Index Fungorum number: IF551324; Facesoffungi number: FoF00977
Etymology – named after the type locality.
Holotype – BBH 18836
Parasitic in arthropods (Orthoptera, Gryllacrididae). Sexual morph: Stromata on body and leg joints of adult Orthoptera several, scattered, simple or branched, cylindrical to enlarged at the apices, yellowish cream, 1–3 mm long, with perithecia in small clusters (20–30) at the apices. Perithecia narrowly ovoid with acute apices, 650– 710×280–320 μm, superficial and crowded at the apex. Asci cylindrical, 370–450×5 μm, ascus caps 2.5 μm. Ascospores filiform, breaking into 32 part spores, 5–10× 1 μm. Some of the specimens are accompanied with the Beauveria asexual morph. Asexual morph: Synnemata arescattered on the body and legs of the host, cream to yellowish brown, smooth-walled, 2–6 mm in length, the upper portion mealy with oblong-ellipsoid conidia, some concave to one side and flattened or convex to the other (2–4×1.2−1.5 μm), white; conidiogenous cells round or flask-shaped, producing conidia sympodially on divergent denticles, in whorls of two or more or singly, scattered along the hypha.

Culture characters: Colonies on PDA are relatively fast growing, reaching 10 mm diam. after 14 days at 25 °C; circular, dense, at first white and floccose, becoming cream to yellow cream in the center with age; conidiation starts as early as 12 h after inoculation. Conidiophores arise from the agar, white, smooth-walled, conidiogenous structures up to 12.5 μm long, cylindrical or narrowing at the tip producing ellipsoidal to cylindrical conidia (3.5−6×1.5−2 μm) with rounded ends.
