Strophiops (Umbonis) aspera Maynard & Clapp in Maynard, 1920

Original Description

Maynard (1919a:14) first used the binomen S. aspera as a nomen nudum.  He again used this taxon name as an example of sand gathering (Maynard, 1920a:77) and elongated (Maynard, 1920b:89) phenotypes, in each instance citing an illustration of the shell (Maynard, 1920b:fig. 57).  A colored version of this illustration appeared in Maynard (1920b:pl. 12, fig. 1). Both illustrations were published with the caption "S. aspera M & C." The usage in Maynard (1920a:77) is also 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 aspera Maynard and Clapp in Maynard, 1920b: fig. 57, pl. 12, fig. 1 available (Article 12.2.7, ICZN, 1999:17) prior to the intended description of this species (Maynard and Clapp in Maynard, 1920d:116; Map 1, 4;  Plate 1, figs. 9,10).  Due to Maynard's unintended taxonomic act, the binomen Strophiops aspera becomes available on April 8, 1920, but retained the same authorship.
