Type material examined. Holotype Ô “// LESOTHO: Butha-Buthe: / Afriski Mountain Resort / 28°49’22.2”S, 28°43’41.0”E / 3–7.xii. 2021, 3032 m a.s.l. / Midgley, J.M. & Muller, B.S.” // “ Sweepnet / Drakensberg Afro- / alpine Heathland ” // “NMSA-Dip. 212862”; NMSA type no. 3237. 1Ô 7♀ Paratypes: same data as holotype (Ô: BMSA (D)129185; ♀: BMSA (D)130304, BMSA (D)130322, BMSA (D)129186, NMSA-Dip. 212863, NMSA-Dip. 212864, NMSA-Dip. 212865, NMSA-Dip. 212866); NMSA type no. 3237

Diagnosis. Males can easily be distinguished from other species within the globuliseta- group, and other nonglobular species by the seemingly unique apically globular seta on the antennal pedicel (Fig. 7) in combination with well-developed and normally appearing thoracic and leg setae and setulae. Females have the supramedian posterior seta on the mid tibia absent, and tergite 6 as two relatively slender plates ( Fig. 24 ), compared with females of C. flagelliseta (the only other known female in the group) that have the seta present, and tergite 6 as a broad, fused plate ( Fig. 26 ). Males and females with preapical dorsal and anterodorsal setae on hind tibia, unlike the other species in the group.
