New records: MONTANA: Granite Co., Welcome Creek, 46.5638°N, - 113.7044°W, elev. 1239 m., 2 October 2006, P. Hendricks, mm; Welcome Creek divide, 46.6438°N, - 113.6949°W, elev. 1553 m., 1 October 2006, P. Hendricks, mm .

Notes: The SEMs presented here compliment the drawings in Shear (1971). The two-branched gonopods ( Figs. 255, 256 ) are unique in that the anterior branches, which are set with tiny cuticular projections, seem to arise from the sternal part of the coxosternum, which can be seen in a posterior view ( Fig. 256 ) to be poorly sclerotized. The posterior gonopod coxites ( Fig. 257 ) have an anterior movable flagellum made up of several separate filaments.
