Third Axillary (Fig. 132) 



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 very 

 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 

 very 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 weakly 

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

 Anterior to antero-median section deeply 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. 133) 



Humeral Plate moderately broad and long. Anterior margin concave; strongly sclerotized; 

 adjacent to BScA. Apex rounded; moderately broad; curved ventrad. Dorsal margin 

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

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



Anterior Subcostal Basivenale oriented distad; broadly ovoid; convex; moderately elevated 

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

 extended postero-proximad as a very broad convexity; larger than the distal section. Distal 

 section discontinuous with the Sc A bulge; separated by a moderately deep concavity. Apex 

 broadly rounded; oriented distad. - Subcosta Anterior moderately convex; moderately 

 extended posteriad. Bulge 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; does not surround the BMA arch apex. Po stem -distal
