Posterior to the right part of R3 the large RlM-sclerite adjoins, and the two sclerites 

 articulate (A3 in fig. 134, 135, 137). From its central part behind A3 sclerite RIM extends 

 to the left, where it bends left-dorsad (along edge 16; fig. 137, 138) and then occupies the 

 right-dorsal wall of the cbe-invagination (fig. 134). The left- ventral wall and the top of cbe 

 are sclerotised by a plate-like part of R2 (fig. 134- 137); the dorsal margin of this R2-part 

 is fused to the anterior margin of RIM. A line of weaker sclerotisation (13 in fig. 134, 

 138) is probably the boundary between R2 and RIM. 



From its fusion hne 13 with R2 and from articulation A3, RIM extends far posteriad as 

 a dorsoventrally curved plate of irregular shape (fig. 134, 137). It largely occupies the 

 ventral and right walls of the posterior part of the right phallomere (labelled fda and pva 

 in fig. 134- 138). The dorsal margin of RIM folds back to the right to form a sclerotised 

 groove (rge in fig. 134, 138, 140); rge is a posterior continuation of the age-groove on 

 R3 and extends to the posterior edge of the fda-lobe. Dorsal to rge there is an outfolding 

 to the right, which contains the very weak ribbon-like sclerites RIL (fig. 134). At the left 

 end of the fda-lobe there is a dorsal outfolding to the left, which contains sclerite RIK 

 in its ventral wall (fig. 134). Beneath RIK the left marginal part of RIM forms a 

 longitudinal ridge projecting to the left (pva, compare fig. 134 and 139). The dorsal wall 

 of the fda-lobe is mostly membranous (fig. 134), and most anteriorly the tendon tre has 

 its origin (fig. 134, 135, 139). 



Subgenital plate and posterior abdominal segments 



Fig. 109, 110 (posterior segments); fig. 113, 114 (subgenital plate S9). The entire tergite 10 

 TIO, including its ventral part TlOv, is divided along its midline. TlOv is moderately 

 extensive. Separate Pv-sclerites are missing; they are assumed to have been incorporated 

 into the anterior margins of the paraprocts Pp. The sclerites Ca, Cb, and Cc are missing. 

 The bulges next to the cereal bases the Ca-sclerites lie upon in other species, however, 

 are present (compare fig. 59). The articulations A99 are well-developed. The articulations 

 A98 are missing: the sclerotisations Ell and TIO are far away from each other. Each 

 subanal lobe sbl has a small groove (14 in fig. 110) beneath the cereal base.
