Body ( Figs 1–4 ) elongate, 3.27 (3.10–3.62) times as long as pronotum width at base, slightly convex, without dorsal curvature; dorsally golden-green, occasionally bluish-green, elytra with poorly marked golden-bronze marginal stripe along entire length, ventrally golden-bronze to golden-red; antennal segments VI–XI fulvous, proximal segments and legs golden-green; body dorsally covered with short, semi-erect, white setae, ventrally with longer recumbent setae. Total length 14.2 (12.2–16.1) mm, width 4.4 (3.7–5.2) mm (n = 8: 4 ♁♁ 4 ♀♀).

Head ( Fig. 10 ) relatively narrow, moderately convex when seen from above ( Figs 1–2 ); frons flattened, without medial line or depression, with nearly straight, markedly convergent sides. Vertex with fine medial line, narrow, 1.65 (1.40–2.00) times as wide as transverse diameter of eye and 0.74 (0.70–0.81) times as wide as frons above antennal sockets. Eyes large, moderately convex, slightly or not protruding beyond head outline. Clypeus: lateral branches nearly completely reduced, not enclosing antennal sockets from below (sockets open); with narrow, deep, arcuate medial emargination anteriorly. Anteclypeus exposed, with medial groove. Frons with coarse reticulate-rugose sculpture of small, deep, irregular, umbilicate punctures without inner granules and poorly marked micropunctures; intervals narrower than diameter of puncture, forming slightly elevated transverse rugosities; covered with relatively long, semi-erect white setae. Antennae very long, in male 2.22 (2.09–2.31), in female 2.20 (2.05–2.32) times as long as height of eye; enlarged from antennomere V and bearing large sensory fossae ventrally from antennomere IV; antennomeres IV–X obtuselyserrate, much longer than wide; antennomere XI irregularly oval, 1.5–2.0 times as long as wide; antennomeres VI–XI partly or completely fulvous in both sexes.

Pronotum ( Figs 1–3 ) more or less bell-shaped with acute posterior angles protruding outward, slightly transverse, 1.43 (1.35–1.48) times as wide at base as long, widest at base; pronotal sides S-shaped. Аnterior margin feebly bisinuate, projecting forward, bordered with fine groove; basal margin slightly angularly protruding medially, nearly straight. Lateral carina fine, strongly incurved, S-shaped, entire, nearly reaching anterior angles. Pronotal surface flattened, with large, deep medial depression; prescutellar fossa poorly marked at base of medial depression, latero-basal depressions punctiform. Pronotal sides with ocellate sculpture of deep punctures with inconspicuous inner structure and elevated intervals; toward disc intervals merge, forming transverse rugae, disc covered with very coarse punctato-rugose sculpture. Sides with relatively long, recumbent, white setae; disc with inconspicuous, sparse, short setae. Anterior prosternal margin ( Fig. 4 ) straight, bordered with well marked, fine groove; prosternum weakly convex, covered with coarse punctato-rugose sculpture; prosternal process wide, slightly narrowing apically, covered with dense simple punctures. Hypomeron bearing dense, nearly alveolate sculpture. Scutellum entirely absent ( Figs 1, 2 ).

Elytra ( Figs 1–3 ) moderately elongate, 2.35 (2.22–2.44) times as long as wide at base, weakly convex; sides not widening at humeri, subparallel or slightly diverging toward posterior 1/3, then gently arcuately converging to apices; apices obtusely bidentate, with poorly marked sutural and angular marginal denticles, the later sometimes blunt; lateral margin slightly deflexed, epipleura poorly separated by indistinct carina; subhumeral lobe not covering metepisternum, bearing small denticle posteriorly; epipleural serrations inconspicuous, margin nearly smooth in posterior half. Strial punctures round or slightly elongate, separated in anterior half; in posterior half punctures merging and striae slightly sulcate; 2 nd stria short, reaching about 1/4–1/5 of elytral length. Intervals subequal, weakly convex or flattened, on disc about five times as wide as diameter of strial punctures; discal intervals with very fine, sparse uniseriate punctures, lateral intervals finely transversely rugulose; covered with fine, curved, uniseriate white setae, approximately as long as half of interval width. Elytra golden green, occasionally bluish-green, with indistinct golden-bronze marginal stripe along entire length, sometimes extending to pronotal sides.

