Remarks.

See also remarks on Atrichotoxon and Udzungwalimax gen. n. below. The schematic of the structure of the genitalia of this genus (Figs 61-62) can be contrasted with those in Van Goethem (1977: 28). The monotypic Phaneroporus Simroth, 1888 from the coasts of Lake Tanganyika (south-western Tanzania and northern Zambia) is similar to Tanzalimax gen. n. and Udzungwalimax gen. n. in some respects, but differs in its massively enlarged penis and penial stylet ( Van Goethem 1977).
