Pseudosparna antonkozlovi Santos-Silva & Nascimento , sp. nov.

( Figures 29–32 )

Description. Male. Integument mostly dark brown, almost black on some areas; anterior area of labrum reddish brown; pronotum with longitudinal brown band on each side, not reaching anterior margin; elytra with longitudinal brown band on each side of anterior half, brownish along suture (gradually lighter toward posterior quarter), yellowish brown on about posterior third (anterior margin of this area arched), except light reddish brown band close to apex; trochanteres orangish (more pale yellow depending on light intensity); profemora narrowly orangish on base (more pale yellow depending on light intensity); basal quarter of mesofemora, and basal eight of metafemora orangish (more pale yellow depending on light intensity).

Head. Frons finely, sparsely punctate; with abundant yellowish pubescence not obscuring integument. Area between antennal tubercles and upper eye lobes with dense, longitudinal yellow pubescent band along median groove; remaining surface with brownish pubescence not obscuring integument; remaining surface o vertex with brownish pubescence not obscuring integument, gradually shorter, less conspicuous toward prothoracic margin. Area behind and close to eyes with brownish pubescence not obscuring integument close to vertex, gradually yellower, wider toward lower eye lobes; remaining surface of the area behind upper eye lobes glabrous. Antennal tubercles with pubescence as on frons frontally, slightly brownish toward upper eye lobe. Median groove distinct from clypeus to area between upper eye lobes. Genae with sculpturing and pubescence as on frons except smooth, glabrous distal area. Postclypeus narrow, with sparse, bristly yellowish setae on wide central area, glabrous laterally. Labrum with decumbent yellowish setae not obscuring integument, interspersed with long, erect dark setae, and fringe of nearly golden setae on anterior margin. Distance between upper eye lobes 0.19 times length of scape; in frontal view, distance between lower eye lobes 0.37 times length of scape. Antennae 2.1 times elytral length, reaching elytral apex at apex of antennomere VI; with yellowish-white pubescence not obscuring integument, more conspicuous on scape; ventral surface of scape, pedicel, and antennomeres III–VI with long, erect dark setae, shorter, sparser toward VI; antennomeres VII–VIII with a few short, erect dark setae dorsally; antennal formula (ratio) based on length of antennomere III: scape = 1.05; pedicel = 0.10; IV = 0.82; V = 064; VI = 0.61; VII = 0.60; VIII = 0.60; IX = 0.59; X = 0.55; XI = 0.48.

Thorax. Pronotum moderately coarsely punctate on posterior quarter, and on each side of central area (more abundantly on posterior quarter); with a few long, erect dark setae on sides of posterior area; with brownish pubescence partially obscuring integument, except: wide, dense, longitudinal pubescent band on each side, from posterior margin to anterior quarter (more yellowish brown anteriorly); yellowish-white pubescent macula on each side of posterior area, close to yellow pubescent band. Sides of prothorax with brownish pubescence not obscuring integument on wide area close to pronotum, denser, yellowish (more whitish depending on light intensity) close to prosternum. Prosternum with yellowish pubescence (more whitish depending on light intensity), partially obscuring integument laterally, shorter, not obscuring integument centrally. Prosternal process with pubescence as on central area of prosternum, except denser, bristly pubescence at apex. Mesoventrite with yellowish pubescence not obscuring integument (more whitish depending on light intensity). Mesanepisternum, mesepimeron, and metanepisternum with yellowish-brown pubescence (more greenish-brown depending on light intensity), denser on metanepisternum. Metaventrite with yellowish pubescence not obscuring integument on wide central area (somewhat greenish depending on light intensity), yellowish white on remaining surface. Scutellum with brownish pubescence not obscuring integument. Elytra. Moderately coarsely, abundantly punctate on basal half, distinctly finer, sparser on posterior half; apex obliquely truncate, with outer angle distinctly spiniform, and sutural angle rounded; with long, erect, sparse dark setae throughout; pubescence as follows: dense yellow pubescent band on each side of basal half, narrowed at about its basal second quarter; yellow pubescent band along suture, from scutellum to posterior light area of elytra; entirely yellow on posterior light area; remaining pubescence brownish, slightly more yellowish-brown between yellow pubescent bands. Legs. Femora and tibiae with whitish pubescence not obscuring integument (more yellowish brown on dorsal surface of profemora); ventral surface of protibiae with bristly, black pubescence on posterior half; dorsal surface of meso- and metatibiae with thick, erect, abundant black setae on posterior half (more so in mesotibiae); meso- and metatibiae with moderately long, erect, sparse dark setae throughout. Metatarsomere I twice length of II–III together.

Abdomen. Ventrites with yellowish pubescence partially obscuring integument, except glabrous centroposterior area of III–IV; apex of ventrite V truncate, with outer sides distinctly spiniform.

Female. Differs from male only by the outer apical angles of abdominal ventrite V shortly spiniform.

Dimensions (mm), holotype male/ paratype female. Total length, 9.10/8.70; prothoracic length, 1.30/1.20; anterior prothoracic width, 1.15/1.20; posterior prothoracic width, 1.40/1.40; maximum prothoracic width, 1.70/1.70; humeral width, 2.10/2.10; elytral length, 6.80/6.90.

Type material. Holotype male ( MZSP), and paratype female ( AKPC) from COLOMBIA, Huila: Palestina (Parque Nacional Cueva de los Guácharos; 01º40’25”N / 76º13’29”W; 2200 m), 16-18.IV.2018, V. Sinyaev col.

Remarks. Pseudosparna antonkozlovi differs from all other species of the genus by the antennomere IV entirely dark (at least partially yellowish or whitish in the other species), and by the yellowish-brown posterior third of the elytra, covered with dense yellow pubescence (not so in the other species).

Etymology. The new species is named in honor of our friend Anton Olegovich Kozlov, third author of this work, for donating the holotype for the MZSP collection.
