Diagnosis
Adult males of Nannaria terricola are distinct from other Nannaria, the sympatric N. ohionis, and the nearby N. shenandoa, based on the following combination of characters: Gonopods. Gonopodal acropodite very slightly curving medially before apex, nearly straight, not strongly curving medially as in N. shenandoa, or obviously curving medially as in N. ohionis. Distal zone and tip short, simple, bent at 90° angle to acropodite and curving dorsally—not bending medially as in N. ohionis, or large, with flanges, curving posterolaterally as in N. shenandoa. Telopodite basal zone ca. 1/2 length of acropodite, not ca. 1/3 as in N. ohionis, or ca. 1/4 as in N. shenandoa. Telopodite basal zone with lateral bulge (Fig. 86A, red arrow), lacking in both N. ohionis and N. shenandoa. Prefemur with straight acicular prefemoral process, not curving laterally as in N. shenandoa. Prefemoral process arising from prefemur, not from top of prefemoral spine as in N. ohionis. Prefemoral spine reduced to small ridge, fused with prefemoral process (Fig. 86B, red triangle), not large, projecting, acicular as in N. ohionis. Color. Tergites with either white or pale orange paranotal spots (Fig. 87). Tan to dark brown background. Dorsum of collum smooth with either white or pale orange caudal margin, depending on color morph.
Measurements
♀ syntype (NMNH, #2269): BL = 21.7 CW = 3.1, IW = 1.8, ISW = 0.9, B11W = 4.0, B11H = 3.1.
Variation
No known variation.
Distribution
Known from throughout central and southern Ohio (Ohio: Adams, Butler, Harrison, Hocking, Logan, Preble, and Stark counties; Suppl. material 7; Fig. 127). Distribution area: 33,812 km2; status: WRE.
Ecology
Individuals of N. terricola have been collected from mesic hardwood forests composed of sycamore, maple, beech, cherry, hemlock, oak, birch, pawpaw, spicebush, and alder. They were often found under leaf litter and logs on hillsides, occasionally under 1–2 cm of dark soil.
Etymology
Williams and Hefner (1928)[6] gave no explanation for the name terricola in their description of the species, but it is assumed that it is derived from the Latin terricolus, terrestrial.
Type locality
United States, Ohio, Butler County, Oxford, Hueston’s Woods; [39.5800°N, -84.7600°W].
Notes
In the original publication, Williams and Hefner (1928[6]: 106, 107) did not designate type specimens, but mentioned that adults were collected, implying the existence of a type series. Upon investigation of the type material deposited at the NMNH we found that six female syntypes existed (NMNH #2269). Where the male specimen which Williams and Hefner (1928)[6] illustrated and described currently resides is unknown.
