description: Xenocona queros sp. nov.
(Fig. 3)
Description. Male. Integument mostly dark brown, with some areas darker; clypeus, labrum, and palpomeres yellowish brown; coxae, prosternum, meso- and metaventrite dark brown; ventrites light brown with posterior margins dark brown; basal half of scape dark brown, remaining surface gradually lighter toward apex; pedicel and antennomeres III–XI dark brown. Elytra dark brown on anterior half, gradually lighter toward apex. Femora light brown, peduncles dark brown.
Head. Frons and vertex finely punctuate, with sparse yellowish pubescence. Genae with yellowish gray pubescence. Postclypeus glabrous laterally, distinctly pubescent centrally. Labrum with golden semidecumbent setae and with dense yellowish pubescence close to anteclypeus. Upper eye lobes with eight rows of ommatidia; distance between them about 1.5 times width of one upper lobe. Lower lobes, in lateral view, about twice the height of the gena; in frontal view, distance between them about 1.5 times width of a lower lobe.Antennae surpassing elytral apex at antennomere VIII; scape gradually widened from base to apical fifth, then slightly narrowed toward apex, dorsal surface with golden pubescence and some glabrous areas; apex of antennomere III with internal projection, rounded apically; antennomeres III–VII with basal ring and medial area of golden pubescence. Antennomeres VIII–XI with golden pubescence on basal third. Antennal formula based on length of antennomere III: scape = 0.90; pedicel = 0.13; IV = 0.56; V = 0.43; VI = 0.36; VII = 0.32; VIII = 0.32; IX = 0.31; X = 0.31; XI = 0.31.
Thorax. Prothorax 1.5 times wider than long; anterolateral tubercles with blunt apex and medial tubercles with subacute apex. Pronotum with three tubercles, two antemedian, elevated, and one centroposterior, less elevated; with four black pubescent spots near posterior margin; anterior margin with transverse row of fine punctures; posterior third with coarser punctures. Prosternum with whitish pubescence; prosternal process about 1/10 width of procoxal cavity; mesoventrite with dense whitish pubescence; mesanepisternum and mesepimeron with whitish pubescence; central area of metaventrite with dense and moderately long yellowish setae. Scutellum with black pubescence and a longitudinal band of yellow pubescence, posterior margin strongly emarginate. Elytra. Surface with greenish pubescence and a few golden setae laterally, tufts of yellowish setae, and grayish white pubescence toward apical third, denser near V-shaped black areas; apex with yellowish-brown pubescence. Humerus rounded, slightly projected forward; longitudinal centrobasal crest slightly elevated and with semierect black setae dorsally; sides of posterior third convergent. Punctation fine on anterior third, finer on central region and not visible on posterior half. With some tubercles less elevated toward apex. Each elytron with longitudinal band interrupted and V-shaped on posterior third. Legs. Coxae with dense whitish pubescence; pro-, meso-, and metafemora strongly pedunculate-clavate, with whitish pubescence; tibiae with dense yellowish-brown pubescence except some areas with black pubescence.
Abdomen. Ventrites with slightly dense whitish pubescence; posterior margin of ventrite 5 strongly emarginated medially.
Dimensions (in mm). Total length, 8.3; prothorax length, 1.3; greatest width of prothorax, 2.0; anterior width of prothorax, 1.5; posterior width of prothorax, 1.7; humeral width, 2.7; elytral length, 6.5.
Type material. Holotype male from PERU, Cusco: San Pedro (Trocha union, 13°06'38.2"S, 71°36'18.5"W, 3,271 m), 17.III.2023, Y. Carmona & C. Stefan leg., LepiLED light trap (MUBI).
Etymology. Noun in apposition. In tribute to the Quechua community of Queros, recognized as the guardians of the wisdom of the Andes.
Remarks. Xenocona queros sp. nov. can be differentiated from its congeneric species by the posterior margin of the scutellum strongly emarginated and by an interrupted V-shaped black pubescent band on the posterior third of elytra. The new species is similar to X. chulumani Santos-Silva & Monné, 2023, but it is differentiated by the margins of elytra converging toward the posterior third and by the semi-erect blackish setae on the basal crest. In X. chulumani, the elytra converge near the posterior quarter and the setae on the basal crest are yellowish brown.
