Fulgenta excisa sp. nov. (Figs. 2, 4, 19–22) Description. Male: Head: Eyes bare. Frons subshining black, very slightly pollinose, orbital plates shining black, frontal and interfrontal setulae very short. Orbital plate shining black, bare apart from orbital seta. Lunule with base colour orange, covered in sparse silver pollinosity as are face and parafacials. Anterior genal setulae in a single row along mouth edge. Antennae entirely black, 1st flagellomere length to depth ratio 1.6:1. Arista yellow basally, very short plumose, ratio of plumosity at maximum extent to depth of 1st flagellomere 0.3:1. Thorax; mesonotum, thoracic sclerites and scutellar disc all shining bright emerald-green. Anepisternum with 1 anterodorsal seta and 2 posterior setae. Katepisternum with 1 strong seta, a weak seta lying anterior to it, otherwise sclerite with just a few short setulae. 1 seta on both proepimeron and proepisternum. Scutellum, on margin between lateral and apical setae, with 1 small setulae on each side, 0 between apical setae. Calypteres pale with whitish fringes. Wing very slightly fumose, wing length 2.8mm. Legs black, basal and second tarsomeres pale, apical tarsomeres darkened. Abdomen: tergites shining emerald green, tergite 5 with an apical semi-circular invagination, margin with 8 apical setulae longer than other setulae on abdomen. Male terminalia:;) Epandrium; in lateral view 9th and 10th terga not completely fused, 9th terga a rounded cone attached to anterior surface of, and half as wide as, 10th terga, 10th terga 4x as wide as high; cerci elongated laminate structures, lying posterior to epandrium. In the holotype the large cerci extend dorsally, but this most probably relates to the position in which the specimen dried. In posterior view surstyli relatively large and simple with a rounded apex, joined medially, a scattering of short setulae along medial margin and at apex. In posterior view cerci forming laminate processes, fused medially but separate on apical half and basal quarter. Relatively large and simple with a slightly irregular outer margin and rounded apex, a scattering of short setulae along medial margin and at apex. Surstyli enclosed within shell of epandrium, a simple rod-like structure with long ventrally directed setulae along margin. Phallus; sinuous, basiphallus C-shaped, rather broad, distiphallus thin and sinuous, with a pair of rounded leaf-like processes on medial margin. Type material. Holotype ♂ CAMEROON; Rt. N 9, 20 Km. E. of Sangmelima, 7.xi.1987, A. Freidberg. (TAUI). Paratypes: CAMEROON; Rt. N 9, 80 Km. SE. of Yaounde, 6.xi.1987, leg. A. Freidberg. 1♂, (TAUI). NIGERIA; Plateau State, Karra Falls, 60 Km SE of Jos, 5–7.xii.1987, F. Kaplan, 1♂, (TAUI). DEMOCRATIC REPUBLIC of the CONGO; Parc Nationale Garamba, Mt Tungu, Miss. H. de Saeger, 9.vi.1952. 1♂, (MRAC); Parc Nationale Garamba, Miss. H. de Saeger, 3.v.1952, 2♂; (MRAC). Differential diagnosis. Another species with large, relatively simple cerci and rudimentary surstyli. The phallus has a pair of medial processes in the shape of rounded lobes as in F. longicerca MacGowan but in that species the phallus is less angled with smaller medial lobes. Etymology. The specific epithet refers to the excised apex of the abdomen.
