strongly sclerotized; convex. Base narrow. Apex very broadly rounded; straight. Anterior 

 margin concave. Posterior margin weakly enlarged; concave. Distal lobe large; deltoid; 

 much larger than proximal lobe; strongly sclerotized; planate; not sloped ventrad. Anterior 

 margin normal length; straight; oriented postero-distad. Base extremely broad; extends 

 from the apex to the terminus of the ridge. Apex very broadly rounded. Posterior margin 

 straight; not reduced. - Ventral view: Proximal lobe short; convex. Posterior wing process 

 junction ovoid; occupies the posterior margin of the lobe. Distal lobe extremely large; 

 continuous with ridge; weakly concave. 



Median Plate (Fig. 3) 



FM1 oriented posteriad. Anterior to posterior section extremely broad. 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 very 

 broadly and strongly fused to 3Ax. FM2 moderately long; oriented posteriad; very broadly 

 acerose; separated from FM1 by a short, extremely narrow section of membrane. 



Third Axillary (Fig.22) 



Head weakly convex; normal length. Proximal margin weakly convex. Anterior margin 

 weakly convex; not enlarged ventrally. Antero -proximal and antero-distal margins not 

 extended anteriad. AXCu present as a very slender, anteriad extension along the proximal 

 margin of head. FCu normal size; occupies most of the head; weakly ovoid to deltoid. FA 

 moderately narrow; occupies the distal margin of head. Anterior margin entire. Suture line 

 between FCu and FA present. Suture line between FCu and AXCu present. Suture line 

 between FA and FJ present. 



Neck very weakly elevated proximally but not distally. FCu section of neck absent. AXCu 

 forms entire neck; extremely long. Proximal margin elevated as a weakly distinct ridge. 

 Ridge does not curve distad; very long. Dorsal surface of ridge is weakly curved proximad. 

 Posterior section absent. Prong armed with a single extremely narrow and short tooth; 

 oriented postero-proximad. Detached AXCu fragment slenderly ovoid; moderately 

 sclerotized. 



Tail long; narrow; convex. Dorsal surface oriented laterad. Proximal margin strongly 

 elevated dorsad to the dorsal plane of the neck; slopes distad along its entire length. 

 Anterior to antero-median section very weakly concave. Antero-median to posterior section 

 convex; oriented dorso-distad. Window absent. AXA straight. FJ+AXJ and AXA equally 

 narrow. Suture line between FJ and AXJ present. Suture line between FA+AXJ and AXA 

 present. Suture line between AXA and AXCu present. 



Hind Wing Base Description 



First Basal Plate (Fig. 10) 



Humeral Plate extremely narrow; long. Anterior margin convex; lies very distant from 

 BScA and Sc A. Apex very weakly deltoid; extremely narrow; not curved ventrad. Dorsal 

 margin sinuate. Proximal margin convex; very weakly curved ventrad. Ventral margin 

 sinuate. Suture line between FPC+BPC and FC+BC present. FC+BC present as a very 

 long and narrow sclerite posterior to FPC+BPC.
