Nocalusa prodigiosa , sp. nov. ( Figs 1–7 )

Description. Female. Integument mostly metallic violaceous with greenish reflexions (violaceous areas more brownish depending on angle of light source); sides of postclypeus yellowish brown; antennae violaceous except scape with reddish brown with violaceous areas; elytra metallic dark khaki; femora yellowish brown, violaceous on narrow distal region, except left mesofemora nearly entirely violaceous; tibiae yellowish brown, slightly violaceous basally; tarsomeres I–IV brown, and tarsomere V reddish brown.

Head. Dorsal and lateral surfaces moderately coarsely, densely punctate, slightly sparser toward ventral side of area behind lower eye lobes, partially confluent between antennal tubercles and behind part of upper and lower eye lobes; with moderately short, erect, sparse pale yellow setae, slightly more abundant on some areas. Genae with punctures sparser, finer than on frons and vertex; with short, decumbent, sparse yellowish setae. Gulamentum moderately coarsely rugose-punctate throughout; with short, erect, moderately abundant yellowish setae. Distance between upper eye lobes 0.65 times length of scape; in frontal view, distance between lower eye lobes 1.60 times length of scape, in ventral view, distance between lower eye lobes 1.90 times length of scape. Antennae 1.4 times elytral length; scape with short, decumbent, sparse yellowish setae dorsally, longer ventrally; antennomeres glabrous except minute, sparse setae on basal segments; antennal formula (ratio) based on length of antennomere III: scape = 0.62; pedicel = 0.14; IV = 0.77; V = 0.69; VI = 0.64; VII = 0.59; VIII = 0.48; IX = 0.44; X = 0.38; XI = 0.47.

Thorax. Pronotum with long, erect, sparse yellowish setae, more abundant laterally, especially close to antero- and posterolateral angles. Prosternum with long, erect, moderately abundant yellowish setae; prosternal process gradually coarsely rugose-punctate toward apex; with long, erect yellowish setae, more abundant toward apex. Metaventrite finely, shallowly, sparsely punctate laterally, finely, densely punctate on central triangular area; with long, erect, sparse yellowish setae laterally, short, denser on central triangular area. Metanepisternum slightly more distinct punctate than in sides of metaventrite, with long, erect, sparse yellowish setae, slightly more abundant basally. Scutellum moderately coarsely punctate, gradually shallower, sparser toward apex; with short, erect, sparse yellowish setae, distinctly sparser toward apex. Elytral setae present only on circum-scutellar region. Femora with short, sparse yellowish setae, longer ventrally on basal half. Tibiae with short, sparse yellowish setae dorsally and laterally (more abundant than on femora), distinct more abundant ventrally, especially on distal third, where they are dense.

Abdomen. Ventrites I–IV finely, moderately sparsely punctate (sparser on I), except smooth transverse distal area; with long, erect, moderately sparse yellowish setae (sparser on I), except glabrous smooth area. Ventrite V slightly rugose-punctate basally, moderately coarsely, sparsely punctate laterally and distally, distinctly sparser on wide central area; with long, erect yellowish setae, basally more abundant than on ventrite IV.

Dimensions. Total length, 33.7; prothoracic length, 4.0; basal prothoracic width, 6.1; distal prothoracic width, 6.4; maximum prothoracic width, 7.3; humeral width, 8.0; elytral length, 15.6.

Type material. Holotype female from Bolivia, La Paz: Nor Yungas, no date indicated, Rainer Marx (collector?)(MZSP—former Petr Šváchaprivate collection). Obs.: The original label indicated Peru as country where the specimen was collected. However , Petr Švácha contacted the seller, Silvia Jakusch , a South American lady residing in Germany, who sent the following information: “ The animal is from N-Yungas , Bolivia. I got it from Rainer Marx, who immigrated to Lima last year.” We kept the original label, and added another with the correct information of the place and collector.

Etymology. Latin, prodigiosa = unnatural, strange (feminine); allusive to the abdominal shape.
