Revision of the morphology, phylogenetic relationships, behaviour and diversity of the Iberian and Italian ant-like Tachydromia Meigen, 1803 (Diptera: Hybotidae)

Phylogenetic inference, based on five molecular markers (COI, 28S, AATS, 12S, PGD), corroborates the synonymy of flightless genera Pieltainia Arias, 1919 and Ariasella Gil, 1923 with Tachydromia Meigen, 1803. The secondary structure 28S rRNA gene is used for first time in this family to align multiple sequences. Molecular morphological data are largely congruent all known species Tachydromia. This paper treats ten western Mediterranean (nine Iberian one Italian) detail, including description four new species: T. ebejeri Gonçalves, Grootaert & Andrade sp. nov., stenoptera cantabrica nov. nigrohirta male pieltaini (Gil Collado, 1936) female apterygon Plant Deeming, 2006 described time, while a lectotype assigned pandellei (Séguy, 1941).
