My previous post covers most of the issue. But I guess to simplify - the name Lycia R-D (1830) is a junior primary homonym of Lycia Hubner (1823). That makes Lycia an invalid name. Collin gave the new name Lyciella to this genus-group taxon in 1948. This was after Hendel (1925) had erected the genus Meiosimyza. The name of Hendel (1925) has priority over that of Collin (1948), because it was described first. For nomenclature, the priority is established by date of publication, not date of the taxon concept (i.e., of Lycia R-D). So, when Meiosimyza and Lyciella are considered to represent the same genus, Meiosimyza is the senior name for purposes of priority. So in the absence of dividing Meiosimyza into subgenera, Lyciella would be a simple junior synonym. But since Meiosimyza is divided into subgenera, Lyciella is a subgenus of Meiosimyza. The various databases (e.g., Fauna Europaea) have this particular item wrong, listing the species as Lyciella. The only way that Lyciella would be a valid genus name is if it did not contain Sapromyza platycephala (the type species of Meiosimyza) - in other words, if Lyciella and Meiosimyza were separate genera.
