Key to the species of Agapostemonoides

1. Occipital carina low throughout, not lamellate dorsally; punctation on lateral portions of disc of T1 sparser. Female: mesoscutal pubescence long, on anterior corners distinctly longer than one ocellar diameter; terga completely dull ( Fig. 1 ); pubescence on basal half of T1 well developed ( Fig. 1 ). Male: pubescence dark brown on scutellum and metanotum; legs black; sterna 7 and 8 as in Fig. 8 . Costa Rica and Panama ( Fig. 18 ) ................................................................................................. Agapostemonoides hurdi

­ Dorsal portion of occipital carina distinctly lamellate ( Fig. 3 ); punctation on lateral portions of disc of T1 denser ( Fig. 2 ). Female: mesoscutal pubescence short, on anterior corners subequal to one ocellar diameter; terga reflective, with only a dull luster ( Fig. 2 ); pubescence on basal half of T1 relatively sparse. Male: pubescence light brown on scutellum and metanotum; legs dark brown to amber; sterna 7 and 8 as in Fig. 9 . Bolivia and Peru ( Fig. 18 ) ....................... Agapostemonoides weirauchi sp. nov.
