Additionally, members of R. spock gen. et sp. nov. lack a dense tuft of black setae on the apical part of tibia. Etymology The specific name refers to the fictional character S’Chn T’Gai Spock, a Vulcan/Human hybrid from the Star Trek universe, who served aboard the starship USS Enterprise as the chief science officer, played in the original series by American actor Leonard Nimoy.
