Hind Wing Articulation Description 



First Axillary (Fig.38) 



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

 oriented weakly postero-distad. Postero-proximal margin weakly enlarged proximally. 

 Proximal margin strongly enlarged ventrally. 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; deeply 

 concave; oriented disto-ventrad and curved posteriad. Apex narrow. 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. Head and neck dorsal surface weakly curved proximad. 



Neck normal width and length; weakly oriented antero-distad; recurved relative to tail. 

 Proximal margin- convex. Distal margin weakly concave; broadly articulated with 2Ax. 

 Distal embayment shallow; broad. 



Tail - Dorsal view: weakly concave. Proximal arch normal size. Dorsal surface weakly 

 concave. Antero -proximal margin concave. Postero-proximal margin weakly convex. 

 Articulation with PRR strong but short. Posterior margin weakly concave. Distal arch 

 normal size; slightly larger than the proximal arch; weakly oriented postero-proximad. 

 Apex aciculate; weakly curved ventrad and posteriad. Distal margin very weakly concave. 

 - Ventral view: Proximal and distal arches with ridges. Posterior margin with a prominent 

 ridge. 



Second Axillary (Fig. 39) 



Radial Fulcalare present as re-enforced membrane. 



Ridges - Dorsal view: Proximal ridge entire; distinct from lobe. Apex lengthened anteriorly, 

 beyond the ventro-distal ridge apex. Anterior to antero-median section partially concealed 

 distally by distal ridge; strongly curved ventro-distad beneath the distal ridge; separated 

 from the distal ridge by a broad gap which extends to the mid-line of 2Ax. Antero-median 

 to posterior section moderately broad; elevated above the distal ridge. Posterior section 

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

 from lobe. Apex narrowly falcate; moderately short; convex; very strongly curved distad; 

 reduced distally and anteriorly, revealing the distal and apical sections of the dorso- 

 proximal ridge. Anterior section slender; moderately short; shorter than the proximal ridge; 

 strongly curved proximad; recurved, but curves abruptly ventrad towards the apex. Fuses 

 with the anterior margin of the distal lobe. Subapical to antero-median section strongly 

 oriented postero-distad. Median to posterior section strongly depressed ventrad, curving 

 beneath the antero-median section of the dorso-proximal ridge, giving the appearance that 

 the dorso-distal ridge and lobe twists around the dorso-proximal ridge and lobe. - Ventral 

 view: Proximal ridge moderately broad; indistinct from the proximal lobe. Apex aciculate. 

 Anterior section broadly acerose; weakly curved proximad; conceals the distal ridge 

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

 moderately broad. Median and posterior sections arise from the proximal and posterior
