Proceedings of the American Academy of Arts and Sciences 48: 157 ( Thaxter 1912a, as D. Corynitis). –

Type: “ On the elytra of CorYnites ruficollis Fabr. , La Plata, No . 1459 ”; FH. [ Argentina]

Diagnostic features

Male thalli consisting of 5–8 superposed cells separated by horizontal septa, bearing lateral flask-shaped compound antheridia, and an apical unbranched, unicellular, rounded primary appendage ( Fig. 71D View Fig , pa). Female thalli consisting of 4–6 superposed cells separated by horizontal septa. The 2nd and/or 3rd cells bear a unicellular secondary appendage ( Fig. 71A View Fig , arrow). The 3rd and/or 4th cells give rise to perithecia. The uppermost cell supports a long, multicellular, unbranched secondary appendage and the rounded primary appendage ( Fig. 71A View Fig , *).

Distribution and hosts

This species has been reported from Argentina (type), USA ( Thaxter 1924), United Kingdom ( Hincks 1960), France ( Balazuc 1974f), Italy ( Rossi 1975), Spain ( Santamaria 1994), Poland ( Majewski 2006), Sweden ( Huggert 2010), and Czech Republic ( Rossi et al. 2019b). Occurs on Necrobia (= Corynetes ) (Col. Cleridae ).

Remarks

First record from Denmark. This species shows a patchy distribution likely due to lack of investigation, probably because the capture of its hosts is complicated by its specialized habitat, viz., in rotting corpses and other unpleasant-smelling substances such as rotting grains where they feed on the meat-infesting larvae of blow flies ( Calliphora Robineau-Desvoidy, 1830 , Diptera Calliphoridae ), Dermestidae (Coleoptera) and Piophilidae (Diptera) . The cells above the basal cell may undergo divisions giving rise to additional secondary appendages or perithecia.
