Ridges - Dorsal view: Proximal ridge entire; distinct from lobe. Anterior to antero-median 

 section partially concealed by the distal ridge. Antero-median to postero-median section 

 strongly elevated above the distal ridge; demarcated from body by an impression. Posterior 

 section moderately enlarged above the dorso-distal ridge; extremely long; not incorporated 

 into lobe; distinct from lobe and extremely strongly extended past the posterior margin of 

 lobe; extends posteriad from the median. Distal ridge weakly distinct from lobe. Apex 

 oriented ventro-proximad; convex and broadly falcate; moderately short. Anterior section 

 moderately short; curved proximad. Median to posterior section extends below the 

 proximal ridge; very weakly demarcated from body by an impression. Posterior section 

 strongly acerose; weakly extended past the posterior margin of lobe. - Ventral view: 

 Proximal ridge broad; moderately long; straight; distinct from lobe. Apex aciculate. 

 Anterior to antero-median section digitate; broad; obscures distal ridge except the apex. 

 Median to posterior section obscured by the distal ridge. Distal ridge broad but short. 

 Apex narrow. Anterior to median section concealed by the proximal ridge. Median and 

 posterior sections arise from the proximal and posterior margins of the distal lobe; distinct 

 from lobe; slender. Median section concave. Postero-median section convex and waisted. 

 Subalare tendon attachment point extremely long and slender; apically not curved ventrad; 

 posterior margin rounded; extends posteriad from the median; strongly visible dorsally. 



Body - Dorsal view: about as long as broad. Proximal lobe oriented proximad; arises from 

 the postero-medial section of the ridge, depressed below the ridge; strikingly small; deltoid; 

 strongly sclerotized; convex. Posterior margin weakly enlarged; concave. Base extremely 

 narrow. Apex narrowly rounded; very weakly curved anteriad. Distal lobe moderately long 

 and broad; roundly deltoid; larger than proximal lobe; moderately sclerotized; markedly 

 convex. Anterior margin normal length; straight. Apex narrowly rounded. Posterior margin 

 very weakly concave; reduced. - Ventral view: Proximal lobe extremely small; only the 

 apex is visible; convex. Posterior wing process junction obscures most of the proximal 

 lobe; formed as a prominent ovoid convexity which extends anteriorly from the posterior 

 margin of the distal ridge. Base ridge-like; convex. Apex small; ovoid. Distal lobe 

 discontinuous with ridge; weakly concave. 



Median Plate (Fig.61) 



FM1 oriented strongly postero-distad. Anterior to posterior section very broad. Proximal 

 margin convex. Articulation with 2Ax extends along the entire margin of the distal lobe 

 over the posterior section of the ventral ridge. Distal margin fused to the proximal margin 

 of 3Ax from the antero-distal corner to just anterior to the neck of 3Ax. FM2 very short; 

 oriented posteriad; acerose; separated from FM1 by a long slender section of membrane. 



Third Axillary (Fig.62) 



Head strikingly convex; moderately broad; normal length. Proximal margin straight. 

 Anterior margin weakly convex; not enlarged ventrally. Antero-proximal margin rounded; 

 very weakly cleft. Antero-distal margin rounded. FCu normal size; distinct; ovoid. FA 

 narrow; short; displaced anteriorly by FCu. AXCu does not form part of the head. Suture
