Type: “ Spain. Barcelona: Sant Boi de Llobregat , on abdomen and elytra of Euplectus duponti Aubé ( Coleoptera, Pselaphidae ), X.1934, leg. M.Z.B., BCB-Mycotheca SS·1153d (Holotypus)”; BCB.

Diagnostic features

Appendage unbranched., with the 3–5 lower cells and cell III darkened towards the outer margin. Cells II and III ± parallel, separated by an almost vertical septum. Cell III in contact with cell I. [Detailed description: Santamaria 2003]

Distribution and hosts

Only known from the original description on Batrisodes Reitter, 1882 , Euplectus Leach, 1817 and Plectophloeus (Col. Staphylinidae Pselaphinae ) in “Transcaucasia”, Belgium, France, Spain (type) and Italy. Later, only reported once again from Belgium ( De Kesel 1997).

Remarks

First record from Denmark. Bibloplectus ambiguus is a new host for the species. Cryptandromyces euplecti is easily distinguished by the dark brown pigmentation in the base of the appendage extending to the cell III. Antheridia are unknown. Perithecial lips protrude through a break as occurs in C. cryptophagi sp. nov. and species of Troglomyces ( Fig. 51E , arrows), the latter defined by Enghoff & Santamaria (2015).
