PARATYPES: 3♂, one male the same data as holotype and 2 males Sarvabad ; Daraki (35˚19´N 46˚09´E, 1705m) , 04.VII.2017. The holotype and paratypes are deposited in the insect collection of the Natural History Museum of the University of Guilan, Rasht, Iran .

Diagnosis. The new species is recognized by the following combination of characters: body length 7.62–8.11 mm, eyes red; whole body yellowish stramineous; ocular index 1.83–2.0, antennal segments I 1.35–1.59× and II 2.95–3.20× longer than head width, antennal segment II 1.81–1.88× longer than posterior width of pronotum. Pronotum 1.90–1.97× wider than long. Left and right side of pygophore with blunt tubercle. Male genitalia as Fig. 2 . Spiculum with 17 teeth.

Description. Male. Colouration. Whole body yellowish stramineous ( Fig. 1 ), head with faint stramineous arcs on vertex and frons, eyes red; labium generally stramineous, fourth segment brownish; antennal segments yellowish stramineous, antennal segment I mottled with faint stramineous spots. Collar mostly faint stramineous, pronotum with three faint longitudinal stramineous stripes, one medial and two sub–lateral, mesoscutum and scutellum faint stramineous. Membrane of hemelytra hyaline. Legs generally concolorous with body; femora generally mottled with faint stramineous spots. Lateral and ventral side of body yellowish stramineous.

Structure, vestiture and texture. Macropterous. Body elongate, head densely covered with semierect long whitish setae, eyes glabrous, attached to collar; gena barely visible in lateral view, antennal segment I with a few long bristle like setae and densely covered with whitish short setae, II–IV densely covered with whitish setae; labium surpassing metacoxae. Pronotum, scutellum and hemelytra covered by decumbent, whitish and golden to brownish, hair–like setae, collar distinct, calli obsolete, posterior margin of pronotum smooth, mesoscutum exposed, cell membrane distinct, ventral side of body and legs with whitish setae.

Male genitalia: pygophore covered with long hair–like setae, left and right side with blunt tubercle, left paramere slightly bent, apophysis with spoon–shape beak, sensory lobe tumid ( Figs 2 A–E ), right paramere simple ( Figs 2 F–H ), apophysis weakly arcuate, endosoma as in Fig. 2I . Secondary gonopore large, rectangle shape, spiculum with 17 teeth.

Measurements. Body length 7.62–8.11, width 2.06–2.31; lengths of antennal segments: I:1.49–1.69, II: 3.0– 3.29, III: 2.21–2.24, IV: 1.13–1.33; head width across the eyes (in dorsal view) 1.0–1.1; interocular width 0.48– 0.53, width of eye 0.25–0.27; ocular index 1.83–2.0; length of head (in lateral view) 0.62–0.71, height of head in lateral view 0.80–0.91, width of pronotum on posterior margin 1.67–1.78; length of pronotum in the middle (without collar) 0.84–0.91; pronotum 1.90–1.97× wider than long; width of anterior part of pronotum (collar) 0.68– 0.75; length of collar 0.11–0.33; antennal segment I 1.35–1.59× head width; antennal segment II 2.95–3.20× head width; 1.81–1.88× posterior width of pronotum; length of scutellum 0.73–0.80; width of scutellum at anterior margin 0.80–0.89.

Female. Unknown

Differential diagnosis. The new species belongs to the subgenus Eckerleinius Wagner, 1968. It is close to Ph. (E.) niveatus Horvath, 1891 ( Fig. 5 ) and Ph. (E.) elburzanus Linnavuori, 2000 ( Fig. 6 ), recognized by the presence of two tubercles on the left and right sides of genital chamber (without tubercles in two other species), size of second antennal segment / head width (2.3–2.7 in Ph. niveatus , 2.1–2.2 in Ph. elburzanus ) and teeth of spiculum (24 in Ph. niveatus , 23 in Ph. elburzanu s) (see Linnavuori 2000). Vestiture in P. elburzanus is relatively short, white and recumbent and P. niveatus has some semi–erect, white setae on pronotum and cuneus. New species has a unicolorous dorsal surface, while numerous Eckerleinius species have complex dorsal – pronotal and/or hemelytral color pattern. P. hawramanicum sp. nov. can be separated from all Middle-East Eckerleinus species by the key hereafter.

Etymology. The species is named after Hawrāmān (also Húrāmān– a mountainous region located within the provinces of Kurdistan and Kermanshah in western Iran and in north–eastern Iraq within Iraq's Kurdistan region) from where the type material was collected.

Collection circumstances. Collected by light trap located in a hilly slope covered by Pistacia atlantica , Acer monspessulanum, Prunus scoparia and Lonicera sp. ( Fig. 4 )

Distribution. Iran (Kurdistan province).
