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

 line between FA and FJ present. 



Neck moderately elevated proximally; distally very weakly so. FCu section of neck absent. 

 AXCu forms entire neck. Proximal margin elevated as a weak ridge; extends to mid-line 

 of proximal margin of tail; short. Prong armed with a single slender tooth. Ridge enlarged 

 dorsally relative to AXA. Detached AXCu fragment deltoid; moderately sclerotized. 



Tail broadly deltoid; long; planate. Dorsal surface oriented mesad. Anterior section broad; 

 concave; weakly calceolate. Posterior section concave to flat. Window weak. FJ+AXJ 

 slender; occupies distal third of tail; strongly sclerotized. Suture line between FJ and AXJ 

 present. Suture line between FA+AXJ and AXA present. AXA more weakly sclerotized 

 than FA+AXJ; occupies more than half of the tail; straight. Suture line between AXA and 

 AXCu present: 



Hind Wing Base Description 



First Basal Plate (Fig.63) 



Humeral Plate slender; apically weakly clavate. Anterior margin sinuate; strongly 

 sclerotized. Apex very broad; clavate; curved ventrad. Dorsal margin slender; distant from 

 BScA; strongly sinuate. Proximal margin J-shaped; curved proximo-ventrad. Ventral 

 margin strongly sinuate. Distal section narrow. Suture line between FPC+BPC and FC+BC 

 absent. 



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

 Proximal and distal sections separated by a prominent suture. Proximal section about the 

 same size as the distal section. Apex broadly rounded. Distal section extremely broad; 

 separated from ScA by a shallow concavity. - Subcosta Anterior weakly convex. Bulge 

 extremely broad. 



Radial Basivenale very small; convex; narrowly open; weakly angled antero-proximad; 

 continuous with radial stem. Proximal arch slenderly deltoid; long; curved postero- 

 proximad; continuous with the anterior margin of BR. Postero-distal section rounded. 

 Anterior margin convex; moderately narrow; weakly elevated dorsad. Embayment normal 

 size. Distal arch extremely weak; oriented posteriad. br strongly sclerotized; occupies the 

 antero-proximal corner of BR; weakly discontinuous with BR. br projection apically 

 broad; medially concave; indistinct from BSc. 



Second Basal Plate (Fig. 64) 



MA-BMA Junction absent. - MP-BMP Junction: MP discontinuous with BMP; arises from 

 below the distal margin. - Crimp Patterns absent. - BMP-CuA Brace present; slender; 

 strongly convex; entire; distant from the distal margin of 2BP; extends postero-proximad. 

 Anterior section reduced; not fused with BMP or the MP-BMP junction; arises from below 

 the antero-distal margin of 2BP; more strongly convex than BMP. Posterior section 

 continuous with CuA; fused to the antero-proximal angle of CuA. Point of fusion not 

 marked by a suture line. - BMP-BCuA Brace absent.
