Holotype and paratype—missing

Type locality. Greece, Velouchi. ( Mount Tymfristos is a mountain in the eastern part of Evrytania and the western part of Phthiotis , Greece. The mountain is a part of the Pindus mountain range . The elevation of its highest peak, Velouchi, is 2315 m. Forests dominate the lower areas of the mountain, and the higher elevations are covered with grasslands.)

Material examined. 6 specimens.

Neotype (designated here): male, Greece, Halkidiki , Stratoni, 100 m, 2–7.05.1994, P. Stadel Nielsen leg., (abdomen in gelatine capsule), ZMUC.

Note. Following Art. 75.3 of the ICZN we, here below, state the following qualifying conditions:

(1) The neotype is designated with the express purpose of clarifying the taxonomic status of Eidophasia zukowskyi Amsel, 1938 .

(2) The set of characters of the closely resembling species E. syenitella presented in Baraniak and Sohn (2015) show stable differences.

(3) The label data above and the redescription below ensures the recognition of the neotype specimen.

(4) The authors have consulted the curator of the Amsel’s collection, deposited in the Naturkundemuseum, Karlsruhe, which does not include the type specimens of E. zukowskyi . The type specimens E. zukowskyi could not be found.

(5) The illustrations and the redescription presented here are consistent with what is known of the former type of E. zukowskyi .

(6) Amsel, 1938 designated the type locality in Greece, Velouchi Mts. We chose as the neotype one male specimen collected also from Greece, Halkidiki by Stadel Nielsen.

(7) The neotype specimen is preserved in the collection of Statens Naturhistoriske Museum , Copenhagen, Denmark ( ZMUC). This scientific and educational institution, that maintains a research collection, has proper facilities for preserving name-bearing types, and makes them accessible for study.

Additional verified specimens: 1 male, 1 female, 19– 29.05.1955, Macedonia, Matka Treska Schlucht, J. Klimesch leg., ZSM; 1 male, without data, Macedonia, Krone leg., coll. Staudinger, genitalia slide 1135 as Eidophasia syenitella H.S. ssp. concinnella Christ. , det. G. Friese, 1965; 1 female, [without data] 1860, [ Greece], Parnass, coll Staudinger, genitalia slide 1136 as Eidophasia syenitella H.S. ssp. concinnella Christ. , det. G. Friese, 1965, MHB ; 1 male, 9.0 6.2005, Bulgaria, Kumovgrad, J. Buszko leg., coll. EB.

Diagnosis. This species is similar to its congener Eidophasia syenitella (Herrich-Schäffer) but it differs from the latter in having the triangular patch at the middle of the forewing dorsum (bar-shaped in E. syenitella ). The genitalia features further support their distinctiveness as summarized in Table 1 .

Redescription. Forewing span 14–15 mm. Head brown, intermixed with white and fuscous, erect scales. Labial palpus with first segment pure white, second and third white, intermixed with fuscous scales; second segment slightly shorter than basal one, coloured similarly, with a long tuft of scales (longer than second segment); third segment short, straight, pointed. Maxillary palpus small, slender, curved, grey basally, with a large black patch apically. Antenna: scape and pedicel white; flagellomeres white, each with a thin black band. Forewing elongate, pointed at apex, brown, basal area of the same colour, only along dorsal margin a narrow and short, elongate, white-yellow patch, starting from wing base: two triangular white-yellow spots present near dorsal margin: first spot large, starting immediately before 1/2 of wing length, ending at 2/3 of wing length, spot edge straight near termen margin, oblique near basal area; second spot small, near distal end of dorsal margin; three small white-yellow spots present near costal margin: first one triangular, between patches along termen margin; remaining two spots narrow, very close to wing apex and each other, slightly curved towards wing base; cilia brown, with 2 small white spots at 1/2 length of termen margin. Hindwing and cilia dark grey, slightly darker near wing base. Thorax pale grey.

Male genitalia: anal tube long, membranous. Socii membranous. Saccus short, narrow, apically constricted and rounded, half as long as valva. Valva elongated, rectangular in outline, gently rounded apically; ventral margin of valva dilated at half its length, forming a sacculus, strongly sclerotized; sacculus club-shaped, margins conspicuously dentate (outer margin coarsely, inner margin finely), covered with short, distant spinules; dorsal margin of valva with numerous hair-like bristles, ampulla small, with thin spinules on apex. Aedeagus long and narrow, only 1/3 longer than valva, slightly tapering towards apex, vesica with no cornuti (spines). Ductus ejaculatorius membranous.

Female genitalia: Papillae annales short and wide, covered with thin spinules. Apophyses posteriores and anteriores short and thin. Antrum narrow, cup-shaped, only slightly wider than ductus bursae, markedly sclerotized. Ductus bursae short and wide, slightly dilated near inception of bursa copulatrix. Ductus seminalis membranous, emergent from bursa copulatrix close to ductus bursae. Corpus bursae oval, membranous only near ductus bursae entrance and ductus seminalis opening, in other parts considerably sclerotized, surface strengthened with numerous spines.

Distribution. Bulgaria, Greece, Macedonia.

Biology and host plants. Unknown.
