Ethiopia, Konso, Province Gamu Gofa , 5°16' N 37°23' E, 23.01.1960, 1 ♀ (W. Richter) ( SMNS) . Uganda: N, Madi Opei , 05.1951, 1 ♀ (van Someren) ( BMNH) . Kenya: Muguga , 04.1969, 2 ♀, 8.05.1969, 1 ♀ (C. F. Dewhurst) ( BMNH) . South Africa : Limpopo (as “ Transvaal ”): Wylies Poort , Zoutpansberg , 29.01.1955, 2 ♀ (“B. R. S. P. G. ”); KwaZulu-Natal: Ingwavuma District, 21.09.1961, 1 ♀ (T. Oatley) ( NMSA) .

D i a g n o s i s. C. loewi can be differentiated from other species of the genus from the combination of entirely yellow body, elongate pedicel, long, apically bluntly rounded and parallel-sided flagellomere 1, short and blunt, subshining ocellar triangle with 2 ocellar setae, parafacial narrower than flagellomere 1; prosternum bare, proepisternum with 2–3 setae; scapular seta twice as long as setulae; presutural supra-alar seta lacking; scutellum with 4 setae, short setulose; wing slightly darkened along anterior margin and crossvein dm-cu or entirely hyaline; vein R 2+3 with very short or without stump vein; femora ventrally short setose, with subbasal ventral (longest) seta as long as femur width; apicoventral setae short, spine-like; female mid coxa with 2 thickened setae laterally and row of 8–10 moderately short and thin black cilia medioventrally; hind coxa with slightly protruding antero-ventral surface covered with very thin and usually poorly visible setulae; oviscape long and narrow, 1.1–1.3 times as long as abdominal tergites combined, at its apical aperture with short convex, short medioventral and mediodorsal lobes and numerous setae not arranged into clear sensillar brushes or combs; aculeus ( fig. 16 , 4 ) short, as long as oviscape width apically ( fig. 16 , 1–3 , arrow).

It shares narrow parafacial, shape of antenna, long scapular seta, lacking presutural supra-alar seta, 4 scutellar setae and very long and narrow oviscape with C. gracilis and C. caudata , differing from them by less setulose mid coxa (in C. gracilis setae of the medioventral row strong, subequal to lateral setae, in C. caudata with thick brush of setulae) and hind coxa (in C. gracilis with sparse tuft of thickened setae, in C. caudata with thick brush of setulae wider than on mid coxa); in addition, C. caudata differs by strongly curved antero-ventrally and very long aculeus 1.4–1.7× as long as abdominal tergites combined.

R e m a r k. Hendel (1908) described Hypotyphla loewi as the species that has a very short, stick-like arista (which was originally proposed by Loew as the key character for Hypotyphla ); detailed microscopic study of the holotype H. loewi shows that its short arista ( fig. 15 , 5 ) is the result of clipping it in a live specimen, and the holotype otherwise shows no differences from other specimens from South Africa listed above in the material. Specimens from Central Africa show some variability (costal margin and crossvein dm-cu slightly brownish, vein R 2+3 with very short stump vein in 20 % of specimens), but I consider them all, including the holotype of Prohypotyphla (Hypotyphlina) saegeri to be conspecific. I therefore synonymize the latter species with H. loewi .

The nominal genus Hypotyphla Loew, 1873 syn. n. is considered a part of Campylocera and is synonymized with the latter.
