The Hercostomus exarticulatus species group in the Palaearctic Region (Diptera: Dolichopodidae)

The Hercostomus exarticulatus species group in the Palaearctic Region (Diptera: Dolichopodidae)

The Hercostomus exarticulatusspecies group in the Palaearctic Region is defined and reviewed. It comprises 4 species belonging to the nominotypical Hercostomus longiventris lineage. The species group is differentiated from other Hercostomus by the male mid femur bearing ventral tubercle at base, one...
