0398BF12FFECFFACFF6F8315FEFF1E4E.taxon	etymology	Etymology. The species name is a nominative feminine singular of the Latin academicus, which refers to an academic or academician. This name was chosen in recognition of the type locality being within the Campus Politécnico of the Federal University of Paraná.	en	López-Muñoz, Román A., Villarreal, Erick, Lattke, John E. (2018): Two new species of Leptogenys from southern Brazil (Hymenoptera: Formicidae). Zootaxa 4410 (3): 559-566, DOI: 10.11646/zootaxa.4410.3.9
0398BF12FFECFFACFF6F8315FEFF1E4E.taxon	discussion	Discussion. Leptogenys academica fits into the crudelis group of species (Lattke 2011) with the exception of having a scrobiculate metanotal sulcus. This fair-sized species will key without difficulties to couplet 37 in Lattke (2011), whereupon the reader may use the modification to the key provided below. The anteromedial eye margin of all the studied specimens of L. academica have the ommatidia along rows 1 – 3 black, contrasting with grey-silver color of the rest of the eye, giving it a more elongate appearance upon first glance. This feature was not considered in the description as it could be an artifact. This species was found during a series of pitfall sampling campaigns in a patch of forest next to the Zoology Department on the Campus Politécnico of the Universidade Federal do Paraná, within the metropolitan area of the city of Curitiba. The vegetation in the reserve is mostly secondary forest with emergent Araucaria angustifolia (Bertol.) Kuntze within a humid subtropical mesothermic climate, or Cfb according to the Köppen classification scheme (Reginato et al. 2008). The discovery of these ants underline how little we know about the ant diversity in the Atlantic Forests of Brazil despite their relatively long history of ant collecting, and their proximity to large urban centers such as São Paulo, Rio de Janeiro, and Curitiba. In the case of L. academica, the type series was collected in the landscape immediately surrounding one of the largest entomological collections in the country and home to Brazil’s oldest entomology graduate school. The fact that the specimens representing both species are the product of sampling using pitfall traps proves the usefulness of this technique for collecting these mostly nocturnal predatory ants.	en	López-Muñoz, Román A., Villarreal, Erick, Lattke, John E.

0398BF12FFE9FFAAFF6F84CEFC0B1E15.taxon	etymology	Etymology. The species name is derived from the Brazilian Portuguese noun for a person or thing originally from the state of Rio de Janeiro.	en	López-Muñoz, Román A., Villarreal, Erick, Lattke, John E. (2018): Two new species of Leptogenys from southern Brazil (Hymenoptera: Formicidae). Zootaxa 4410 (3): 559-566, DOI: 10.11646/zootaxa.4410.3.9
0398BF12FFE9FFAAFF6F84CEFC0B1E15.taxon	discussion	Discussion. Workers of L. carioca will key without ambiguity to couplet 30 in Lattke 2011, but then may cause some confusion as the propodeal dorsum does present some degree of punctures and rugulae. Nevertheless there are large areas of smooth and shining cuticle, enough that the irregular sculpturing does not dominate the dorsal propodeal surface, and thus it could be keyed to couplet 34, eventually arriving at couplet 37. A modification of the key in Lattke (2011) is provided below for identifying both L. carioca and L. academica. Besides the characters used in the key for separating these two new species the following morphological differences may also be observed. The pronotal dorsal margin in lateral view is evenly and broadly convex in L. carioca while in L. academica there is a distinct anterior margin separated by a blunt obtuse angle from the mostly horizontal dorsal margin. The metapleuro-propodeal suture in L. carioca is visible as a strip of shallow and short oblique parallel striae but this suture is not discernible in L. academica. Itatiaia National Park protects part of the Itatiaia Plateau in the southern Mantiqueira mountains. The altitudes range from 1000 to 2000 m and most of the forests are classified as either Floresta Ombrófila Densa Alto-montana or Floresta Ombrófila Mista Alto-montana (IBGE, 2012) both with a canopy averaging 20 m high and belonging to an altitudinal subtropical climate (Cwb) in the Koeppen scheme. Temperatures during the year may vary from 3 ° C to 30 ° C, with occasional freezes some eight or so days in a year (Meireles et al. 2014). Known from only two workers, we can only surmise that the species prefers the cooler elevations of the southern Atlantic Forest, ranging close to 2000 meters above sea level. This contrasts with the preference for lowland habitats that is more widespread for the genus (Lattke 2011) and is of interest given the possible negative impact of climate change on mountain inhabiting biota, particularly in the tropics (Lemes et al. 2014).	en	López-Muñoz, Román A., Villarreal, Erick, Lattke, John E.
