Structure. Head porrect, robust, about as long as wide across eyes, strongly gibbose dorsally, anterior portion of head (anteriad of antenniferous tubercles) long (Fig. 2). Clypeus anteriorly surpassing mandibular plates. Antenniferous tubercles large, apically produced into long, inward-curved projection embracing base of antennal segment I. Compound eyes small, globular, protruding from head outline by most of their width (Fig. 2). Ocelli situated on small tubercles slightly posteriad of posterior margin of compound eyes, directed dorsolaterad; each ocellus closer to eye than to each other. Antennal segments ordered from longest to shortest: II > IV > III ≥ I. Antennal segment I robust, obovate, narrowing in basal one quarter of its length, slightly curved towards base, its apex surpassing apex of clypeus anteriorly; antennal segments II–IV much more slender, II and III almost cylindrical, slightly widening towards apex, IV spindle-shaped, with constricted base (Fig. 2). Bucculae short, covering approximately anterior half of labial segment I, surpassing labial segment I ventrally, ventral margin rounded, anteriorly reaching apex of clypeus (Fig. 4). Labial segments ordered from longest to shortest: I > II > IV > III; apex of segment I not reaching posterior margin of head, apex of segment II reaching anterior margin of procoxae, and apex of segment IV reaching anterior margin of mesocoxae (Figs 3, 4).

Pronotum trapezoid, anterior margin slightly concave, lateral and posterior margin nearly straight (Fig. 2). Pronotum highest at line connecting humeral angles, sloping anteriorly towards head (Fig. 4). Pronotal disk flat, slightly sloping towards lateral and posterior margin. Anterior margin of pronotum raised, forming sharp collar (most prominent laterally) (Figs 2, 3), constricted posteriorly by deep transverse groove continuing to propleura; anterolateral angles of pronotum such as in Ceraleptus not developed. Lateral margins of pronotum and humeral angles rounded, unarmed, not protruding (Fig. 2).

Scutellum triangular, slightly wider than long, flat, only anterolateral angles with small depressions, apex acutangulate (Fig. 2).

Thoracic venter. Mesosternum depressed between mesocoxae. Metasternum anteriorly convex, narrowing posteriad, metacoxae situated close to each other (Fig. 3). Metapleuron posterolaterally rounded, not protruding (Fig. 3). Ostiole of metathora- cic scent glands shifted somewhat laterad, situated between meso- and metacetabulum, laterally accompanied with a short peritreme; vestibular scar well visible; evaporatorium very small, narrowly surrounding vestibular scar, ostiole, and peritreme.

Legs. All femora oval in cross-section. Profemur widest in midlength, mesofemur approximately in its apical third (Fig. 3), both unarmed. Metafemur clavate, widest subapically (Fig. 3), its ventral surface with two parallel rows of more than ten spines and small denticles getting bigger from base to apex, two to four of the spines being large, the spines in rows being situated in nearly equal distances; surface between both rows flat, smooth. Tibiae somewhat flattened laterally, slightly widening from base to apex, unarmed. Tarsomeres ordered from longest to shortest: I > III > II, tarsomere I being slightly longer than II and III combined (Fig. 3).

Wings. Corium widest approximately at midlength, narrowing both anteriad and posteriad, costal margin of corium therefore slightly convex medially; posterolateral angle of corium acutangulate (Fig. 2). Membrane apically rounded, reaching apex of abdomen (♂; Fig. 2) or slightly shorter (♀). Hind wings developed.

Abdomen widest slightly behind its midlength (Fig. 3). Corium exposed, directed dorsolaterad, its outer margin smooth, posterolateral angles of laterotergites not protruding (Fig. 3), except for obtusangulate posterolateral angles of laterotergite VII in females. Abdominal venter regularly convex.

