description: Pyrgotomyia terebrans sp. n.   Figs 7, 13, 31–33, 43, 50  
 Etymology: From Latin terebrans (drilling, piercing), referring to its long oviscape.   
Description:  
 Female. Long-bodied species (Fig. 50), in general features, as described for P. callosa sp. n. and P. ciliata.   
 Head (holotype somewhat shrivelled, no reliable measurements of length:height:width available, but looking conspicuously longer than high): pale orange-yellow, except flagellomere 1 brown in apical half. Frons subshining yellow, without brown areas, twice as long as wide in its narrowest part; all large setae broken off, except 8 or 9 irregular setulae on its anterior portion. Parafacial and subocular sclerite entirely shining yellow, without brown areas. Face deeply concave, 1.75× as high as wide, shining; supraclypeal sclerite (Fig. 7) poorly separated from face, twice as high as wide (in its dorsalmost part). Eye 1.3× as high as long and 3.2× as high as gena. Antenna elongate, pedicel and flagellomere 1 combined about half as long as face; flagellomere 1 slightly shorter than pedicel and 1.2× as long as palp.   
 Thorax: Shining yellow, without brown areas.Almost all setae except 1 short presutural dorsocentral (scapular) and 1 setula-like prescutellar postsutural dorsocentral setae broken off in the holotype; 1 moderately long supra-alar seta present.   
 Wing (Fig. 13): 6.7 mm long; with hyaline costal cell; pterostigma yellow; distance from wing base to apex of vein R 1 4 mm; vein R 2+ 3 in holotype with apically slightly bifurcated stump vein; vein R 4+5 setulose, but most setulae distally of r–m broken off; crossvein r–m not dark emarginated; wing in apical part with brown crossband, unbroken and narrowed through vein dm–cu to posterior margin and brown apical portion of r 1 cell; apices of cells r 2+3, r 4+5 and m hyaline, without conspicuous marginal darkening. Upper calypter long black ciliate, as in P. callosa sp. n.   
 Legs: Yellow, with dark yellow tarsi.   
 Abdomen (Figs 32, 33): Shining reddish brown, brownish setulose. Sternites short and fine setulose. Oviscape 4.6 mm long, 1.9× as long as thorax, about twice as long as preabdomen, conspicuously longer than distance from wing base to vein R 1 apex and equal to distance from wing base to vein dm–cu; ventrally in apical 0.95, dorsally in apical 0.8 short brownish setulose; subapically not swollen, about 0.3× as wide as at base and almost parallel-sided in apical 0.4. Apex of oviscape in profile very slightly curved dorsally, laterally and laterodorsally with fringe of long setulae 0.8× as long as oviscape diameter at apex. No trace of scleritized lobes at base of eversible membrane. Aculeus (Fig. 43) elongate, slightly barbed subapically, 0.48 mm long and 1.4× as long as diameter of oviscape at apex. Spermathecae and ventral receptacle not examined.   
 Male. Unknown.   
Holotype: ♀ IVORY COAST: “LAMTO (Toumodi) [6.5580°N 5.0177°W] / Côte d’Ivoire / Juill. Aout. 1968 / C. Girard Hl. ”, “ Pyrgotidae / L. Matile det.” (MNHN).  
Remarks: The new species is described based only on the holotype. The abdomen after maceration in potassium hydroxide was found to be full of mites, which had eaten its contents, possibly including the spermathecae.
