DIAGNOSIS: Recognized by the scalelike setae covering entire dorsum, pleurites, and abdomen (as in figs. 22 A-C, E, 23 A, D), dark brown to black body except for narrow yellowish spot near inner margin of each eye, evaporatorium and claval suture in male yellowish (fig. 1), aedeagus with long spicule somewhat curved basally and apically and short spicule comma-shaped, less than half as long as long spicule (fig. 7), medial sclerites of dorsal labiate plate twisted basally, distinctly twin-coned apically, comparatively small, of same length as and distinctly narrower than sclerotized rings (fig. 14). Males not easily confused with any other species. Females similar to O. funestus   , but that species often can be distinguished by the pale brown or yellowish forecoxa and yellowish or brown femora with darker dots. Not separable from dark-colored females of O. funestus   , because of the great similarity in the genitalic structure.

REDESCRIPTION: Male: Macropterous; length 4.5–5.1. COLORATION (fig. 1): Body uniformly dark brown to black except for dirty yellow spot near inner margin of each eye, evaporatorium yellow, and typically with narrow yellow longitudinal stripe on each outer part of clavus and inner half of corium, membrane uniformly pale brown. SURFACE AND VESTITURE: Head and hemelytra smooth, pronotum and scutellum somewhat rugose. Dorsum, pleurites, and abdomen clothed with adpressed scalelike setae (as in figs. 22 A-C, E, 23 A, D); all appendages and abdomen with dark semiadpressed simple setae, especially long, dense, and semierect on antennal segments; entire dorsum, forecoxa, fore margin, and apex of femur with contrastingly long, erect bristlelike setae, somewhat shorter than diameter of eye, especially long on anterior margin of pronotum, head, and bases of hemelytra; antennal segment I with two mesial spines. STRUCTURE AND MEA- SUREMENTS: Body 2.9–3.4× as long as width of pronotum. Head: Shape of head and eye similar to those of O. bivittatus   (as in figs. 20 B, 21 A, G); head 1.2–1.3× as wide as high; vertex 2.0–2.3× as wide as eye; eye located at a short distance from anterior pronotal margin; antennal fossa located close to inferior margin of eye; antennal segment I longer than diameter of eye; antennal segment II cylindrical, sometimes somewhat incrassate apically; 0.9–1.1× as long as basal width of pronotum, 1.1–1.3× as long as width of head; labium reaching middle coxa. Thorax: Pronotum 1.9–2.4× as wide as long and 1.2–1.3× as wide as head, with straight or slightly concave posterior margin, lateral margins of pronotum not carinate, calli slightly raised; hind femora relatively narrow, approximately 1.5× as wide as middle femora. GENITALIA: Aedeagus (fig. 7) with two spicules; long spicule longer than dorsal wall of theca, somewhat curved basally and apically, short spicule comma-shaped, distinctly shorter than dorsal wall of theca, less than half as long as long spicule; parameres as in fig. 14.

Female: Brachypterous, length 3.6–4.6. COLORATION: Similar to male; hemelytra dark brown to black, often with dirty yellow longitudinal marking at base of claval suture. SURFACE AND VESTITURE: As in male. STRUCTURE AND MESUREMENTS: Body 2.1–3.0× as long as width of pronotum. Head: 1.2–1.3× as wide as high; vertex 2.3–2.7× as wide as eye; antennal segment II 0.8–1.1× as long as basal width of pronotum, 0.9–1.2× as long as width of head. Thorax: Pronotum 2.0–2.4× as wide as long, 1.0–1.3× as wide as head; length of hemelytra ranging from reaching middle of abdominal segment VII to covering entire abdomen, typically covering abdominal segment VII; cuneus weakly delimited, claval commissure as long as inner claval margin; posterior and lateral margins of hemelytra rounded. GENITALIA: Sclerotized rings comparatively large, elongated; medial sclerites twisted basally, distinctly twin-coned apically, comparatively small, of same length and distinctly narrower than sclerotized ring (fig. 14); posterior wall of bursa copulatrix with trapeziform sclerite uniformly sclerotized, incision on the anterior margin narrow and not reaching middle of sclerite, anterior angles of this sclerite somewhat dentate, posterior margin without sclerites (as in fig. 18, bivittatus   ); vulva with curved sclerites forming a circle (as in fig. 19, O. vittipennis   ).

