Phasmidiasta Wharton, 1980: 63; Belokobylskij 1998: 169, 294-296; Fischer 2006: 628. Type species (by original designation): Phasmidiasta lia Wharton, 1980 [holotype (CNC) examined].

Notes.

The biology of this Holarctic genus is uncertain. It is likely a parasitoid of xylophilous fly larvae ( Wharton 1980). Only two species are known: P. effecta Belokobylskij, 1998, occurs in the Eastern Palaearctic region (reared from a cocoon in a bark beetle gallery ( Belokobylskij 1998) and the type species in the Nearctic region. The Neotropical P. ecuadorensis Fischer, 2006, does not belong in Phasmidiasta and is transferred to Neodiasta van Achterberg, gen. nov. (see above) and P. malaysiae Fischer, 2006, was transferred to Separatatus by Yao et al. (2018a). The species remaining in Phasmidiasta are very similar and may be separated as follows:
