Right phallomere 



The long, spatulate R3-sclerite occupies the anterior ventral wall (fig. 280-284). Its right 

 part has a long extension to the posterior (fig. 280, 284). The age-groove or -apodeme is 

 very broad at the anteriormost margins of R3; to the posterior it soon decreases and ends 

 on both sides (fig.266, 284). Sclerite R2 adjoins posterior to the left part of R3; the two 

 sclerites are broadly separated by membrane (at A7 in fig. 282-284). From posterior to A7, 

 R2 extends anteriad and then curves to the left (fig.281, 283, 285). Most ventrally R2 has 

 a strong tooth (fig. 283, 284); in its other parts it forms a very low ridge (fig. 285). At its 

 left end R2 is fused to sclerite RIS (at A6* in fig.281, 283, 285). RIS likewise forms a 

 low ridge (pva in fig.281, 282), and next to its fusion with R2 it has a bulge-like cuticular 

 thickening to the interior (ewe in fig. 282, 283, 285). Posterior to the central part of R3 

 the ventral wall of the right phallomere curves dorsad and anteriad to form a central 

 invagination (cbe in fig.280, 281, 283; compare fig.284 and 285) with R2 and RIS in its 

 left-ventral wall. 



Sclerite RIP adjoins posterior to the right part of R3 (fig.281, 284), and the two sclerites 

 articulate (A3 in fig.281, 282, 284). RIP occupies the ventral wall and the margins of the 

 dorsal wall of a large lobe fda (fig.281, 284). The left anterior tip of RIP closely 

 approaches the free end of RIS (fig.281, 282). Above the fda-lobe there is another, smaller 

 and membranous lobe (dla in fig.280). 



Subgenital plate and posterior abdominal segments 



Fig.262, 263 (posterior segments); fig. 265 (subgenital plate S9). The ventral part of tergite 

 10 TlOv is rather extensive. There are no separate Pv-sclerites; the Pv-sclerotisations are 

 assumed to be incorporated into the anterior parts of the paraprocts Pp (fig.263; a deep 

 indentation at the median margin of each paraproct possibly marks the border between Pp 

 and Pv). The Ca-sclerites lie on curved bulges immediately median to the cereal bases. 

 Cb- and Cc-sclerites are missing. The articulations A98 and A99 are well-developed. The 

 asymmetrical subanal lobes sbl are highly elaborated (fig.263): The left sbl bears a small 

 spine on its posterior edge. The right sbl bears some posteriad-directed bulge-like 

 processes and an anteriad-directed small hook (50 in fig.263, veiled by membrane).
