margins of the distal lobe; indistinct from lobe; short; narrow. Median section convex. 

 Subalare tendon attachment point moderately long and narrow; extends posteriad from the 

 median; not curved ventrad; weakly visible dorsally. Posterior margin rounded. 



Body - Dorsal view: Proximal lobe short; narrow; deltoid; arises postero-medially from 

 ridge; moderately sclerotized; flat; depressed below the ridge; oriented proximad. Base 

 weakly enlarged. Anterior and posterior margins greatly enlarged; concave. Apex narrowly 

 rounded; curved anteriad. Distal lobe large and broad; roundly deltoid; not reduced distally; 

 much larger than proximal lobe; weakly sclerotized; convex; slopes strongly ventrad from 

 the ridge giving the appearance that the distal ridge and lobe are curving and twisting 

 around the proximal ridge and lobe. Base very broad. Apex broadly rounded. Anterior 

 margin normal length; weakly concave. Posterior margin weakly concave. - Ventral view: 

 Proximal lobe narrow and long; weakly convex. Posterior wing process junction ovoid; 

 occupies the posterior margin of the lobe. Distal lobe weakly concave; continuous with 

 ridge; planate. 



Median Plate (Fig.40) 



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

 rectangular. Anterior, median and posterior sections 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 broadly 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.41) 



Head narrow; normal length; weakly convex. Proximal margin straight. Anterior margin 

 narrow; not enlarged ventrally; weakly convex. FCu normal size. Distal margin strongly 

 reduced by FA and AXCu. FA broad; weakly sclerotized; only visible laterally. AXCu 

 large; occupies half of the head. Anterior margin enlarged 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 very weakly elevated dorsad. FCu section of neck absent. Neck comprised of AXCu. 

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

 present. Prong armed with a single tooth. Tooth short; weakly deltoid. Apex moderately 

 broadly rounded. Detached AXCu fragment very small; slender; weakly sclerotized. 



Tail long; aciculate; convex. Dorsal surface oriented laterad. Anterior only weakly convex. 

 Median and posterior very weakly convex to planate. Window absent. FJ and AXJ equally 

 broad; moderately strongly sclerotized. Suture line present. FJ occupies an equal amount 

 of the tail as FJ+AXJ. AXA moderately long; straight. Suture line between FJ+AXJ and 

 AXA present. Suture line between AXA and AXCu strong.
