Taxa of the generally "blue-above" Calywpis and Tergissima and Femniterga, new genera, are de- "brown-above" Calyst yma have extremely similar under scribed from hitherto seldom sampled localities of 500- surface wing patterns (see Field, 1967a, p. 1; 196% p. 2) 1700 m. altitude in Salta, Jujuy and Tucuman provinces, a feature also shared with several little-studied groups of Argentina. The new genera are allied to New World the broadly polyphyletic Theclinae grade "Thecla" (sensu Calycopis and Neotropical Calystryma, but differ from the Bridges, 1986). These latter include the "vesulus group" generic characters of these in having extreme termino- of Draudt (1919) (e.g., T. vesulus Cramer and T. anthora ventrad development of the incised posterior cavity of Hewitson), or Draudt's "badaca group" (e.g. T. autoclea the eighth abdominal tergite (Tergissima males, Fem- Hewitson [=sangala Hewitson] ).
