Laboulbenia assingii W.Rossi & M.Leonardi , sp. nov.
( Fig. 1A View FIG )
Thallus compact, with very short receptacle and cell V not reaching cell III; inner appendage minute, bearing a single, terminal antheridium; outer appendage unbranched and unusually stout, its basal cell as broad as cell III.
ETYMOLOGY. — Named after the German entomologist Volker Assing, distinguished student of the Staphylinidae and collector of the new species.

DESCRIPTION
Thallus short and compact, colored dirty yellow with somewhat darker perithecium. Receptacle very short, broadly triangular, with cell I slightly longer than maximum width and cell II about as long, but much broader than the former, separated from cell III by a short, horizontal septum and from cell VI by a much longer, oblique and sometimes concave septum. Cell III quadrangular, slightly longer than broad. Cell IV similar to cell III, with a small and triangular cell V in its upper, inner angle. Insertion cell dark brown, relatively thin. Outer appendage simple and unusually stout, its basal cell as broad as cell III. Inner appendage consisting of a very small basal cell bearing a single flask-shaped antheridium. Perithecium ovoid, almost one half free from the receptacle, with a short, broad and blackened tip ending in an obliquely truncate and almost flattened apex distinctly directed outwards. Length from foot to perithecial tip 123-150 µm; perithecium 76-81 × 39-41 µm.
REMARKS
The very stocky habitus paired with the stout outer appendage makes this new species distinguishable at first sight. Laboulbenia assingii , sp. nov., is likely allied to L. kenyensis W.Rossi & Santam. parasitic on Mimogonus rossii Bordoni from Kenya, which also has a simple outer appendage and a single antheridium, but the latter species has a more slender appendage, elongate perithecium, much longer basal and suprabasal cells forming a geniculate receptacle, as well as other minor differences ( Rossi & Santamaría 2000).