Male genitalia. Pygophore (Figs 5–9) black, lateral angles slightly brownish, insinuated anterolaterally, posterolateral angles distinctly produced, lobe-like, surrounding parameres laterally; infolding of ventral rim large, with a pair of depressions harbouring basal portion of parameres (Fig. 7). Paramere sockets not visible in dorsal view, covered by posterolateral angles of pygophore (Figs 6–7). Paramere (Figs 10–13) clavate in posterior (outer) and anterior (inner) view, slightly S-shaped in lateral view; posterior surface (Fig. 13) of head of paramere flattened, pale brown, bearing sparse and stout setae arising from large punctures; rest of paramere body blackish; inner surface (Fig. 11) produced into two ridges holding acute angle, distal ridge higher, apically rounded, proximal one lower and angulate; surface between the ridges and between proximal ridge and base of the paramere concave, rest of anterior surface convex. Phallus (Figs 14–16) with sclerotized vesica with two coils and a single pair of long endophallic reservoir outgrowths.

Urartucoris differs from all Palaearctic Pseudophloeini in very long antennal segment II, sharp and well delimited pronotal collar, and presence of two nearly identical rows of denticles and spines on metafemora, the spines in the rows being situated in nearly equal distances. It resembles the genus Ceraleptus (especially Ceraleptus gracilicornis (Herrich-Schaeffer, 1835)) in the close position of the metacoxae but it differs from it, besides the above mentioned generic characters, in the robust antennae and the body being covered by stiff spinules (Putshkov 1979). See also the Key below. Also Dolling (1986) suggested close relationship between Urartucoris, Ceraleptus, and Microtelocerus, but without listing a single shared character.

Originally, etymology of the name was not specified. The name consists of the name Urartu, which was an ancient Armenian kingdom (ca. 860–585 B.C.) spread out between Asia Minor, Caucasus and Mesopotamia, with center around the Van Lake (today in eastern Turkey), and the ending -coris, used for true bug. The name is masculine.

Colouration (Figs 2–5).Body dorsally dark brown, except three ochraceous stripes dorsally on head, one in midline, running from base of head towards base of clypeus, and two lateral ones, running from base of head along inner margin of eye towards base of antenniferous tubercle; elongate ivory spot on apex of scutellum; and rather irregular whitish spots posterolaterally on laterotergites. Membrane brownish, with small round pale spots; veins dark brown. Antennae and labium black. Head ventrally brown. Thorax ventrally dark brown, pleura to various extent covered with smaller to larger, irregular, sometimes confluent ochraceous spots, especially on metapleuron. Profemora, metatibiae and metatarsi blackish brown. Meso- and metafemora blackish brown with irregular ochraceous spots, especially on dorsal surface. Pro- and mesotibiae ochraceous, basally and apically infuscated with dark brown, pro- and mesotarsi dark brown. Abdomen ventrally pale with nearly continuous wide blackish stripes laterally and at mid-distance between lateral margin and midline, sternites III–VII with narrow, black, nearly continuous to interrupted stripe along midline.

Measurements. Males (mm; n = 8): Body length 9.4–10.3; head: length 1.7–1.8, width across eyes 1.7–1.8, interocular width 1.0–1.3; pronotum: length 1.9–2.1, width across pronotal collar 1.6–1.8, width across humeral angles 2.9–3.3; scutellum: length 1.1–1.3, width 1.4–1.6; abdomen: maximum width (slightly behind its midlength) 4.0–4.2; length of antennal segments: I – 0.9–1.1, II – 1.2–1.5, III – 0.9–1.1, IV – 1.0–1.2; profemur: length 1.8–2.2; protibia: length 1.7–2.0; mesofemur: length 2.1–2.5; mesotibia: length 2.0–2.3; metafemur: length 2.7–3.6; metatibia: length 3.0–3.5.

Females (mm; n = 4): Body length 10.5–11.0; head: length 1.7–1.9, width across eyes 1.8–2.0, interocular width 1.2–1.25; pronotum: length 2.0–2.1, width across pronotal collar 1.7–1.9, width across humeral angles 3.1–3.4; scutellum: length 1.2–1.4, width 1.5–1.7; abdomen: maximum width (slightly behind its midlength) 4.2–4.6; length of antennal segments: I – 0.9–1.1, II – 1.3–1.4, III – 1.1 (n = 1), IV – 1.2 (n = 1); profemur: length 2.0–2.3; protibia: length 1.9–2.2; mesofemur: length 2.3–2.6; mesotibia: length 2.1–2.3; metafemur: length 3.1–3.8; metatibia: length 3.0–3.4.

