Clypeolabral region densely setose, vertex sparsely setose, epicranial suture distinct.

Head in width <collum <segments 3 and 4 <2 <5-16 (♂, ♀); thereafter body gently and gradually tapering. Collum with three transverse rows of setae: 4+4 anterior, 2+2 intermediate, and 3+3 posterior; paraterga subtriangular, lying in a slightly rugulose posterior 1/3 of collum, slightly declined ventrally and continuing collum convexity (Fig. 25B); caudal corner of paraterga pointed. Tegument smooth and shining, prozona very finely shagreened,

leathery, faintly rugulose, below paraterga microgranulate. Metaterga 2-18 with an anterior transverse row of 2+2, mostly abraded setae; caudal row barely traceable only as 3+3 or 4+4 insertion points better visible laterally as minute knobs or oblong wrinkles. Metatergum 19 with 3+3 anterior and 4+4 posterior setae, the latter also borne on minute knobs. Tergal setae simple, rather long, about 1/3 metatergal length. Axial line barely traceable only on some metaterga, never complete. Paraterga very strongly developed (Fig. 25A-H), especially well so in ♂, all lying below dorsum (at about 1/3 body height), subhorizontal, in lateral view modestly enlarged on pore-bearing segments, thinner on poreless ones; shoulders always present, regularly rounded and narrowly bordered, fused to callus; caudal tip of all paraterga pointed, beak-like, lying within rear tergal margin or almost so on segments 2-7, thereafter extending increasingly beyond it, best developed and slightly curved mesad on segments 17-19 (Fig. 25F). Calluses delimited by a sulcus both dorsally, and, albeit more poorly so, ventrally, in dorsal view narrower on poreless segments than on pore-bearing ones, with three small, but evident lateral incisions on callus 2, with two similar incisions on following poreless segments, with one, often setigerous incision in front of pore on pore-bearing segments. Posterior edge of paraterga evidently concave, especially strongly so on segments 16-19. Ozopores evident, lateral, lying in an ovoid groove at about 1/4 in front of caudal corner. Transverse sulcus highly incomplete and visible only mid-dorsally on segment 2, complete on metaterga 5-18, narrow, rather deep, reaching bases of paraterga, finely beaded at bottom, better developed in ♀. Stricture between pro- and metazona narrow and rather shallow, evidently beaded at bottom down to base of paraterga (Fig. 25B, D, E & H). Pleurosternal carinae complete crests with a sharp caudal tooth on segments 2 and 3, onward as increasingly poorly developed, flat ridges with small caudal teeth until segment 12, thereafter only as an increasingly small, sharp, caudal tooth on segment 16. Epiproct (Fig. 25F-H) conical, flattened dorsoventrally, with two evident apical papillae directed ventrocaudally, subtruncate at tip; pre-apical papillae large, lying close to tip. Hypoproct (Fig. 25G) subtriangular, caudal margin rounded, setiferous knobs at caudal edge very large and well-separated.
