concave. Distal arch normal size. Apex weakly curved posteriad and ventrad; aciculate. 

 Distal margin weakly concave. - Ventral view: Proximal arch with a prominent ridge. 

 Distal arch with a narrow and short ridge. Posterior margin with a prominent ridge. 



Second Axillary (Fig. 144) 

 Radial Fulcalare absent. 



Ridges - Dorsal view: Proximal ridge entire; distinct from 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 

 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 weakly waisted. Median 

 section convex. Po stew -proximal angle enlarged. 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 strongly 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; concave. Base moderately broad. Apex rounded; weakly curved 

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

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

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

 moderately reduced. Apex broadly rounded; moderately reduced. Posterior margin straight; 

 moderately reduced. - 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 small; weakly discontinuous with ridge; 

 concave. 



Median Plate (Fig. 145) 



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
