Material examined

Panama, Coiba National Park . Holotype: MNCN 16.01 About MNCN / 8880a, Granito de Oro Island. 7 ° 359300 N, 81 ° 429300 W, 2 m. Paratypes: MNCN 16.01 About MNCN / 8880b, same locality; MNCN 16.01 About MNCN / 8882, Rosario Beach , Coiba Island, 7 ° 389300 N, 81 ° 419400 W, 2.5 m; MNCN 16.01 About MNCN / 8883, Ensenada Maria , Coiba Island, 7 ° 249200 N, 81 ° 419 W, 6 m. The paratype MNCN 16.01 About MNCN / 8881, Canal de Afuera Island , 7 ° 419500 N, 81 ° 389250 W, 4 m, is now on a stub for SEM in the Australian Museum ( AM W30487) .

Remarks

In the original description some important features were not described. Large ventral basal flanges extending posteriorly to the posterior peristomial ring are present ( Figure 10A View Figure 10 ). Anterior peristomial ring (though only visible on one side in Figure 10A View Figure 10 ) is of even height all around (see Capa and López 2004). Posterior peristomial ring is low and not projected ventrally ( Figure 10A View Figure 10 ). In the cladistic results provided here, this species forms a clade with A. bondi sp. nov. A. magna sp. nov., A. lenae sp. nov., and A. nathae based on the number of pinnules in radioles and the small size of the dorsal radiolar appendages.
