Chumma sp.

Material examined.

South Africa; Northern Cape Province • 1 subadult ♂; Nigramoep Slow Living Guest Farm ; 29°31.460'S, 17°35.628'E; 840 m a. s. l.; 10 Jan. 2021; C. Haddad et al. leg.; leaf litter, west-facing slope; NCA 2021/652 .

Distribution.

Although this species is only known from a single subadult male, it is the first record from the Northern Cape Province, extending the range of the genus by more than 450 km northwards in the western extreme of its distribution (Fig. 4 ). This disjunct distribution of the genus suggests that it likely occurs in Fynbos and Succulent Karoo biotopes along the western interior of South Africa too. Its apparent absence here could be attributed to the historically poor sampling effort in this part of the country, whereas the southern and central parts of the country where most Chumma have been recorded (Figs 4 , 5 ) are comparatively well-sampled ( Dippenaar-Schoeman et al. 2023).
