Cleodoxus antonkozlovi sp nov.

( Figs 1–4 ).

Description male. Integument mostly brownish; head dark brown, almost black; mouthparts (except mandibles) yellowish brown; antennomeres III–V reddish brown, dark brown near apex; VI–X reddish-brown, gradually dark brown from distal third toward apex; XI entirely reddish brown; tubercles on pronotum dark brown; elytra with widened, transverse dark-brown band on anterior third; lateral carina and posterior areas of inner and outer carinae dark brown (glabrous areas); with some irregular brownish areas at posterior third; femora with yellowish-brown peduncles, claves brownish, irregularly dark brown ventrally; anterior half of tibiae brownish, gradually dark brown on distal half; tarsomeres I–II brownish, dark brown posteriorly.

Head. Frons densely microsculptured; with abundant yellowish pubescence nearly obscuring integument; vertex depressed (between anterior margin of upper eye lobes); area behind upper eye lobes glabrous (except close to eye); sides of head with dense yellowish pubescence, not reaching anterolateral margin of prothorax. Genae scarcely yellowish pubescent, apex rounded. Antennal tubercles abruptly elevated at basal half, distal half slightly flattened; surface with yellowish pubescence nearly obscuring integument. Median groove distinct from clypeus to anterior margin of prothorax. Postclypeus densely microsculptured, glabrous; with long, erect, sparse dark setae directed forward. Labrum with dense yellowish pubescence nearly obscuring integument; with a few long, erect, sparse black setae. Mandibles triangularly depressed at lateral base, with yellowish pubescence. Gulamentum smooth, glabrous; surface slightly, transversely striated anteriorly. Lower eye lobes about 2.5 times genal length; in front view, distance between lower eye lobes about three times maximum width of scape. Upper eye lobes with nine rows of ommatidia, separated by distance nearly equal to width of an upper eye lobe. Antennae about twice body length; reaching elytral apex at mid-length of antennomere VI. Scape gradually widened toward apex, slightly depressed ventrally at apex; surface with moderately dense yellowish pubescence, not obscuring integument; with long, erect, sparse black setae ventrally. Pedicel and remaining antennomeres with yellowish pubescence nearly obscuring integument; pedicel and antennomeres III–IV with long, erect, sparse black setae on inner side; remaining antennomeres with long, erect, black setae restricted to apex. Antennal formula based on antennomere III: scape = 0.85 pedicel = 1.00; IV = 0.95; V = 0.93; VI = 0.87; VII = 0.83; VIII = 0.91; IX = 0.93; X = 0.91; XI = 0.77.

Thorax. Prothorax about 1.8 times wider than long; lateral tubercle placed at middle, large basally and abruptly acute apically. Disc of pronotum with three elevated tubercles, two circular, parallel-sided, apically obtuse placed at anterior third, another elongate, postmedian; surface coarsely punctate (except on tubercles), punctures denser around tubercles, and finer between them; surface with abundant yellowish pubescence (except on tubercles), partially obscuring integument. Prosternum with dense yellowish pubescence, partially obscuring integument. Prosternal process about 0.4 times procoxal cavity diameter. Procoxal cavity closed behind. Mesoventrite densely pubescent; mesoventral process about as wide as half mesoventral cavity diameter; mesoventral cavity closed laterally. Metaventrite scarcely pubescent centrally; moderately densely pubescent laterally, partially obscuring integument. Mesanepisternum, mesepimeron, and metanepisternum with dense yellowish pubescence, nearly obscuring integument. Scutellum about 1.7 times wider than long, with dense yellowish pubescence nearly obscuring integument; posterior margin rounded. Elytra. About 4.9 times prothoracic length; longitudinal dorsal tubercle well-marked at anterior fifth; anterior third slightly elevated. Surface with lateral carina and two dorsal carinae; lateral carina starting at humeral angle, reaching posterior quarter; outer dorsal carina starting at humeral angle, slightly convergent toward suture at posterior sixth, not reaching suture; inner dorsal carina slightly elevated, starting at posterior margin of longitudinal tubercle, slightly arched, converging toward sides with the outer dorsal carina; area parallel to the inner dorsal carina (close to suture) slightly depressed. Elytral suture longitudinally sulcate; sides of elytra gradually, slightly convergent toward posterior quarter; posterior fifth more distinctly convergent toward apex; apex transversely truncate, triangularly projected at outer angle. Surface of anterior eighth abundantly, coarsely punctate, punctures evenly distributed; sparser and shallower toward apex. Humerus strongly granulate-punctate laterally. Pubescence as follow: area around scutellum, along suture and around posterior glabrous areas of dorsal carinae with whitish pubescence; remaining areas with yellowish pubescence sparsely interspersed with whitish pubescence except posterior third with longitudinal, irregularly sinuous dark-brown bands. Legs. Coxae with moderately dense whitish pubescent; Trochanter with some erect, elongated dark setae; femora strongly pedunculate and clavate, meso- and metapeduncles slightly arched, clavae with moderately dense whitish pubescence; mesofemora with peduncle about 0.4 times mesofemoral length; metafemora with peduncle about half metafemoral length. Tibiae with moderately dense yellowish-white pubescence, denser toward apex; with erect, elongated dark setae ventrally; protarsomere I slightly longer than II; mesotarsomere I about as long as II + III; metatarsomere I longer than II + III.

