strongly expanded anteriorly and distally. Distal margin very weakly convex. Apex very 

 weakly curved ventrad and posteriad; aciculate. - Ventral view: Proximal arch margined 

 by a broad ridge. Posterior margin with a long ridge; entire but weak. Distal margin with 

 a broad ridge. 



Second Axillary (Fig. 25) 



Radial Fulcalare moderately broad. Terminus fused to the 2Ax ridge-body junction. Point 

 of fusion moderately broad; weakly extended along the anterior margin of 2Ax. 



Ridges - Dorsal view: Proximal ridge entire; weakly distinct from lobe. Apex narrow. 

 Anterior section partially concealed by the distal ridge. Ant ero -median to postero-median 

 section extremely narrow; partially enlarged above the distal ridge. Posterior section 

 strikingly enlarged above the distal ridge; oriented posteriad. Apex narrow. Distal ridge 

 very weakly distinct from lobe. Apex narrow but broadly falcate; convex; moderately short; 

 oriented ventro-proximad; not fused to the proximal ridge apex. Anterior section 

 moderately short; moderately narrow; strongly curved proximad. Median to posterior 

 section slender; oriented posteriad. - Ventral view: Proximal ridge moderately narrow; 

 distinct from lobe. Anterior to median section conceals the proximal section of the distal 

 ridge; curved proximad. Postero-median to posterior section partially obscured by the 

 distal ridge; visible proximally as a slender, concave piece. Distal ridge moderately broad; 

 very long. Postero-median to posterior section rectangular; moderately broad. Proximal 

 and posterior sections arise from the posterior margin of the distal lobe. Subalare tendon 

 attachment point extends posteriad from the median; strikingly lengthened; slender. 



Body - Dorsal view: about as long as broad. Proximal lobe small; deltoid; arises antero- 

 medially from ridge but depressed below the ridge; strongly sclerotized; convex; oriented 

 proximad. Base very narrow. Apex truncate; weakly curved anteriad. Anterior margin 

 deeply concave. Posterior margin weakly concave; weakly enlarged. Distal lobe strikingly 

 reduced posteriorly and apically; longer and broader than the proximal lobe; strongly 

 sclerotized; weakly concave; arises from the extreme anterior section of the ridge. 

 Proximal half v try thick; strongly sclerotized. Distal half thin; strongly sclerotized; weakly 

 concave. Anterior margin strongly sclerotized; weakly sinuate; normal length. Base broad. 

 Apex reduced; rounded. Posterior margin concave; reduced. - Ventral view: Proximal lobe 

 partially concealed by the distal ridge; slender; cylindrical; convex; distinct from proximal 

 ridge; oriented weakly antero-proximad. Posterior wing process junction weakly ovoid; 

 occupies the posterior margin of the lobe. Base narrow. Apex round. Distal lobe deltoid; 

 flat; small; distinct from distal ridge. 



Median Plate (Fig.26) 



FM1 large. Anterior section very narrow. Antero-median section abruptly broad. Antero- 

 distal margin fused with FM2; a small membranous gap separates the two anteriorly. 

 Proximal margin broadly fused with 2Ax from a point just posterior of the apex to the 

 terminus. Distal margin broadly fused to 3Ax along the antero-proximal margin to the 

 median. FM2 weakly distinct from FM1; short; deltoid.
