Pretty cool, the newly described Phidippus pacosauritus was originally documented on iNaturalist several years ago in Paco’s Reserva de Flora y Fauna in Mexico! The two Pacos and arachnologist Diego Barrales are big iNat users, and they’re all acknowledged in the paper, which can be found here.
From David Hill’s post in the Jumping Spider Biology Facebook group:
The only new species of Phidippus to be described since the revision of the genus by G. B. Edwards in 2004: Phidippus pacosauritus Edwards 2020. This spider is only known from a single nature reserve in Sinaloa, Mexico. Its existence was documented on iNaturalist in 2015, but it was not collected and named until recently after it was found by Colin Hutton. P. pacosauritus is a close relative of P. cruentus and P. arizonensis, and like those species males engage in a mating dance that includes pedipalp percussion that is audible to the human ear. The species is named after the two “Pacos” who operate the nature reserve, and “auritus” which is Latin for “long eared.”
I visited the reserve last year and interviewed these three awesome naturalists about the reserve and about iNat:
