Description. Female (Fig. 3). Fully winged; body length 4.1–4.2 mm (holotype 4.1 mm). Antenna clavate, ratios of antennal segments 9:4:24:13:11:10:7:7:6:6. Rhinaria lacking on antennal segments. Head (Figs 1 A–B, D) dull, slightly granulated and sculptured by many subparallel longitudinal striae; frontal line (Fig. A) incomplete, present in posterior half of face; occiput and temple shiny, unsculptured; occipital carina incomplete, present only behind ocellar triangle (Fig. 1 D); posterior ocelli touching occipital carina; POL=4; OL=4; OOL=8; TL=1; greatest breadth of posterior ocelli shorter than OL (3:4); greatest breadth of anterior ocellus about as long as OL. Pronotum (Fig. 1 D) shiny, unsculptured, crossed by slight anterior furrow and with disc humped; pronotal tubercle not reaching tegula (Fig. 1 F). Scutum (Fig. 1 C) dull, hairy, strongly reticulate rugose. Notauli absent. Scutellum reticulate rugose, with areolae much smaller than those of scutum and metanotum. Metanotum reticulate rugose. Propodeum (Fig. 1 C) reticulate rugose, with two short incomplete longitudinal keels on posterior surface. Fore wing (Fig. 1 H) with two dark transverse bands on basal cells and beneath pterostigma; distal part of stigmal vein about as long as proximal part. Ratios of protarsomeres 14:3:7:12:23. Enlarged claw (Figs. 1 G, 2B) not spatulate, without teeth, with one row of 6–7 proximal and medial lamellae (6 in holotype) and group of 4–6 distal lamellae (4 in holotype). Protarsomere 5 (Fig. 2 B) with one short row of 6 lamellae; distal apex with at least 19 lamellae. Rudimentary claw longer than arolium. Tibial spurs 1/1/1. Coloration. Head ferruginous; antenna ferruginous, except segments 7–10 darkened; prothorax ferruginous; rest of mesosoma black; petiole black; metasoma brown, except first segment testaceous; legs testaceous, except inner side of metafemur club, distal half of metatibia and part of metatarsus brown.
Distribution. Iran.
Hosts. Unknown.
Etymology. The species is named after Tamarix, the plant on which it was collected.
Remarks. The female of Dryinus tamaricicola sp. nov. has no rhinaria on antennal segments and it seems a unique case among all known Dryinus species. The new species belongs to Dryinus group 3, according to the classification of Xu et al. (2013), Olmi & Virla (2014) and Olmi & Xu (2015). Dryinus tamaricicola sp. nov. is close to D. balearicus Olmi, 1987; D. gharaeii Olmi, 2005; D. ibericus (Olmi, 1990); D. sanderi Olmi, 1984 and D. tigarae Olmi, 2008. Following the description of D. tamaricicola sp. nov., the final part (couplets 9–15) of the key to the females of Western Palaearctic species of Dryinus (Olmi 1999), partly modified by Olmi (2005) and valid also for Eastern Palaearctic species should be replaced by the following couplets:

Enlarged claw with one row of proximal and medial lamellae (Figs 167, 169, 170 in Olmi 1999; Fig. 2 B)............... 10 - Enlarged claw with one or more small lamellae situated near distal apex (Figs 159, 160, 162, 165, 293 in Olmi 1999)..... 1 5 10.

& Xu 2015); protarsomere 5 with one row of very long lamellae, in addition to further rows of shorter lamellae (Fig. 2 A, fig. 2
in Olmi 2008; plate 26E in Olmi & Xu 2015); occipital carina incomplete, not present on temple, laterally reaching eyes; rudi-
mentary claw longer than arolium (Fig. 2 A, fig. 2 in Olmi 2008; plate 26E in Olmi & Xu 2015)..................... 12 - Enlarged claw not spatulate, with two subapical teeth and one shorter row of lamellae (Figs. 167, 169, 170 in Olmi 1999); pro-
tarsomere 5 without row of very long lamellae, with rows of lamellae approximately same length (Figs. 167, 169, 170 in Olmi
1999); occipital carina complete, laterally not reaching eyes; rudimentary claw shorter than arolium (Figs. 167, 169, 170 in
Olmi 1999)........................................................................................ 13 12. Head sculptured by irregular longitudinal keels and large punctures; head black, except mandible testaceous; mesosoma black
