Etymology: "This species is named for the inveterate invertebrate collector and arachnologist, Rick Vetter, who sent this and many other specimens for examination" (Brookhart & Cushing, 2008, p. 60).

Chelicerae Description: Chelicerae "similar to H. banksi with a short, small ventral concavity anteriorly. A highly visible ridge on the distal, ventral margin of fixed finger.
