Genetic information (Fig. 27). Karschiola holoclera belongs to the BIN URI: BOLD:AFF9085. The two sequenced specimens from the Uluguru Mountains, Tanzania, showed 0% intraspecific genetic divergence.

Distribution (Fig. 28). The type species of the genus is known to date only from the Usambara and Uluguru Mountains of the Eastern Arc Mountains in Tanzania. Despite there being only few records of this species, the single specimen from the Mbizi Mountains in the southern part of the Albertine Rift in Tanzania is treated with caution as it lies far from the main range of the species which seems to inhabit the forested lower slopes of the mountains in eastern Tanzania. Furthermore, there are several examples of mislabelled specimens in the Philippe Darge collection from Mbizi with their correct locality being Uluguru, and vice versa (pers. comm. H. Takano; Takano & Bashford in prep.). It is also interesting to note that in the original description of the genus, Gaede (1926) mentioned a male specimen he had seen from Lindi in south-eastern Tanzania, but this locality is also likely to be incorrect and probably refers to a specimen collected in Usambara (cf. Takano et al. 2021).
