Hind Wing Articulation Description 



First Axillary (Fig.20) 



Head - Dorsal surface normal size. Antero-dorsal margin oriented weakly postero-distad; 

 normal width; planate. Antero -proximal margin strongly enlarged ventrally. Postero- 

 proximal margin weakly and narrowly enlarged proximally. FSc2 base normal width. Apex 

 oriented postero-distad; rounded. Anterior surface broad; very long; not waisted medially. 

 FScl absent. Ventral projection short but of normal width; tapers from base to apex; 

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

 located in the preapical area; surrounded by three unequally strong ridges. Distal 

 embayment oriented dorsad. FSc2 oriented distad and weakly dorsad; deltoid; extremely 

 short and broad. Dorsal surface not enlarged. Head and neck dorsal surface weakly curved 

 proximad. 



Neck normal width and length; weakly oriented antero-distad; broadly articulated with 

 2Ax; discontinuous with tail. Proximal margin entire; curved ventrad; convex. Distal 

 margin concave. Distal embayment weakly concave; shallow but broad. 

 Tail - Dorsal view: Proximal arch normal size; weakly concave. Antero -proximal margin 

 concave. Po stem -proximal margin convex. Articulation with PRR very weak. Posterior 

 margin moderately concave. Distal arch normal size. Apex weakly curved ventrad and 

 posteriad; aciculate. Distal margin straight. - Ventral view: Proximal, distal and posterior 

 margins with very weak ridges. 



Second Axillary (Figs. 16, 21) 



Radial Fulcalare strikingly broadly ovoid and extremely large; very strongly sclerotized; 

 fused to the entire anterior margin of 2 Ax distal lobe and ridge; almost indistinct from 2 Ax. 

 Ridge - Dorsal view: Proximal ridge only very weakly differentiated from the body. Apex 

 to postero -median section absent. Postero-median to terminus extremely narrow along the 

 entire length; straight; very short; weakly distinct from lobe; strongly depressed below the 

 distal ridge; weakly extended past the posterior margin of lobe; straight; oriented posteriad. 

 Distal ridge only very weakly differentiated from the body. Apex oriented ventro-proximad; 

 convex and broadly falcate; extremely short. Anterior section arises from the anterior 

 margin of the distal lobe; extremely short; very broad; curves proximad. Anterior to 

 terminus absent. Articulation with lAx weak; anteriorly lAx distal arch articulates below 

 the proximal margin of the distal lobe; posteriorly lAx distal arch articulates between the 

 proximal ridge and distal lobe. - Ventral view: Proximal and distal ridges are only weakly 

 differentiated from each other; proximal ridge completely conceals the distal ridge. Apex 

 broadly truncate. Anterior to antero-median section stout; curved distad. Median to 

 posterior section not visible; obscured by the distal lobe. Subalare tendon attachment point 

 moderately long and narrow; extends posteriad from the median; visible dorsally along 

 the postero-proximal and postero-distal margins of the body; the postero-dorsal section of 

 the proximal ridge is extended past the terminus of the subalare tendon attachment point. 

 Terminus narrowly rounded; not curved ventrad; oriented posteriad. 

 Body - Dorsal view: about as long as broad. Proximal lobe oriented proximad; arises 

 ventrally from the postero-medial section of the distal lobe and ridge; short; clavate;