Pilosity and vestiture. Body dorsum (except membrane), antennae and legs covered with long, stiff, semi-erect to erect, brown to black spinules, arising from apices of small tubercles (best visible in lateral view); tubercles largest on vertex and anterior portion of pronotum, those on posterior portion of pronotum, scutellum, and coriaceous part of hemelytra smaller. Spinules on tibiae nearly as long as half of diameter of tibia, those on femora nearly as long as the large spinules on pronotum. Body venter with double pilosity: Long, stiff, semi-erect to erect, dark spinules as those on body dorsum, but distinctly sparser, arising from smaller tubercles, short on pleura and ventral surface of head. Besides the dark spinules, body venter covered with intermingled, sparse, adpressed, whitish setae, slightly shorter than the spinules. Antennal segment IV covered with very short and fine adpressed pubescence among the sparse, long black spinulae. Besides the tubercles body covered with irregularly scattered, deep and dark punctures, largest on clavus.

The male resembles the female in most of the characters except for slightly smaller body (9.4–10.3 mm) than in females (10.5–11.2 mm), membrane reaching apex of abdomen (slightly shorter in females) and shape of last abdominal segments. We found also some differences in colouration, but this may represent rather intraspecific variability than sexual dimorphism: Peritreme yellowish, only slightly infuscated on its lateral edge (♂); peritreme black (♀). Abdominal sternites III–VII with narrow, black, nearly continuous stripe along midline (♂); sternite III medially with large blackish spot, the black longitudinal stripe in ventral midline being interrupted, ventrites IV–VI medially with only smaller black spots posteriorly (♀). The extent of ochraceous colouration on thoracic pleura is certainly variable among specimens.

The Turkish specimens fit well the original description except for a few details. The mesofemora of the Turkish specimens are unarmed, while Putshkov (1979) mentioned mesofemora with two small spines. There are also slight differences in colouration. According to Putshkov (1979), the Nakhchivan specimens differed, e.g., in antennae dark brown with antennal segment I black; anterior portion of pronotum paler than its posterior portion, darkened near lateral margins and along midline; meso- and metafemora pale, apically darkened, especially dorsally; and abdomen ventrally pale with isolated dark spots, forming two interrupted stripes in lateral midlines (halfway between connexivum and ventral midline of abdomen). The Turkish females are either slightly smaller or approximately as large as the Nakhchivan specimens.

Originally, etymology of the name was not specified. Most probably, the species was dedicated to Valeriy Mikhaylovich Ermolenko (1920–2006), an Ukrainian expert in Hymenoptera: Symphyta and collector of the holotype.

Adults were collected from mid April to end of July and in mid September (Putshkov 1979, this paper).

All the specimens of Urartucoris ermolenkoi (all adults) were collected between April and September 2008 using pitfall traps; collecting by other methods (yellow traps) yielded no specimens of this apparently epigeic species. The species was collected at five different semi-natural collecting sites in higher altitudes (1420–1621 m a.s.l.), ranging from sparse forest to mountain grassland (Figs 18–20).

• A Xerophilic natural plants with a reforested area with pine trees (Pinus sp.) and cedars (Cedrus sp.) planted between 1959–1969 (Şahbudak & Cengiz 2007); about 4.8 % of the plants that were recorded from this site were endemic to Turkish flora. Altitude 1472 m (Fig. 18).
• B Main entrance to the GNP, this is an area close to the lake, with areas reforested with Robinia pseudoacacia planted between 1960–1965. Some natural plants like Crataegus orientalis, Cotoneaster nummularia, Pistacia terebinthus and other are also represented in this site which has high human activity (picnic area). Altitude 1420 m.
• C Mesophilous area with plantation of 50–60 years old Populus spp. trees, accompanied by Crataegus orientalis, Cotoneaster nummularia, Pistacia terebinthus, Rosa canina, Pyrus, Juglans and Malus spp. Altitude 1485 m.
• D Dry xerophilic sandy place with Robinia pseudoacacia plantations and natural shrubland with different dominant Astragalus spp., many of them endemic. Altitude 1443 m (Fig. 19).
• E Highland site, reforested in 1989 with Cedrus sp. and Robinia pseudoacacia. Altitude 1621 m (Fig. 20).
