Introduction
Termites (Insecta: Blattodea: Isoptera) are eusocial insects whose colonies are composed of reproductives (queens and kings), sterile adults (workers and soldiers), neotenics (future winged adults) and juveniles (nymphs) (Krishna, 1969). The name of this infraorder, coined by French entomologist Gastard Auguste Brullé, comes from the combination of the prefix iso, which means “equal”, and the word pteron, which means “wing”, referencing the subequal size of the anterior and posterior wings of the winged individuals (Krishna et al., 2013a). This infraorder currently comprises a little more than 3100 species grouped in 12 families and 330 genera, including both recent and fossil species (Krishna et al., 2013a).
Termites are distributed in all geographic zones of the world except for the Antarctica (Jones & Eggleton, 2001). The region formed by Canada, continental USA, and Mexico, has a termite fauna comprised of 89 species (including the new records) which are grouped in 26 genera and 4 families. Canada is home to 7 species (2 of them introduced) and one subspecies, these are grouped in 4 genera and 3 families (Evans et al., 2013; Krishna et al., 2013b; c; Snyder, 1949). Of these three countries, Canada is the one that shows the least termite diversity, its native termite fauna being represented entirely by Nearctic species. Continental USA has 47 species (5 of them introduced) and two subspecies, these are grouped in 18 genera and 4 families (Evans et al., 2013; Krishna et al., 2013b-f; Light, 1934b; Snyder, 1949); with a few exceptions found in the southern regions of the country (states of Texas and Florida), most of the native termite fauna of continental USA also correspond to Nearctic species. Mexico has the greatest diversity among these countries with 69 species (2 of them introduced) and a subspecies, which are grouped in 24 genera and 4 families (Evans et al., 2013; Cancello & Myles, 2000; Krishna et al., 2013b-f; Light, 1934c; Méndez-Montiel & Equihua-Martínez, 2001; Scheffrahn, 2016; Snyder, 1949); the termite fauna native to Mexico is a mixture of Nearctic and Neotropical species.
The objective of this article is to provide an illustrated key for the identification of families and genera of termites found in Canada, continental USA, and Mexico, including introduced taxa. Given the key works mainly for the Nearctic region, it pairs well with the key provided by Constantino (2002) for the Neotropics. An updated checklist of the species found in the region is provided, including the geographic distribution to state level in the case of species and subspecies found in Mexico. New state and country records of termites are made for Mexico.
Materials and methods
For the elaboration of the identification key presented in this article, the key from Krishna et al. (2013a) was modified so as to only include the Canadian, American and Mexican genera of the families Archotermopsidae, Kalotermitidae and Rhinotermitidae, discarding the rest; elements of the keys proposed in the works of Constantino (2002b) and Mill (1983) were also included as to add the genera of Termitidae of this region. Original and subsequent descriptions of the genera, as well as identification keys that included them, were also consulted: Banks and Snyder (1920), Bourguignon et al. (2010), Constantino (1994; 2002b), Harris (1960), Krishna (1961; 1962; 1970), Krishna and Emerson (1962), Light (1930a; b; 1932; 1933; 1935; 1937), Lim and Forschler (2012), Maiti (2006), Nickle and Collins (1989; 1990; 1992), Nutting (1990), Scheffrahn (2011; 2016) Scheffrahn and Křeček (2001), Scheffrahn and Su (1994), Scheffrahn et al. (1989; 2000; 2003; 2006; 2015), Snyder (1920; 1922; 1924a-c; 1925a; b; 1926a-c; 1929; 1933; 1952). To illustrate the key, photographs from the official page of the University of Florida Termite Collection (UFTC) https://www.termitediversity.org/ (Scheffrahn, 2020a) were used. The key uses terminology found in Light (1934a), Ricart et al. (2015) and Weesner (1969); an illustration of the termite soldier was redrawn from Light (1934a) for general reference (Fig. 1).
The species checklist is based on the bibliographic revision of the following articles: Araujo (1970; 1977), Banks and Snyder (1920), Cancello and Myles (2000), Capetillo-Concepción et al. (2019), Constantino (1994; 1998; 2002a), Ferraz and Méndez-Montiel (2004), Goellner (1931), Harris (1960), Hernández and Armas (1995), Hernández-Rodríguez et al. (2015), Krishna (1961; 1962), Krishna et al. (2013b-f), Light (1930a; b; 1932; 1933; 1935; 1937), Lim and Forschler (2012), Méndez-Montiel and Equihua-Martínez (2001), Myles (1995; 1997), Myles and Méndez-Montiel (2017a-d), Nalepa (1998), Nutting (1969; 1970), Scheffrahn (2011; 2016; 2020b; c), Scheffrahn and Křeček (2001), Scheffrahn and Rust (1983), Scheffrahn and Su (1987; 1995; 2005), Scheffrahn et al. (1988; 1989; 1998; 2000; 2001; 2002; 2005; 2006; 2015), Snyder (1920; 1922; 1924a-c; 1925a; b; 1926a-c; 1929; 1933; 1952), Su et al. (1997) and Weesner (1970). The database containing the records of the UFTC (Scheffrahn, 2020a), updated the 31st of July 2020 at the time of writing, was also used.

