Othelosoma joburgi, the sickgreen flatworm, is a species of land planarian belonging to the subfamily Microplaninae. It is native to South Africa.
Othelosoma joburgi was described in 2004 by H. D. Jones of the University of Manchester, from type specimens found in Roodepoort, South Africa. The specific epithet is derived from Jo'burg, a colloquial name for Johannesburg and by extension the City of Johannesburg Metropolitan Municipality, of which Roodepoort is part of.
Othelosoma joburgi, from type specimens, can range from generally 6âÂÂ15 mm long and 1âÂÂ3 mm wide in size. The defining feature of Othelosoma joburgi is its "sick-green" color, which is nearly uniform all across the dorsal side of the body. The ventral side is white in color with no visible markings; two small eyes are on the anterior ventral side.
