Type

Holotype ♂, Chile?, with not further information ( BMNH), examined.

Diagnosis

Differs from other Euathlus species by the presence of few labial cuspules (<20). Male differs from other species except E. atacama , sp. nov. by the tibial apophysis with convergent branches ( Figure 8A ). Differs from E. atacama by the non-curved metatarsus I, and palpal organ morphology with very flat prolateral keels and serrated PI ( Figure 8B,C ). Female differs from other species by the shape of the spermathecae (see Legendre and Calderón 1984, pl. 11–fig. 13) with shorter basis and the spheroid chamber directed to the epigastric furrow.

Remarks

The holotype male of Pa. pulcherrimaklaasi is not congeneric with the paratype female and is transferred to another genus (see misplaced species). The paratype female of Pa. pulcherrimaklaasi fits with the generic characters of Euathlus , with the same spermathecal morphology as E. truculentus . No other differences between both were provided in the original description and its location is unknown. The paratype female of Pa. pulcherrimaklaasi was misidentified and is here identified as E. truculentus .
