Diagnosis. Augochlora mulleri is a relatively large-sized species, with very coarse body punctation. Females have the mid trochanter ventral margin strongly projected (Fig. 1G), as A. atlantica sp. nov., but can be identified by the strongly inflexed T1 apex, forming a tubular margin and by the body color, which is usually entirely green with blue iridescence. Males can be diagnosed also by the T1 tubular border and by the T2 disc protuberant. Overall appearance of metasomal terga resembles bees of the cleptoparasitic genus Temnosoma Smith.
Comments. We did not examine the type material of A. mulleri but the original description mentions diagnostic features for the species, including coarse and contiguous punctation, along with the long spiniform projection on S1. Previous authors recognized this species and proposed those synonymies (Moure & Hurd 1987). A nest of this species was observed in rotten wood by Sakagami & Moure (1967).
