Diagnosis.
Adult males of Nannaria piccolia sp. nov. are distinct from other Nannaria and 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 View Figure 17 ). Telopodite basal zone> 1/3 length of acropodite, not <1/3 as in N. fowleri and 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 View Figure 17 , red arrow). Color. Tergites with either orange or white paranotal spots (Fig. 18A, B View Figure 18 ) and occasionally orange paranotal spots with orange stripes (Fig. 18 C View Figure 18 ). Brown to black background. Dorsum of collum smooth with either orange or white margin, depending on color morph.
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 View Figure 126 ). Distribution area: 35 km2; status: MRE.
Ecology.
Individuals of Nannaria piccolia sp. 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.
