( Figs. 5 , 48–52 ) Description. Male: Head : Eyes bare. Frons velvet black with very short frontal and interfrontal setulae. Orbital plate relatively broad, shining blue-black. Lunule covered in intense silver pollinosity, face and parafacials slightly silver pollinose. Anterior genal setulae in a single row along mouth margin. Antennae black, 1st flagellomere rather obscurely orange on basal medial third (this not so evident on the Paratypes ), length to depth ratio 1.6:1. Arista yellow basally, short plumose; ratio of plumosity at maximum extent to depth of 1st flagellomere 0.6:1. Thorax : mesonotum shining emerald-green, anepisternum and katepisternum 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 emerald-green as mesonotum, on margin between lateral and apical setae with one short setula, 0 between apical setae. Calypteres pale yellowish with whitish fringes. Wing slightly yellowish with yellow-brown veins, wing length 2.6 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 terga a broad rounded lobe attached dorsally to anterior surface of, and approximately one third as wide as, 10th terga. 10th terga 3x as wide as high. Cerci elongated laminate structures, lying posterior to epandrium, clearly separated, each with a rather square basal section, narrowing at midpoint to a shallowly bi-lobate apex, covered in fine setulae. Surstyli a small rounded structure with apical setulae, completely enclosed within shell of epandrium and attached to structures at base of cerci by a narrow tendon. Phallus; basiphallus cuboidal with two anteriorly projecting, serrated basal processes, two smaller lateral processes also with serrated apices. Distiphallus arising centrally from basiphallus, forming a slender curved tube. Type material. Holotype ♂ . DEMOCRATIC REPUBLIC of the CONGO ; Parc Nationale Garamba, Mt Tungu, Miss. H. de Saeger, 9.vi.1952 , ( MRAC ). Paratypes; Parc Nationale Garamba, Miss. H. de Saeger, 18.xii.1951 , 1♂; 3.v.1952 1♂; 18.viii.1952 , 1♂, (MRAC) Differential diagnosis. This is the third of the group of species with a cuboidal basiphallus, the others being F. complexa sp. nov and F. plumosa sp. nov. It is has the longest cerci of these species and the surstylus is similarly reasonably well developed. It is however easily distinguished by the distinct cerci and phallus. Etymology. The specific epithet refers to the captor of the Holotype .
