Paranisopodus antonkozlovi sp. nov.

( Figs 26–31 )

Description. Male. Integument mostly black; antennomere IV dark reddish brown except blackish basal and distal areas; antennomere V reddish brown on basal half, gradually blackish toward apex; antennomere VI mostly reddish in left antenna, entirely blackish in right antenna; antennomere VII entirely blackish (missing in left antenna); anten- nomere VIII blackish basally, gradually dark reddish brown toward apex (missing in left antenna); lateral tubercles of pronotum dark brown; elytra gradually dark brown toward apex; metatibiae slightly dark reddish brown on wide central area (more dark brown depending on light intensity); metatarsomere I reddish brown basally, yellowish brown on wide central area, blackish on apex.

Head. Frons very finely, densely rugose-punctate; tawny pubescent but not obscuring integument. Vertex and area behind upper eye lobes with sculpturing and pubescence as on frons except moderately deep depression between antennal tubercles and upper eye lobes smooth and glabrous inside; with a few long, erect brownish setae close to eye. Area behind lower eye lobes with tawny pubescence on area close to eye, nearly glabrous toward prothoracic margin (this latter area gradually widened toward ventral surface); with a few long, erect, brownish setae close to eye. Genae, close to eyes with moderately sparse tawny pubescence, slightly, gradually sparser toward glabrous apex; with one long, erect brownish setae ventrally. Antennal tubercles with sculpturing and pubescence as on frons (pubescence sparser dorsally). Median groove distinct from clypeus to prothoracic margin. Postclypeus with pubescence as on frons on wide central area, glabrous laterally; with long, erect dark-brown seta on each side of wide central area. Labrum at posterior 3/4 coplanar with anteclypeus, inclined at anterior quarter; with tawny pu- bescence interspersed with a few long, erect, dark-brown setae on coplanar area. Gulamentum smooth, glabrous on wide posterior area, depressed, minutely punctate, with very short and sparse tawny pubescence on narrow anterior area; with a few long, erect brown setae in anterior margin. Distance between upper eye lobes 0.30 times length of scape; in frontal view, distance between lower eye lobes 0.62 times length of scape. Antennae (missing antenno- meres VII–XI in left antenna; missing antennomeres IX–XI in right antenna) 1.45 times elytral length, reaching ely- tral apex at distal fifth of antennomere VII. Scape with tawny pubescence obscuring integument; with a few short, erect, thick dark setae posteriorly in ventral surface. Antennomere III with tawny pubescence obscuring integument (more brown in some areas) except distal fifth with darker, shorter, less conspicuous pubescence; antennomere IV with dark, slightly conspicuous pubescence basally and in distal quarter, tawny, obscuring integument on remaining surface; remaining antennomeres with pubescence nearly inconspicuous. Antennal formula (ratio) based on length of antennomere III: scape = 0.93; pedicel = 0.13; IV = 0.78; V = 0.56; VI = 0.43; VII = 0.40; VIII = 0.34.

