ridge. Posterior margin with a prominent but very slender ridge. Distal arch with a small 

 ridge. 



Second Axillary (Fig. 151) 

 Radial Fulcalare absent. 



Ridges - Dorsal view: Proximal ridge entire; distinct form lobe. Apex nearly completely 

 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; 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 aciculate. Anterior to 

 ant ero -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; moder- 

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

 Postero-proximal angle not reduced. Postero-distal angle reduced. 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 very moderately extended past the terminus of the subalare tendon 

 attachment point; moderately 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; longer than proximal lobe; moderately sclerotized; 

 planate; weakly sloped ventrad. Anterior margin weakly convex; oriented antero-distad; 

 moderately reduced. Apex broadly rounded. Posterior margin straight; moderately 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 running along the anterior margin of the 

 lobe. Distal lobe small; weakly discontinuous with ridge; concave. 



Median Plate (Fig. 152) 



FM1 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.
