Description – Head light brown to reddish brown with sparce short and thin golden setae; 6 macrochetes: 2 between the eye and the base of the clypeus, 2 just behind the ocelli, 2 near the apex of the clypeus. Eyes round not prominent laterally, without setae.

Antennae ( Fig. 5), first joint short, cylindrical, yellowish to brown; 2nd the longest, regularly enlarged from base to apex, yellowish with embrowned apex or basal half brown and apical half blackish; 3rd fusiform, yellowish, apex embrowned or not, basal third brown and apical two third blackish; 4th elliptic, always blackish. First antennal joint with short and thin white setae at the apex, other joints with golden or light brown setae, some of them recumbent and others semi erect; on 4th joint some setae nearly perpendicular to joint axis. Antennae hardly shorter than the head, pronotum and scutellum together.

Pronotum blackish, anterior collar very thinly transversally striate; anterior calli smooth and shiny; disc – just behind the calli – strongly concave, with thin golden setae di- rected backwards. Anterior angles nearly absent, little marked. Lateral margins slightly con- cave at calli level; humeral angles obtuse or rounded; posterior margin regularly concave.

Scutellum triangular blackish with thin golden setae (like those on the pronotum), basal half regularly rounded, apical half flat ( Fig. 3).

Hemelytron ( Fig. 3), clavus brown more or less dark. Endocorium light brown at the extreme apex, regularly embrowned from apex to base, cuneal region dark brown or black- ish; exocorium brown, darkened laterally (reddish or brown) at base or base completely dark brown. Clavus and apex of endocorium until the inner angle of the corium with long strong white and hooked setae ( Fig. 4); the rest of the mesocorium (including the cuneus) with short black and erected setae; margin of the base of the exocorium and cuneus with thin light brown setae. Cuneus, base of the corium and basal half of the exocorium very shining; the rest less shining and seeming dull due to the pilosity (strong white setae).

Membrane milky white, smoked posteriorly and also very thinly along the base of the corium ( Fig. 3).

Ventral side of the head brown to reddish; rostrum dark brown to blackish.

Pectus dark brown, reddish brown or light brown (in this case propectus orange). Middle of the pectus with thin, recumbent white or golden setae. Mesopleura regularly and thinly striate with some thin setae. Evaporatorium subrectangular ( Fig. 10), external angles round; transverse ostiolar peritreme abruptly curved at the end and directed up- ward continuing in a suture line which does not reach the anterior margin of the meta- pleura. Coxae and femora yellowish-orange, light brown or reddish; tibiae and tarsi yel- lowish or pale orange. Setae of femora very thin, semi erect, golden; those on tibiae golden, stronger and more numerous than those on femora, semi erect.

Venter black, reddish or brown (more or less dark). Anterior margin of sternites with stiff white pegs, some on lateral sides shorter; 2nd sternite ( Fig. 6) regularly and deeply concave sub medially, internal mid line in a rounded hip; lateral cuticular fold strong.

Paramere lengthily triangular ( Figs 7–9), external margin straight or hardly bent (de- pending upon orientation), apex round or acute, briefly curved.

Differential diagnosis – The paramere of Anthocoris golestanicus sp. n. only matches well with those of the japonicus -group: Anthocoris japonicus Poppius, 1909 , A. takahashii Hiura, 1959 and A. ussuriensis Lindberg, 1927 ( BU & ZHENG 2001). In these three species the paramere is more ( ussuriensis and takahashii ) or less ( japonicus ) curved whereas in A. golestanicus sp. n. it is nearly straight or gently bent ( Figs 7 & 8). Anthocoris golestanicus sp. n. differs from other members of the japonicus -group by its antennae hardly shorter than head, pronotum and scutellum together (much shorter in the three other spe- cies) and by the long strong white and hooked setae on the clavus and apex of the endocorium. Anthocoris golestanicus sp. n. is the smallest species of the group: 2.43–2.61 vs 3.4–4.0 mm.

0.06 mm), 10 = evaporatorium (scale 0.1 mm)

Etymology – The specific name is after the province (Golestan) where the type mate- rial have been collected.

Distribution – All the samples have been collected from Iran, Golestan province, Dasht e-Mirzabaylu, on 8th June of 2011 by H. Ghahari by aspirator and batting Rubus hyrcanus (Linnaeus) (Rosaceae) .

Plant association – Rubus hyrcanus (Linnaeus) (Rosaceae)

Biology – Predator of Aphis idaei van der Goot, 1912 ( Hemiptera : Aphidi- dae) and Aleurocanthus zizyphi Priesner & Hosny, 1934 ( Hemiptera : Aleyrodi- dae). A. zizyphi was recorded from Golestan province on Rubus hyrcanus by GHAHARI et al. (2007).
