Outer appendage unbranched, up to 700 µm long, the 2–3 lower cells contrasting by their darker or paler colour from the cells above.

Basal cell of inner appendage slightly shorter than the outer. [Detailed descriptions: Majewski 1994b ; Weir 1994 ; Santamaria 1998 ] Distribution and hosts On Col. Carabidae of the genus Leistus . This is a species only known from Europe : Poland , Spain , France , Belgium , United Kingdom , Germany , Hungary , Romania , Finland ( Majewski 2008 ), Denmark ( Høier 2009 ), Switzerland ( Hoess & Senn-Irlet 2009 ), Sweden ( Huggert 2010 ), Czech Republic , Slovakia ( Rossi et al. 2010 ), and the Netherlands ( Haelewaters et al. 2012 ). De Kesel et al. (2020) reported L. leisti on Agonum muelleri from Belgium , a host record which requires confirmation. Collections examined from Denmark On Leistus ferrugineus (Linnaeus, 1758) (Col.
