Bottom Line: In addition, two new species of the genus are described: Elephantomyia bozenae sp. nov., and Elephantomyia irinae sp. nov.All these fossil species are placed within the subgenus Elephantomyia.A key to the extinct species of Elephantomyia is provided, and the genus' ecological pattern and evolutionary aspects are discussed.

ABSTRACT
A revision of the genus Elephantomyia Osten Sacken (Diptera: Limoniidae) from Baltic amber (Eocene) is presented. Four species--E. baltica Alexander, E. brevipalpa Loew, E. longirostris Loew, and E. pulchella Loew--are redescribed and documented with photographs and drawings. In addition, two new species of the genus are described: Elephantomyia bozenae sp. nov., and Elephantomyia irinae sp. nov. All these fossil species are placed within the subgenus Elephantomyia. A key to the extinct species of Elephantomyia is provided, and the genus' ecological pattern and evolutionary aspects are discussed.

Abbreviations: male terminalia: gx—gonocoxite; ing—inner gonostylus; intb—interbase; oug—outer gonostylus.

Mentions: Head: rostrum elongate, 2.14 mm long, shorter than wing, ending just after half wing length, rostrum longer than abdomen (Fig. 2C). Antenna (Figs. 2A, 3D) small, 0.53 mm long, 15-segmented, flagellar segments crowded; scape cylindrical, widened; pedicel wide; first flagellomere elongate; second flagellomere very short, crowded with first flagellomere; flagellomeres 5–15 elongate; the last one flagellomere widened at apex; antennae with two elongated setae on each segment of antennae; palpus (Figs. 2B, 3B) elongate, 0.20 mm long, 4-segmented, the last segment short, other segments elongate. System of small microtrichia clearly visible on all segments.
