Adult males of Nannaria castra sp. nov. are distinct from other Nannaria and the nearby N. aenigma Means, Hennen & Marek in Means et al. 2021, based on the following combination of characters: Gonopods. Gonopodal acropodite relatively straight before curving medially at half-way point, not continually curving as in N. paupertas sp. nov. Distal zone curving dorsally, with tip directed caudally (Fig. 20B View Figure 20 )-not curving ventromedially with tip directed dorsomedially as in N. paupertas sp. nov., or tip directed medially as in N. aenigma . Acropodite tip with lateral flange (Fig. 20A View Figure 20 , red arrow). Acropodite with slight twist and swelling at midpoint (Fig. 20C View Figure 20 , red triangle), lacking medial flange of N. paupertas sp. nov., or lateral flange of N. aenigma . Telopodite basal zone thin, with slight lateral bulge, height subequal to 1/2 length of acropodite, not wide as in N. paupertas sp. nov., or > 1/6 length as in N. aenigma . Prefemur with dorsomedially curving prefemoral process (Fig. 20B View Figure 20 ), not ventromedially curving as in N. paupertas sp. nov., or straight as in N. aenigma . Prefemoral spine absent, not prominent, acicular as in N. paupertas sp. nov. Color. Tergites with orange paranotal spots (Fig. 21 View Figure 21 ). Black background. Dorsum of collum smooth with orange margin.
♂ holotype (VTEC, MPE03470): BL = 28.5, CW = 3.6, IW = 1.8, ISW = 0.7, B11W = 4.2, B11H = 2.5. ♀ paratype (VTEC, MPE03476): BL = 27.8, CW = 3.6, IW = 2.0, ISW = 0.9, B11W = 4.5, B11H = 3.2.
No known variation.
Known only from the type locality, Camp Creek State Park (West Virginia: Mercer County; Suppl. material 7; Fig. 126 View Figure 126 ). Distribution area: > 1 km2; status: MRE.
Individuals of N. castra sp. nov. were found in a mesic hardwood and rhododendron forest on top of hardpacked soil surrounding the entrance parking lot to Camp Creek State Park, and along the road leading towards the park campground. The majority of individuals were walking on top of the soil beneath leaf litter.
This species is named for its type locality. The specific name a noun in apposition from the Latin castra for ‘camp.’
