Type species: Labronema mauritiense Williams, 1958 = Talanema mauritiense (Williams, 1959) Andrássy, 1991

The genus resembles both Labronema Thorne, 1939 and Takamangai Yeates, 1967 but differs from them in some definitive characters.  It differs from Labronema in having a transverse vulva, subdigitate tail and non-contiguous supplements, from Takamangai in having a double guiding ring, a subdigitate tail and higher number of supplements, from both of them in position of the hindmost supplement(s).
Soil nematodes distributed in Europe (1 species), Asia (4 species), Africa (2 species), North America (1 species) and South America (1 species).

"Tala" is composed of the first letters of Takamangai and Labronema, respectively.
