Head in width <collum <segment 4 <2 = 3 <5-16 (♂, ♀); thereafter body gently and gradually tapering. Collum with three transverse rows of setae: 3+3 anterior, 2+2 intermediate, and 2+2 posterior; a very faint incision laterally in posterior 1/3; caudal corner of paraterga pointed, beak-shaped, slightly declined ventrad, extended posteriad, but not surpassing rear tergal margin (Fig. 97A & B). Tegument smooth and shining, prozona very finely shagreened, metaterga smooth and delicately rugulose, leathery; surface below paraterga finely microgranulate. Postcollum metaterga with an anterior transverse row of 2+2, often abraded setae traceable at least as insertion points, a posterior row of 4+4 setae visible only on segment 19. Tergal setae long, slender, about 1/3 metatergal length. Axial line faint, barely traceable on metaterga (♂). Paraterga very strongly developed (Fig. 97A-G), especially well so in ♂, usually slightly upturned to subhorizontal, all lying high (at about 1/3 midbody height), albeit below dorsum;

Calluses delimited by a sulcus only dorsally, thin, especially so on poreless segments. Paraterga 2 broad, anterior edge straight, lateral edge with 2-3 small, but evident incisions in anterior 1/3; posterior edge slightly concave (Fig. 97B & C). Anterior edges of paraterga 3 and 4 evidently convex, of paraterga 5-18 nearly straight and slightly bordered. Lateral edge of paraterga 5-18 with a slight, but more evident incision/tooth in anterior 1/3 and a slightly smaller incision in posterior 1/3 only on pore-bearing segments. Posterior edge of paraterga evidently concave, usually bare, surface without traces of a lobule, on poreless paraterga more concave (Fig. 97A-D). Ozopores evident, lateral, lying in an ovoid groove at about 1/4 in front of caudal corner. Transverse sulcus usually very distinct (Fig. 97A, C & F), slightly incomplete on segments 4, 18 and 19 (not reaching bases of paraterga), complete on metaterga 5-17, deep, usually reaching bases of paraterga, at most faintly beaded at bottom, a little better developed in ♀. Stricture between pro- and metazona narrow, evidently beaded at bottom down to base of paraterga (Fig. 97A-F). Pleurosternal carinae com

Epiproct (Fig. 97E-G) conical, flattened dorsoventrally, with two evident apical papillae, less being especially clear in ♂; tip subtruncate; pre-apical papillae evident, lying close to tip. Hypoproct (Fig. 97G) roundly subtriangular, setiferous knobs at caudal edge well-separated and evident.
