CA7A1872FA78B91FFDB4FCBB3E93FA2B.taxon	description	Description SIZE. 6.2 - 7.5 mm, wing length 4.8 - 6.6 mm. HEAD. Pedicel and 1 st flagellomere not longer than ptilinal suture. Face (Fig. 4 A): antennal furrow without a dark spot; upper area with a dark marking, tending to an inverted V-shaped dark marking (in some specimens this extends down each side of carina and may be mistaken for facial spots). Frons: frontal setae 0, orbital seta 0. THORAX. Scutum (Fig. 4 B) predominantly fuscous, tending to red-brown antero-laterally; postpronotal lobe entirely pale, yellowish; notopleural callus pale posteriorly, anteriorly concolorous with scutum; notopleural xanthine probably isolated from notopleural callus but can appear almost joined (as in wedge form); lateral and medial postsutural vitta absent. Scutellum without any dark patterning (except for basal dark margin, which is very narrow). Anepisternum (Fig. 4 C) with a stripe from notopleural callus to (or almost to) katepisternum; stripe very broad (anteriorly extending almost to postpronotal lobe); extended onto katepisternum. Laterotergal xanthine confined to katatergite. THORACIC SETAE. Anterior notopleural seta present; anterior supra-alar seta present. WING (Fig. 4 E). Basal cell bc without microtrichia; cell c with an almost complete (> 90 %) covering of microtrichia; cell bm without microtrichia. Narrow subbasal raised section of cell br with extensive covering of microtrichia; partly bare in apical half. Crossvein R-M beyond middle of cell dm. Costal band complete; shallow, not or barely extending below vein R 2 + 3, except in basal section (before crossvein R-M) and at wing apex; expanded into a small spot at apex. Anal streak absent (but with a trace of colour confined to cell bcu). Cells bc and c coloured (not as deep as costal band). Without any crossbanding. LEGS. Forefemur pale, yellowish, sometimes indistinctly darkened apically; midfemur bicoloured (pale basal half to two-thirds, red-brown apically); hindfemur pale, yellow, rarely distinctly darkened apically. ABDOMEN. Predominantly fuscous; shape and patterning, see Fig. 4 D. Tergites I-V all fused. Male Tergite III with some very fine hairs (possible vestigial pecten); lacking hindtibia preapical “ pad ”. Basal costal sections without specialised setae. Female Aculeus pointed, similar to B. stylifer.	en	Meyer, Marc De, White, Ian M., F. M.

CA7A1872FA78B91FFDB4FCBB3E93FA2B.taxon	discussion	Remarks The new species is very similar to Dacus stylifer which is an East African species. It differs in the wing cell c having almost complete coverage of microtrichia in the males (50 % in male stylifer); the midfemur bicoloured (pale in typical stylifer); the notopleuron bicoloured and sutural xanthine distinct, unlike typical stylifer. Dacus goergeni sp. nov. is placed in the ill-defined subgenus Psilodacus, based upon a combination of characters, which typify the grouping, including the lack of facial spots: the dark, almost inverted V-shaped, dark marking at the top of the face; lack of anal streak and male pectin; it differs from most Psilodacus spp. in having anterior supra-alar setae. The type specimens were captured in the Guinean Forest Savannah Mosaic and the Eastern Guinean Forest ecoregions. Label information indicates that the specimens were collected in forested areas.	en	Meyer, Marc De, White, Ian M., F. M.

CA7A1872FA7AB91FFDE1F9EE3F86F8A7.taxon	discussion	Among the material examined was a male specimen collected at Ibadan, Nigeria (4 - 8 Dec. 2003, cue lure traps, leg. G. Goergen), in addition to the male specimen studied earlier (White & Goodger 2009). It shows some morphological deviation from the earlier collected specimen and from the type material as redescribed in White (2006): the xanthines (katatergite and anatergite) are fused, while in the typical D. pleuralis the xanthines are clearly separated. The anterior supra-alar seta is absent or vestigial while well developed in the typical D. pleuralis. These differences, however, appear to be intraspecific variation and do not warrant separate description.	en	Meyer, Marc De, White, Ian M., F. M.

CA7A1872FA7DB918FDC4FD0B3ED9FC6D.taxon	discussion	A male specimen from Sérou, Benin (Dec. 2005, leg. G. Goergen) differs from D. blepharogaster, as described by White (2006) in having some red pattern on the third abdominal tergite. However, since this species belongs to a group that needs proper revision (Dacus (Lophodacus) brevis group as defined by White 2006) and since only one specimen was found in the collections studied, it is not described as a separate species. As the previous species, this is also predominantly an East African species (Kenya, Eritrea and Ethiopia) but was not included in the richness analysis.	en	Meyer, Marc De, White, Ian M., F. M.

CA7A1872FA7DB918FDF5FEAE3F6AFD5E.taxon	discussion	Dacus mochii was described from Eritrea, but the type specimens were lost. White (2006) placed it in synonymy with D. annulatus Becker, based on the similarity of the original description. Subsequently, White & Goodger (2009) reported a specimen from Ethiopia, which was clearly not D. annulatus, but was a good match to the description of D. mochii, which they then removed from synonymy. Amongst the material examined here, there was a male specimen from Kloto, Togo (Mar. 2006, leg. G. Goergen), which is very similar to the D. mochii from Ethiopia, except that it has pallid face spots. Togo is a considerable westward expansion of the known distribution of a species otherwise known only from a restricted area of East Africa. Since it concerns a single specimen whose identity is uncertain, we excluded it from the richness analysis.	en	Meyer, Marc De, White, Ian M., F. M.
