DIFFERENTIAL DIAGNOSIS: This new species is included in the genus Fulvius Stål because of its general appearance matching with the anthocoroides -group species of Fulvius, especially close to Fulvius oxycarenoides (Reuter, 1878) and Fulvius ussuriensis Kerzhner, 1973. The only species of this genus that distributes in Western Palaearctic region (excluding Azores and Canary Islands) is F. oxycarenoides. It was originally described from Greece and later found from Balkans, France, Italy, Spain in Europe, and Caucasian region of Russia, Azerbaijan, Georgia, Iran and Turkey in Asia (Reuter 1878; Reuter 1895; Linnavuori 2009; Aukema 2020). This species was recorded from Turkey from Adana (Hoberlandt 1956; Linnavuori 1965) and Kastamonu (Küçükbasmacı & Kıyak 2015), but the record of Hoberlandt (1956) was based on an erroneous identification of the holotype of F. anatolicus Çerçi & Gorczyca sp. n. as F. oxycarenoides. Considering the proximity of the collection site of this new species with Pozantı, Adana, it is possible that record of F. oxycarenoides by Linnavuori (1965) might also refer to the new species described here.
F. anatolicus sp. n. looks similar to F. oxycarenoides at first glance, due to similar colour pattern of hemelytra but differs from it in many ways: Second antennal segment unicolorous (basally dark brown and apically white in oxycarenoides) and slender (thicker than width of posterior tibia in oxycarenoides); head 1.3–1.4 times as long as wide (only 1.0– 1.2 in oxycarenoides); rostrum reaches to apex of abdomen (rostrum does not surpass posterior border of thorax in oxycarenoides), pronotum, scutellum and hemelytra without any tubercles, setae do not arise from tubercles (Fig. 5D) [these with distinct tubercles, from which setae arise in oxycarenoides (Fig. 5B)], posterior lobe of pronotum with dense short horizontal stripes (Fig. 3C, 6B) [posterior lobe of pronotum with dense tubercles in oxycarenoides (Fig. 4C, 6A)], setae covering pronotum, scutellum and hemelytra moderately dense (Fig. 5D) [setae covering them noticeably denser in oxycarenoides (Fig. 5B)], vesica with 6 sclerotized processes which are either straight or only slightly curved (Fig. 6I) [vesica with only 3 sclerotized processes, 2 of which are strongly curved in oxycarenoides (Fig. 6H)], outer margin of parieto-vaginal rings semicircular shaped (Fig. 6K) [these differently shaped in oxycarenoides (Fig. 6J)], posterior margin of dorsal labiate plate with a narrow and deep notch in the middle (Fig. 6K) [this without any notch in oxycarenoides (Fig. 6J)] (Sadowska-Woda et al. 2006). Comparison with F. oxycarenoides is based on a specimen of this species preserved in LEMT, which was collected from Comona, Romania by Montandon (Fig. 4) and the description provided by Wagner (1974). The very same specimen was mentioned by Reuter (1895) to be collected in 1892 and identified by himself as F. oxycarenoides. Among other species of Fulvius which are known to occur in Palaearctic Region, it is most similar to the Far Eastern species Fulvius ussuriensis Kerzhner, 1973 due to similar colour patterns of hemelytra, unicolorous brown second antennal segment and rostrum extending to apex of abdomen (Kim et al. 2019; Yasunaga & Nakagawa 2020). But F. anatolicus sp. n. also differs from this species by the following characters: head 1.3–1.4x as long as wide (head as long as wide in ussuriensis), vertex without any sulcus (vertex with a weak longitudinal sulcus in ussuriensis), eyes noticeably removed from pronotal collar (eyes adjacent to pronotal collar in ussuriensis), cuneus covered with setae, as the rest of hemelytra (cuneus without pubescence in ussuriensis) and vesica with 6 sclerotized processes which are either straight or only slightly curved (vesica with 4 sclerotized processes, 2 of which are strongly curved in ussuriensis) (Kim et al. 2019). It differs from all other species of this genus known from Palaearctic Region by second antennal segment being unicolorous. Table 1 summarizes differential diagnostic features between the new species, Fulvius oxycarenoides and Fulvius ussuriensis.
