Diagnosis. Adult males of Nannaria piccoliasp. nov. are distinct from other Nannariaand the sympatric N. shenandoa, based on the following combination of characters: Gonopods.Gonopodal acropodite gradually curving medially before apex, not straight as in N. shenandoa. Distal zone short, bent medially forming 130° angle with acropodite (Fig. 17). Telopodite basal zone> 1/3 length of acropodite, not <1/3 as in N. fowleriand N. shenandoa. Tip and distal zone simple, rectangular, blunt, <1/8 length of acropodite, not large, curving with flange as in N. shenandoa. Prefemoral process short, laterally curved, arising dorsomedially from prefemoral spine, not long, serpentine, paralleling curve of acropodite as in N. fowleri, or crossing over acropodite as in N. shenandoa. Space between prefemoral process and acropodite wider than telopodite basal zone, not thinner as in N. fowleri. Prefemur with stout, tooth-like prefemoral spine (Fig. 17C, red arrow). Color.Tergites with either orange or white paranotal spots (Fig. 18A, B) and occasionally orange paranotal spots with orange stripes (Fig. 18 C). Brown to black background. Dorsum of collum smooth with either orange or white margin, depending on color morph. Figure 17.

Scale bar: 4.0 mm.
Measurements. ♂ holotype (VTEC, MPE03809): BL = 26.4, CW = 3.9, IW = 2.4, ISW = 0.8, B11W = 5.0, B11H = 2.9; ♀ paratype (VTEC, MPE03811): BL = 36.5, CW = 4.3, IW = 2.7, ISW = 0.9, B11W = 5.5, B11H = 4.0
Variation. No known variation.
Distribution. Known from a small area in western Virginia (Virginia: Allegany and Rockbridge counties, Suppl. material 7; Fig. 126). Distribution area: 35 km2; status: MRE.
Ecology. Individuals of Nannaria piccoliasp. nov. have been collected from mesic deciduous forests dominated by oak, maple, and hickory, typically found under leaf litter on hillsides.
Etymology. Named as a gesture of goodwill to the community of lichen specialists, in honor of the lichen species Piccolia nannaria(Tuck.) Lendemer & Beeching. The specific epithet is a noun in apposition.
Type locality. United States, Virginia, Rockbridge County, 1.5 air miles NW of Collierstown, Lake Robertson Recreation Area, Mountain Trail, hillside near Hawks Creek stream crossing, 37.8065°N, - 79.6152°W.
