Euathlus condorito sp. nov.

( Figure 5 )

Types

Holotype ♂, Chile, Región Metropolitana Santiago, Farellones (33°22' S, 70°17' W), 2400 m above sea level, December 2005, Claudio Velosos leg. Paratype ♀, from the same locality of the holotype. Both types are deposited in the arachnological collection of the Museo de Zoología , Universidad de Concepción, Chile ( MZUC-UCCC 35891 ) .

Etymology

The specific epithet is a noun in apposition inspired by the main character of the most popular Chilean comic book of the same name, and one of the most acclaimed comics in Hispanoamerica. Condorito represents a man–condor, emblematic bird of the Andeans and Chile’ s national symbol, created in 1949 by Chilean cartoonist “Pepo”.

Diagnosis

Male differs from E. truculentus and E. atacama sp. nov. by the not convergent tibial apophysis branches ( Figure 5D ), and also from E. truculentus by the non-serrated PI, from E. manicata by the absence of accessory keels and from E. parvulus by the presence of an entire PI (not truncated). Female differs from other species by the shape of the spermathecae with a small sclerotized nodule on each receptacle ( Figure 5C ).
