Median Plate (Fig. 110) 



FM1 oriented strongly postero-distad. Anterior section narrow. Median to posterior section 

 moderately narrow. Proximal margin convex. Articulation with 2Ax extends from the 

 antero-distal margin of the distal lobe to the posterior section over the posterior section 

 of the ventral ridge. Distal margin broadly but weakly fused to 3Ax. FM2 absent. 



Third Axillary ( Fig. Ill) 



Head weakly convex: strikingly reduced posteriorly. Proximal margin shallowly concave. 

 Anterior margin weakly concave; broad: enlarged ventrally. Antero-proximal margin not 

 extended anteriad. Antero-distal margin extended distad. FCu normal size: distinct: 

 occupies two-thirds of the head: ovoid. Proximal margin not reduced by AXCu. Posterior 

 margin weakly reduced by an enlarged AXCu. Distal margin reduced by an enlarged FA. 

 FA moderately small; extended proximad. Anterior margin entire. AXCu weakly extended 

 anteriad onto head. Suture line between FCu and FA present. Suture line between FCu 

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



Neck elevated proximally: distally depressed. FCu section of neck absent. AXCu forms 

 entire neck. Proximal margin very strongly and extensively elevated as a narrow ridge. 

 Ridge extends close to the postero-proximal margin of the tail; very long. Dorsal surface 

 of ridge is weakly curved distad: enlarged dorsally relative to AXA. Embayment 

 moderately deep. Prong armed with a single short tooth: oriented proximo-dorsad: narrow. 

 Detached AXCu fragment slender: rectangular; weakly sclerotized. 



Tail reduced: moderately deltoid: short. Dorsal surface oriented mesad. Anterior to 

 posterior section concave. Window absent. FJ+AXJ narrow: occupies the distal half of the 

 tail: weakly sclerotized. Suture line between FJ and AXJ absent. Suture line between 

 FA+AXJ and AXA present. AXA as equally sclerotized as FA+AXJ; the former occupies 

 the postero-proximal half of the tail: straight. Suture line between AXA and AXCu present. 



Hind Wing Base Description 



First Basal Plate (Fig. 1 12) 



Humeral Plate extremely broad. Anterior margin convex: weakly sclerotized; lies adjacent 

 to BScA. Apex broad: curved ventrad. Dorsal margin deeply concave. Proximal margin 

 convex: curved proximo-ventrad: clavate. Ventral margin concave. Suture line between 

 FPC+BPC and FC+BC absent. 



Anterior Subcostal Basivenale oriented distad: slenderly ovoid: convex: strongly elevated 

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

 extended as a moderately narrow convexity: about as large as the distal section. Distal 

 section continuous with ScA bulge; separated by a deep concavity. Apex broadly spatulate; 

 strongly curved ventrad beneath the postero-proximal margin of the ScA bulge. - Subcosta 

 Anterior weakly convex. Bulge broad. 



Radial Basivenale extremely broad but very short: convex; narrowly open: discontinuous 

 with the radial stem: angled proximad: slenderly ovoid. Proximal arch strikingly broad:
