Clypeolabral region sparsely setose, vertex bare, epicranial suture distinct. Antennae moderately long (Fig. 31A & C), extending behind body segment 3 dorsally. Head in width <collum <segments 3-4 <5 <2 <6-16; thereafter body gently and gradually tapering. Collum with three transverse rows of setae, 3+3 anterior, 2+2 intermediate and 3+3 posterior; paraterga (Fig. 31B) only slightly declivous, broadly rounded, and narrowly bordered; caudal corner narrowly rounded, slightly declined ventrally, not extending behind tergal margin; posterior quarter of collum slightly rugulose. Tegument of metaterga shining, rugulose-tuberculate, especially on several front metaterga; prozona very finely shagreened, metazona below paraterga faintly rugulose. Metaterga 2-5 with two rows of 2+2 anterior and 3+3 setiferous cones, except segment 3 with 2+1 in anterior row; usually slightly smaller cones in anterior (pre-sulcus) row and more evident ones laterally in posterior row (Fig. 31B & C); thereafter same pattern, but traceable only as insertion points, tuberculation gradually growing obliterate to become nearly wanting from segment 11 on. Tergal setae short,

, about 1/3 metatergal length. Axial line visible both on pro- and metazona. Paraterga extremely strongly developed (Fig. 31B-H), broad, all lying below dorsum (at about 1/3 body height), mostly subhorizontal, slightly upturned on segments 2-5 and 18-19, in lateral view modestly enlarged on pore-bearing segments, thinner on poreless ones (Fig. 31E); shoulders always present, mostly nearly straight and narrowly bordered, fused to callus; caudal corner of most of paraterga very narrowly rounded, extending increasingly beyond tergal margin, slightly curved mesad on segments 16-19 (Fig. 31F). Calluses delimited by a sulcus only dorsally, segment 2 with three evident incisions at lateral edge, following segments with two lateral incisions,

one being particularly evident. Posterior edge of paraterga evidently concave, especially strongly so on segments 16-19. Ozopores evident, lateral, lying in an ovoid groove at about 1/3 in front of caudal corner. Transverse sulcus evident (Fig. 31B-F & H), narrow, rather shallow and only slightly incomplete on metaterga 2 and 3, complete, smooth at bottom, reaching base of paraterga on metaterga 4-18. Stricture between pro- and metazona narrow and shallow, evidently beaded at bottom down to base of paraterga. Pleurosternal carinae complete high crests with a sharp caudal tooth on segments 2-7, thereafter increasingly well divided into a front bulge and a caudal tooth, both increasingly strongly reduced in size, bulge until segment 14, tooth until segment 17. Epiproct (Fig. 31F-H) conical, flattened dorsoventrally, very faintly narrowed caudad, subtruncate, with two evident apical papillae directed caudally, both
