Description. Female ( Fig. 3 View FIGURE 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 View FIGURE 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 View FIGURE 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 View FIGURE 1 D) shiny, unsculptured, crossed by slight anterior furrow and with disc humped; pronotal tubercle not reaching tegula ( Fig. 1 View FIGURE 1 F). Scutum ( Fig. 1 View FIGURE 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 View FIGURE 1 C) reticulate rugose, with two short incomplete longitudinal keels on posterior surface. Fore wing ( Fig. 1 View FIGURE 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 View FIGURE 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 View FIGURE 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:
