Augochloropsis (Glyptochlora) ornata ( Smith, 1879)

( Figs. 1B–C ; 2C–D; 2I ; 4B ; 5 )

Megalopta ornata Smith 1879: 49 . Holotype female, Brazil: Amazonas, São Paulo de Olivença (NHMUK, examined from photographs).

Diagnosis. This species can be separated from the remaining A. ( Glyptochlora ) by the green body coloration in combination with a red lower parocular area (blue body coloration with green lower parocular area in A. atrocyanea sp. nov. and coppery body coloration with red lower parocular area in A. peruviana sp. nov. and A. ticuna sp. nov.); mesepisternum with inconspicuous dark setae; propodeum with the most basal margin of the lateral expansions concave and continuous with the margin of the expansion in the distal region; anterior margin of T1 not leveled with dorso-lateral line level, therefore dorsolateral line slightly elevated; open coarse punctures on lateral surfaces and whitish body pubescence.

Comments. Only found in Amazonian localities in Brazil (Mato Grosso and Amazonas) and the slopes of the Andean cordilleras in Peru (Cusco) .
