PARATYPES: 3 females with the same labels as the holotype. The holotype and 1 paratype are deposited at the PHMB, 2 paratypes at the AIBU collection.

Material examined. Three galls were colllected from Gümüşhane Şiran, N 40 ° 176.39´, E 39 ° 138.61´, 1390 m a.s.l., 28.08.2012; 1 gall—from Muş Karakütük 11.09. 2012, N 38 ° 633.47´, E 41 ° 704.46´, 1337 m a.s.l.; 2 galls—from Muş Azıklı, N 38 ° 643.04´, E 41 ° 753.69´, 1366 m a.s.l., 11.09.2012; 2 galls—from Bitlis Yeniünaldı Village, N 38 ° 317.59´, E 42 ° 020.99´, 1297 m a.s.l., 13. 0 9.2012.

Etymology. Named after the westernmost protrusion of Asia, Asian Turkey, where it was collected.

Diagnosis. By the presence of short, faintly oblique setae on the anterior surface of fore tibia, Andricus anatolicus , new species, belongs to the “Adleria kollari ” group of species (Melika 2006). Within this group of species, based on some characters: propodeal lateral carina are curved outwards in the middle, notauli are uniformly deep, complete, always reaching the pronotum, the head and mesosoma are light brown to amber; this species most closely resembles A. kollari (Hartig) . However, in A. anatolicus the mesoscutellum is dull rugose only along sides and delicately coriaceous in the anteromedian part; scutellar foveae delimited by carina all around, deep, black, with shiny, glabrous bottom; propodeal lateral carinae only slightly curved outwards in the middle; the prominent part of the ventral spine of the hypopygium 7.0 times as long as broad, while in A. kollari the mesoscutellum is uniformly dull rugose; scutellar foveae not delimited posteriorly by a carina, shallower, amber brown, with an alutaceous bottom; propodeal lateral carinae strongly curved outwards in the middle; the prominent part of the ventral spine of the hypopygium only 3.5–5.5 times as long as broad

Based on the mitochondrial cytb gene sequence it is most closely resembles A. kollari (see Comments below). The galls induced by the two species are also different.

Metasoma slightly longer than head+mesosoma, higher than long in lateral view, smooth, shiny. All metasomal tergites with very dense white setae laterally, which absent dorsally on all tergites; prominent part of ventral spine of hypopygium slender, needle-like, around 7.0 times longer than broad, with two ventral rows of dense setae directed downwards.

Body length 4.5–5.2 mm (n= 4).

Gall ( Figs 27–30 View FIGURES 27 – 30 ). A monolocular gall, found mainly on terminal buds and less frequently on lateral buds. The gall is greenish when growing and becomes brown when mature, 6–11 mm, often found in aggregated groups. The base of gall is broad, through the apex becomes gradually narrow and gives dome-like shape.

Biology. Only the asexual females are known to induce galls on Q. macranthera and Q. infectoria . The gall develops through the summer and matures in October. Our wasps emerged from the galls in September.

Comments. The mitochondrial Cytb gene sequence most closely resembles that of A. kollari (query cover 95 %, max. identity 99 %, accession # AJ 228466.1).

Distribution. Currently known from the vicinitites of Muş, Bitlis and Gümüşhane cities of Turkey.
