The Arganthomyza socculata group

The A. socculata group was characterized by ROHÁĆEK & BARBER (2013). Its monophyly is considered to be well supported by the following apomorphies: (1) nlum of distiphallus seemingly with single sclerite (with two original sclerites completely fused); (2) apex of nlum spinulose; (3) spermathecae with unique bell-shaped appendages. The A. socculata group is hypothesized to be the sister group to the A. duplex group by ROHÁĆEK & BARBER (2013: Fig. 173 ), connrmed by molecular data analysis ( ROHÁĆEK & TÓTHOVÁ 2014). Two species are included: A. socculata (Holarctic) , A. disjuncta (Nearctic) .
