In the morning I was pleasantly surprised by Rodrigo on Facebook. In a comment he let me know that a species of short-tailed whipscorpion had been named after me back in 2019!
Etymology: The specific name is a patronym, honoring John Bokma, a naturalist and amateur arachnologist, who has discovered many new species of arachnids in the surroundings of Xalapa, and guided the authors to the type locality of this species.
The bridge mentioned is the Xalapa bridge which has a single pier that drops almost 90 meters to the floor of a deep canyon. It is there where this species of short-tailed whipscorpion can be found.
In a similar habitat, also a canyon, close to the town of Palmarejo; Veracruz, which is also a short distance from Xalapa, I have found short-tailed whipscorpions walking on the underside of large rocks after rolling those over.
Since this specimen was photographed in a very similar habitat I guess it's Nahual bokmai. Most likely it's impossible to tell this from the photo alone, which was made with a Canon A640 in macro mode.
Short-tailed whip scorpions are very tiny, just a few mm, and look to the untrained naked eye like ants; except they move in a different way.
