description: Discomorpha (s. str.) giganteensis sp. nov.
Etymology
Named after its locus typicus, the city Gigante in Huila Province of Colombia.
Diagnosis
Very similar and close to Discomorpha putumayoensis sp. nov. described above. For distinguishing characters see diagnosis of that species.
Description
Length: male 13.2–13.4 mm, female 13.2 mm; width: male 12.9–13.4 mm, female 12.8; width of pronotum: both sexes 8.0– 8.3 mm, length of pronotum: both sexes 3.5–3.7 mm; length/width ratio: male 1.00–1.02, female 1.03; width/length ratio of pronotum: both sexes 2.24–2.31. Body in male and female moderately broad, in both sexes moderately converging posterad (Fig. 9, 10).
Head black with two small, round, red spots between eyes. Pronotum black with very dark green-blue metallic tint. Scutellum black. Elytral disc mostly red with dark metallic green-blue variable pattern, in all examined specimens pattern is well developed, beetles look distinctly maculate. Metallic are: whole postscutellar impressions and humeri, suture, interspaces along suture, sometimes forming broad, metallic band along suture, moderately broad band along lateral margin of elytra, four large spots on sides of disc, few interspaces in posterolateral part of disc, and 2–7 spots on explanate margin of elytra. Two spots on explanate margin, before mid length of elytra, tend to form transverse stripes. Antennal segments 1–5 yellowish to reddish-brown ventrally and black dorsally, segments 6–11 black. Ventrites and legs black.
Pronotum subtriangular, sides strongly converging anterad, lateral margins straight. Anterior margin shallowly emarginate, anterior corners obsolete. Top of disc with two shallow impressions. Disc dull, median smooth line runs from anterior margin of pronotum to 3/4 length of disc. Punctation of disc very fine and sparse. Whole surface covered by moderately long adherent hair.
Elytra broad, humeri in male regularly rounded, in female anterior margin of humeri on short distance almost straight, runs obliquely posterad. Elytra widest in anterior 1/4 length then in both sexes moderately converging posterad. Disc with large postscutellar tubercle (Fig. 11). Elytral profile behind the top of tubercle distinctly concave.
Postscutellar impressions distinct, bordered laterally by low fold, dull in anterior half and shiny on sides of elytral tubercle. Punctation of disc coarse, distinctly coarser than in Discomorpha putumayoensis sp. nov., dense, on sides of disc punctures almost touching each other, metallic interspaces form more or less distinct reticulation. Explanate margin of elytra impunctate, its surface dull. Elytra covered by pubescence. In female hairs erect, long and dense on whole surface of elytra, in male hairs distinctly shorter and sparser than in female, distinct and erect in humeral part of elytra, gradually shorter and semierect posteriorly, on slope hairs hardly visible. Apex of elytral epipleura with long, dense, erect pubescence.
Antennae long, distal part with long and dull segments 1.89–2.04 times longer than basal part with short and glabrous segments. Segments 3–5 approximately the same length. Segment 7 approximately 1.16–1.17 times as long as segments 5 and 6 combined. Ventrites without diagnostic characters. Male genitalia typical for the genus (Fig. 16, 17).
