Type deposition.
Holotype (♀), allotype (♂), and some paratypes (2 ♀; 2 ♂) deposited in the CNC; other paratypes (2 ♀; 1 ♂) deposited in the ACUA.
Diagnosis.
Torrenticola folkertsae are similar to other members of the Partial 2-Plate Group ( T. magnexa , T. priapus , and T. pulchra ) in having anterio-lateral platelets partially fused to the dorsal plate and being distributed in the east. T. folkertsae can be differentiated from T. magnexa and T. pulchra by having more elongate pedipalpal tibiae (length/width = 4.05-4.83 in T. folkertsae , 2.61-4.00 in others) and by dorsal coloration and pattern. T. folkertsae can be differentiated from T. priapus by having more elongate pedipalpal tibiae (length/width ♀ = 4.5-4.83 in T. folkertsae , 3.9-4.22 in T. priapus ♂ = 4.05-4.33 in T. folkertsae , 3.5-3.78 in T. priapus ) and a less elongate rostrum (length/width = 2.55-3.00 in T. folkertsae , 3.17-3.39 in T. priapus ).

Etymology.
Specific epithet ( folkertsae ) named in honor of Debbie Folkerts, professor of biology at Auburn University, who, together with her late husband George Folkerts, were instrumental to JRF in channeling his passion for natural history and teaching into a career path.
Distribution.
New Hampshire (Figure 81).
Remarks.
Unfortunately, we were unable to acquire fresh material of Torrenticola folkertsae and therefore this species is not included in our phylogenetic analyses. However, we were able to examine morphology with material preserved in GAW. The overall similarity, distribution, and partial fusion of the dorso-lateral platelets to the dorsal plate, are consistent with placing this species in the Rusetria Complex and the Partial 2-Plate Identification Group.
