Habit:

Description of adults: : "Frontal tuft pale orange. Antennae pale brown. Eye-caps and collar cream. Palpi cream. Thorax and forewings uniform, greyish brown. Cilia and hindwings approximately as forewings in colour." (Puplesis 1991).

Distribution:

The species has been described from the lower Volga valley (Puplesis 1991) and is known also from Turkmenistan (Nieukerken 2018).

Larva. The larvae mine the leaves of iUlmus carpinifolia (= Ulmus minor).

Mine. The mine ist a contorted gallery. The early mine is completely filled with brownish frass, later the mine is gradually widening with coiled frass, leaving wide clear margins. Finally, the frass is deposited in a dark narrow line (Puplesis 1991).

genitalia. "Valva narrow medially and apically, strongly broadened basally. Transtilla with short sublateral processes. Juxta present, its form resembles a triangle apically. Uncus approximately with trapezium shape, with slightly tapering angles. Gnathos with two thin and long posterior processes. Transverse bar of gnathos narrow. Aedeagus narrowing in middle (in lateral view). Vesica with two groups of cornuti; one of which is larger and situated in middle, a smaller group is situated apically. Cornuti more or less in form of sclerotized spines, some cornuti have different forms." (Puplesis 1991)

genitalia. Unknown.

Diagnosis:

Following Puplesis (1991), the species is very similar to Stigmella ulmiphaga (Preissecker, 1942) and Stigmella ulmivora (Fologne, 1860). In the male genitalia however, it is easily distinguished by the valvae, which are abruptly broadened at the base. The cornuti are not numerous, the lateral lobes of the vinculum are broad in contrast to S. ulmivora.
