[Detailed descriptions: Thaxter 1908 ; Majewski 1994b ; Santamaria 2002 ; Santamaria 2003 ] Distribution and hosts Widespread and known from all continents except Oceania. Occurs on Anthicus Paykull, 1798 and allied genera (Col. Anthicidae ) ( Santamaria 2002 ; Majewski 2008 ; Bernardi et al. 2014 ). Also in Korea ( Lee et al. 2011 ).

Remarks First record from Denmark . This is a very variable species, with numerous variations connected to one another through an inseparable mess of intermediate forms ( Santamaria 2002 ). The absence of protuberances on the perithecial body and of outgrowths near or at the perithecial apex is a first clue to classify this perhaps collective species.
