section moderately short; curved antero-ventrad, basally abruptly, and strongly, curved 

 distad. Median to posterior section extends adjacent to, but lies below, the proximal ridge: 

 very weakly demarcated from the body by an impression. Posterior section acerose; very 

 weakly extended past the posterior margin of lobe. - Ventral view: Proximal ridge slender: 

 short; curved distad; distinct from lobe. Apex aciculate. Anterior to antero-median section 

 digitate; slender; conceals the distal ridge. Median to posterior section obscured by the 

 distal ridge. Distal ridge slender; short. Anterior to median section concealed by the 

 proximal ridge. Median and posterior sections arise from the posterior and proximal 

 margins of the distal lobe; distinct from lobe; broad but short. Median section convex. 

 Postero-median section waisted. Subalare tendon attachment point short and broad; 

 apically not curved ventrad; posterior margin rounded, but truncate; extends posteriad from 

 the median; spatulate; weakly visible dorsally. 



Body - Dorsal view: about as long as broad. Proximal lobe moderately long and broad; 

 deltoid; arises medially from the ridge, but depressed below the ridge; strongly sclerotized; 

 convex; oriented proximad. Base moderately broad. Apex broadly rounded; weakly curved 

 anteriad. Anterior margin very weakly concave. Posterior margin very weakly enlarged; 

 very weakly concave. Distal lobe moderately small and broad; deltoid; shorter but broader 

 than the proximal lobe; moderately sclerotized; concave. Anterior margin convex. Apex 

 aciculate; oriented proximad. Posterior margin straight; very weakly reduced. - Ventral 

 view: Proximal lobe moderately large; convex. Posterior wing process junction formed as 

 a large, slenderly ovoid convexity which conceals the posterior section of the proximal 

 lobe from the base to the apex; occupies the posterior section of the lobe. Distal lobe large 

 and broad; discontinuous with ridge; deeply concave. 



Median Plate (Fig.82) 



FM1 oriented strongly postero-distad. Anterior section narrow. Median to posterior section 

 moderately narrow. Proximal margin convex. Articulation with 2Ax extends from the 

 antero-distal margin of the distal lobe to the posterior section, over the posterior section 

 of the ventral ridge. Distal margin narrowly and weakly fused to 3Ax. FM2 moderately 

 long and slender; oriented postero-distad; acerose. Anterior to postero-median section 

 separated from FM1 by a long, narrow section of membrane. Postero-median to posterior 

 section fused to FM1. 



Third Axillary (Fig.83) 



Head very broad; dorso-ventrally flattened. Dorsal surface deeply and extensively concave. 

 Proximal margin convex. Anterior margin dorsally weakly convex; not enlarged ventrally: 

 from proximal angle it is oriented antero-distad. Ante ro -proximal margin not extended 

 anteriad. Antero-distal margin not extended ventrad; narrow. Posterior margin with a weak 

 concavity which extends to the tail. FCu strongly reduced distally; moderately large; 

 distinct; occupies about half of the head; broadly ovoid. FA moderately large; occupies 

 about half of the head; smaller than FCu. Anterior margin entire; not reduced by FCu. 

 AXCu absent. Suture line between FCu and FA present. Suture line between FCu and 

 AXCu present. Suture line between FA and FJ absent.
