Redescription. Habitus as in Fig. 16. 7.0–10.0 mm; length from apex of mandibles to posterior margin of elytra: 4.0– 4.8 mm. Coloration: head, pronotum, and abdomen blackish; elytra paler reddish brown to blackish brown, with the humeral angles and the narrow posterior margins usually paler, yellowish brown; legs yellowish brown to reddish brown; antennae reddish, with antennomeres IV–X brown.
Head approximately 1.25 times as long as wide, weakly widened posteriad; dorsal surface glossy, with a mixture of rather sparse finer and slightly coarser punctures; with or without traces of microsculpture; frontal furrows distinct, parallel, not reaching pair of frontal punctures; eyes moderately large and weakly prominent, approximately 1/3 the length of postocular region in dorsal view (Fig. 17).
Pronotum about 1.4 times as long as wide and approximately as wide as head, widest at anterior angles and moderately tapering posteriad; dorsal series composed of 10–15 punctures; disc without microsculpture (Fig. 17).
Elytra at suture approximately 0.75 times as long as pronotum; puncturation moderately coarse and rather dense, interstices on average as wide as or slightly wider than diameter of punctures; without distinct microsculpture (Fig. 17). Hind wings apparently fully developed.
Abdomen slightly narrower than elytra, widest at segment VI; puncturation fine and moderately dense; all tergites with shallow transverse microsculpture; posterior margin of tergite VII with palisade fringe.
ɗ: posterior margin of tergite VIII weakly concave in the middle (Fig. 18); sternite VIII posteriorly with membranous margin and broadly concave (Fig. 19); internal sac of aedeagus with long and weakly sclerotised tube, distally with several short series of sclerotised spines (Figs. 20–21).
Distribution and bionomics. Xantholinus gridellii has been recorded from various countries in the Middle East (Israel, Lebanon, Syria, Cyprus) (Coiffait 1956a, 1972, Herman 2001, Smetana 2004). The species has also been reported from Algeria (Bordoni 1976a, Herman 2001, Smetana 2004), but this record seems doubtful and requires confirmation. The specimens from Gaziantep represent the first record of this species from Turkey; X. gridellii carius Coiffait, 1972, which was described from southwestern Turkey, was recently synonymised with X. graecus Kraatz, 1858 (Assing 2006a). All the additional material listed above was found at lower altitudes, at least partly in unforested habitats.
