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. ohionisand  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.   Figure 86.  Nannaria terricola♂ (VTEC, MPE02234) left gonopod Aanterior view; red arrow indicates basal zone lateral bulge Bmedial view; red triangle indicates reduced, ridge-like prefemoral spine Cposterior view.

Scale bars: 4.0 mm.  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. terricolahave 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)gave no explanation for the name terricolain 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'sWoods; [ 39.5800°N, - 84.7600°W].  Notes. In the original publication, Williams and Hefner (1928: 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)illustrated and described currently resides is unknown. 3071355561 2021-01-01 2021-12-31 2021-01-01 United States Butler County 39.58 Hueston's Woods 6 -84.76 Oxford 6 6 Ohio Syntypes 3071355664 MPE03714 2016-06-16 J.
