Differential diagnosis.

Males are easily distinguished from Megaselia subnitida  by the triangular-shaped lighter patch on the base of the hind femur. Megaselia lucifrons  also has a shiny frons (hence its name), whereas the frons is matte in Megaselia subnitida  . Males can be distinguished from Megaselia albalucifrons  by the broader left lobe of the hypandrium (Fig. 6a). The lobe is also darker in Megaselia lucifrons  than in Megaselia albalucifrons  . The left side of the epandrium has long thin hairs at the lower apical part that are typical for the species (Fig. 5a).


Megaselia lucifrons  is widely distributed in Sweden and has been found in all 29 SMTP traps from which we have studied material. The species is also reported from many other European countries (e. g. Prescher et al. 2002; Brenner 2004; Schmitz 1928; Durska et al. 2010; Schmitz 1934; Bonet et al. 2011), however, for findings after 1988, when Megaselia subnitida  was synonymized with Megaselia lucifrons  , it is often impossible to determine from the literature alone whether the records refer to Megaselia lucifrons  or Megaselia subnitida  .


Material from the SMTP shows that Megaselia lucifrons  likely has two generations per year (Fig. 8), alternatively the flies overwinter as adults, as has been found for a number of other Megaselia  species ( Disney 1994). Megaselia lucifrons  is found in different kinds of habitats from the SMTP, often in connection to trees or forest (Suppl. material 1).
