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.

pone.0117434.g010: Morphology of Elephantomyia (E.) longirostris [9], No. 1089–6: A. body, latero-dorsal view; B. wing venation; C. hypopygium; D. wing apex.Abbreviations of male hypopygium features as in Fig. 9.

Mentions: Head: rostrum 2.66–4.20 mm long, approximately equal to body length, longer than abdomen length, only one-fifth shorter than wing (Fig. 9C). Antenna (Figs. 9A, 10A) relatively short, 0.80–1.11 mm, 15-segmented; flagellar segments crowded; scape elongate; pedicel wide; flagellomeres 2–15 elongate; first flagellomere very short, crowded with previous segments; final segments elongate, narrowed at apex; antennae with four elongate setae on each flagellomere; setae much longer than length of segments bearing them; palpus (Fig. 9B) elongate, 4-segmented, final segment short, other segments elongate and cylindrical, system of small microtrichia clearly visible on all segments.
