(Figs. 2 and 3)
Diagnosis. Females of this species are similar to Augochlorella una and can be separated from the remaining Augochlorella by the olive green head and mesosoma (not olive in other species), elongate head (wider than longer in other species), and microreticulate posterior and lateral surfaces of the propodeum (not microreticulatein otherspecies) (Fig.2). From A.una, the newspecies can be separated bythemetapostnotumwith strongposteriormarginal angles, being almost trapezoidal (Fig. 2C), preoccipital ridge carinate, mesoscutum punctures sparser on the median surface (interspaces equal to one puncture diameter on A. una, and about two puncture diameter on A. kelliae sp. nov.) and the scutellar punctures are not strong and contiguous. The male can be separated from other species by the combination of clypeus with a transverse yellow band, hind leg with short setae, preoccipital ridge carinate, and metapostnotal carinae almost reaching the posterior margin (Fig. 3).

Comments. Coelho (2004) listeda A.una paratype femaleas “1?m#, Minas Gerais, Serra da Moeda, Zona Metalúrgica, 15.x.1997 (E. A. B. Almeida) (BHMH)”, the author listed all specimens of A. una with male symbols but the species is only known from females. As the question mark could represent a dubious identification Ispeculate that this paratype can be a specimen of A. kelliae sp. nov. In this case A. una is known only from Central Brazil and A. kelliae sp. nov. is known only for Minas Gerais.
Type material. Holotype female (DZUP): “ Brasil, Minas Gerais,\ São Tomé das letras,\ 21 43S, 44 58W \ 12.I.2010, K. Ramos \ and V. Kanamura ”. Paratypes: three females (DZUP) with same data of holotype; two females (DZUP) “Brasil, Minas Gerais, Serra do Cipó, X.2018, Leticia Graf leg.”; one male (UFMG) “Abelhas de Canga\ Parque Estadual da\ Serra do Rola–Moça\ 25745–75506” “Nova Lima MG\ BRASIL 14/03/2013 \ J.E. Santos Jr”.
Etymology. In honor of Dr. Kelli S. Ramos, friend, melittologist, and collector of the type.
