1 "Specific and subspecific names are subject to the same rules and recom- 

 mendations, and from a nomenclatorial standpoint they are coordinate 

 that is, they are of the same value." (Article 11, International Code.) 

 Euthrips ulicis californicus and E. triciti californicus, though both originally 

 described as varieties, were written as trinomials, and thus brought with- 

 in the scope of the above rule. The Entomological Code is more sweeping, 

 specifying in Section 37 that, "In species, subspecies, varieties, or races, 

 the same name shall not be used twice in the same genus."