Abdomen. Surface with moderately dense yellowish-white pubescence; ventrite I, from intercoxal process, about twice II length; II–IV subequal in length; V trapezoidal, apex strongly notched.

Dimensions (in mm), holotype male/ paratypes. Total length, 9.9/8.5-9.2; prothorax length, 1.5/1.3-1.4; greatest width of prothorax, 2.6/2.2-2.3; anterior width of prothorax, 1.8/1.5-1.6; posterior width of prothorax, 2.1/ 1.9-2.0; humeral width, 3.5/3.0-3.2; elytral length, 7.1/6.2-6.8.

Type material. Holotype male from COLOMBIA, Magdalena (Municipio de Minca near Minca , 11°07’31”N 74°06’07”W, 1100m), 17-18. VII.2017, Sinyaev & Pinilla col. ( MZSP) ; paratype male same data as holotype ( MZSP); two paratype males from Cesar ( Sierra Nevada de Santa Marta (E), 8km N of Pueblo Bella, 10°30’57”N 73°34’26”W, 2700m), 13-16, VII.2017, Sinyaev & Pinilla col. ( AKPC) ; paratype male, 10-13.VII. 2016, Sinyaev & Pinilla col. (AKPC).

The coordinates 10°30’57”N 73°34’26”W point to the municipality of Fundación , Dept. Magdalena.

Etymology. The species is named to honor Anton Olegovich Kozlov, who kindly sent and donated specimens to the MZSP.

Remarks. Cleodoxus antonkozlovi sp nov. differs from C. tetralophus Monné & Monné, 2017 primarily by the pronotum entirely coarsely punctate (except on the tubercles), lateral tubercle of the prothorax abruptly acute apically, distal third of the elytra without granules (granules restricted to humerus), and slender body shape. Cleodoxus tetralophus has the punctures of the pronotum restricted to one row at the posterior margin, the lateral tubercle of the prothorax is slightly elevated and obtuse apically, and the distal third of the elytra has multiple granular protuberances. The new species differs from C. carinatus (White, 1855) by the scape ventrally depressed at apex, lateral tubercle shape, large basally and abruptly acute posteriorly, and elytral apex transversely truncate, slightly triangularly projected at outer angle. Cleodoxus carinatus has the scape not depressed ventrally at apex, the lateral tubercle of the prothorax is acute from the base, and the elytral apex is obliquely truncated with outer angle strongly projected in a spine. Furthermore, C. antonkozlovi sp. nov. can be easily differentiated from both by the absence of a circular blackened area in the posterior third of the elytra. Besides the morphological differences, the new species seems to be endemic to Sierra Nevada de Santa Marta ( Colombia), above 1,000 meters of altitude, since this area seems to be isolated in terms of the type of vegetation (fig. 9).
