dd. Pygidium with setae large, longer than median pair of lobes, 

 four on each side; median pair of lobes with lateral notches 

 only, rarely with mesal notch, subquadrangular, parallel or 

 somewhat convergent, longer than broad, symmetrically 

 bluntly rounded; second pair of lobes two-thirds size 

 of median, subadjacent to median, oblique, broadly rounded, 

 deep lateral notches; plates arranged 2, 1-2, 0, those of me- 

 dian incisura small, dagger-shaped, two, those of second in- 

 cisura sometimes furcapectinae, one to two; setae large, 

 longer than median lobes, four on each side. — Madeira on

 lobes large, prominent, rounded, crenulate; second pair of lobes 

 small, nearly as broad as median, mesal margin straight, lateral 

 margin oblique, crenulate, lobes inconspicuous; dorsal oracera- 

 tubae arranged in four Indefinite rows on each side; anus five 

 times Its width from caudal margin and same distance from vulva;

aa. Body with cephalic margin thickened and uniformly crenulate; 

 pygidium with median pair of lobes quadrangular, broad with deep 

 lateral and mesal notches, distal margin bluntly rounded; second 

 pair of lobes much smaller, pointed, large lateral notch; pectinae 

 subequal in length to median lobes, deeply lacinate, arranged 2, 2,
