“…As noted in the introduction, the tardigrades of Mexico require more extensive taxonomic studies, and currently, only a few faunistic surveys have been published (e.g., [7,[13][14][15][16][17][18][19][20][21][22]). Most of the previous studies have provided an inventory of tardigrade fauna but from non-systematic samplings.…”

The study of tardigrade diversity in Mexico is at early stage of development, to date, 56 extant species have been reported. To identify the tardigrade fauna associated with mosses in the Iztaccíhuatl volcano, we performed a systematic sampling along an altitudinal and multi-habitat gradient. A total of 57 moss samples were collected, 233 adults, 20 exuviae, and 40 free-laid tardigrade eggs were extracted from them. Five species were identified, and three putative species were determined. Diphascon mitrense and Minibiotus sidereus represents new records for Mexico and North America, while Adropion scoticum is a new record for Mexico. Additionally, one new species, Minibiotus citlalium sp. nov. was discovered; it resembles to Min. constellatus, Min. sidereus and Min. pentannulatus by the presence of a similar distribution pattern of star-shaped pores in the dorsal cuticle arranged in 11 transverse rows, which become double in the segments of the legs I–III, and by a very large star-shaped pore (5–6 tips) on each leg of the fourth pair. Minibiotus citlalium sp. nov. differs from other Minibiotus species mainly by macroplacoid length sequence, presence of both small and large star-shaped pores on the external surface on all legs, and by egg processes with inconspicuous ornamentation.

“…87-108). Seven species have been documented in at least two of the five ecoregions [10,[13][14][15][16][17]: 1 in deserts of North America [15,18,19], 9 in great plains [15], 12 in warm-humid forests [10,16,20], 10 in warm-dry forest [10,13,14], and 31 in temperate mountains [14][15][16][17]19,21,22].…”

“…Any tardigrade species thriving in alternative urban habitats but not in natural habitats within a city may have thus gone undetected in previous studies. For example, in the Mexican city of Chetumal some tardigrade species that were not found in moss samples were however present in road sediment, including the recently discovered species Doryphoribius chetumalensis , so far only found in this type of habitat (Pérez‐Pech et al, ; Pérez‐Pech, Anguas‐Escalante, Cutz‐Pool, & Guidetti, ).…”

In different taxonomical groups, the number of species found in urban environments tends to decline compared to adjacent nonurban environments. It is unclear whether tardigrades also conform to this pattern of diversity decline in cities. Tardigrades are microscopic invertebrates which have been understudied, despite the fact that they are cosmopolitan and found in all types of habitats. Due to their capability to withstand extreme conditions, tardigrades should be able to successfully thrive in urban environments. Here, all available information about tardigrade diversity in cities was compiled. It was quantitatively determined that tardigrade diversity declines in urban areas compared to adjacent rural areas. Geographically, closer cities are also likely to harbor a more similar set of tardigrade species. In comparison to other groups like mammals and birds, there are no tardigrade species consistently found in most studied cities. In fact, most urban tardigrades have only been found in one single city. Ultimately, the species of tardigrades found in a given city will normally depend on the set of species already living in the adjacent native environments. One question that deserves further investigation is why only a subset of such native species is able to colonize the new environmental niches available in cities.

Tardigrades, with over 1450 species, are important organisms in ecological understanding and are valuable biological models (e.g., due to their extremotolerant capabilities). While their biodiversity is better known in Europe and North America, Central and South America have only recently started making significant contributions. Through a comprehensive review of scientific literature, biological collections, web portal consultations, and the addition of new records, this study clarifies the current knowledge of tardigrade biodiversity in Colombia. Past research started in the early 20th century, but most data are unreliable due to information gaps and the absence of specimens in biological collections. The last decade has witnessed a resurgence in tardigrade research in Colombia, leading to new species descriptions and a more robust understanding of their biodiversity. Nevertheless, the majority of the territory remains unexplored. A total of 43 known species from our analysis are present in Colombia: 26 records accepted by the literature and 17 questioned in the literature but representing distinct taxa surely present in Colombia. Other species records are considered doubtful. Our study recommends considering mostly scientific records based on verifiable material deposited in scientific collections (highlighting their importance in studying and safeguarding biodiversity) and encourages future researchers to contribute while adhering to legal requirements.
