Abstract. The first checklist of ants of the Mexican state of Tlaxcala, which includes information about 25 species of ants, is given. Twenty two ants species are recorded for the first time for the state of Tlaxcala. Lasius latipes (Walsh, 1863) at the first is reliably indicated for the fauna of Mexico.

Резюме. Составлен список видов муравьев мексиканского штата Тлакскала, включающий 25 видов, 22 из которых приведены для штата впервые. Lasius latipes (Walsh, 1863) впервые достоверно указан для фауны Мексики.

The state of Tlaxcala is one of the smallest of 32 federative entities of Mexico (about 4,061 km2) and is bordered by the states of Hidalgo, Puebla and Estado de México (Fig. 1). It is located in eastern part of Trans- Mexican Volcanic Belt including the northwestern slope of La Malinche volcano (the fifth-highest peak in Mexico, 4461 m a.s.l.).

At the same time, it is one of the most poorly studied states of Mexico myrmecologically. Before our work, only three species of ants from Tlaxcala were known (Liometopum apiculatum Mayr, 1870, Formica retecta Francoeur, 1973 and Pogonomyrmex barbatus (Smith, 1858)) [Vásquez-Bolaños, 2011].

One of purpose of this study was to learn more about altitudinal distribution of ants in Mexico. To study the taxonomic diversity of ants at altitudes above 2600 meters and determine the altitudinal limit of ant distribution, the first author made special investigations in the states of Tlaxcala (La Malinche volcano, in the range of altitudes 2600–3900 m), Estado de México (Nevado de Toluca volcano, 3000–4350 m м) and Tamaulipas (mountains of the Sierra Madre Oriental, municipality of Miquihuana, 2600–3070 m).

We present below the first checklist of ants of the state of Tlaxcala, included 25 species of ants, 22 of them are recorded for the first time for the state. Mention of Lasius latipes (Walsh, 1863) from the state of Tlaxcala is the first record of this species for Mexico based on the specimens.

Material and methods

The material was collected during two short field trips in Tlaxcala in September 2014 and September 2016. Most of the collection was made on the northern slope of the La Malinche volcano (Parque Nacional La Malinche) (Fig. 2b). In 2014, the collections took place in the altitude range from 3000 m a.s.l. to 3800 m a.s.l. along the vertical transect (Fig. 2, localities 6–12) for the purpose to determining the altitudinal limit of the distribution of ants (for more details, see the discussion). In 2016, the collections of ants were taken along a horizontal transect on the same slope of the volcano at altitudes of about 3000 m a.s.l. (Fig. 2, localities 4, 5, 7) and at altitudes of about 2600 m a.s.l. (Fig. 2, localities 2, 3). Also, we studied material from the state of Tlaxcala stored in the National Collection of Insects of the Institute of Biology of National Autonomous University of Mexico (CNIN), which was collected in the western municipality of Nanacamilpa at altitude of 2884 m a.s.l. (Fig. 2a).

Studied specimens of ants are stored in the following museums:

CNIN – Colección Nacional de Insectos, Universidad Nacional Autónoma de México (Mexico City, Federal District, Mexico);

MIFA – Museo de Insectos, Facultad de Agronomía, Universidad Autónoma de Tamaulipas (Ciudad Victoria, Tamaulipas, Mexico);

ZISP – Zoological Institute of the Russian Academy of Science (St. Petersburg, Russia).

To denote various castes of ants, we use the following abbreviations here: w – worker/s, s – soldier/s, q – queen/s, m – male/s.

When quoting labels, the following abbreviations are accepted:

Mpio. – municipality; PN – National park.

Genera and species marked an asterix * in the list below, are recorded for the first time for Tlaxcala. Specific distribution in Mexico is given as in the list of Mexican ant species by Vásquez-Bolaños [2011], new records for other Mexican states, based on our data, are also marked by asterix *.

Synonymic and nomenclature data are given according to “An online catalog of the ants of the world” [Bolton, 2016].

Distribution in Mexico. This species was described from Estado de México and was also known from Puebla [Vásquez-Bolaños, 2011].

Results

Most of the species (23) were collected in the range of altitudes 2600–3055 m a.s.l. Almost all species listed above (excluding Tapinoma cf. litorale Wheeler, 1905) belong to Nearctic faunistic elements.

In La Malinche ants were not found at altitude of over 3255 m, in Nevado de Toluca none above 3152 m, and in Tamaulipas none above 3070 m. In all cases, only 1–2 species of ants were found at these heights. According to the literature data, Formica browni is known at the altitude of 3333 m in Veracruz (Pico Orizaba) [Francoeur, 1973], the same species was found by us with Formica densiventris at the altitude of 3255 m on the La Malinche volcano. Probably, those two species have the highest altitudinal distribution in Mexico. Based on those findings, we state of “altitude boundary” for ants in Mexico at about 3300 m a.s.l. (i.e. Formicidae were not found in localities 9–11 (Fig. 2)).
