 1/4 of antennomere VII. Scape abundantly finely punctate on basal 1/2, gradually sparser toward apex; with narrow but distinct longitudinal sulcus on basal 1/3 of dorsal surface; with sparse short yellowish setae interspersed with long setae. Antennomere III–IV wide; remaining antennomeres gradually narrower distally; antennomeres III–IV with sparse long yellowish setae on inner side ventrally; antennal formula based on antennomere III: scape = 0.52; pedicel = 0.18; IV = 0.77; V = 0.96; VI = 1.02; VII = 1.12; VIII = 0.91; IX = 0.83; X = 0.67; XI = 0.94.

Thorax. Prothorax 1.65 times longer than wide; with distinct constrictions after basal 1/6 and before anterior 1/5. Pronotum with moderately distinct longitudinal gibbosity on each side of anterior 1/ 2, and distinct, carina-shaped tubercle centrally; with white pubescence not obscuring surface, more distinct (depending on angle of light source) on some areas, distinctly sparse on three longitudinal regions: one centrally and one on each side; with sparse, very coarse shallow punctures, each puncture bearing a long seta. Sides of prothorax with white pubescence. Prosternum with wide band of white pubescence on each side of basal 1/2; anterior 1/2 transversely striate laterally in basal region, remaining surface nearly smooth; areas outside of pubescent bands with very sparse short white setae. Prosternal process with horizontal surface distinctly narrowed toward apex; narrowest area about 1/4 as wide as basal width of profemoral peduncle. Mesosternum finely pubescent. Metepisterna with moderately dense white pubescence. Sides of metasternum with moderately dense white pubescence gradually becoming sparser toward center. Scutellum with dense white pubescence. Elytra abundantly coarsely, very shallowly punctate throughout, sparsely interspersed with moderately fine punctures, each puncture bearing a long seta; apex shallowly emarginate.

Abdomen. Ventrites I–IV with whitish pubescence, slightly denser laterally, sparsely interspersed with long setae. Ventrite V with whitish pubescence throughout; apex slightly rounded and broadly truncate.

Legs. Femora with whitish pubescence dorsally and laterally, sparsely interspersed with long setae, glabrous ventrally.

Female ( Fig. 5-7 View Figures 1–7 ). Primarily differs from male by shorter antennae: 2.1 times elytral length, reaching apex at distal third of antennomere VIII.

Variation. Primarily in integument color or reduced elytral pattern with inverted V-shaped fascia on elytra absent or greatly reduced (sometimes only a small oblique macula or spots remain); scape from yellowish brown to brown; antennomeres entirely yellowish; frons distinctly reddish brown; metasternum mostly yellowish brown; mesofemoral club mostly brown, almost entirely yellowish brown, or entirely yellowish; part of metafemoral peduncle and entire club brown; head and prothorax almost entirely reddish brown; abdominal ventrites reddish brown (sometimes with base of ventrite I yellowish brown).

Dimensions (mm). Holotype male/ paratype males (2) / paratype females (4). Total length (including mandibles) 10.20/7.60–11.30/9.53–13.50; prothoracic length 2.30/1.65–2.45/1.95–2.55; anterior prothoracic width 1.30/0.90–1.35/1.20–1.58; basal prothoracic width 1.35/0.95–1.40/1.13–1.58; humeral width 2.00/1.45–2.20/1.73–2.32; elytral length 6.10/5.00–7.10/6.30–9.00.

Etymology. We are pleased to name this new species for Kenneth Paul Kuckartz, one of the collectors of specimens in the type series as well as a long-time friend and collecting partner of the third author.
