Kainomyces alutellae Thaxter, Memoirs of the American Academy of Arts and Sciences 16: 365, 1931

= K. hyalinus Terada, Transactions of the Mycological Society of Japan 19: 56, 1978 syn. nov.

( Figures 4c and 4d )

Known distribution. Described on Eleusis alutella Fauvel from Cameroon ( Thaxter 1931) and subsequently recorded from Japan on E. coarctata Sharp ( Sugiyama 1973) .

New record from Sierra Leone. Eastern Province, Gola Rainforest National Park, near Lalehun, 20–23.XI.2015, W. Rossi , on various parts of the body of Eleusis sp.

Remarks. The receptacle and the appendage of the thalli from Sierra Leone can be almost completely hyaline ( Figure 4c ) or variably suffused with dark brown on the posterior margin ( Figure 4d ), which makes meaningless the differences between K. alutellae and K. hyalinus . The latter was described on Eleusis humilis Erichson from Taiwan.

The record of Kainomyces alutellae from Japan needs confirmation: in the picture given by Sugiyama (1973, Plate 18, Fig.4 ) the cells of the receptacle seem to be divided by vertical septa, as in K. isomali ; the same are undivided in K. alutellae .

Laboulbenia bolamensis Spegazzini, Anales del Museo Nacional de Historia Natural de Buenos Aires 26: 501, 1915.

Known distribution. Reported from Guinea-Bissau (type), India, Indonesia, Madagascar and Senegal on various species of Styphlomerus ( Coleoptera , Carabidae ) ( Balazuc 1982).

New record from Sierra Leone. Northern Province, near Bumbuna, 14–15.VI.1987, W. Rossi , on Styphlomerus sp.

Remarks. The finding of this parasite in Sierra Leone is not surprising because it was described from the nearby Guinea-Bissau on a similar host insect.
