Bulletin de la Société d’Histoire Naturelle de l’Afrique du Nord 11(8): 132 ( Maire 1920). – Type: [Type lost?!] “Sur un tibia de Trogophloeus Mannerheimi Kolen. : C. Bône, embouchure de la Seybouse, mars 1918 (De Borde)”. [ Algeria]

Cantharomyces japonicus K.Sugiy. (1973: 20) [MB#310380]

Diagnostic features

Cell II very large, elongate, almost entirely blackened, broadened distally. Cells I and II separated by a ± constricted septum; forming a geniculate stalk. Appendage basal cell very large, inflated, subspherical, forming the base of several short and crowded branchlets borne from many packed small cells. [Detailed descriptions: Majewski 1994b; Santamaria 2003]

Distribution and hosts

On Thinodromus , a host genus name reported also as Trogophloeus or Carpelimus Leach, 1819 (Col. Staphylinidae Oxytelinae ). Trogophloeus is now a synonym or a subordinate name of Carpelimus with a rank of a small subgenus. Thinodromus once was a part of Carpelimus . Type from Algeria, it has been reported from Europe: Italy ( Rossi & Cesari Rossi 1978), Poland ( Majewski 1986a), Spain ( Santamaria 1989), Sweden ( Santamaria et al. 1991), France ( Duverger 1995), Greece ( Castaldo et al. 2004), and Slovakia ( Rossi et al. 2010). Cantharomyces japonicus has been reported on Carpelimus and Thinodromus from Japan (type) and on Carpelimus from China ( Shen & Ye 2006).

Remarks

First record from Denmark. The finding of this species in Denmark is not surprising considering its presence in neighbouring countries.
