Bartley, 1993a [BAR93A]. May be the same as MIRANDA in Soria, 1970a [SOR70A].

In previous versions of the ICGD the SPA [COL] clones were included as synonyms of the group SC [COL] (SC 57 - 76 inclusive). The synonymy has now been reversed as this material was originally described as SPA and is more widely known under this name, as advised by Dr. Bartley.
