Pedicel with yellowish pubescence not obscuring integument, and a few short, thick, decumbent dark setae ventrally; antennomeres III–XI with yellowish-white pubescence not obscuring integument; antennomeres III–IV with short, erect, thick, sparse dark setae ventrally; antennomeres V–VI with a few short, thick dark setae apically.

Antennal formula based on length of antennomere III:

– Scape = 0.80. – Pedicel = 0.10. – IV = 0.75. – V = 0.65. – VI = 0.60. – VII = 0.55. – VIII = 0.55. – IX = 0.55. – X = 0.50. – XI = 0.45.

Thorax. – Prothorax distinctly wider than long; sides slightly rounded on anterior third, tumid from this point to lateral tubercles, then abruptly narrowed to posterolateral angles; lateral tubercles with acute apex, located on posterior quarter. Pronotum minutely, densely punctate on anterior 3/4, with transverse row of coarse punctures and minute, sparse punctures interspersed on posterior quarter; with large brownish pubescent macula one each side of middle, not obscuring integument, from near anterior margin to posterior quarter; with three wide, longitudinal, dense yellowish-brown pubescent bands on anterior 3/4, fused along anterior margin, partially fused close to posterior quarter (lateral bands widened toward anterolateral angles); with irregular brownish pubescent macula laterally on central area; with moderately abundant yellowish pubescence on area of lateral tubercles; with yellowish pubescence not obscuring integument on posterior quarter, almost absent on coarsely punctate region; and with a few long, erect dark setae on area of lateral tubercles. Sides of prothorax with abundant yellowish-brown pubescence partially obscuring integument. Prosternum and prosternal process with abundant yellowish pubescence not obscuring integument, yellower on sides of prosternum; narrowest area of prosternal process 0.32 times procoxal width. Procoxae and mesocoxae with abundant, long yellowish-brown pubescence centrally, darker laterally. Mesoventrite with sparse yellowish-brown pubescence on wide central area, denser laterally; mesanepisternum, mesepimeron, metanepisternum and sides of metaventrite with dense yellowish-brown pubescence; central area of metaventrite with abundant yellowish-white pubescence. Scutellum with dense pubescence, yellowish-brown on anterolateral region, pale yellow on remaining surface.

Elytra. – Parallel-sided on anterior half, convergent on posterior half; apex obliquely truncate, with blunt outer angle; coarsely, abundantly punctate on basal half, anterior margin of punctures granulate on basal quarter, coarsely, sparsely punctate on posterior half (forming irregular rows along suture and laterally); with yellowish-brown pubescence on basal seventh, forming irregular projections posteriorly toward next pubescent band; with large, dense pale yellow pubescent macula from about anterior sixth to about middle, with anterior margin irregular and somewhat convex and posterior margin strongly dentate; with narrow, longitudinal, pale yellow pubescent band close to suture, from previous macula to apex; with elongate, V-shaped pale yellow pubescent band on side of dorsal surface, from large pubescent band on anterior half to posterior seventh; with longitudinal, slightly oblique pale yellow pubescent band dorsally, from sutural angle to before middle; with elongate, subelliptical pale yellow pubescent band dorsally, between V-shaped pubescent band and suture, located slightly after middle; and area close to epipleural margin with 6 - 9.

yellowish-brown pubescence from base to apex, more pale yellow toward apex.

Legs. – Femora pedunculate-clavate; with dense yellowish-brown pubescence partially obscuring integument. Tibiae with abundant yellowish pubescence partially obscuring integument, except posterior 2/3 of ventral surface of protibiae with bristly yellowish-brown pubescence, posterior third of ventral surface of mesotibiae and posterior quarter of metatibiae with yellowish-brown pubescence, and posterior third of dorsal surface of mesotibiae with bristly, both yellowish-brown and brownish pubescence.

Etymology. – Lepturges (Lepturges) caldensis sp. nov. is named for the Colombian province of Caldas, where the holotype was collected.

Remarks. – Lepturges (Lepturges) caldensis sp. nov. is similar to L. (L.) navicularis Bates, 1872 ( Fig. 10), but differs as follows: scape slender, reaching the base of the prothorax; antennomeres III–XI slender and unicolorous; punctures on the anterior region of the elytra granulate; and prosternal process about one-third the width of a procoxa. In L. (L.) navicularis , the scape is stouter and does not reach the base of the prothorax, antennomeres III–XI thicker and bicolorous, elytral punctures not granulate, and prosternal process almost laminiform centrally. Additionally the elytral pubescent pattern is different in these two species.It differs from females of L. (L.) onorei Santos-Silva, Nascimento, Botero & McClarin, 2021 ( Fig. 11), by the antennomere III distinctly longer than the scape (about as long as the scape in L. (L.) onorei ), antennomeres III–XI unicolorous (bicolorous in L. (L.) onorei ), punctures on the anterior region of the elytra granulate (not granulate in L. (L.) onorei ), prosternal process about one-third the width of a procoxa (very narrow in L. (L.) onorei ), and different elytral pubescent pattern.
