Nannaria honeytreetrailensis sp. nov. Figs 102 , 103 Vernacular name: "The Honey Tree Trail Twisted-Claw Millipede"

Material examined.

Holotype: United States - Virginia • ♂; Lee County, Cumberland Gap National Historic Park, Honey Tree Trail , 0.2 km E junction with Gibson Gap Trail ; 36.6078°N, - 83.6322°W; 29 Sep. 2006; P. Marek leg.; VTEC MMC0334.

Diagnosis.

Adult males of Nannaria honeytreetrailensis sp. nov. are distinct from other Nannaria and the nearby N. scutellaria , based on the following combination of characters: Gonopods: Gonopodal acropodite gently curving medially throughout, not straight with 90° medial bend as in N. scutellaria . Tip blunt, with small, triangular lateral flange (Fig. 102A , red arrow), lacking triangular medial flange of N. daptria sp. nov. Acropodite swollen basal to apex (Fig. 102A , red triangle), lacking acicular medial flange of N. scutellaria . Prefemur with short, acuminate, ventrally curving prefemoral process, not long, medially curving as in N. daptria sp. nov., or laterally curving as in N. scutellaria . Prefemoral process arising dorsolaterally from prominent, blunt prefemoral spine, not claw-like, as in N. daptria sp. nov. Telopodite basal zone height> 1/3 length of acropodite, not <1/3 as in N. scutellaria . Color: Tergites with large, hot orange/pink paranotal spots (Fig. 103 ). Black background. Dorsum of collum smooth with hot orange/pink margin.

Measurements.

♂ holotype (VTEC, MMC0334): BL = 35.5, CW = 4.5, IW = 2.6, ISW = 0.9, B11W = 5.5, B11H = 3.8.

Variation.
