Key to males of Palearctic Protearomyia McAlpine, 1962 .

1. Epandrium without an obvious ventral lobe, hypoproct wider than long, in form of a disc, prensisetae absent. ( Figs. 27–29 ) ( greciana group)..................................................................................... 2

- Epandrium with a square or rectangular ventral lobe, hypoproct not disc shaped, prensisetae present. ( Fig. 1–2 ).......... 3

2. Apical lobes of hypoproct with finger-like projections laterally, outer margin of surstyli obviously serrated. Phallus thickened with basal processes. ( Figs. 27–31 )......................................... hermonensis MacGowan & Freidberg.

- Apical lobes of hypoproct rounded, without processes, surstyli with multiserial rows of denticles along outer margin and

extending over posterior surface. Phallus narrow and sinuous. ( Figs. 22–26 )....................... greciana McAlpine. 3. Ventral lobe of epandrium higher than wide, hypoproct with two square ended apical projections and obvious lateral processes, phallic guide without anterior projections ( Figs. 18–21 )........................................... nigra (Meigen)

- Ventral lobe of epandrium square or wider than high, apex of hypoproct not as above phallic guide with a pair of anterior projections ( Figs. 13 & 17 ) ( withersi group).................................................................. 4

4. Apex of hypoproct broad, with serrated apical margins and small lateral processes, phallus with non-sclerotized apical section extending almost at right angles to the basal plate. ( Figs. 1–6 )...................................... iberica sp. nov.

- Apex of hypoproct and phallus not as above................................................................ 5

5. Hypoproct apically with two narrow, parallel processes, phallus U-shaped with an elongated apex at right angles to the basal plate. Outer margin of surstylus with only slight projections. ( Figs. 7–12 )............................. rameli sp. nov.

- Hypoproct apically with two obviously diverging claw–like processes, phallus small, with apical portion emerging directly from and extending at right angles to the basal plate. Outer margin of surstyli obviously serrated along entire length. ( Figs. 13–17 )................................................................................ withersi sp. nov.
