In zoology, "monospecific" is an adjective describing a genus which contains only one known species. The term comes from the Greek prefix "μονο-" meaning "single" and Latin "species" meaning "kind" or "type". It is thus of hybrid origin. In botany, "monotypic" or "unispecific" are used instead of "monospecificity" to refer to a taxon (at any rank) that includes only one species. "Monotypic" is also used in zoology, but with a different meaning.
