with a weak ridge. Posterior margin with a prominent ridge. Distal arch with a very slender 

 ridge. 



Second Axillary (Fig. 130) 



Radial Fulcalare present; moderately sclerotized; slender. 



Ridges - Dorsal view: Proximal ridge entire; distinct from lobe. Apex partially obscured 

 by the distal ridge; waisted. Anterior section distal margin exposed. Antero-median to 

 postero-median section moderately enlarged above and laterad over the distal ridge. 

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

 proximad; slender; long; distinct from lobe; 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 

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

 completely conceals the distal ridge. Apex 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; broad; moderately long. Antero- 

 median section weakly waisted. Median section convex. Postero-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; weakly visible dorsally. 



Body - Dorsal view: about as long as broad. 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; weakly 

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

 Distal lobe moderately long and broad; deltoid; shorter than proximal lobe; moderately 

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

 postero-distad; moderately reduced. Apex aciculate. Posterior margin straight; weakly 

 reduced. - Ventral view: Proximal lobe 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 partially running along the 

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

 concave. 



Median Plate (Fig. 131) 



FM1 oriented strongly postero-proximad. Anterior to posterior section moderately broad. 

 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 short and narrow section of membrane.
