Zuellig, 49&amp;male;, 30&amp;female; (CSUC). <b>Virginia</b>: Montgomery Co., Tom’s Creek, Rt 655, 18 February 1981, B.C. Kondratieff, 2&amp;male; (BPS). Wythe Co., East Fork Stony Fork Creek, Hwy 52, 28 December 1978 - 29 January 1979, R.F. Kirchner, 18&amp;male; (BPS). <b>Male epiproct.</b> Apical segment of upper limb ca. 340- 400 μm long, armed on apical ca. 140-165 μm with dense patch of wave-like spikes (Figs. 55-57); apical segment ca. 110-150 μm wide at base, tapered to a broadly rounded tip. Basal segment of upper limb ca. 290-320 μm long and ca. 80-120 μm wide at midlength; basal segment with a moderately broad, shallow groove extending from base to apical segment base. Greatest width of lower limb ca. 173- 200 μm, and bearing a sparse, irregular row of marginal setae in apical half of limb (Fig. 57). <b>Male tergal process.</b> Prominent raised structures on abdominal terga 7 and 8 (Figs. 58-60). Trilobed process on tergum 8 ca. 190-220 μm wide, and bearing a broad, shallow median notch interrupted by a median projection. Tergum 7 process much lower and not distinctly trilobed; both tergal processes covered on dorsum with scale-like structures; tergum 8 process with a deep, transverse groove on anterior face. In lateral aspect, lobes of 8 th tergal process appear thin and bent forward (Fig. 60).
