Hind Wing Articulation Description 



First Axillary (Fig.45) 



Head - Dorsal surface normal size. Antero-dorsal margin normal width; weakly deplanate; 

 oriented weakly postero-distad. Ant ero -proximal margin extended anteriad as a large 

 convexity. Postero-proximal margin weakly enlarged proximally. Proximal margin 

 strongly enlarged ventrally; convex. FSc2 base normal width. Apex rounded; oriented 

 postero-distad. Anterior surface broad; very long; not waisted medially. FScl very weak. 

 Ventral projection tapers from base to apex; short but of normal width; shorter than FSc2; 

 deeply concave; oriented disto-ventrad and curved posteriad. Apex narrow. Dorsal surface 

 concave. - Ventral surface flattened. Concavity located in the preapical area; surrounded 

 by three unequally strong ridges of unequal length. Distal embayment oriented dorsad. 

 FSc2 deltoid; broad; very convex; oriented distad and weakly dorsad; not enlarged dorsally. 

 Proximal margin broadly fused to the ventrad projection. Dorsal surface convex. Ventral 

 surface concave. Head and neck dorsal surface weakly curved proximad. 

 Neck normal width and length; narrower than head; recurved relative to tail; weakly 

 oriented antero-distad. Proximal margin straight. Distal margin concave; broadly 

 articulated with 2 Ax. Distal embayment concave; moderately deep; broad. 

 Tail - Dorsal view: concave. Proximal arch normal size; extended postero-proximad and 

 weakly so postero-distad. Dorsal surface weakly concave. Ant ero -proximal margin 

 convex. Postero-proximal margin convex. Articulation with PRR strong but short. 

 Posterior margin weakly concave. Distal arch normal size; weakly curved ventrad; 

 extended postero-distad. Apex aciculate; strongly curved ventrad and posteriad. Distal 

 margin very weakly concave. - Ventral view: Proximal arch with a broad ridge. Posterior 

 margin with a narrow but prominent ridge. Distal arch with a very small ridge. 



Second Axillary (Fig.46) 



Radial Fulcalare not sclerotized; present only as re-enforced membrane. 

 Ridges - Dorsal view: Proximal ridge entire; distinct from lobe. Anterior to antero-median 

 section concealed by the distal ridge. Antero-median to posterior section moderately broad; 

 strongly elevated above the distal ridge; extends adjacent to the distal ridge. Posterior 

 section acerose; strikingly enlarged above the distal ridge; oriented posteriad. Distal ridge 

 distinct from lobe; extends anteriorly and curves very weakly proximally from the dorso- 

 distal lobe base. Apex extremely broad; falcate; moderately short; convex; oriented weakly 

 ventro-proximad. Anterior section broad; moderately short; curved proximad. Median 

 section abruptly curved ventrad. Posterior section extends adjacent to, but lies below, the 

 proximal ridge. - Ventral view: Proximal ridge very broad; indistinct from lobe. Apex very 

 broadly rounded; curved distad. Anterior section very broad; sinuate; conceals the distal 

 ridge proximally. Median to posterior section concealed by the distal ridge. Distal ridge 

 extremely broad. Anterior to median section concealed by the proximal ridge. Median and 

 posterior sections arise from the proximal, posterior and postero-distal margins of the distal 

 lobe; indistinct from lobe; short; extremely broad. Median section convex. Postero-median 

 section waisted. Subalare tendon attachment point moderately long and narrow; extends 

 posteriad from the median; not curved ventrad; spatulate; moderately visible dorsally.
