The binomen Strophiops caduca was first used as a nomen nudum (Maynard, 1919b:35). Maynard (1920a:77) again used this binomen together with a reference to a subsequently published illustration (Maynard, 1920b:fig. 56, captioned "S. caduca M. & C.") as an example of a specimen with depressions in its surface sculpture. The use of the name in Maynard (1920a:77) is a nomen nudum. The association of a new species group name with an illustration of the taxon being named prior to 1930 made the name Strophiops caduca Maynard and Clapp in Maynard 1920b: fig. 56 available (Article 12.2.7, ICZN, 1999:17) prior to the intended description of this species (Maynard and Clapp in Maynard, 1921a:133, Plate 30, figs. 9, 10). Due to Maynard's unintended taxonomic act, the binomen Strophiops caduca became available on
