Taxonomy and systematics

The first description by a European ornithologist of a falconet from this group was published by George Edwards in 1750, as "the little black and orange colour'd Indian hawk". It was from a specimen that had been collected in Bengal and sent to the King's physician, Dr Mead. In 1758

Carl Linnaeus Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming o ...

that is now called the collared falconet. In 1824, Vigors proposed a new genus ''Ierax'', writing "whoever has seen that beautiful species, the smallest of its race, ''F. cærulescens'', Linn., now rendered familiar to us by the accurate and splendid illustrations of Dr. Horsfield, will at once acknowledge its separation from every other established genus of its family." Later authors rendered the name ''Hierax''. Sharpe coined the name ''Microhierax'' in 1874, from the Greek meaning "tiny hawk". By this time, four species were known: ''M. cærulescens'', ''M. fringillarius'', ''M. melanoleucos'', and ''M. erythrogenys''. He lists Horsfield's specimen "''Falco cærulescens''" as being actually ''M. fringillarius'', making the latter the type of the genus. A fifth species, the white-fronted falconet ''M. latifrons'', was described by Sharpe in 1879.Pag
