Description

Adults are brown, sometimes yellowish gray, medium-sized crane flies with body length 4.0–9.0 mm. Antennal flagellum beaded. Mesonotal prescutum without tuberculate pits and pseudosutural foveae. Wing unpatterned or at most with darkening along cord, vein Sc long and nearly reaching branching point of Rs; sc-r before base of Rs; radial sector long and straight, situated very close to R and nearly parallel to it; R 2 indistinct, slightly beyond fork of Rs; discal cell open due to the atrophy of basal part of M 3; m-cu close to the branching point of M; anal angle widely rounded. Male terminalia large with transverse ninth tergum, elongate gonocoxite bearing two terminal gonostyles, and straight and short aedeagus. Ovipositor elongate and sclerotized with strongly raised apex of cercus.

Larva depressed dorsoventrally. Head capsule heavily sclerotized, with complete hypostoma. Frons fused with internolateralia, which are considerably shorter than externolateralia. Abdominal segments II–VII with dorsal and ventral creeping welts. Spiracular field surrounded by four lobes.

Pupa with large, ear-shaped pronotal horns. Sheaths of legs reaching sixth abdominal segment. Abdomen with dorsal and ventral transverse rows of spines.

Savchenko (1989) placed the genus Elliptera into the tribe Antochini based only on adult characters. Phylogenetic relationships of the family Limoniidae , including Elliptera , based on larval and pupal characters were analyzed by Oosterbroek & Theowald (1991), using a nonquantitative analysis. The final tree placed Elliptera as the sister group to the unresolved Atypophthalmus - Discobola lineage based on the presence of larval creeping welts on abdominal segments 2–4 in these genera, with the genus Antocha Osten Sacken, 1860 placed as sister group to the rest of the Limoniinae based on a weak synapomorphic character of oblong-shaped, obliquely placed spiracles (spiracles lost in Antocha ).
