Nappella antonkozlovi Santos-Silva , Nascimento & Drumont, sp. nov.

( Figs. 9-12 )

Description: Male. Color. Integument mostly black; basal half of antennomere III, basal third of IV, and basal quarter of V‑VI light brown.

Head: Frons coarsely, abundantly punctate; with yellowish‑brown pubescence not obscuring integument, denser laterally and toward antennal tubercles, interspersed with long, erect dark‑brown setae. Area between antennal tubercles and upper eye lobes coarsely, abundantly punctate; with yellowish‑brown pubescence not obscuring integument, interspersed with a few long, erect dark‑brown setae. Remaining surface of vertex and area behind upper eye lobes nearly smooth; with yellowish‑brown pubescence partially obscuring integument close to punctate area of vertex and upper eye lobes, sparser toward prothorax on center of vertex, nearly absent toward prothorax behind upper eye lobes; with a few long, erect dark‑brown setae close to upper eye lobes. Area behind lower eye lobes moderately finely punctate close to eye, smooth toward prothorax except slightly elevated, longitudinal carina at about middle; with yellowish‑brown pubescence nearly obscuring integument close to eyes, glabrous toward prothorax; with a few long, erect, dark‑brown setae near inferior side of eye. Genae minutely, transversely striate‑punctate; with sparse yellowish‑brown pubescence. Antennal tubercles moderately elevated; minutely, densely punctate; with moderately dense yellowish‑brown pubescence not obscuring integument, interspersed with long, erect dark‑brown setae. Median groove distinct between antennal tubercles and upper eye lobes. Postclypeus with punctures as on frons on wide central area close to frons, smooth toward anteclypeus and laterally; with yellowish‑white pubescence partially obscuring integument on punctate area, sparser toward anteclypeus, glabrous laterally; with a few long, erect dark‑brown setae laterally on punctate area. Labrum coplanar with anteclypeus at posterior ⅔, inclined at anterior third; finely, moderately abundantly punctate; with yellowish‑brown pubescence not obscuring integument, interspersed with long, erect, thick yellowish setae; with fringe of yellow setae at anterior margin. Gulamentum strongly inclined anteriorly; with sparse yellowish‑brown pubescence on inclined area, glabrous on remaining surface. Distance between upper eye lobes 0.16 times length of scape; in frontal view, distance between lower eye lobes 0.63 times length of scape. Antennae (missing antennomeres VII‑XI of both antennae; right scape damaged) about as long as elytra, apex of antennomere VI almost reaching distal third of elytra. Antennal formula (ratio) based on length of antennomere III: scape = 0.87; pedicel = 0.14; IV = 0.94; V = 0.83; VI = 0.77.

Thorax: Prothorax 1.4 times wider than long (including lateral tubercles). Pronotum coarsely, abundantly, partially confluently punctate throughout; with yellowish‑brown pubescence not obscuring integument slightly denser on longitudinal band on center of posterior half; with long, erect, sparse yellowish‑brown setae throughout. Sides of prothorax with pubescence and sculpturing as on pronotum. Prosternum coarsely, moderately sparsely, deeply punctate except on sulcate area close to anterior margin; with yellowish‑white pubescence not obscuring integument except glabrous area close to anterior margin. Central area of prosternal process narrower than 0.1 times width of procoxal cavity. Ventral side of meso‑ and metathorax moderately coarsely and abundantly punctate except nearly smooth central area of metaventrite; with yellowish‑white pubescence not obscuring integument. Mesoventral process about 0.4 times width of mesocoxal cavity. Scutellum nearly smooth, with short, sparse, decumbent yellowish‑brown setae. Elytra: Coarsely,abundantly punctate throughout; with yellowish‑brown pubescence not obscuring integument, interspersed with long, erect, thick, moderately abundant dark setae throughout. Legs: Femora with yellowish‑white pubescence not obscuring integument, interspersed with a few long, erect dark setae. Protibia moderately abruptly widened at distal third; meso‑ and metatibiae slightly, gradually widened toward apex; with bristly yellowish‑brown setae interspersed with long, erect dark setae.

Abdomen: Ventrites with yellowish‑white pubescence not obscuring integument, gradually more yellowish‑brown toward apex of V; apex of ventrite V truncate, very slightly emarginate centrally.

Dimensions (mm): Total length, 9.45; prothorax: length, 1.50; anterior width, 1.60; posterior width, 1.65; maximum width (between apices of lateral tubercles), 2.05; humeral width, 2.85; elytral length, 6.85.

Type material: Holotype male from PERU, Junín: near San Ramón (2,100 m; 11°5.26’S, 76°24.3”W), 01‑02.XII.2016, V. Sinyaev col. ( MZSP, former AKPC).

Etymology: The new species is named to honor of Anton Olegovich Kozlov,who sent the specimens for study, and donated the holotype for the MZSP collection.
