... Our finding that individual workers had significantly less pyrazine content than individual male and female alates is consistent with the findings of prior research on S. invicta (Vander Meer et al., 2010). Worker and alate castes were also found to differ in the concentration of alarm pheromones in Camponotus abdominalis (Blum et al., 1988) and some other ant species (Brand et al., 1973;Lloyd et al., 1975;Do Nascimento et al., 1993;Hernández et al., 1999). This leads to the question: If an alarm pheromone is predominantly used to recruit workers to defend a nest or resources, why do alate castes produce more alarm pheromone? ...

... In the Neotropical region, Emery (1925), reviewed the subfamily Formicinae, made the first key for identifying the subgenera, and created species groups based on major and minor worker morphology. Since then, the only identification keys produced for Neotropical Camponotus are for Argentina (Kusnezov 1952), Cuba (Alayo 1974), Chile (Snelling and Hunt 1975), Puerto Rico and the Virgin Islands (Snelling 1998) and Colombia (Mackay and Mackay 2019). In addition to high species richness, Camponotus workers are usually dimorphic, with minor and major worker subcastes (Emery 1925) exhibiting a wide allometric range. ...

... The genus Brachyponera Emery, 1900, was initially established as a subgenus of Euponera Forel, 1891 with the type species E. (B.) croceicornis (Emery, 1900), and later elevated to the genus level (Bingham 1903). Subsequently, it was synonymized with the genus Pachycondyla F. Smith, 1858 (Snelling 1981) and placed within the tribe Ponerini (Bolton 2003). Since the 21 st century, with the widespread application of molecular phylogenetic analysis, the subgenus Brachyponera has been reinstated as an independent genus and placed under the Odontomachus genus group of the tribe Ponerini (Schmidt 2013;Schmidt and Shattuck 2014). ...

... Some of the earliest research on mangrove ants looked at the fauna of the Everglades in southern Florida (Simberloff and Wilson, 1969). Afterwards the mangrove ants have been study along the Caribbean and Florida Keys archipelago (Cole, 1983;Wetterer and O'Hara, 2002), Mexico (Dejean et al., 2003;Reynoso-Campos et al., 2015) and Colombia (Gómez-Cifuentes, 2011;Pinto-Méndez et al., 2011), all in the Atlantic coasts. In addition, researchers have looked into the relationship between ants and the nectaries of Hibiscus pernambucensis, a shrub species commonly found within the mangrove on the Atlantic Brazilian coast (Cogni and Freitas, 2002;Cogni et al., 2003). ...

... Its phylogeny is well understood, reflecting its coevolution over 50 million years with nitrogen-recycling bacteria, originating in the South American Cerrado region (Russell et al. 2009;Sanders et al. 2014;Graber et al. 2023). Its microbiome allows it to consume nitrogen sources and carbohydrates, such as pollen, lichens, nectar, homopteran secretions, and bird and lizard droppings (Baroni Urbani and De Andrade 1997; Davidson et al. 2004;Byk and Del-Claro 2010;Ramalho and Moreau 2023) without the need to consume protein directly. Colonies of many Cephalotes species tend to be founded by a single queen (De Andrade and Urbani 1999), though C. atratus is facultatively polygynous (Price 2011), as may be other species in the genus. ...

... Although typically found in seasonally flooded or pre-montane forests [58], these species exhibit ecological plasticity that enables them to serve as phorophytes in areas with greater solar exposure. This facilitates ant and epiphyte interactions in more open environments (T1) [59], promoting ant proliferation that benefits both phorophyte and epiphyte protection [60]. ...

... Their colony size is usually less than 100 individuals (Brown, W. L., 1978). To my knowledge, 25 out of 115 Anochetus species are known to possess an alate/ dealate queen that independently founds a new colony (Brown, W. L., 1978;Villet et al., 1991;Ito & Ohkawara, 1994;Torres et al., 2000;Gobin et al., 2006;Kugler & Ionescu, 2007;Fisher & Smith, 2008;González-Campero & Elizalde, 2008;Tinaut et al., 2011;Shattuck & Slipinska, 2012;Satria et al., 2017;Leong et al., 2018;Chen et al., 2019), whereas nine species are known to possess an ergatoid (wingless) queen that performs dependent colony foundation (Brown, W. L., 1978;Lattke, 1986;Villet et al., 1991;Torres et al., 2000;Gobin et al., 2006;Fisher & Smith, 2008;Satria et al., 2017), and both alate and ergatoid queens have been reported in three other species (Brown, W. L., 1978;Tinaut et al., 2011). Further studies are required to understand how the reproductive strategies of these species have evolved divergently. ...
