Mimuloria dilatata sigmoidea , new subspecies

Fig. 20–21 .

Type specimen. Male holotype ( NCSM) collected by R. M. Shelley and W. B. Jones, 14 October 1978, ca. 7.2 km (11.5 mi) S Decatur, along county road 4274, 0.8 km (0.5 mi) from junction of Tennessee highway 58, Meigs Co., Tennessee.

Diagnosis. Acropodital lobe broad, well defined, and distinct; prefemoral process with basal shoulder/ flange on dorsal surface, configuration broadly sigmoidal, curving strongly inward into acropodital arc and then outward, terminating near level of latter’s tip ( Fig. 20–21 ).

Etymology. The subspecific name denotes the overall sigmoidal curvature of the prefemoral process, which also passes through numerous vertical planes.

Distribution. Known only from the type locality, in the Tennessee River Valley on the east side of the river itself.
