Diagnosis.

This species is characterized by the forewings with numerous pale brown spots and by the male gonocoxite complex 9, 10 and 11 with short, feebly sclerotized ninth gonocoxite and elongate, blade-like tenth gonocoxite.

Description.

Male. Length of forewing 11.0-12.2 mm, of hindwing 9.5-10.3 mm.

Head pale yellowish brown, with pale yellow setose tubercles. Compound eyes blackish brown. Antenna with ca. 29 segments, pale yellow, with scape and pedicel pale brown, flagellum unipectinate on most flagellomeres, medial branches much longer than those on both ends, longest branch nearly 3.0 times as long as the corresponding flagellomere, but branch of 1st flagellomere short and dentate, distal eight flagellomeres simple.

Prothorax pale yellowish brown, pronotum dark brown with several hairy yellowish tubercles; meso- and metathorax yellow, each notum laterally with a pair of broad, brown markings and a pair of pale brown narrow stripes; mesonotum medially with a pair of additional brown markings near anterior margin. Legs pale yellow, with femora blackish brown at tip. Wings hyaline, slightly yellowish brown, with numerous pale brown spots. Forewing ~2.5 times as long as wide, densely spotted, with markings slightly darkened toward anal region; a few markings on posteroproximal area connected with each other, forming short transverse stripes; an immaculate area present distal to median nygma; two nygmata present on proximal portion, both slightly smaller than median nygma. Hindwing ~2.1 times as long as wide, slightly paler than forewing, with dark markings largely reduced; one nygma present at middle. Veins pale yellowish brown; Rs with four main branches on both fore- and hindwings.

Abdomen pale yellowish brown, pregenital segments dorsally brown. Ninth tergite in dorsal view with nearly truncate anterior margin and a deeply V-shaped posterior incision, leaving a narrow median portion and a pair of subtriangular hemitergites, which are obtuse and slightly incurved distally; in lateral view broad, with straight ventral margin and arcuate posterior margin. Ninth sternite obviously shorter than ninth tergite, with nearly truncate posterior margin. Ectoproct in dorsal view with a pair of digitiform projections, posteroventrally with a pair of subsemicircular and flattened lobes, a pair of bifid unguiform projections and a pair of short, feebly sclerotized, digitiform projections. Ninth gonocoxite short, shield-like, mostly membranous and transparent, with sclerotized lateral margin and with a strongly narrowed, obtuse apex; tenth gonocoxite slenderly elongate, blade-like, nearly 2.5 times as long as ninth gonocoxite, straightly directed posteriorly with median portion feebly curved; fused eleventh gonocoxites (= gonarcus) beam-shaped, laterally connectedto base of ninth gonocoxites. Hypandrium internum subtriangular, with lateral margins slightly arcuate.

Female. Length of forewing 10.9 mm, of hindwing 10.0 mm.

Seventh sternite in lateral view subtrapezoidal. Eighth abdominal segment without subgenitale. Basal part of bursa copulatrix sac-like, nearly rhomboid in ventral view, proximally membranous and strongly rugose, distally sclerotized into a pair of lateral sclerites and a median ridge. Ectoproct rather small, ovoid.

Distribution.

Turkey: Western, central, and southern parts of Anatolia (Fig. 31); supposedly reaching Syria or Lebanon to the south.

Etymology.

Adjective, masculine, nominative, singular; an attribute to the genus name. From lat. anatolicus 3 = referring or belonging to Anatolia, the Asian part of Turkey.

Remarks.

Dilar anatolicus sp. n. can be distinguished from all other western Palaearctic species of Dilar based on the slenderly elongate male ninth gonocoxites and the short, largely membranous male tenth gonocoxites. In appearance, Dilar anatolicus sp. n. looks similar to its co-existing Turkish species Dilar turcicus , but it can be easily distinguished from the latter by the male ninth tergite without median projection and by the different shape of sclerotization of the female bursa copulatrix. Interestingly, Dilar anatolicus sp. n. appears to be closely related to Dilar sinicus Nakahara, 1957, which is distributed in northern China ( Zhang et al. 2014a), by having the similar male gonocoxites 9, 10 and 11 with short, shield-like ninth gonocoxite and slenderly elongate tenth gonocoxite. However, in Dilar anatolicus sp. n. the male ninth gonocoxite is largely membranous and transparent with obtuse apex, while in Dilar sinicus the male ninth gonocoxite is entirely sclerotized with acutely pointed apex. Possibly Dilar anatolicus sp. n. occurs sympatrically with Dilar syriacus (see under Dilar syriacus ).
