9334EE02FFB9FFD0E5F3F983244FCC0B.taxon	etymology	Etymology: From Latin avus = ancestor / grandfather, in reference to the species basal position within its clade, according to phylogenomic data. Fittingly, the name also honors the first author’s grandfather, whose love for nature was always a source of admiration and inspiration. The name is applied here as a noun in apposition.	en	Camacho, Gabriela P., Franco, Weslly, Feitosa, Rodrigo M.

9334EE02FFB9FFD0E5F3F983244FCC0B.taxon	discussion	Comments: Gnamptogenys avus is similar to G. mina (Brown). Gnamptogenys avus has compound eyes (only one ommatidium in G. mina), the scape surpasses the vertex margin (not reaching the vertex margin in G. mina), and the propodeal spiracle is protruding (less protruding in G. mina). Despite the morphological similarities between G. mina and G. avus, both species do not appear to be closely related, according to phylogenomic analysis of Gnamptogenys species relationships (Camacho et al., in prep).	en	Camacho, Gabriela P., Franco, Weslly, Feitosa, Rodrigo M.

9334EE02FFBAFFCFE5F3FE332224CF77.taxon	discussion	Comments: The width and number of costulae on mesosoma and the propodeal spiracle positioned at the lateral margins of the propodeum are enough to distinguish Gnamptogenys latistriata from any other of its closely related species. The species is very similar to G. strigata, a commonly collected species of wet montane transandean forests, that occurs throughout Central America, from Mexico to Colombia. Although Antmaps. org (Janicki et al. 2016) lists Kempf (1972) as a reference for the occurrence of G. strigata in Brazil and Paraguay, Kempf (1972) does not record the species for those countries. G. strigata was not found to occur in Brazil during this revision or previous revisions (Brown 1958; Lattke 1995). Gnamptogenys latistriata differs from G. strigata by its flat vertex margin and propodeum dorsum not depressed in relation to mesonotal dorsum. Aside from these differences and to the great geographic distance between the records of both forms, phylogenomic analysis revealed that G. latistriata represents a distinct lineage within Gnamptogenys, not closely related to G. strigata (Camacho et al., in prep).	en	Camacho, Gabriela P., Franco, Weslly, Feitosa, Rodrigo M.

9334EE02FFA4FFCBE5F3FF3C26AFCC9B.taxon	biology_ecology	Natural history: Data on the natural history of this species is based on information from labels and reports of collectors. The species is usually found in the leaf litter of Atlantic Forest regions. Two of the specimens examined were collected in coffee plantations in Minas Gerais, but there is no information on whether the plantations were conventional or agroforestry. The latter is common in the area where the specimens were collected and would provide a more sheltered environment than conventional production. Two records were recently made for the species, one in a Winkler extraction of a layer of five centimeters deep bare soil, also in Minas Gerais, and in a sample from a rotten tree trunk on the forest ground (Júlio Chaul, personal communication). Another collection in the same region revealed individuals of the species in hypogaeic pitfall traps, 25 cm deep (Rodrigo Jesus, personal communication). These records and the small eyes suggest a partially hypogaeic habit. Gnamptogenys lavra was also recorded by one of the authors (RMF) in submontane forests in Rio Grande do Sul during a cold snap, suggesting these ants can tolerate lower temperatures.	en	Camacho, Gabriela P., Franco, Weslly, Feitosa, Rodrigo M.

9334EE02FFA4FFCBE5F3FF3C26AFCC9B.taxon	discussion	Comments: This species is morphologically related to G. reichenspergeri (Santschi) and can be differentiated by the abundant and conspicuous sculpture on the mesosoma, without smooth and shiny areas, and also by the smooth and shiny mandible surface. Additionally, the frontal sculpture of the head is more uniform than in G. reichenspergeri, with parallel costulae. Gnamptogenys lenis, described here, has similar features, but differs from G. lavra by the gaster being completely smooth and shiny and the scape surpassing the vertex margin.	en	Camacho, Gabriela P., Franco, Weslly, Feitosa, Rodrigo M.

The wide and patchy distribution might suggest that many records can still be found. In fact, since the species was synony- mized under G. striatula by Brown (1958), many records of G. striatula might actually be G. pernambucana.	en	Camacho, Gabriela P., Franco, Weslly, Feitosa, Rodrigo M.

9334EE02FFA3FFC6E5F3FEC02461C8D7.taxon	biology_ecology	Natural History: Little is known about the biology of G. pernambucana, but label information shows that this species is usually collected in areas of open vegetation such as the arboreal Caatinga, Canga and open grasslands, with at least one record also in the wetlands of Pantanal. Most of the collected specimens were sampled with soil baits of sardine and honey and, sometimes, with pitfall traps, suggesting that the species usually forages on the ground.	en	Camacho, Gabriela P., Franco, Weslly, Feitosa, Rodrigo M.

9334EE02FFA3FFC6E5F3FEC02461C8D7.taxon	discussion	Comments: This species, previously synonymized with G. striatula, is distinguishable from the latter by the aforementioned diagnostic characters. However, measurements and proportions of the scape in relation to the head are the principal means of distinguishing between the two species. Although the differences between this species and G. striatula are not striking, they seem consistent enough to define different species, especially since they occur in sympatry. During this revision, we were able to identify both G. striatula and G. pernambucana in the same area of the Parque Estadual de Vila Velha, Paraná, Brazil, the first one occurring in forest areas and the second one only in open field areas, with clear morphological differences. Additionally, a phylogenomic analysis of 2,500 ultra-conserved elements across 322 Gnamptogenys species supports our hypothesis that this is a separate lineage, recovering G. pernambucana as sister to G. moelleri (Camacho et al., in prep).	en	Camacho, Gabriela P., Franco, Weslly, Feitosa, Rodrigo M.