The termite fauna found in Continental North America is represented by four of the twelve extant families of termites; except for the introduced taxa, the species are akin to either the Neotropical realm, the Nearctic realm, or both (Araujo, 1970; Weesner, 1970). The family Archotermopsidae (dampwood termites) is represented by a single genus (Zootermopsis) of wood-dwelling termites which is found exclusively in the Nearctic realm, the other two genera of this family are found in the Oriental and Palearctic regions; meanwhile, the remaining families (Kalotermitidae, Rhinotermitidae, and Termitidae) have a worldwide distribution. The family Kalotermitidae (drywood termites) is represented by eleven genera of wood-dwelling termites, some are akin to the Nearctic realm (Kalotermes, Marginitermes, Paraneotermes and Pterotermes), some to the Neotropical realm (Glyptotermes, Rugitermes and Procryptotermes), while some are found in both (Calcaritermes, Cryptotermes, Incisitermes and Neotermes). The family Rhinotermitidae (subterranean termites) is represented by four genera, three of which (Coptotermes, Heterotermes, and Reticulitermes) are subterranean termites which can be found in both the Nearctic and the Neotropical realms; the other genus (Prorhinotermes) has a wood-dwelling species associated with coasts and akin to the Neotropical realm. Finally, the family Termitidae (higher termites) is represented by ten genera of mostly subterranean termites, but some can build nests high up in the trees; in the region, all species are akin to the Neotropical realm and can be found in Mexico (Amitermes, Anoplotermes, Cahuallitermes, Gnathamitermes, Hoplotermes, Microcerotermes, Nasutitermes, Parvitermes, Tenuirostritermes, and Termes), but a few species can be found in southernmost USA.
In the works of Cancello and Myles (2000) and Méndez-Montiel and Equihua-Martínez (2001), records of several species for Mexico are questioned, nevertheless, evidence exists to confirm their presence. Neotermes jouteli (Nickle & Collins, 1990; Scheffrahn et al., 2000), Neotermes larseni (Nutting, 1970), Heterotermes convexinotatus (Light, 1934c; 1935 - identified as Heterotermes orthognathus; Nickle & Collins, 1990), Reticulitermes flavipes (Banks & Snyder, 1920; Light, 1934b; Snyder, 1926a), Termes hispaniolae (Light, 1933; 1934c - identified as the next species) and Termes panamaensis (Nickle & Collins, 1990) are part of the Mexican termite fauna, since, besides being mentioned for Mexico in at least one article (without including catalogues), they are distributed naturally in nearby regions, which makes their distribution in Mexico plausible. Coupled with this, Mexican specimens of Heterotermes convexinotatus, Neotermes jouteli, and Termes hispaniolae are represented in the UFTC (Scheffrahn, 2020a).
On the other hand, Microcerotermes strunckii (Sörense, 1884) is eliminated from the listing of Mexican species, due to its only mention for Mexico being from a catalogue (Constantino, 1998). The species Coptotermes crassusSnyder, 1922, Coptotermes havilandi Holmgren, 1911, Incisitermes perparvusLight, 1933, Nasutitermes costalis (Holmgren, 1910), Incisitermes nigritus (Snyder, 1946) and Termes melindaeHarris, 1960, also mentioned as part of the Mexican termite fauna (Cancello & Myles, 2000; Ferraz & Méndez-Montiel, 2004; Méndez-Montiel & Equihua-Martínez, 2001), are eliminated, because at present they are considered synonyms of Coptotermes testaceus (Scheffrahn et al., 2015), Coptotermes gestroi (Maiti, 2006), Incisitermes seeversi (Krishna et al., 2013b), Nasutitermes corniger (Scheffrahn et al., 2005), Incisitermes platycephalus (Scheffrahn, 2020c), and Termes hispaniolae (Scheffrahn, 2020b), respectively. Although Cryptotermes domesticus (Haviland, 1898) and Cryptotermes dudleyi, 1918 Banks have been intercepted in Canada (Myles, 1995), there have not been records of the establishment of colonies of said species in that country, and for that reason they have not been included in the checklist; similar is the case of Incisitermes platycephalus which has been intercepted in the USA (Gay, 1967; 1969 - identified as Incisitermes nigritus). Finally, neither Reticulitermes okanaganensis Szalanski, Austin, Mckern & Matthew, 2006, recorded for Canada and the USA, nor Tenuirostritermes seeversi Mathur & Thapa, 1962, recorded for Mexico, are included in the checklist, this is due to them being considered nomina nuda (Krishna et al., 2013c; e).
The three Mexican states with the highest diversity of termites are Jalisco with 29 species, Colima with 25 species and Quintana Roo with 21 species. In contrast, the states of Durango, Hidalgo, Morelos, Queretaro, and Zacatecas do not have formal records of any species of termite. Setter and Myles (2005) mention the presence of an undescribed species of Microcerotermes Silvestri, 1901 for the state of California, USA, as well as several undescribed species for some Mexican states. Similarly, Méndez-Montiel and Equihua-Martínez (2001), as well as Myles and Méndez-Montiel (2017a-d) mention the presence of several undescribed species of termites for Mexico, therefore, the number of species of termites of this region is expected to increase in the following years.
