Male. Forewing length 1.80—1.92 mm (2), wingspan 4.0 — 4.2 mm. Head: frontal tuft and collar yellowish
white. Antennae with 35 — 37 segments (2). Thorax and forewings ochreous-brown, with a medial, often
ill-defined, straight fascia, colour yellowish white. Underside of forewing with a group of brown androconial
scales in distal half, and a group of short, yellowisii-white lamellar scales near costal retinaculum. Hindwing
with a yellowishwhite hair-pencil of 1/4 hindwing length; basal 2/3 covered with brown lamellar, special scales.
Female. Forewing length 1.58 — 1.80 mm (3), wingspan 3.8 — 4.1 mm. Antennae with 23 — 25 segments (3).
Underside forewing and hindwing without special scales. Male genitlia. Capsule very short, length 150 — 167
µm (3). Tegumen produced into ventral globular pseuduncus. Gnathos with central element broad and truncate,
in form of a transverse bar. Valva length 133 — 150 µm , basally broad, below middle suddenly narrowed and
inner margin becoming concave towards tip; outer margin uniformly convex. Aedeagus 244 — 279 µm (3), more
than 1.5 X as long as capsule, carinae single, pointed. Female genitalia. T7 without long setae. T8 small, with few
scales laterally and with 8 — 14 setae. Anal papillae with 6 — 8 setae. Vestibulum with vaginal sclerite,
slightly different from that in other species and a spiculate pouch with very few small spines, without pectinations.
Corpus bursae small, 310 — 350 µm , covered with many pectinations, except distal part; signa similar, oval,
189 — 223 µm (209.3 ± 14.9, 6), 2.0 — 2.3 x as long as wide. Ductus spermathecae with 3 — 3 1/2 convolutions.
Larva emerald green, head-capsule brown. No ventral plates (Klimesch, 1978).
Hostplants: Quercus ithaburensis Decne subsp. macrolepis (Kotschy).
Only known from Greece: Rhodos, to be expected in Turkey. Old leafmines, found in mainland Greece (Lakonia), may be this species, but since E. heringi also occurs on the same host and may have rather similar mines, we cannot record it definitely from mainland Greece.
Larvae found in September, adults reared in April, in the field collected in August, suggesting a second generation.
