( Figs. 53–56 View FIGURES 53 – 56 )

Description. Male: Head: Eyes bare. Frons subshining black with very short frontal and interfrontal setulae. Orbital plate relatively broad, shining blue-black. Lunule with base colour orange, covered in intense silver pollinosity, face and parafacials more lightly silver pollinose. Anterior genal setulae in single row of 6 along mouth margin. Antennae black, 1st flagellomere length to depth ratio 1.8:1. Arista short plumose; ratio of plumosity at maximum extent to depth of 1st flagellomere 0.6:1.

Thorax: mesonotum rather dull emerald-green, sclerites with greenish reflections. Anepisternum with 1 anterodorsal seta and 2 posterior setae. Katepisternum with 1 seta, a scattering of short setae across remainder of sclerite. Scutellar disc shining slightly lighter green than mesonotum, on margin with one setula between lateral and apical setae, 0 between apical setae. Calypteres pale with whitish fringes. Wing clear with yellow veins, wing length 2.8 mm. Legs black, all tarsomeres yellow but becoming slightly infuscate apically.

Male terminalia: Epandrium; in lateral view 9th and 10th terga not completely fused, 9th tergite roughly triangular, attached to anterior surface of, and approximately on third as wide as, 10th tergite, 10th tergite 4x as wide as high. Cerci elongated, broad, laminate structures, lying posterior to epandrium. Fused for much of their length, maximum width at half way along their length then narrowing slightly to apex. Apex of each cercus square, medially with a small finer-like projection, longer setulae along lateral margins and mid-line. Surstyli very small and completely enclosed within shell of epandrium, a small rounded process with numerous apical setulae, attached to structures at base of cerci by a narrow tendon. Medial lobe of epandrium well developed and partly covered in small spicules. Phallus a simple U-shape with a small, narrow apical section.

Type material. Holotype ♂. CAMEROON; 20 Km E. of Sangmélima , 7.xi.1987, A. Freidberg. ( TAUI)

Paratypes; 20 Km E. of Sangmélima , 7.xi.1987. A. Freidberg . 1♂, (TAUI); Bambalang, off Rt. N11, 35Km E. Bamenda, 1200m, 18.xi.1987, F. Kaplan, 1♂. (TAUI)

Differential diagnosis. A species with large, broad cerci, relatively moderately sized surstyli and a welldeveloped spiculate medial lobe of the epandrium. It is however distinguished by its very simple phallus which may indicate some association with a species such as F. longiphallus sp. nov.

Etymology. The specific epithet refers to the site of capture of the Holotype.
