"Monobasic" certainly is (or was) also used in taxonomy, but perhaps not so much now, and any Google search only turns up the chemistry meaning.

From what I understand, monobasic
is a term used in chemistry while monotypic is a term used
in taxonomy and nomenclature. Definitions of both terms are
available in good dictionaries or even on the web.

is a nomenclatural term (ICZN) in relation to the fixation
of a type species of a new genus, but the grammatical
variant monotypic has broader meaning. It is perhaps ugly to
have variants of the same term with different meanings (one
broader than the other)!
