description: Reuteria winkelmanni Günther & Strauss 2018
(Fig. 3)
Material examined: Antalya: Saklıkent, 26. VII. 1985, 1 female (on Quercus sp.); Mersin: Silifke, Uzuncaburç, 05. VII. 1986, 6 males, 2 females; Toroslar, Arslanköy, 08. VII. 1986, 1 female (on Quercus sp.); Çamlıyayla, 10. VII. 1986, 3 males, 3 females, B. Çerçi det. (LEMT).
Differential diagnosis: Combination of following characters differentiates this species from its congeners: Background coloration whitish, with green staining, first antennal segment with two black longitudinal stripes on opposite surfaces, second antennal segment with a dark ring basally, hemelytra slightly enlarged towards the apex of the corium, right paramere with a strongly inward bent apical process and fan-shaped apically serrated lateral process (Fig. 3 D-E), vesica with four sclerotized processes as in Fig. 3 F–G.
Redescription of male:
Coloration: Ground coloration white, with green maculation. Head pale, immaculate. Antennae pale yellow colored, first antennal segment with two longitudinal black stripes on opposite surfaces, second antennal segment with narrow dark ring above very narrow pale ring basally, rest of antennae immaculate. Pronotum pale with traces of green maculation on the posterior lobe. Scutellum pale, mostly immaculate, sometimes with pale green median stripe. Hemelytra whitish with big rounded green dots, green coloration may be absent due to poor conditions of specimens, tip of cuneus with small and distinct dark green dot, membrane pale, diffusely embrowned towards apex, membranal cells immaculate, veins green. Femora yellow, anterior and middle ones immaculate, posterior one with more or less distinct green maculation on dorsal surface, tibiae yellow with green dot at femoral joint, posterior one sometimes with additional longitudinal green stripe on distal third.
Vestiture: General vestiture consists of long, dense and semi-erect silvery setae. Head with long, dense and erected silvery setae. Antennae covered with very short adpressed pale setae. Pronotum, scutellum and hemelytra covered with long, dense and semi-erect silvery setae, additionally, hemelytra bear occasional long and erect dark hairs. Tibiae with pale spines which are slightly longer than width of tibia.
Structure: Length 3.4–3.8 mm, body oblong-ovate, 3.5 × as long as width posterior margin of pronotum. Head transverse, 2.7 × as wide as long, 0.6 × as wide as width posterior margin of pronotum, ocular index 2.5. Antennae long, 0.8 × as long as body length, first antennal segment 0.5 × as long as diatone, second antennal segment 1.2 × as long as width posterior margin of pronotum, ratios of antennal segments 16: 48: 29: 20. Pronotum strongly trapezoid, posterior margin 2.0 × as wide as anterior one, 1.8 × as wide as long, lateral margins and basal margin straight. Hemelytra sub-parallel sided, slightly enlarged towards distal of corium, at widest part 1.3 × as wide as basal width, largely exceeding abdomen. Genital opening simple, without sclerotized spine, left paramere Y-shaped, unarmed, apical process only slightly shorter than lateral process, latter apically blunt (Fig. 3C). Right paramere curved in middle, apical process bent 90 degrees inward, armed sparsely with small dents on entire surface, lateral process fan shaped, armed with small teeth along apical margin (Fig. 3 D–E). Vesica with four sclerotized processes as in Fig. 3 F–G.
Description of female: Habitus Fig. 3B. Body length 3.4–3.6 mm. Very similar to male in coloration, vestiture and structure but ocular index 2.6–3.0 and second antennal segment 1.3–1.6 × as long as width of posterior margin of the pronotum.
Host plant: Many of the specimens were collected from Quercus sp.
Comment: R. winkelmanni was described from Antalya by Günther & Strauss (2018) based on a well preserved single male specimen. They distinguished their new species from all other species of the genus mainly based on the unique shape of the parameres and the vesical processes. We examined 16 specimens collected from Antalya and Mersin which were previously identified as R. marqueti by Lodos et al. (2003). Our examination showed that all these specimens in fact belong to R. winkelmanni. We also had the chance to examine the previously undescribed female of R. winkelmanni. Females of Reuteria are very similar to males in most aspects, as expected, females of R. winkelmanni are very similar to males and differ from them in the small morphological ratios mentioned above.
