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

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

 Neck weakly elevated dorsad. FCu section of neck absent. Neck comprised of AXCu. 

 Proximal embayment oriented proximad; small; shallowly concave. Ridge posterior section 

 present. Prong armed with a single tooth. Tooth short; deltoid. Apex weakly rounded. 

 Detached AXCu fragment very small; slender; weakly sclerotized. 



Tail long; moderately broad. Dorsal surface oriented laterad. Anterior section only weakly 

 concave. Median and posterior section very weakly convex to planate. Window absent. FJ 

 and AXJ equally broad; moderately sclerotized. Suture line present. FJ occupies an equal 

 amount of the tail as FJ+AXJ. AXA moderately long; straight. Suture line between FJ+AXJ 

 and AXA present. Suture line between AXA and AXCu strong. 



Hind Wing Base Description 



First Basal Plate (Fig.35) 



Humeral Plate slender. Anterior margin convex sinuate. Apex curved ventrad. Dorsal 

 margin weakly sinuate; slender; distant from BScA. Ventral margin weakly sinuate. Suture 

 lines between FPC+BPC and FC+BC absent. 



Anterior Subcostal Basivenale broadly deltoid; weakly convex; oriented distad. Proximal 

 section separated from the distal section by a prominent suture; as large as the distal 

 section. Antero-median section oriented anteriad; weakly convex; terminus adjacent to HP. 

 Apex broadly rounded; oriented distad. - Subcosta Anterior convex. Bulge not prominent; 

 narrow; separated from BScA by a weak concavity. 



Radial Basivenale strongly open; straight; slender; oriented proximad; continuous with 

 radial stem. Proximal arch slenderly deltoid; oriented posteriad. Anterior section present. 

 Postero- distal margin rounded. Anterior margin weakly convex to straight; narrow. 

 Embayment normal size. Distal arch absent, br weak, br projection moderately narrow; 

 strongly convex; extends anteriad from the antero-proximal margin of br; distinct from 

 BScA. 



Second Basal Plate (Fig.36) 



MA-BMA Junction absent. - MP-BMP Junction not entire. Anterior margin continuous 

 with BMP. - Crimp Patterns absent. - BMP-CuA Brace slender; convex; entire; adjacent 

 to, but distinct from, the distal margin of 2BP. Anterior section continuous with MP. Point 

 of fusion discontinuous. Posterior section continuous with CuA. - BMP-BCuA Brace 

 absent. 



Medial Basivenalia very large; rectangular. Anterior and posterior margins weakly convex. 

 Anterior margin separated from BR by membrane. Posterior margin separated from BCuA 

 by a sclerotized, concave groove. BMA broadly scaphoid; weakly convex; separated from 

 BMP by a broad, shallow groove; lies anteriad, but not proximad of BMP; fully fused to 

 BMP. Proximal arch planate; straight; enlarged antero-proximally; slightly shorter than the 

 distal arch. Distal arch distinct; oriented antero-distad. BMP rectangular; convex; 

 discontinuous with brace; distinct from IBP and BCu. Anterior section rectangular; weakly
