Another New Wolf Spider Spotted

by Eric Neubauer

There’s an unnamed wolf spider species in the remote areas of TX, NM,AZ, and probably northern Mexico, which people have infrequently observed for years.

In early October, I stopped at the Eaton Hill Nature Center and Preserve high on a limestone hill in Sonora, TX. I did some spotlighting for spiders (of course I did) and found the unnamed spider was present in significant numbers although all were still juveniles.

Fast forward to November 24. The weather forecast was good and I took a chance and drove out to Sonora. Some nature center board members and some 4-H kids with parents arrived to help as the sun set. I could argue they were essential to my success, since they found all the best spiders. On the other hand they distracted me from finding much myself. All’s well that ends well.

Years ago, I found that studying wolf spiders as populations in their habitat was the best way to figure out what kind they were. We found juveniles to young to sex, female and male subadults, and female and male adults.

The adult male was a real shock. Initially I thought it was another unknown species. When I got a better look later, I realized it was simply a male of the unnamed species, though quite different from the juveniles and females.

This species is informally known as the Big-eyed Hogna in arachnologist circles, for obvious reasons. Until now no one had connected the adult males with this species. Now any unidentified male observations on the internet have increased value because we know what they are. I already found two from New Mexico.
