Etymology: < French monotype (see monotype n.) + -ic suffix. Compare slightly earlier monotypous adj.

1858 C. Darwin Let. 4 Mar. in Corr. (1991) VII. 42 My impression would have been..that monotypic forms were more interesting.

1886 P. L. Sclater Catal. Birds Brit. Mus. XI. 17 Hemidacnis... This is again a monotypic form.

1987 Internat. Jrnl. Systematic Bacteriol. 37 365 Spiroplasma strain AES-1, which was isolated from the salt marsh mosquito Aedes sollicitans, is the monotypic representative of group X.

b. Of a genus or higher taxon: containing only one species. Later also, of a species: having no constituent subspecies or varieties.

1909 Science 4 June 914/1 The rule adopted by the international zoologists and the American botanists that a monotypic genus must always contain its monotype appears to receive no particular recognition.

1940 J. S. Huxley New Systematics 10 Rensch has proposed the term Rassenkreis for a group of subspecies which replace each other geographically. In order to conform to accepted usage and to terms of international applicability, it is perhaps better to call such groups polytypic species, in contradistinction to the monotypic species..which show no subspeciation.