Legs ( Figs 1–4 ). Femora and tibiae ventrally golden-green with bronzy sheen, tibiae dorsally copper-green, tarsi bluish; metacoxal plates ( Figs 3–4 ) with subparallel margins, posterior margin nearly straight, slightly emarginate laterally, without lateral tooth. Tibiae feebly widened toward apices; in male pro- and mesotibiae strongly curved ( Fig. 1 ), in female protibiae slightly curved, mesotibiae straight ( Fig. 2 ); metatibiae bearing comb of dense yellowish setae externally. Tarsomere I longest, equal to II and III combined; tarsomeres II–IV subequal, short; tarsomere IV with medial notch at anterior margin; tarsomere V relatively short, equal to III and IV combined, flattened and distinctly expanded toward apex; tarsal pads well developed on tarsomeres I–IV, on tarsomere I as long as tarsomere itself. Tarsal claws long, curved, simple, swollen at base.

Abdomen ( Figs 3–4 ) golden-green with coppery sheen medially changing to golden-red laterally; covered with dense simple punctures (intervals equal to 2–3 diameters of a puncture laterally and more than 3 diameters medially) and rather long semi-erect white setae which are denser on sides. Suture between ventrites I–II well marked, nearly straight. Anal ventrite obtusely rounded apically in both sexes.

Male. Aedeagus as in Figs 13–16 . Parameres dorsally with distinct longitudinal rugosity not extending to their apices ( Figs 13–14 ). Penis ( Figs 15–16 ) with very short (about 1/3 of entire length), sclerotized, obtuse apical part and very long (about 2/3 of entire length), nearly straight basal apophyses with curved apices.

Female. Ovipositor ( Fig. 27 ) of tubular type, relatively short, approximately 2.5 times as long as expanded apical part, with angularly emarginate apex and styli widely separated from each other.

Differential diagnosis. See under diagnosis of Svatactesis gen. nov. and Table 1 . Additionally, S. johanidesi differs from a single West-Palaearctic species of Polyctesini , Polyctesis rhois ( Fig. 5 ), as follows (see also BÍLÝ 1997): dorsal and ventral coloration different (in P. rhois nearly unicolorous); pronotum and elytra bearing distinct setae as long as half of width of elytral intervals (in P. rhois inconspicuous, nearly as long as diameter of punctures); sides of frons distinctly converging towards vertex (in P. rhois almost parallel sided or slightly converging, 0.94 (0.90–1.00) times as wide as frons above antennal sockets ( Fig. 11 )); antennae very long, antennomeres VI–XI fulvous (in P. rhois antennae much shorter, in male 1.63 (1.43–1.70), in female 1.32–1.66 times as long as vertical diameter of eye, unicolorous); pronotum more strongly transverse, rugosities very coarse, lateral carina complete (in P. rhois pronotum 1.17 (1.13–1.26) times as wide at base as long, transverse rugosities fine, lateral carina incomplete); aedeagus elongate, narrow ( Figs 13, 14 ), with longitudinal dorsal rugosities not extending to parameral apices, penis with very short sclerotised apical part and very long basal apophyses ( Fig. 15 ) (in P. rhois aedeagus much wider and shorter ( Fig. 17 ), dorsal rugosity extending to parameral apices (see BÍLÝ 1997: Fig. 5 ), penis with very long sclerotized apical part and very short basal apophyses ( Fig. 18 ); larvae develop in Quercus spp. ( Fagaceae ) (larvae of P. rhois develop in Rhus coriaria L. ( Anacardiaceae )).

Ecological information. Larvae of Svatactesis johanidesi develop in dead branches of Quercus spp. ( Fagaceae ) ( BÍLÝ 1997) in contrast to the known larvae of Polyctesis ( P. rhois and P. strandi Obenberger, 1934 ) and Bellamyina ( B. hunanensis (Peng, 1992)) whose larvae develop in the species of Anacardiaceae ( BÍLÝ 1997; VOLKOVITSH 2004; E. Kučera, pers. comm.). The only known larval host plant of Schoutedeniastes is Acacia gageana Craib (Fabaceae) (1 spec. of S. apicata (Waterhouse, 1882) from Dehradun, Uttarkhand, India (MNHN)). Adults of. S. birmanica (Théry, 1947) have been collected on the leaves of unidentified tree species of Fabaceae in Laos (V. Kubáň, personal communication).

Distribution. Turkey (Mersin) ( BÍLÝ 1997), Iran (Lorestan) ( GHAHARI et al. 2015, this paper).
