Lepturges (Lepturges) brechlini Santos-Silva, Nascimento & Kozlov , sp. nov.

( Figures 22–25 )

Description. Male. Integument mostly dark brown, almost black on some areas; mouthparts dark reddish brown; anteclypeus and anterior half of labrum reddish brown; antennomeres III–VI dark reddish brown, with distal area blackish; distal area of abdominal ventrites I–IV, and base of V reddish brown. Pale-yellow pubescence more yellowish-white depending on light intensity.

Head. Frons very finely, densely punctate; with pale yellow pubescence not obscuring integument, interspersed with short, sparse, erect yellowish setae. Vertex very finely, moderately sparsely punctate between upper eye lobes, smooth toward prothoracic margin; with yellowish pubescence between antennal tubercles and close to eyes, light yellowish-brown between upper eye lobes, denser between antennal tubercles, becoming absent toward prothoracic margin. Area behind eyes very finely, moderately abundantly punctate close to eyes, smooth toward prothoracic margin; with dense yellowish pubescence close to eye (this area slightly widened toward ventral surface), glabrous on remaining surface. Antennal tubercles basally with sculpturing as on frons, smooth on remaining surface; pubescence as on frons anteriorly, slightly yellower toward eye, not obscuring integument. Median groove distinct from clypeus to prothoracic margin. Genae very finely transversely striate-punctate except smooth distal area; with sparse pale yellow pubescence close to eye, glabrous on remaining surface. Postclypeus with sparse, bristly pale yellow pubescence on wide central area, glabrous laterally. Labrum coplanar with anteclypeus at posterior 2/3, inclined at anterior third; with sparse brownish pubescence, posteriorly interspersed with long, erect, sparse dark setae. Gulamentum glabrous on posterior horizontal area, with sparse yellowish pubescence on anterior vertical area. Distance between upper eye lobes 0.25 times length of scape; in frontal view, distance between lower eye lobes 0.45 times length of scape. Antennae 2.45 times elytral length, reaching elytral apex at middle of antennomere VI; scape with pale yellow pubescence not obscuring integument; pedicel and antennomeres with minute, sparse, slightly conspicuous yellowish-white pubescence; antennomeres III–VIII with a few short, erect, thick dark setae, only ventrally in III–VI, dorsally and ventrally in VII–VIII; antennal formula (ratio) based on length of antennomere III: scape = 0.98; pedicel = 0.10; IV = 0.97; V = 0.92; VI = 0.89; VII = 0.74; VIII = 0.75; IX = 0.72; X = 0.61; XI = 0.47.

Thorax. Prothorax 1.75 times wider than long; posterolateral angles not spiniform. Pronotum very finely, densely punctate, except transverse posterior area with coarse punctures; with moderately dense centro-longitudinal pale yellow pubescent band, fused with transverse pale yellow pubescent band close to posterior margin (widened toward posterolateral angles); with moderately large yellowish-brown pubescent macula on each side of posterior half, and entire sides of anterior half (projected toward center on anterior third); remaining surface with brownish pubescence. Sides of prothorax with moderately abundant light yellowish-brown pubescence not obscuring integument. Prosternum with abundant light yellowish-brown pubescence laterally, distinctly sparser toward central area. Prosternal process with minute brownish pubescence not obscuring integument. Mesoventrite with dense pale-yellow pubescence laterally, distinctly sparser toward central area; mesanepisternum with dense pale-yellow pubescence; mesepimeron with pale-yellow pubescence sparser than on mesanepisternum; metanepisternum and sides of metaventrite with dense pale-yellow pubescence; remaining surface of metaventrite with pubescence of same color, but somewhat sparser. Scutellum with yellowish-brown pubescence on centrobasal area, not obscuring integument, with sparse yellowish-white pubescence close to margins. Elytra. Moderately coarsely abundantly punctate on basal third, gradually finer, sparser toward apex; elytral apex obliquely truncate; pubescence mostly brownish, partially obscuring integument, except pale-yellow pubescent bands and spots: arched band on center of dorsal quarter, not reaching anterior margin; longitudinal band from anterior margin to near middle of elytron, basally distinctly arched, arched close to scutellum, less so toward its apex, moderately abruptly widened near its midlength, then gradually narrowed toward its apex; zig-zag band dorsally on basal half, internally fused with the former band; short, oblique band laterally on anterior quarter; wide band on inclined area of basal quarter, gradually denser toward its apex; rounded spot on each side near middle of elytra; J-shaped pubescent band on about posterior quarter, denser, widened on its basal area, narrowed centrally, sparser on its distal area; rounded spot on each side of posterior quarter. Legs. Femora with yellowish-brown pubescence partially obscuring integument; profemora fusiform; mesofemora pedunculate-clavate; metafemora gradually widened from base to apex. Tibiae with yellowbrown pubescence partially obscuring integument, darkened on dorsodistal quarter of mesotibiae; mesotibiae with short, thick, abundant suberect black setae dorsally on distal third; metatibiae with short, thick, sparse suberect black setae dorsally and laterally. Metatarsomere I 1.35 times longer than II–III together.

Abdomen. Ventrites with pale-yellow pubescence slightly denser laterally, except glabrous distal area of I–IV, and basal area of V; distal margin of ventrite V widely, distinctly concave.

Dimensions (mm). Total length, 9.50; prothoracic length, 1.55; anterior prothoracic width, 1.85; posterior prothoracic width, 2.65; humeral width, 2.95; elytral length, 6.80.

Type material. Holotype male from COLOMBIA, Magdalena: road Minka-Cerro Kenedy (11º07’31”N / 75º06’07”W; 1000 m), 7-8.VI.2018, V. Sinyaev col. ( MZSP).

Remarks. Lepturges (Lepturges) brechlini sp. nov. is similar to L. (L.) funereus Monné, 1976 ( Fig. 28 ), but differs by the elytral pubescence pattern, and by the posterolateral angles of the prothorax not spiniform. It also differs from L. (L.) amabilis Bates, 1863 ( Fig. 26 ) by the elytral pubescence pattern, and by the pale-yellowish color of this pubescence (grayish in L. (L.) amabilis ). Lepturges (Lepturges) brechlini can be separated from L. (L.) hahneli Gilmour, 1959 ( Fig. 27 ) by the elytral pubescence pattern, and shorter antennae (2.45 times elytral length in the new species, about 3 times elytral length in male of L. (L.) hahneli ). Lepturges (Lepturges) brechlini resembles L. (L.) perelegans Bates, 1863 by the similar pattern of the elytral pubescence, but differs by the elytra slightly longer than 4 times the prothoracic length (slightly longer than 3 times in L. (L.) perelegans ).

Etymology. The new species is dedicated to Ronald Brechlin ( Germany), saturniid and sphingid (Lepidoptera) specialist. Ronald has organized, financed and participated in numerous entomological expeditions in Central and South America over the last few decades.
