rotises the spine sra; the left end of RIH is somewhat spoon-shaped. The right end of 

 RIH extends posteriorly onto the process pra (fig.74) and articulates anteriorly with the 

 dorsal arm of RIF (A8 in fig.74). The tendon tre (fig.74), a very long and narrow 

 invagination of the cuticle, has its origin in the anteriormost dorsal wall of the fda-lobe. 

 The ventral tooth pia is anteriorly sclerotised by the second arm of RIF (fig.77, 78); 

 posteriorly pia is sclerotised by RIG, which articulates with RIF in the dorsal wall of 

 pia (A9 in fig. 78). RIG has a narrow extension to the right, which reaches the pra-process 

 and maintains a narrow connection with the dorsal RIH (fig.74, 77, 78). Anterior to this 

 sclerite bridge there is a large membranous area (17 in fig.74, 77). 



Subgenital plate and posterior abdominal segments 



Fig. 58, 59 (posterior segments); fig. 62 (subgenital plate S9). The ventral part of tergite 10 

 TlOv is very extensive. Strip-like Pv-sclerites are present; they are completely free from 

 the paraprocts Pp. The Ca-sclerites lie on curved bulges immediately median to the cereal 

 bases. The Cc-sclerites are dorsoventrally curved plates on paired shallow outfoldings 

 beneath the anterior margin of TlOv and above the subanal lobes sbl. Cb-sclerites are 

 missing. The articulations A98 and A99 are well-developed.
