Ten New Species of Cave Spiders with Marshal Hedin

Meet Dr. Marshal Hedin.

He’s an arachnologist fascinated with Nesticidae, a group of cave-dwelling spiders found in the southern Appalachian mountains, an area of tremendous beauty and biodiversity. In this interview he describes the joy of discoveries of new and interesting species, the struggles of collecting in rock piles and other dangerous terrain, as well as a few adventures along the way.

What can we learn from Nesticus? Marshal says: “I just think generally if you live in some hollow or some mountain in southern Appalachia and you happen to have some Nesticus that’s only found in that mountain you might find that interesting and unique…a sense of place, you know? That’s your little cave spider.”

Marshal Hedin’s paper “New species in old mountains: integrative taxonomy reveals ten new species and extensive short-range endemism in Nesticus spiders (Araneae, Nesticidae) from the southern Appalachian Mountains” is in the February 3rd, 2023, edition of Zookeys.

New Species: Nesticus binfordae, Nesticus bondi, Nesticus canei, Nesticus cherokeensis, Nesticus dellingeri, Nesticus dykemanae, Nesticus jemisinae, Nesticus lowderi, Nesticus roanensis, and Nesticus templetoni
