Etymology.

The genus name honors Lautaro (Leftraru), a renowned toqui (Mapuche military leader) who played a significant role in the Arauco War during the early stages of the Spanish conquest of what is now Chile. The name is derived from Mapudungun, with “ lef ” meaning “ fast ” and “ traru ” or “ bald traro. ” The feminine grammatical gender is used for the generic epithet.

Diagnosis.

Lautaria can be distinguished from all other genera of Triaenonychidae by the unique male genital morphology (Fig. 66 View Figure 66 , 67 View Figure 67 ). This includes a capsula externa with an apical region divided into two halves, forming a 90 ° angle in relation to the axis of the pars basalis. The external morphology exhibits striking similarities to the genus Chilenuncia , and other members of clade C.
