extending to, and running along the anterior margin of the lobe. Distal lobe extremely 

 small; weakly discontinuous with ridge; concave. 



Median Plate (Fig. 194) 



FM1 oriented strongly postero-proximad. Anterior to posterior section extremely narrow 

 and very long. Proximal margin straight. Articulation with 2Ax extends along the distal 

 margin of the distal ridge over the posterior section of the ventral ridge. Distal margin 

 extremely narrowly and weakly fused to 3Ax. FM2 absent. 



Third Axillary (Fig. 195) 



Head weakly convex; normal length; strikingly bi-lobed, embayment weak. Proximal 

 margin moderately deeply concave. Anterior margin convex; broad; narrow, not enlarged 

 ventrally; from the proximal angle it slopes very strongly antero-distad. Antero-proximal 

 margin broadly extended proximad as a lobe. Proximal lobe weakly convex; short. Antero- 

 distal margin broadly extended anteriad as a lobe. Distal lobe very strongly convex; short. 

 AXCu occupies the proximal one-third of the proximal lobe; convex. FCu strikingly 

 reduced distally; moderately large; distinct; occupies distal two-thirds of the proximal lobe 

 and the proximal one-half of the distal lobe. FA moderately narrow; occupies the distal 

 one-half of the distal lobe. Anterior margin entire. Suture line between FCu and FA present. 

 Suture line between FCu and AXCu present. Suture line between FA and FJ absent. Head 

 and neck junction strikingly reduced, extremely narrow. 



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 strongly curved distad over the distal margin of the tail and strongly curved ventrad 

 reducing the width of the tail; 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; extremely narrow; very short. Dorsal surface oriented laterad. Window 

 absent. FJ+AXJ extremely narrow and short; occupies the anterior half of the tail; 

 moderately sclerotized; curved ventrad. 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. 196) 



Humeral Plate moderately broad and long. Anterior margin strongly sinuate; strongly 

 sclerotized; adjacent to BScA. Apex broadly rounded; clavate; curved ventrad. Dorsal 

 margin convex. Proximal margin convex; strongly curved ventro-proximad. Ventral margin 

 concave. Suture line between FPC+BPC and FC+BC absent.
