Xenochlora Engel, Brooks & Yanega, 1997: 7 . Type species Xenochlora ochrosterna Engel, Brooks & Yanega, 1997 .

Comments. According to Engel (2000) and Michener (2000, 2007), Xenochlora differs from Megalopta in the non enlarged ocelli, hamuli in series broken by gaps (as in most other Augochlorini ), some hooks thus isolated, and hind tibia and basitarsus largely covered with black setae. Adittionaly Xenochlora differs from Megalopta by: male S3 with digitiform apical lobes ( Fig. 13 ); S4 lacking stiff setae along mid longitudinal sulcus ( Fig. 14 ); apical margin of S5 with broad mid emargination and sinuous lateroapical margin ( Fig.15 ); ventral parapenial lobe narrow along most of its length, its apex only weakly expanded ( Fig. 17 ).
