description: Pyrgotomyia stuckenbergi sp. n.   Figs 5, 9, 15, 19, 38–40, 45, 53  
Etymology: Named for Brian Stuckenberg, in recognition of his great contribution to the study of Afrotropical Diptera.  
Description:  
 Female (Fig. 53). Generally similar to P. callosa, differing as follows.   
 Head: Length:height:width = 1.0:0.9:1.1; pale orange-yellow, except frons broadly brown, occiput with brown transverse mark in its dorsal portion and flagellomere 1 at apex brown. Frons subshining brown (only anterior margin, narrow median vitta, vertical plates and area corresponding to ocellar triangle yellow), 2.7× as long as wide in its narrowest part; with 1 short proclinate orbital seta and 8–12 setulae at each side 1–1.5× as long as orbital seta, forming 2 irregular transverse rows on its anterior portion. Parafacial and subocular sclerite entirely shining yellow, without brown areas. Face twice as high as wide; supraclypeal sclerite (Fig. 5) 0.8× as high as wide. Eye 1.24× as high as long and 4.5× as high as gena. Ocellar triangle not defined, ocellar seta either broken off or lacking; postocellar seta present, 0.25× as long as medial vertical seta; lateral vertical seta absent.Antenna with flagellomere 1 apically blunt, brown in apical one-third.   
 Thorax: Shining orange-yellow, mesonotum (Fig. 9) with pair of reddish brown vittae on both presutural and postsutural part of scutum lateral to dorsocentral setae; anepisternum with wide brownish yellow vertical spot; postpronotal lobe pale brownish; katatergite, anatergite, mediotergite and postscutellum brown; setae and setulae black or brown. Postpronotal seta present on left side only. One strong presutural (scapular) dorsocentral and one postsutural dorsocentral seta slightly posterior to level of supra-alar seta; other dorsocentral setulae fine, at most half as long as setae.   
 Wing (Fig. 15): Length 5.4 mm. Distance between wing base and apex of vein R 1 2.8 mm.   
 Abdomen: Abdominal sternites as in Fig.19; sternites 5 and 6 with anteromedial apodemes. Oviscape (Figs 38–40) moderately short and wide, 1.8 mm long, almost as long as thorax and preabdomen, conspicuously shorter than distance from wing base to vein R 1 apex and equal to distance from wing base to vein Sc apex; at apex about 0.8× as wide as at base; in profile curved dorsally, very slightly tapered to apex and without subapical callus.Aculeus (Fig.45) short triangular, not barbed subapically, 0.46 mm long and 1.1× as long as diameter of oviscape at apex. Spermathecae and ventral receptacle not found.   
 Male. Unknown.   
Holotype: ♀ (dissected) NIGERIA: “ Ile-Ife [7.4667°N 4.5667°E], Nigeria / 15Aug. 1970 / Col. T.J.Medler ” (USNM).  
Remarks: The variation in the body coloration and wing pattern can exist in larger series.
