Third Axillary (Fig. 167) 



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

 weakly concave; broad; narrow, not enlarged ventrally; from the proximal angle it slopes 

 antero-distad. Antero-proximal margin not extended anteriad. Antero-distal margin weakly 

 extended anteriad. AXCu occupies the proximal one-fifth of head; convex. FCu normal 

 size; distinct: occupies the central three-fifths of the head; deltoid. FA moderately narrow; 

 occupies the distal one-fifth 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 

 absent. 



Neck elevated proximally and weakly so distally. FCu section of neck absent. AXCu forms 

 entire neck; extremely small. Proximal margin elevated as a very narrow and short ridge. 

 Ridge extends to median of the proximal margin of tail; very short. Dorsal surface of ridge 

 is weakly curved proximad; enlarged dorsally relative to AXA. Prong armed with a single 

 broad but short tooth; oriented postero-dorsad. Detached AXCu fragment saddle-shaped; 

 strongly curved ventrad both anteriorly and posteriorly; slender: moderately sclerotized. 



Tail reduced; deltoid; short. 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 concave. Antero-median to posterior section convex; 

 oriented dorso-distad. Window absent. FJ+AXJ broad; extends close to the dorsal plane of 

 the neck; occupies the anterior half of the tail; moderately sclerotized: curved distad. 

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

 AXA extremely short and narrow; more strongly sclerotized than FA+AXJ; occupies the 

 posterior half of the tail: curved postero-distad. Suture line between AXA and AXCu 

 present. 



Hind Wing Base Description 



First Basal Plate (Fig. 168) 



Humeral Plate moderately broad; long. Anterior margin convex; strongly sclerotized; 

 adjacent to BScA. Apex deltoid: moderately narrow; curved ventrad. Dorsal margin 

 concave. Proximal margin weakly convex; curved ventrad. Ventral margin sinuate. Suture 

 line between FPC+BPC and FC+BC absent. 



Anterior Subcostal Basivenale oriented distad; broadly ovoid; convex; moderately dorsad. 

 Proximal and distal sections separated by a prominent suture. Proximal section weakly 

 extended anteriorly and postero-proximally as a moderately broad convexity; larger than 

 the distal section. Distal section discontinuous with the ScA bulge; separated by a 

 moderately deep concavity. Apex broadly rounded; oriented distad. - Subcosta Anterior 

 moderately convex: moderately extended posteriorly. Bulge moderately broad. 



Radial Basivenale convex; open; discontinuous with radial stem; angled antero-proximad; 

 broadly rectangular. Proximal arch slenderly deltoid; curved postero-distad. Anterior 

 strikingly reduced by a greatly enlarged br; discontinuous with the anterior margin of BR. 

 Posterior margin weakly concave; surrounds the BMA arch apex. Postero-distal margin 

 truncate. Anterior margin depressed below the posterior margin of ScA bulge; extremely
