Trimalaconothrus optatus (Berlese, 1908)

Malaconothrus optatus Berlese , 1908, p. 12; 1910, p. 223, pl. 19 fig. 46.

Berlese described (1908) and figured (1910) M. optatus as having two claws at each leg; probably the smaller median claw had been overlooked, for afterwards (Berlese, 1916b, p. 336) the species was added to Trimalaconothrus , characterized by tridaetylous legs.

The description is, however, insufficient and no specimens are present in the Berlese Collection, so that the identity of T. optatus is uncertain. The indication of the type locality ("Italia") is of no value.
