Adesmus culiki sp. nov.

( Figs. 51-54 )

Description: Holotype female: Coloration: Head mostly black;mouthparts reddish brown except for pale yellow palpomeres (apex of last palpomeres brownish); anteclypeus orangish brown on wide central area, black close to margins; antennae and mandibles black. Prothorax and ventral surface of meso- and metathorax black. Basal half of elytra reddish brown except for two large, subcir-

cular black maculae on center of dorsal surface, somewhat small, elongated black macula close to suture near posterior half, and elongated black macula on center of sides; posterior half black; limit between reddish-brown and black areas irregular. Legs orangish brown, except for dark brown tarsal claws.Ventrites black.

Head: Proportionally large, slightly wider than prothorax. Frons finely, somewhat sparsely punctate (punctures sparser centrally close to clypeus); with minute, nearly indistinct yellowish-brown pubescence, with a few long, erect setae of same color close to eyes.Vertex and area behind upper eye lobes finely rugose-punctate (less so centrally on vertex close to prothorax); with yellowish-brown pubescence not obscuring integument (nearly indistinct depending on angle of view; brownish depending on light intensity); with a few long, erect brownish setae close to eyes. Area behind lower eye lobes distinctly tumid close to eye; finely punctate (punctures coarser than on vertex); with dense silvery pubescence on tumid area (more golden depending on light angle and intensity). Genae slightly shorter than lower eye lobe; finely punctate close to eye, micropunctate on remaining surface, except for smooth apex; with yellowish-brown pubescence not obscuring integument, except for glabrous smooth area; with a few short,erect brownish setae interspersed toward posterior area. Antennal tubercles moderately elevated; densely micropunctate, with fine sparse punctures interspersed; pubescence as on frons, with a few long, erect brown setae interspersed on frontal base. Postclypeus finely, sparsely punctate on wide central area, smooth laterally; punctate area with pubescence as on frons, and smooth areas glabrous; with one long, erect brown seta on each side of wide central area. Labrum coplanar with anteclypeus at posterior ⅔, oblique at anterior third; smooth close to anteclypeus and on anterior third, somewhat coarsely punctate between these two areas; with long, sparse, erect brownish setae on punc- tate area. Distance between upper eye lobes 0.41 times length of scape (0.28 times distance between outer margins of eyes); in frontal view, distance between lower eye lobes 0.94 times length of scape (0.63 times distance between outer margins of eyes). Antennae 2.0 times elytral length, reaching elytral apex at posterior fifth of antennomere VII. Scape, pedicel and antennomeres with yellowish-white pubescence not obscuring integument, slightly yellowish toward distal segments; scape, pedicel and antennomeres III-VIII with long, erect brownish setae ventrally (gradually shorter and sparser toward VIII, sparser on scape and pedicel); dorsal apex of antennomeres III-X with a few somewhat short, erect brownish setae. Antennal formula (ratio) based on length of antennomere III: scape = 0.65; pedicel = 0.09; IV = 0.62;V = 0.50; VI = 0.47;VII = 0.41;VIII = 0.38; IX = 0.35; X = 0.32; XI = 0.31.

Thorax: Prothorax slightly wider than long;sides sinuous, with rounded gibbosity about middle. Pronotum oblique from anterior margin to posterior quarter, then somewhat abruptly sloped and becoming flat toward posteri- or margin; carina-shaped centrally from anterior margin to posterior quarter (slightly more distinctly centrally); with dense silvery pubescence obscuring integument (more yellowish depending on light intensity and angle source), except for brownish pubescence not obscuring integument on each side of anterior quarter, slightly more yellowish on central area of anterior quarter (especially depending on angle of view), dark pubescence not obscuring integument centrally, and subelliptical area with brownish pubescence not obscuring integument on each side of central area (extended to sides of prothorax). Sides of prothorax with dense silvery pubescence,gradually more yellowish brown toward ventral surface; with a few long, erect brownish setae interspersed. Prosternum coarsely, sparsely punctate; with abundant grayish-white pubescence, but not obscuring integument; prosternal process with yellowish pubescence. Mesoventrite coarsely punctate; nearly glabrous centrally, with yellowish pubescence laterally. Mesanepisternum with dense grayish-white pubescence; mesepimeron with dense yellowish-brown pubescence, longer than on mesanepisternum. Mesoventral process with yellowish pubescence not obscuring integument; sides flap-shaped near apex. Metanepisternum with dense grayish-white pubescence, yellower basally and close to superior margin. Metaventrite with dense grayish-white pubescence laterally, and dense golden pubescence on triangular central area.Scutellum with dense yellowish pubescence. Elytra: Somewhat coarsely, abundantly punctate on basal half, nearly smooth on posterior half; apex obliquely truncate (almost uniformly rounded); reddish-brown basal half of elytra with silvery pubescence, distinctly denser on wide band along suture, appearing to be yellower due to the integument color, especially depending on angle of view, dorsally interspersed with irregular areas with short golden pubescence, laterally with distinct, oblique golden pubescent band starting on humerus and involving de black macula; black maculae on basal half with yellowish-white pubescence not obscuring integument, appearing to be darker due to the integument color, denser on anterior macula; lateral black macula with golden pubescence not obscuring integument; anterior region of posterior half with minute yellowish-white pubescence distinctly exposing integument; posterior third with dense white pubescence. Legs: Femora with short yellowish pubescence not obscuring integument. Tibiae with yellowish pubescence, sparser on protibiae, with long, erect yellowish setae interspersed.

Abdomen: Ventrite I with dense grayish-white pubescence obscuring integument; ventrites II-V with minute grayish-white pubescence, abundant but not obscuring integument (slightly distinct depending on angle of view), denser and longer laterally, especially on IV and V. Posterior area o ventrite V with long, erect, somewhat sparse dark setae; posterior margin concave.

Dimensions in mm: Total length,17.20;prothoracic length, 3.00;anterior prothoracic width,3.60;posterior prothoracic width, 3.45; humeral width, 4.75; elytral length, 11.20.

Type material: Holotype female from BRAZIL, Espírito Santo: Aracruz , 19°49′02″S, 40°10′00″W, 08.XII.1995, J.A.C. Simões col. ( MZSP, formerly SSA).

Etymology: The new species is dedicated to Mark Paul Culik, an American entomologist who has been working for 20 years on a voluntary basis at Instituto Capixaba de Pesquisa Assistência Técnica e Extensão Rural (Incaper, Expírito Santo, Brazil).

Remarks: Adesmus culiki is similar to A. seabrai Lane, 1959 ( Fig. 55 ), also known only from the Brazilian state of Espírito Santo, by the black macula on pronotum and basal half of the elytra, and color of the legs, but differs: head lacking dense white pubescence (present in males and females of A. seabrai ); posterior third of the elytra entirely with white pubescence (with on large area without dense white pubescence dorsally and laterally on posterior half, sometimes fused apically, in A. seabrai ); area of elytra after middle with wide region with slightly conspicuous pubescence (absent in A. seabrai ). Chromatic gender dimorphism was already reported in Hemilophini : Phoebe ornator (Tippmann, 1960) ( Perger et al., 2017) .However,even in large series of P.ornator the pubescence on dorsal surface of the elytra is nearly identical in males and females. Furthermore, the holotype of A.seabrai is a female and does not show chromatic differences with males of the species, as well as the 27 specimens (males and females) examined.
