Phylidorea (Macrolabina) Savchenko, 1986

Phylidorea (Macrolabina) Savchenko, 1986: 20 ; 1989: 103.

Type species - Limnobia nigronotata Siebke, 1870 , by original designation (Palaearctic).

Adult.

Medium-sized crane flies with body length 9.0-10.0 mm, wing length 9.0-10.0 mm. Body coloration dark brown or gray.

Head: Apical flagellomere of male antenna large, nearly as long as preceding segment.

Thorax: Prescutal stripes and spots on scutal lobes distinct, polished dark brown or black. Wing with dark spots along frontal margin, stigma distinct, dark.

Abdomen: Gonocoxite with very large elongate blunt-apexed, sometimes bilobed, dorsal lobe ( Fig. 1B ) is the main diagnostic character of subgenus. Aedeagus short, straight, always with simple distal part.

Subgenus has only Palaearctic distribution. It includes only six species, five of which are recorded from the Eastern Palaearctic ( Oosterbroek, 2021). No fossil species are ascribed to this subgenus ( Evenhuis, 2014).

Larva and pupa generally as in the characters of the genus mentioned above.
