ridge. Posterior section weakly enlarged above the distal ridge; broadly curved postero- 

 proximad; slender; long; distinct from lobe; strongly extended past the posterior margin 

 of lobe. Distal ridge weakly distinct from lobe. Apex narrow; convex; strikingly elongate; 

 aciculate; strongly curved ventro-proximad; the distal margin is reduced revealing the 

 ventral section of the distal lobe. Anterior section slender and strikingly elongate; straight 

 and anteriad. Median to posterior section dorsally concealed by the proximal ridge. 

 Posterior section very strongly extended past the posterior margin of lobe. - Ventral view: 

 Proximal ridge anteriorly completely conceals the distal ridge. Apex weakly aciculate. 

 Anterior to antero-median section moderately narrow and very long; curved distad. Median 

 to posterior section obscured by the distal ridge. Distal ridge median and posterior sections 

 arise from the posterior and proximal margins of the distal lobe; distinct from lobe; 

 moderately broad; moderately long. Antero-median section not waisted. Median section 

 convex. Po stem -proximal angle not reduced. Postero -distal angle not extended postero- 

 distad. Subalare tendon attachment point short and moderately broad; apically not curved 

 ventrad; posterior margin medially concave; extends posteriad from the median; the 

 postero-dorsal section of the proximal ridge is moderately extended past the terminus of 

 the subalare tendon attachment point; strongly visible dorsally. 



Body - Dorsal view: slender and strikingly elongate. Proximal lobe long; deltoid; oriented 

 proximad; arises from the postero-medial section of the ridge; depressed below the ridge; 

 strongly sclerotized; weakly concave. Base moderately broad. Apex rounded; curved 

 anteriad. Anterior margin concave. Posterior margin weakly enlarged; concave. Distal lobe 

 short and moderately broad; deltoid; slightly shorter than proximal lobe; moderately 

 sclerotized; planate; moderately sloped ventrad. Anterior margin weakly convex; oriented 

 antero-distad; moderately reduced. Apex broadly rounded; strongly reduced. Posterior 

 margin straight. - Ventral view: Proximal lobe moderately short; convex. Posterior wing 

 process junction formed as a slender, ridge-like convexity; occupies the postero-proximal 

 section of the lobe and is greatly lengthened anteriorly, extending to, and running along 

 the anterior margin of the lobe. Distal lobe moderately small; weakly discontinuous with 

 ridge; concave. 



Median Plate (Fig. 159) 



FM 1 oriented strongly postero-proximad. Anterior 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 extremely narrowly and weakly fused to 3Ax. FM2 moderately short; oriented 

 proximad; acerose; separated from FM1 by a long, narrow section of membrane. 



Third Axillary (Fig. 160) 



Head weakly convex; normal length; very weakly bi-lobed. Proximal margin shallowly 

 concave. Anterior margin weakly concave; broad; narrow, not enlarged ventrally; from the 

 proximal angle it slopes antero-distad. Antero-proximal margin not extended anteriad. 

 Antero-distal margin weakly extended anteriad. AXCu occupies the proximal one-fifth of 

 head; convex. FCu normal size; distinct; occupies the central three-fifths of the head;
