Etymology: < ancient Greek -πτερος, combining form (in e.g. ϕοινικόπτερος red-feathered: see phoenicopter n.) of πτερόν wing (see ptero- comb. form) + -ous suffix.Combined with first elements ultimately of Greek origin. Earliest attested in the 18th cent. in words modelled on ancient Greek or Hellenistic Greek compounds, or on post-classical Latin or scientific Latin words in -pterus , -ptera , as apterous adj., dipterous adj. Formations within English are found from the 19th cent. In connection with the Latin names of insect orders in -ptera , words in -pterous have been mostly displaced in technical use by words in -pteran (as dipteran adj.).
