Distribution:

The species is known from the type locality in Anatolia, Turkey (Klimesch 1978), but also from Greece (Karsholt & Nieukerken 2004).

Description of early stages following Klimesch (1978):

Egg. The egg is laid on the underside of a leaf.

Larva. Larva light yellow, head capsule alike. The larvae mine the leaves of Sanguisorba minor muricata (Spach) Focke. Mine a contorted corridor, first delicate with black frass line, almost completely filling the mine width. Later, the mine often follows the leaf margin and at last it covers a large part of the leaf with strong, partly dispersed frass line.

Pupa. The pupa rests in a delicate, oval, light brown cocoon.

genitalia. Uncus with medial notch and lateral appendages; gnathos with two diverging branches; ventral margin of valvae straight, apically with inwardly bent appendage; transtilla short; vinculum narrow, inwardly curved medially; aedeagus with many small cornuti.

genitalia. Not investigated.

Diagnosis:

The species is quite similar to Stigmella thuringiaca (Petry, 1904), but smaller, more delicate and lighter, especially in . In the male genitalia, the notch of the uncus in S. thuringiaca is more shallow, the two appendages being more peg-like. Furthermore, in this species the cornuti in the aedeagus are larger, thorn-like and a sclerotized plate is present too (Klimesch 1978).
