Diagnosis

Scape and pedicel light brown except proximal half of scape yellowish; anteromedian projection of the metanoto-propodeo-metapecto-mesopectal complex curved in lateral view with blunt and lighter end, extending to end of mesosoma; mesometapleural sulcus present. Male genitalia: harpe finger-shaped in ventral and dorsal view; harpe/gvc index 0.65; dorsomedial margins of harpes slightly converging and almost touching at distodorsal margin of gvc, dorsomedial margin of harpe slightly concave and diverging distolaterally from base to apex; apex oriented distolaterally; harpe with at least ten median setae; lateral margin of harpe straight; genitalia strongly sclerotized with strongest sclerotization at harpe and aedeagus + gonossiculus.

Etymology

The species is named after the daughter of the second author.

Remarks

Comparison with similar species

Ceraphron ellae sp. nov. can be distinguished from all other species by its quite distinctive and strongly sclerotized male genitalia with finger-shaped harpe, pointed apex of harpe and with at least ten median setae distributed along the apical two thirds of the median margin of the harpe.

Condition of type material

In the holotype, the head, mesosoma and metasoma are detached, thus the body length measurement is not precise, and the right antenna is missing. The left antenna is slightly deformed (e.g., F9) and the posterior half of the metasoma is deformed which can also lead to imprecise body length measurement. The left fore wing is detached and the left hind wing is glued to a card. Left fore and hind legs as well as the right middle leg are missing (except coxae).
