 Issued from : J.C. von Vaupel Klein inZool. Meded., Leiden, 1980, 55 (12). [p.138, Fig.3, a-b]. Female: a, left A1 (lateral view); b, right A1 (medial view). Nota: A1 reaching just beyond the genital segment; 24-segmented, segments 8 and 9 being fully coalesced; fusion of segments 24 and 25 intimate, but not quite complete. The proximal segments, i.e. up to and including segment 12, are rather short and more compactly built, whereas the distal segments 13 to 24 rather long and slender; the terminal segment is minute. Large setae are prsent on segments nos. 3, 7, 8+9, 14, 16, 18, and 21, in each case one only, all placed distally along the frontal edges.

Female: a, left A2 (lateral view); b, right A2 (medial view); c, right Md (antero-ventral); d, detail of chewing plate of Md (anterior view) (smaller setiform tooth broken-off); e, palp of left Md; f, gnathobase of left Md (ventral view); g, detail of chewing plate of right Md (anterior view) (larger setiform tooth broken-off; setiform protrusions in the two smaller bicuspidate molariform complexes indicated by minute arrows); h, detail of proximal multicuspidate molariform complex of right Md (posterior view), with both setiform teeth in situ.

 Issued from : J.C. von Vaupel Klein inZool. Meded., Leiden, 1980, 55 (12). [p.140, Fig.4, i, j]. Female: i, left Mx1(anterior view); j, right Mx1 (posterior view). Nota: Basal segments of Mx1 completely coalesced. The moderately heavy 1st inner lobe equipped with a total of 9 setae along its internal margin: the two proximal ones are comparatively long and slender, with rounded-off tips, and sparsely spinulose; the remaining 7 setae are stout and powerful, tapering to more acutely pointed tips, and provided with strong, double serrations along their distal parts. These latter setae are placed alternately on the anterior and posterior sides of the lobe's edge, starting with a posteriorly placed distalmost seta, then followed by and anteriorly placed penultimate one, and so on. Thus, there are a total of 4 setae along the posterior side of the margin, which are serrate only; the 3 setae placed anteriorly are likewise serrate, but, moreover, also sparsely spinulose in their medial portions. There is 1 smaller, serrate seta situted submarginally on the anterior face of the first inner lobe, and a total of 3 combined serrate-spinulose setae have been observed on thelobe's posterior surface. One small brush of hairs only at the apical edge of this particular lobe. The second inner lobe rather slender, and shorter than the first.. It bears 4 setae apically, which are set closely together, rather long, but apparently stiff as well. 3 of these setae are serrate distally, and sparsely spinulose along most of their lengths; 1 seta is spinulose only. The second inner lobe overreaches the small and only partly free third inner lobe. The third inner lobe is reduced and bears 2 weakly developed setae apically: 1longer, plumose one, and 1 very short, slender seta, sparsely plumose as well. There is a long-drawn brush of thin hairs along yjis lobe's anterior surface.
