Laboulbenia imitans Thaxter, Proceedings of the American Academy of Arts and Sciences 35: 180, 1899 ( Figure 4g )

Known distribution. Known only from Madagascar, associated with various species of Eurydera and Paraeurydera ( Coleoptera , Carabidae ) ( Balazuc 1982).

New record from Sierra Leone. Southern Province, Tiwai Island, 23–25.X.1989, W. Rossi , on the pronotum of Thyreopterus sp.

Remarks. The thalli from Sierra Leone have a longer cell I and cell IV not distinctly bulging outwards, but these characteristics do not seem enough for separating them from the parasites described and illustrated by Thaxter (1908, Plate LIX, Figs. 25–26).
