Pronotum with sides and base hemispherically rounded, transverse, widest anteriorly, distinctly constricted in basal half, surface near anterior angles weakly explanate disc punctation two sizes, fine punctures evenly distributed, dense, coarse punctures roughly 5× larger than fine punctures evenly widely scattered lateral margins lacking setal fringe, evenly arcuate from anterior angles to middle of base, posterior angles obliterated basal margin evenly rounded, with marginal groove and bead at middle fine, reduced to lacking on either side. Epipharynx with apical margin sinuate, tylus projecting chaetopedia few and stout epitorma broad (Fig. Head with clypeus broad, distance between anterior most point of clypeal margin roughly equal to the distance from angle to frontoclypeal suture clypeal anterior margin with spiniform tooth each side of middle, tooth situated medially of most anterior part of clypeal margin, margin weakly crenulate near teeth and with short setal fringe, distinct in dorsal view clypeal surface rugose, granulate, and finely, distinctly punctate up to frontoclypeal suture frons and vertex with fine, distinct, dense punctures frontal lobe projecting, angulate. Body elongate, somewhat hour-glass shaped color dark red-brown to nearly black, glossy. Holotype male length 7.4 mm, width 3.4 mm. Stenotothorax wintoni appears to be restricted to the Snake River Valley.ĭescription.
