Scale 0.5 mm: 16, 21; scales 0.1 mm: remaining figures. Distribution. The species was described from Cathedral Peak and is surprisingly not distributed only in Cathedral Peak NR forests (Rainbow gorge, Oqualweni Fern forest), but also in forests in Royal Natal NR (Gudu forest, Devilʼs Hoek, Fig. 120 ). Bionomics. All specimens were collected in siftings of forest litter in patches of indigenous forests at the elevation of about 1500–1700 m a.s.l. ( Figs. 124–127 , the abundance of specimens per kg of sifted material: 1.0 in Gudu forest, 0.7 in Devilʼs Hoek, 2.3 in Oqualweni Fern forest and 0.9 in Rainbow gorge).
