Maybe Mexican... it's an off-shoot dialect of Castilian, but not necessarily named.

While all Spanish dialects use the same written standard, there are important variations spoken among the regions of Spain and throughout Spanish-speaking America. One major phonological difference between
Castilian, broadly speaking, the dialects spoken in northern Spain, and the dialects of southern Spain and all the Latin American dialects of Spanish, is the absence of a
voiceless dental fricative (/θ/ as in English
thing) in the latter.
[34] In Spain, the Castilian dialect is commonly regarded as the standard variety used on radio and television,
[35][36][37][38], although attitudes towards southern dialects have changed significantly in the last 50 years. In addition to variations in pronunciation, minor lexical and grammatical differences exist. For example,
loísmo is the use of slightly different pronouns and differs from the standard.
The variety with the most speakers is
Mexican Spanish, spoken by about a fourth of Spanish speakers.[/QUOTE]
