of Micromelo undatus (Bruguière, 1792) [Bulla], which is according to the recent publication (published online 27 July 2021) by Feliciano et al. (2021) an Atlantic Ocean species, reported from the Western Atlantic Ocean from Brazil to Florida, USA, and from the Eastern Atlantic Ocean from the Cape Verde Islands to the Tenerife Island, Spain.
Feliciano et al. (2021) described the specimens from the Philippines and other locations as
Micromelo barbarae Feliciano, Malaquias, Stout, Brenzinger, Gosliner & Valdés, 2021, which is characterized by the colour of the body margins "yellow-orange band followed inwards by pale green diffuse band" and "large, oval or compound opaque white patches, widely spaced; distance between patches equal or larger than patches themselves."Feliciano et al. (2021)
but in the Western Indo Pacific occurs also Micromelo guamensis (Quoy & Gaimard, 1825) [Bullaea], which differs by a light vibrant blue band followed inwards by dark blue or purple diffuse band", and by "large, compound opaque white patches, densely arranged, almost touching; distance between patches smaller than patches themselves."
This species was posted on on 11 May 2004 at these websites as Micromelo undata (Bruguière, 1792) [Bulla], and changed on 10 February 2021
into Micromelo undatus (Bruguière, 1792) [Bulla].
The genus Micromelo Pilsbry, 1895 is in older publications placed in the Order Cephalaspidea, according to Bouchet & Rocroi (2005) are
the superfamilies: Acteonoidea and Ringiculoidea no more in the Order Cephalaspidea in the Subclass: OPISTHOBRANCHIA, but
in the new informal group Lower Heterobranchia (= Allogastropoda) Haszprunar, 1985.
