Nothrus monodactylus

Nothrus monodactylus (Berlese, 1910) (non Michael, 1888)

Angelia anauniensis var. monodactyla Berlese , 1910b, p. 381.

Nothrus monodactylus , Jacot, 1937a, p. 354.

In the original diagnosis of the " variety " the monodactylous legs and the measurements (0.820 X 0.420 mm, posterior notogastral hairs probably included) are mentioned only. Jacot gave the present combination of names to the species and supposed (without having seen the species) that it is closely related to, or even synonymous with Nothrus terminalis carolinae Jacot (1937a, p. 354). The name A. anauniensis var. monodactylus points, however, to Nothrus silvestris .

In the Berlese Collection three types are present (nos. 121/36, 37, 38); they originate from Columbia, Missouri (U.S.A.). The material is damaged; h2 is lacking in all specimens. The length is 0.770-0.785, the breadth 0.400 mm; the length of the notogastral hairs ps1 is only 0.065 mm.

The species apears indeed to be related to Nothrus silvestris , although the bad condition of the specimens does not allow of a definite conclusion. I remark that Nothrus monodactylus (Berlese) and Malaconothrus monodactylus (Michael) are secondary homonyms.
