Body - Dorsal view: Proximal lobe short; broad; arises ventrally and postero-medially 

 from the ridge; moderately sclerotized; flat; oriented proximad. Base strongly enlarged 

 anteriorly and posteriorly; broad. Anterior and posterior margins greatly enlarged; 

 concave. Apex broadly rounded; curved anteriad. Distal lobe small and broad; roundly 

 deltoid; reduced distally; broader but shorter than the proximal lobe; moderately 

 sclerotized; convex. Base very broad. Apex broadly rounded. Anterior margin normal 

 length; weakly concave. Posterior margin weakly concave. - Ventral view: Proximal lobe 

 extremely small; weakly convex; nearly completely obscured by the distal ridge. Posterior 

 wing process junction small; ovoid; occupies the posterior margin of the lobe. Distal lobe 

 weakly concave; continuous with ridge; small. 



Median Plate (Fig.47) 



FM1 oriented proximad anteriorly and postero-proximad medially and posteriorly; 

 rectangular. Anterior section narrow. Median and posterior section extremely broad. 

 Proximal margin straight. Articulation with 2Ax extends from apical angle of the distal 

 lobe over the posterior section of the ventral ridge. Distal margin moderately narrowly 

 fused to 3Ax. FM2 oriented proximad and weakly posteriad; rectangular; separated from 

 FM1 by a moderately wide section of membrane; very small; acerose. 



Third Axillary (Fig.48) 



Head strikingly convex; moderately broad; normal length. Anterior margin narrow; not 

 enlarged ventrally; weakly convex. FCu normal size; occupies the anterior to antero-medial 

 section of head. Posterior and proximal margins reduced by a greatly enlarged AXCu. 

 Distal margin strongly reduced by FA and AXCu. FA broad; convex; extended distad along 

 its entire length. AXCu large; occupies about half of the head. Anterior margin extended 

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

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



Neck elevated dorsad. FCu section of neck absent. Neck comprised by AXCu. Proximal 

 embayment oriented proximad; small; shallowly concave. Ridge posterior section present. 

 Prong armed with a single tooth. Tooth very broad; long; deltoid. Apex broadly rounded. 

 Detached AXCu fragment large; broad; moderately sclerotized. 



Tail long; aciculate; dorsal surface is recurved. Dorsal surface oriented laterad. Anterior 

 section only weakly convex. Median and posterior section very weakly convex to flat. 

 Window absent. Distal margin straight. FJ and AXJ equally broad; moderately strongly 

 sclerotized. Suture line present. AXA occupies an equal amount of the tail as FJ+AXJ; 

 straight. Suture line between FJ+AXJ and AXA present. Suture line between AXA and 

 AXCu strong.

First Basal Plate (Fig.49) 



Humeral Plate moderately broad and short. Anterior margin sinuate. Apex broadly rounded: 

 curved ventrad. Dorsal margin convex; distant from BScA. Distal margin reduced. Ventral
