Pteronymia tucuna (H. Bates, 1862)

Figure 10

Females examined: 3. 1 with complete sphragis; 2 bearing incomplete or amorphous sphragides.

Description: Coloration—golden-brown. Structure—mostly solid. Shape—somewhat posteriorly bilobed roughly following the bilobed shape of sterigma. Surface textured with a medial cavity.

Scales—male scales orderly and attached to the anterior edge of the sphragis. Complexity category—3.

Comments: The anterior portion of the sphragis is protruding to the outside of the sterigma. We are uncertain if the protrusion of the anterior part of the sphragis is a common feature of this sphragis, but it is likely that this sphragis was dislocated from its original position.
