Etymology.

The generic epithet Nerudiella honors renowned Chilean poet and politician Pablo Neruda (1904–1973). Feminine grammatical gender.

Diagnosis.

Nerudiella species can be easily distinguished from other genera of Triaenonychidae by several notable characteristics. These include a relatively low to medium ocularium, which lacks an interocular apophysis or possesses a reduced apophysis (similar to that of the New Zealand Nuncia ); a pedipalpal femora typically slightly curved; and presence of a subtle sexual dimorphism. The most salient feature is the male genitalia with a distinctive dorsolateral plate that originates from the genitalia’s pars basalis and extends onto the pars distalis. This plate appears wide in its lateral portion but small in dorsal view. These unique genital structures serve as reliable markers for the identification of Nerudiella species.
