Fig. 38A–D

Karstenia 23: 57 ( Huldén 1983). –

Type: “ Holotype. Slide L. Huldén 4, Collecting data of the host: U.S.S.R. Murmansk Region: Konozero, leg. Edgren. Host. Bembidion transparens (Gebler) ( Coleoptera, Carabidae ). The parasite was found on the right elytron of the host”; MZH. [ Russia]

Diagnostic features

Receptacle distinctly constricted at the septum between cell II and cells III/VI ( Fig. 38A–C , arrows). Cell II inflated and broadest halfway up. Cell V oval, large, shorter than cell IV, not connected with cell III. Outer appendage simple to slightly branched, not exceeding the perithecial apex, with the basal cell separated from cells above by a moderately darkened septum. Inner appendage consisting of a few branches terminated by solitary antheridia ( Fig. 38D ). Basal cell of inner appendage shorter or similar than basal cell of outer appendage, which also has a darkened septum above. [Detailed description: Majewski 1994b]

Distribution and hosts

After its description from Russia, L. murmanica has been found on species of Bembidion (Col. Carabidae ) from Poland ( Majewski 1990b), United Kingdom (Weir 1996), Belgium ( De Kesel 1998), Lithuania ( Markovskaja 2004), and Denmark ( Høier 2009).
