Genus Pygmaeodrilus Michaelsen, 1890

Pygmaeodrilus arausionensis Michaelsen, 1910 a: 114

Described from Bothaville, FS, RSA. The type depository is unknown; however, it might be housed in ZMUH. Known from Namibia (Grootfontain) and a few sites in RSA, where recorded only from the type locality and few sites in the same province: at Vaal Dam catchments at Kalkspruit , Grootvlei coal mine, and the Sabie River , Lover Sabie Rest Camp in KNP ( LP) ( Jamieson 1967). One of the smallest megadriles, being 25 to 40 mm in length and 1.5–1.6 mm in diameter. Its indigenous status is not confirmed. It is rather expected that this species is indigenous to south-western Africa, and to southern African continent is transported naturally by rivers .
