Material examined.

Holotype: United States - North Carolina • ♂; Rutherford County, Rutherfordton , Bus. 74, 0.2 W Byp. 74; [35.3108°N, - 81.9303°W]; 15 Oct. 1973; R. M. Shelley leg.; NMNH USNMENT 01491821. For detailed collection data see Suppl. material 7. GoogleMaps  

Diagnosis.

Adult males of Nannaria rutherfordensis   are distinct from other Nannaria   and the nearby N. minor   based on the following combination of characters: Gonopods. Gonopodal acropodite simple, gently curving medially with extremely short, blunt distal zone, not with small, tooth-like medial flange near apex as in N. minor   . Prefemur with long, thin, medially curving prefemoral process, not acicular slightly curving laterally as in N. minor   . Prefemoral process arising from sharp, projected prefemoral spine (Fig. 111A View Figure 111 , red arrow), not from small prefemoral spine which curves cephalically as in N. minor   . Telopodite basal zone height < 1/2 length of acropodite. Color. Shelley (1975) described N. rutherfordensis   as having white paranota with a concolorous stripe along the anterior edge of the collum.

Measurements.

♂ holotype ( NMNH, USNMENT 01491821): BL = 28.0, CW = 3.2, IW = 2.2, ISW = 0.9, B11W = 4.3, B11H = 2.8.

Variation.

No known variation.

Distribution.

Known only from the type locality (North Carolina: Rutherford County, Suppl. material 7, Fig. 126 View Figure 126 ). Distribution area: N/A; status: MRE.

Ecology.

Shelley (1975, pp. 186) notes that the holotype was found under leaves by the side of a log in an "urban patch of hardwoods, a few feet from the pavement..." The authors JCM and DAH were unable to recollect N. rutherfordensis   on multiple trips to the type locality and surrounding area. The type locality had unfortunately recently been cleared for development and was found dry and lacking vegetation on each visit. The authors infer this species may be locally extirpated.

Etymology.

Shelley (1975) provides no etymology for his naming in his description of the species; however, it is reasonable to assume that N. rutherfordensis   is named after its type locality.

Note on clade membership.

No specimens of Nannaria rutherfordensis   were collected for this study. While it shares the gonopodal character of a prefemoral process that parallels the curved acropodite with N. kassoni   sp. nov. ( Nannaria minor   clade), this character is also found in N. fowleri   ( Nannaria fowleri   clade) and N. tasskelsoae   sp. nov. ( Nannaria tasskelsoae   clade), which are 352 km and 266 km north, respectively. In combination with the relative geographic isolation of the species, being the most southern species in North Carolina, clade membership is uncertain.

Type locality.

United States, North Carolina, Rutherford County, Rutherfordton, Bus. 74, 0.2 W Byp. 74; [35.3108°N, - 81.9303°W].

Notes.

In the original publication, Shelley (1975: 184) designates a male holotype ( NCSM 2053) which he collected on October 15, 1973. Interestingly, despite the type being deposited by Shelley at the NCSM, at some point before the writing of Hoffman’s (1999) checklist the specimen was moved to the NMNH and relabeled with the code USNMENT 01491821 by an unknown party.
