Diagnosis
Scape longer than F1 to F3 combined; preoccipital carina distinct; OOL:LOL 1.45; OOL 1.60 × lateral ocellus diameter; anteromedian projection of the metanoto-propodeo-metapecto-mesopectal complex curved in lateral view with blunt, lighter and bifurcated end, exceeding end of mesosoma. Male genitalia: harpe trapezoidal in ventral and dorsal view; harpe/gvc index 0.60; dorsomedial margins of harpes not touching at distodorsal margin of gvc, dorsomedial margin of harpe straight and virtually parallel to other harpe in basal third, straight and diverging distolaterally with small indentations in apical two thirds, apex of harpe slightly rounded; longest apical setae as long as harpe; genitalia weakly sclerotized with weakest sclerotization at harpe; gvc width equal to distal gvc width.
Etymology
The species is named after the DJ and graduated ecologist Dominik Eulberg. He combines the great art of nature with his musical art and emotions, and creates an acoustic image of it. His music is regularly part of the first author’s playlist.

Remarks
Comparison with similar species
Ceraphron eulbergi sp. nov. can be distinguished from C. longisetae sp. nov. by the different setal arrangement on the harpes ( C. eulbergi has distinctly shorter lateral setae and longer apical setae than C. longisetae ), the shorter aedeagus + gonossiculus in C. eulbergi and the different harpe/gvc index (0.60 in C. eulbergi and 0.39 in C. longisetae ).
Condition of type material
In the holotype, the left hind wing and right hind leg (except coxa) are detached. The posterior end of the metasoma is slightly deformed, thus the body length measurement is not precise.
