Checklist of the smaller families of Opomyzoidea, Anthomyzidae, Asteiidae, Aulacigastridae, Clusiidae, Odiniidae, Opomyzidae and Periscelididae (Diptera) of Finland.

A species checklist is presented for Finland covering seven smaller families of Opomyzoidea: Anthomyzidae, Asteiidae, Aulacigastridae, Clusiidae, Odiniidae, Opomyzidae and Periscelididae (Diptera).

Introduction

The superfamily is likely to be para- or polyphyletic (see Wiegmann et al. 2011). It has long been used as a dumping grounds for acalyptrate taxa that do not fit well elsewhere. As such, the superfamily is poorly defined and hardly any two authors agree on its definition. includes one large family (, the leaf-mining flies, with over 3000 described species) and more than a dozen small families. The exact number of recognized families varies. The are treated PageBreakelsewhere in this volume of ZooKeys. The remaining opomyzoid families are presented here in alphabetical order.

Hackman (1980) last listed the Finnish species of these families. World catalogues have recently been published for (Mathis and Rung 2011) and (Gaimari and Mathis 2011). For the Revision of West Palearctic by Roháček (2006, 2009) is followed. Three of the four Palearctic species have been found in Europe (Kassebeer 2001, Rung and Mathis 2011). Papp and Withers (2011) reviewed the Palearctic and proposed some nomenclatorial changes. Hackman’s (1959) review of the Finnish opomyzid fauna is still valuable but several additional species have since been recognized.