DISTRIBUTION: In the Palearctic region the distribution of this species spans Western and Central Europe. It has not been recorded from Russia except Kaliningrad Province. Introduced to North America ( Wheeler, Henry and Mason, 1983; Henry and Kelton, 1986). New records for Tunisia.

HOSTS AND NATURAL HISTORY: Kullenberg (1944), Southwood and Leston (1959), and Wheeler (1985) provided information on seasonal history and host plants of O. coriaceus   . The species is typically found on dry, open, sandy areas where it feeds on various composites. Wheeler (1985) also sampled the species from herb and flower gardens. According to Kullenberg (1944), O. coriaceus   usually attacks stems and leaves, especially the veins, of its hosts; adults have been observed to feed on inflorescence of grasses. Eggs are inserted in host stems. Overwintering occurs in the egg stage. In Sweden and the British Isles ( Kullenberg, 1944, Southwood and Leston, 1959) adults begin to appear in mid- to late June. In North America ( Wheeler, 1985) eggs begin to hatch by late April, adults appear in the end of May and are present until late June. Wheeler (1985) also provided detailed descriptions of all instars.

O. coriaceus   seems to be closely associated with Asteraceae   . According to Kullenberg (1944) Achillea millefolium   L. and Tanacetum vulgare   L. ( Asteraceae   ) are favorable hosts in Sweden. In Europe, the species also reported from the following species of Asteraceae   : Carduus spp.   , Centaurea scabiosa   L. ( Reuter, 1891), Tanacetum sp.   ( Saunders, 1892), Tanacetum vulgare   L. ( Franz and Wagner, 1961), Achillea sp.   , Centaurea sp.   ( Wagner, 1974); Leucanthemum   vulgare Lam.   (as Chrysanthemum leucanthemum   L.) ( Woodroffe, 1959). However, the species was also sampled from Rubiaceae   : Galium sp.   ( Woodroffe, 1959) and Galium verum   L. ( Franz and Wagner, 1961); Lamiaceae   : Galeopsis bifida Boenn. ( Franz and Wagner, 1961)   ; Fabaceae   : Sarothamnus scoparius   (L.) (as Spartium scoparium   L.) ( Reuter, 1891); Fagaceae   : ( Ehanno 1960) and Quercus occidentalis J. Gay   (as Quercus pedunculata Ehrh.   ) ( Ehanno, 1965).

Wheeler (1985) noted that in North America most common hosts in ruderal sites were Cichorium intybus   L., Chrysanthemum leucanthemum   L., Centaurea maculosa Lam.   , and Tanacetum vulgare   L. ( Asteraceae   ). He also listed all host plants of O. coriaceus   in eastern United States belonging to three tribes of Asteraceae   - Anthemidiae, Cynareae   , and Cichorium   , - and chiefly represented by species of Achillea   , Artemisia   , and Chrysanthemum   . In addition to species noted by Wheeler (1985), O. coriaceus   was reported from Solidago sp.   ( Asteraceae   ) by Messina, (1978) and from Potentilla erecta   (L.) ( Rosaceae   ) by Wheeler et al. (1983).

Some specimens from the collection of ZISP were collected from Achillea millefolium   L. ( Asteraceae   ) by an unknown collector and from Achillea sp.   ( Asteraceae   ) by Seidenstücker. Also a single specimen was collected from Cerasus   vulgaris Mill. (as Prunus cerasus   L.) ( Rosaceae   ) by A. Matocq.

DISCUSSION: Males and females with uniformly dark brown to black appendages and hemelytra collected from Kyrgyzstan (in the collection of ZISP) share the genitalic structure typical of O. coriaceus   and O. funestus   . Although these two species can hardly be separated from each other by the genitalic structure without considerable experience, they have minor distinctions in the shape of the short spicule of the aedeagus (fig. 7). However, the shape of the short spicule in specimens from Kyrgyzstan does not allow for their placement in either of these two species with certainty. These males and females are similar to O. coriaceus   in the general appearance and size, but differ in having uniformly dark brown to black hemelytra. Orthocephalus funestus   usually has pale brown or yellowish femora with minute spots and pale brown coxa. Specimens of O. funestus   with uniformly dark brown to black legs and antennae were noted only from Japan and Kuril Islands; they are similar to specimens from Kyrgyzstan in coloration but differ from them in all other respects. Because of the general habitus and size, these specimens are treated as O. coriaceus   . More material from Central Asia is needed to clarify this issue.
