Figures (2A–F, 3A–F, 4A, B)
Dendrosoter ferrugineus Marshall, 1888: 247, ♀.
Material examined. 13♀, 2♂.
Diagnosis. Female: Body length: 2.5–3.8 mm.
Body generally dark ferruginous, with some parts lighter (Figures 2A, C, D, 3A, B, 4A); antenna with scape, pedicel, F1 and basal part of F2 light red, rest of antenna dark brown (Figure 2E); legs pale brown to yellow, with dark brown last tarsomere (Figure 3C, D); Forewing with pterostigma dark brown, yellow basally and apically (Figure 3E); head dorsally (Figure 2D), vertex, and face finely transversely rugose (Figure 2C); gena transversely rugose above and smooth behind; ocellar triangle with base 1.3× as long as lateral sides; antenna 33-segmented, scape distinctly shorter than F1, F1 5.7× as long as its width, about as long as F2 (Figure 2E); mesoscutum coarsely rugose, with deep, crenulate notauli that end in a rugose area before apex of mesoscutum (Figure 3A); Forewing with vein r-m present but membranous (Figure 3E); mid and hind tibiae each with a row of separate thick black spines along their outer surfaces (Figure 3C, D); hind tarsus 1.26× as long as hind tibia; metasomal T1, T2 and base of T3 coarsely longitudinally rugose, rest of tergites smooth and shiny (Figure 4A); ovipositor sheath slightly longer than metasomal length, 0.6× as long as forewing length, pointed apically and slightly widened preapically, rest slender and setose throughout (Figure 4A).
Male. Body length: 2.56–2.68 mm.
Resembles female but differs in having body distinctly slender (Figures 2B, 4B); one of the two reared specimens has the same colour as the female, while the other is brighter in colour; antenna 25-segmented, with scape, pedicel, F1–5 red, rest of flagellum dark brown (Figure 2F), in addition to sexual differences.
Distribution. Armenia, Azerbaijan, Bosnia-Herzegovina, France, Greece, Iran, Israel-Palestine, Italy, Russia, Saudi Arabia, Spain, Turkey, United Arab Emirates, former Yugoslavia (Ghahari et al. 2022), Syria (new record).
Host records. Scobicia chevrieri (Villa and Villa) (Bostrichidae) (Belokobylskij and Tobias 1986; Papp 1991), Sinoxylon sexdentatum (Olivier) (Bostrichidae) (Lichstenstein and Picard 1918; Belokobylskij and Tobias 1986; Papp 1991), Chaetoptelius vestitus (Mulsant and Rey) (Curculionidae) on Pistacia vera L. (Anacardiaceae) (Russo 1938), and Phloeotribus scarabaeoides (Bernard) (Curculionidae) (Russo 1938; Belokobylskij and Tobias 1986; Papp 1991; Hedqvist 1998). In the present study, reared from A. bimaculatus (Olivier) (Bostrichidae) on P. granatum L.
Comments. Characters of the Syrian specimen agree with Tobias et al.’s key (1995, p. 62, couplet 6), but it differs in having vertex and temples with fine transverse rugosity (Figure 2C, D) (with very dense granulose sculpture in Tobias et al. 1995); ocellar triangle base 1.3× as long as lateral sides (Figure 2D) (1.5× in Tobias et al. 1995). It also resembles the Saudi Arabian specimen (Edmardash et al. 2020), but differs in having ovipositor sheath slightly longer than metasomal length (Figure 4A) (as long as metsomal length in the Saudi specimen, see Edmardash et al. 2020, p. 50, fig. 5B); antennal F1 5.7× as long as its apical width (Figure 2E) (5.0× in the Saudi specimen); body length 2.5–3.8 mm (4.8 mm in the Saudi specimen); head reddish (Figure 2A, C, D), mesosoma dark ferruginous with some black (Figure 3A, B) (head and mesosoma dark brown in Saudi specimen); wing hyaline with slight darkness behind pterostigma (Figure 3E) (entirely hyaline in Saudi specimen, see Edmardash et al. 2020, p. 49, fig. 4A).
