Further Dilophus specimens

Specimens belonging to the genus Dilophus are scarce but present from many of the localities. Unfortunately, important diagnostic features such as the shape of male terminalia, antennae and protibiae are rarely preserved, thus it is not advisable to describe new species based on this material.

The genus has been noted from the following localities:

Céreste: EEFN F 312 (male, 6.7 mm). This specimen was listed by Théobald (1937: 404) as Bibio detractus . Chadrat: MNHN Chadrat P10 (female, 8 mm).

Monteils: MNHN Monteils 148 (male, 4.3 mm), Monteils 159 (female, 8 mm). Bois d’Asson: RGL Bois d’Asson 43 (female, 6.0 mm).
