A revision of the (Brues) species subgroup of the species group with the descriptions of 18 new species from the Neotropical Region.

The (Brues) species subgroup of the species group is defined based on two previously described species, and (Enderlein), and is greatly expanded in this paper with an identification key, descriptions, and illustrations of 18 new species from the Neotropical Region: Shaw & Shimbori, ; Shimbori & Shaw, ; Shimbori & Shaw, ; Shimbori & Shaw, ; Shimbori & Shaw, .; Shimbori & Shaw, ; Shimbori & Shaw, ; Shimbori & Shaw, .; Shaw & Shimbori, ; Shimbori & Shaw, ; Shimbori & Shaw, ; Shimbori & Shaw, ; Shimbori & Shaw, ; Shimbori & Shaw, ; Shimbori & Shaw, ; Shimbori & Shaw, ; Shaw & Shimbori, ; and Shimbori & Penteado-Dias, It is hypothesized that the species subgroup is a monophyletic lineage within the larger and probably artificial species group (those with a comb of flat setae at the apex of the hind tibia), and can be distinguished from other members of the group by having the hind wing vein r present, although weakly indicated; the hind wing marginal cell suddenly widened at junction of veins RS and r; the subbasal cell of the fore wing mostly glabrous but often with two rows of short setae subapically; glabrous regions of the wings also commonly found in the first subdiscal, discal, and basal cells of the fore wing, and the basal cell of hind wing; ocelli quite large, with the width of a lateral ocellus being distinctly larger than the ocellar-ocular distance; and being relatively large species with body almost entirely brownish yellow or reddish brown. In addition, a new replacement name, Shimbori & Shaw, , is proposed for the species formerly called Aleiodes (Hemigyroneuron) bakeri Butcher & Quicke, 2011.
