Oreodera antonkozlovi sp. nov.

( Figs. 1–3 )

Description. Male. Integument dorsally dark-brown, blackish on head and central area of pronotum; blackish on sides of head and yellowish-brown centrally; anteclypeus and labrum yellowish-brown; mouthparts yellowishbrown; antennomeres dark reddish-brown dorsally, lighter ventrally and on base; ventrally dark reddish-brown, lighter on abdomen; tibiae with central region mostly reddish-brown, darker on base and apex; tarsi dark-brown.

Head. Frons and vertex minutely, densely punctate; with yellow, decumbent, abundant pubescence, not obscuring integument, interspersed with short, erect setae centrally on frons, distinctly longer close to eyes. Area behind upper eye lobes with pubescence as on vertex (this area with pubescence gradually narrowed toward lower eye lobes, gradually almost glabrous close to prothorax). Area behind lower eye lobes tumid, minutely, densely punctate close to eye, with shallow sulcus following the tumid area (punctures inside sulcus minute, slightly sparser than on tumid area), minutely, sparsely punctate between sulcus and prothorax; with band with abundant, yellow setae close to eye, glabrous between this band and sulcus, with minute, moderately abundant, yellow setae inside part of the sulcus, glabrous between sulcus and prothorax. Genae very minutely striate-punctate except smooth narrow area close to apex; with narrow band with yellow setae close to eye, glabrous close to apex, with minute, moderately sparse, decumbent, yellowish setae on remaining surface, mainly toward ventral side. Antennal tubercles with sculpture as on frons, mostly glabrous (setae were probably lost). Coronal suture distinct from clypeus to prothoracic margin. Gula smooth, glabrous. Submentum depressed, narrow, minutely, densely punctate, transversely striate on base; with short, abundant, yellowish setae, not obscuring integument, interspersed with some long, erect setae toward mentum. Postclypeus very narrow, coplanar with frons on basal half, sloped on distal half; anterior margin of coplanar area concave centrally; with short, moderately abundant, yellow setae centrally (interspersed with long, erect setae, mainly on sloped area), glabrous laterally. Labrum convex, minutely densely punctate on basal 2/3, smooth on distal third; with minute, decumbent, yellowish-white setae; with transverse band of sparse, thick, erect setae near smooth area (these setae darkened on basal half). Distance between upper eye lobes 0.25 times length of scape; distance between lower eye lobes in frontal view 0.65 times length of scape. Antennae 1.75 times elytral length, reaching elytral apex about middle of antennomere VIII. Scape sub-fusiform, with transverse sulcus on basal fifth, entirely surrounding the surface, deeper ventrally; with abundant, decumbent yellowish-white setae, not obscuring integument, interspersed with long, erect setae, mainly ventrally. Pedicel with yellowish-white setae, ventrally interspersed with long, erect setae. Antennomere III with wide, basal ring with yellowish-white setae, with narrow basal ring with yellowish-white pubescence, and with yellowish, slightly conspicuous pubescence, interspersed with yellowish-white setae centrally; ventral surface with long, erect setae. Antennomeres IV–XI with pubescence and setae as on III, except yellowish-white setae centrally, that is absent (setae on ventral side gradually shorter, sparser toward distal segment, mainly after VII). Antennal formula (ratio) based on antennomere III: scape = 0.70; pedicel = 0.22; IV = 0.86; V = 0.67; VI = 0.64; VII = 0.61; VIII = 0.56; IX = 0.56; X = 0.53; XI = 0.56.

Thorax. Prothorax almost twice wider than long, with large, blunt lateral tubercle. Sides with short, decumbent, abundant yellow setae, from pronotum to inferior side of lateral tubercle, partially obscuring integument, with wide, transverse band with short, very sparse ochraceous setae (distinctly exposing integument), followed by band with ochraceous, dense setae (partially obscuring integument), gradually yellowish-white toward ventral side. Pronotum with two large, conical, elevated tubercle at distal half (close to middle of pronotum), and another smaller tubercle, sub-conical, placed centrally on basal half; surface of pronotum coarsely, moderately sparsely punctate on basal half and between conical tubercles and distal margin (punctures slightly coarser at this latter area); central area with abundant, decumbent, dense yellow setae, except top of central tubercle with setae distinctly shorter and less conspicuous; area in front of anterolateral tubercles with short, moderately abundant, yellow setae (distinctly shorter, sparser than central region); area behind anterolateral tubercles with short, yellowish, sparse setae, distinctly more abundant toward sides of prothorax; anterolateral tubercles glabrous; lateral area behind anterolateral tubercles with long, erect, sparse setae (including behind lateral tubercles of prothorax). Prosternum and mesosternum with short, decumbent, abundant, yellowish-white setae. Mesepimeron, mesepisternum, metepisternum and metasternum with short, abundant, decumbent, yellow setae. Scutellum with short, decumbent, moderately abundant, yellow setae. Elytra. Triangularly, moderately gibbous on center of basal quarter; coarsely, abundantly punctate on basal half, gradually finer, sparser toward apex (punctures not tuberculate); sides with wide, dense band with yellowish-white pubescence from near humerus to apex (more yellow toward epipleura); with oblique projection from base to suture at level of apex of basal triangular gibbosity, following toward scutellum along suture (not reaching scutellum, narrower than lateral band); and with another projection from just before middle to center of disc (distinctly not reaching suture); remaining surface with distinctly sparser, finer, yellowish-white setae (more yellow along suture and anterior quarter); apex strongly obliquely truncate, making outer angle projected. Legs. Femora and tibiae with decumbent, abundant yellowishwhite setae (more brownish on distal quarter of tibiae).

Abdomen. Ventrites with short, decumbent, abundant, yellowish-white setae (slightly more yellow laterally), except small, sub-circular area at each side of each ventrite with distinctly sparser setae (together forming a row on each side of ventrite), and sub-rectangular area close to lateral margin of each ventrite, placed on basal half, also with distinctly sparser setae. Distal margin of ventrite V slightly concave.

Dimensions (mm). Total length (including mandibles), 12.15; prothoracic length, 2.45; anterior prothoracic width, 1.40; posterior prothoracic width, 1.55; widest prothoracic width, 1.60; humeral width, 2.10; elytral length, 8.20.

Type material. Holotype male from ECUADOR, Pichincha: Camping Bella Vista (0º0’41”S / 78º41’17”W; 2230 m), 19.XII.2012 - 07.I.2013, Sinyaev & Romanov leg. (MZSP).

Etymology. The new species is named after Anton Olegovich Kozlov, who sent and donated the holotype.

Remarks. Oreodera antonkozlovi resembles O. cretata Bates, 1861 and O. cretifera Pascoe, 1859 by the elytra with dense lateral band with whitish pubescence. It differs from both by the band extending from near humerus to apex, with projections toward suture (not reaching humerus nor involving apex, and without projections in both of these species). It also differs from O. cretata by the anterolateral tubercles of pronotum glabrous (pubescent in O. cretata ), and by the elytral apex strongly oblique (slightly oblique in O. cretata ). It can also be separated from O. cretifera by the absence of distinct tubercles on the basal half of elytra (present in O. cretifera ).
