Type specimen. — Male holotype (RVC) from the Great Smoky 

 Mountains National Park, Sevier Co., Tenn., collected by H. Hanson 

 [date and exact locality unknown]. 



Diagnosis. — With the characteristics of the genus. 



Description. — Male, Sequatchie Co., Tenn. Body length 16.8 

 mm., greatest width 3.8 mm. Dorsum uniformly light testaceous 

 brown; antennae, prozonites, and sides below paranota almost 

 colorless. 



Head rather proportionately large, smooth, polished, evenly convex; 

 epicranial suture distinct but not impressed or punctate; interantennal 

 isthmus broad (ca. 0.56 mm.), exceeding length of 2nd antennal 

 article. Genae moderately convex, not margined, without median 

 groove. Antennal socket not rimmed. Antennae long (ca. 3.0 mm.) 

 and slender, 1st article large, globose, with 2 long macrosetae on the 

 dorsal side, each ca. 0.45 mm. in length, otherwise glabrous; 2nd article 

 clavate, distinctly geniculate at base, distally exceeding genal apex; 

 articles 3-6 subsimilar in size and shape, each cylindric, clavate, with 

 sparse and scattered erect setae and a subterminal whorl of 3 or 4 

 macrosetae; 7th article small, subconic, truncate, densely setose, 

 without sensory fields or areas; 4 small terminal sensory cones. 



Collum large, convex, broader than head across mandibles and 

 exceeding ends of 2nd segment, ca. 2.8 mm. wide and 0.95 mm, long; 

 the entire front edge evenly curved, the rear edge nearly straight and 

 distinctly emarginate across dorsum, thence bent forward to the 

 rounded lateral ends of the collum. Surface smooth and polished; 

 cephalolateral submarginal groove distinct only near ends. 



Body segments smooth, evenly convex, and flat, the prozonites and 

 metazonites approximately equal in length and meeting dorsally at a 

 fine sutural line, no interzonal furrow present, and both subsegments 

 of exactly the same diameter. Paranota moderately large, depressed, 

 but slightly interrupting the dorsal convexity, those of midbody 

 segments not overlapping. Anteriormost paranota sloped forward, 

 overlapping, with both corners rounded, the anterior and lateral edges 

 set off by a prominent submarginal depression. Paranota of segments 

 6-19 with posterior corners acutely produced, the anterior corners 

 rounded, scapulorae entu'ely marginal, peritremata flat but prominent, 

 pores small, dorsolaterally located, not in depressions. Posterior edge 

 of paranota concave, with a rounded lobe at the base, this lobe be- 

 comes increasingly prominent on segments 15-16, thence much 

 smaller on segment 17, and absent from segment 18 (fig. 21). Para- 

 nota of segment 19 small sub triangular lobes; epiproct small, partially 

 retracted, broadly rounded.
