Abstract
Three new species of Rhizomyces Thaxt., parasitic on African stalk-eyed flies, are described. These are R. forcipatus W.Rossi & Feijen sp. nov., parasitic on various species of Centrioncus Speiser from Ivory Coast, Kenya and Malawi and Teloglabrus Feijen from South Africa; R. ramosus W.Rossi & Feijen sp. nov., parasitic on Diopsina nitida (Adams, 1903) from Uganda; R. tschirnhausii W.Rossi & Feijen sp. nov., parasitic on Diopsina africana (Shillito, 1940) from Uganda. All previous records of species of Rhizomyces are presented in tabulated form with updated host names. A key is presented to all species of Rhizomyces. The occurrence of Rhizomyces and other taxa of the Laboulbeniales Lindau in the genera of the Diopsidae Billberg is discussed.
Highlights
About 10% of the approximately 2100 described species of Laboulbeniales Lindau, parasitic fungi of arthropods, is associated with the Diptera Linnaeus, 1758
The thalli of the Laboulbeniales were removed from the hosts by means of an entomological pin (#3) and permanent slides were prepared following the method described by Rossi & Santamaría (2015), with the exception of a few old slides (HF in RMNH) in which Hoyer’s medium was used as mounting medium
Key to all the Rhizomyces It should be noted that R. cornutus Thaxt., R. cucullatus Thaxt. and R. gibbosus Thaxt. are very closely related and the distinguishing characters reported in the key are those given with the original descriptions (Thaxter 1901, 1918, 1931)
Summary
About 10% of the approximately 2100 described species of Laboulbeniales Lindau, parasitic fungi of arthropods, is associated with the Diptera Linnaeus, 1758. Rhizomyces is a relatively small genus with ten species described far, all of which are parasitic on Afrotropical Diopsidae (Thaxter 1931; Rossi 1990a). The records of these fungi are not numerous. From Sierra Leone (Rossi 1982) were reported as Diopsis thoracica Westwood, 1837 and Diopsis tenuipes Westwood, 1837, but were later identified by H.R. 4) The insect hosts of R. ctenophorus Thaxt. In the present paper three new species of Rhizomyces occurring on Afrotropical Diopsidae are described Two of these fungi display quite peculiar characteristics: one A key to all the species of Rhizomyces, including the new ones, is given
