Diagnosis
Body dark-brown, antennae, mouthparts and legs red-brown. Spanglerelmis xiririca Polizei & Bispo gen. et sp. nov. can be easily differentiated from S. timburi Polizei & Bispo gen. et sp. nov. and S. femoralis by the profemora not swollen; hypomeron with a belt of tomentum near the suture; disc of abdominal ventrite 1 with a pair of carinae. While in S. timburi and S. femoralis the profemora is swollen; there is no tomentum on the suture on hypomeron; and absence of carina on disc of the abdominal ventrite 1. Moreover, the male genitalia can be differentiated by the phallobase 2.5× as long as penis (1.5× in S. timburi and 2× in S. femoralis ) and the penis with long setae on apex.
Etymology
The specific epithet xiririca refers to the oldest name for Eldorado county, the region where specimens of the new species were collected; it is an indigenous word (Tupi origin) meaning “running water”.
Type locality
Eldorado, São Paulo State, Brazil.
