MALACONOTHRIDAE Berlese, 1916
Berlese (1896b, pp. 26-27) classified Nothrus monodactylus Michael (1888, p. 528, pl. 45 figs. 10-14) as Angelia monodactyla with the Nothridae 1). Afterwards (Berlese, 1913a) the genus Malaconothrus Berlese, 1904 (to which monodactylus belongs) was classified in a tribe ( Michaeliini) of this family. Finally, Berlese (1916a, pp. 175, 176) created a separate family Malaconothridae, consisting of the tribes Malaconothrini and Lohmannini . At present the genera Malaconothrus Berlese (1904) and Trimalaconothrus Berlese (1916) are the only representatives of the family; Mucronothrus Trägardh (1931) is according to Hammer (1958, p. 25) related to Trhypochthoniellus .
1) Berlese (1896b) records A. monodactyla from England only; possibly he had not seen the species.