Thorax. Sides with very large tubercle, gradually widened from about apex of anterior third of prothorax to slightly after middle, slightly inclined inward from this point to posterior fifth, where it becomes abruptly perpendicular to the margin of prothorax. Pronotum with large, elevated, elongate tubercle each side, from anterior fifth to posterior quarter, with rounded dorsal surface; with another smaller tubercle centrally, from slightly after middle to posterior quarter, with narrow, slightly carina-shaped dorsal surface; coarsely, moderately abundantly punctate except smooth tubercles; with dense tawny pubescence laterally, sparser centrally (except glabrous cen- tral tubercle), yellowish-white, sparser centrally on posterior quarter, white, very sparser on narrow central area close to anterior margin, brownish, very short, slightly conspicuous on lateral tubercles; with a few long, erect dark setae close to posterolateral angles. Sides of prothorax with tawny pubescence obscuring integument, less so anteriorly and posteriorly. Prosternum with dense yellowish pubescence laterally, yellowish-white, sparse centrally, except glabrous narrow anterior area. Prosternal process with yellowish-white pubescence not obscuring integument, slightly denser than in central area of prosternum, except distal area sparsely pubescent. Mesoventrite with sparse yellowish-white pubescence (more whitish depending on light intensity); mesanepisternum with dense tawny pubescence; mesepimeron with sparse tawny pubescence. Metanepisternum and sides of metaventrite with dense tawny pubescence, gradually yellowish-white, less dense toward central area of metaventrite; metaventrite without tubercles, with coarse, moderately deep punctures centrally, some of them with anterior margin slightly elevated. Scutellum with tawny pubescence nearly obscuring integument. Elytra. Centrobasal crest elevated, moderately wide, with rounded, glabrous tubercles dorsally, gradually fused toward posterior area; with distinct, moderately small, elongate tubercle after midlength; with two slightly defined carina dorsally, fused at distal third (together, slightly carina-shaped in this area); humeri projected forward; elytral apex obliquely truncate; coarsely, abundantly punctate on basal half, gradually finer, sparser toward apex; punctures between central basal crests with anterior margin elevated; laterodorsal area near humeri moderately scabrous. Pubescence as follows: dense, yellowish ba- sally; tawny on remaining anterior half, except moderately scabrous in laterodorsal area, irregular area in inclined area, and subcircular, sparse areas dorsally with minute, sparse brownish pubescence; posterior half with yellowish pubescence partially obscuring integument (this area limited anteriorly by tawny pubescence forming an indistinct V), irregularly interspersed with minute, sparse brownish pubescence; with rather sparse short, erect, dark setae throughout. Legs. Femora pedunculate-clavate, meso- and metafemora more distinctly so; peduncle slightly arched, more so in metafemora; apex of metafemora moderately surpassing elytral apex; with tawny pubescence partially obscuring integument dorsally and laterally; with minute, sparse, slightly conspicuous tawny pubescence ventrally. Protibia, in side view, arched, interior apex distinctly projected; meso- and metatibia straight, longitudinally sulcate dorsally; with tawny pubescence partially obscuring integument, distal half of metatibiae more sparsely pubescent. Metatarsomere I 2.5 times longer than II–III together.

Abdomen. Sides of ventrites I–IV with tawny pubescence partially obscuring integument; remaining surface with grayish-white pubescence not obscuring integument, except glabrous, narrow centrodistal area. Ventrite V with sparse grayish-white pubescence; distal margin concave.

Dimensions (mm). Total length, 10.60; prothoracic length, 1.75; anterior prothoracic width, 2.00; posterior prothoracic width, 2.50; maximum prothoracic width (between apex of lateral tubercles), 2.95; humeral width, 4.10; elytral length, 7.60.

Type material. Holotype female from COLOMBIA, Valle del Cauca : near El Quremal ( PN Farallones de Cali ; 3º31’’43”N / 76º44’00”W; 1500 m), 8.IV.2017, Sinyaev & Pinilla col. ( MZSP).

Remarks. Paranisopodus antonkozlovi sp. nov. resembles females of P. heterotarsus , but differs as follows: Scape longer and narrower ( Fig. 26 ); lateral tubercle of the prothorax not spined posteriorly ( Fig. 30 ); metaventrite without oblique row of tubercles ( Fig. 27 ); and metatarsomere I bicolorous ( Fig. 26 ). In males of P. heterotarsus , the scape is shorter and slightly wider ( Figs 17, 23 ), lateral tubercles of the prothorax are distinctly spined posteriorly ( Fig. 31 ), metaventrite with distinct oblique row of tubercles ( Fig. 18 ), and metatarsomere I unicolorous ( Fig. 17, 23 ). It differs from P. hovorei Monné & Monné, 2007 (see photograph of the holotype at Bezark 2018), by the lateral tubercles of the prothorax with truncate apex (projected in P. hovorei ), and by the longer scape.

Paranisopodus antonkozlovi can be included in the alternative of couplet “3” from Monné & Monné (2017) (modified):

Etymology. The species is named in honor of Anton O. Kozlov, who sent the specimen for study and donated the holotype to the MZSP collection.
