Members of this group can be identified by the following combination of characters: head generally dome-shaped, but may have slightly flattened frons, never extended anteriorly as in  Guimaraesiella papuana (Giebel, 1879) (Gustafsson &amp; Bush, 2017, fig. 356); dorsal anterior plate continuous posteriorly with main head plate; antennae sexually monomorphic; female subgenital plate with at least partial cross-piece, often submarginal in lateral ends; male genitalia typical for  Guimaraesiella (see Gustafsson &amp; Bush 2017, figs 6–10, 358), without rugose nodi or thickenings on the mesosomal lobes, but also without a ventral sclerite. Most of the species in this group occur on thraupid hosts.</p><p>The  “ interposita species group” includes at least the following species:  Guimaraesiella interposita (Kellogg, 1899),  G. melanococa (Carriker, 1903),  G. ptiliogonis (Carriker, 1903),  G. abbasi (Carriker, 1956),  G. rhamphocelii (Cicchino, 1983),  G. schistacea (Cicchino, 1983) and  G. atricapilla (Cicchino, 1983) .  Guimaraesiella taulis (Eichler [in Niethammer], 1956) probably belongs to this group as well, but the only known female is too poorly preserved to confirm its status.  Guimaraesiella granatensis (Soler-Cruz, Rodríguez, Florido-Navío &amp; Muñoz-Parra, 1987) may also belong to this group, but we have not examined any material of this species, and the original species description is not detailed enough to determine its position. However, not all  Guimaraesiella from thraupid hosts belong to the  interposita group. For instance,  Guimaraesiella cubana (Cicchino, 1983) does not belong to this group, but to a group of  Guimaraesiella more commonly found on mimid hosts.</p><p>Since there was no species of the  Guimaraesiella interposita species group included in the phylogeny of the  Brueelia -complex by Bush et al. (2016), its position within  Guimaraesiella is unknown. The species in the group are similar to the “core  Guimaraesiella ” (sensu Gustafsson et al. 2019), and many species are superficially similar to species of  Guimaraesiella found on thrushes ( Turdidae). Notably, both species described here lack the anterior extension of the ventral sclerite in the male mesosome that is characteristic of the “core  Guimaraesiella ”.</p></div>	https://treatment.plazi.org/id/03D087C9FFDAFFEF83CAAB0BED7212F3	Public Domain	No known copyright restrictions apply.

The only other member of the  Guimaraesiella interposita species group in which the dorsal preantennal suture does not reach the ads is  G. aedon sp. nov. Guimaraesiella inaccessibilis can be separated from  G. aedon by the following characters: head proportionately longer and broader in  G. inaccessibilis (Fig. 4) than in  G. aedon (Fig. 5); proximal mesosome about as long as broad in  G. inaccessibilis (Fig. 6), but broader than long in  G. aedon (Fig. 9); mesosomal lobes with lateral ridge in  G. aedon (Fig. 10), but no such ridge present in  G. inaccessibilis (Fig. 7); abdomen of  G. inaccessibilis with even yellow pigmentation, but abdomen on  G. aedon with medium-brown pigmentation of sternal and subgenital plates, and dark-brown pigmentation on lateral sections of tergopleurites.</p><p>Description</p><p>Male. Head flat-dome shaped (Fig. 4), frons slightly flattened, lateral margins of preantennal area convex. Dorsal preantennal suture reaches dsms but does not reach ads or lateral margins of head.
