Laboulbenia cf. schizogenii Thaxter, Proceedings of the American Academy of Arts and Sciences 27: 43, 1891 ( Figure 5a )

Known distribution. This species was reported only from the American continent ( Brazil, Ecuador, U.S.A.) on species of Schizogenius and Clivina ( Coleoptera , Carabidae ) ( Proaño Castro & Rossi 2008).

New record from Sierra Leone. Eastern Province, Gola Rainforest National Park near Lalehun, 4.I.1989, W. Rossi , on the posterior margin of left elytron of Clivina (Leucocara) cf. interstitialis Dejean.

Remarks. In the thalli from Sierra Leone the perithecium is free on its dorsal side for about half of its length, while the same is almost entirely joined to the cells of the receptacle in the American thalli ( Thaxter 1896, Plate XXI, Figs. 13 & 14; Proaño Castro & Rossi 2008, Fig. 9). More abundant material is needed for correctly interpreting the taxonomic value of this feature.
