Type material - The holotype of undeterminable gender is labelled ‘ HOLOTYPUS (red label with black submarginal border) / TYPE (red label with black submarginal border) / Congo belge: P. N. U.

The specimen is double mounted (minuten in block of foam), is in fairly good condition (antennae, meta legs, and terminal segments of abdomen broken), and is deposited in the MRAC .

21 paratypes (11^^ 6ơơ 4?) from the Upemba National Park are deposited in the ISNB. The following list will only provide the locality data, date of collection, and collector: 5^^ 3ơơ 2??

Two additional paratypes apparently belong not to E. festiva , but are species of Leptogaster .
