Abstract

A new fossil species, Protanthomyza grimaldiisp. nov. (Diptera, Anthomyzidae), is described from Baltic amber (Eocene, 48–34 Ma) based on two (male and female) inclusions. It is the ninth species of the †genus Protanthomyza Hennig, 1965 and †subfamily Protanthomyzinae Roháček, 1998. Adult morphology of P. grimaldiisp. nov. revealed that the rich chaetotaxy of the thoracic pleuron, two anal veins and presence of the anteroventral process of the epandrium are plausibly shared by all species of Protanthomyza. Relationships of the new species, which belongs to a group lacking the ctenidial spine on the fore femur, are discussed.
