Redescription.

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.

Differential diagnosis.

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.

Etymology.

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.
