Over 700 moss, lichen and hepatic samples were collected from territory of Costa Rica. Tardigrades were present in nearly half of the samples. Overall, more than 7000 tardigrades were found. All specimens were identified as 64 species belonging to 18 genera. The number of species per positive sample varied between 1 and 10, but on average it did not exceed three. The most important factor influencing distribution of Tardigrada in Costa Rica was altitude. Tardigrades most often inhabited mosses, lichens and hepatics collected from 2000 to 2400 m asl and above 3200 m asl (more than 70% positive samples). The highest Tardigrada species diversity was found between 1400 and 2000 m asl (35 species, 55%), and the lowest between 2400 and 2800 m asl (18 species, 28%). The second strongest factor that influenced tardigrade distribution was the type of environment. A significantly higher proportion of positive samples were found in urban and agricultural areas (about 60%) than in natural habitats (only about 30%). The highest frequency of positive samples was found in humid habitats. Surprisingly, among all analysed factors, the substrate and plant type had the weakest influence on tardigrade distribution.

In a moss sample collected in Ribeiro Frio, Madeira, Paramacrobiotus gadabouti sp. nov. was found and described using the integrative taxonomy approach. The new species is described based on morphological and morphometric data from both phase-contrast light microscopy (PCM), as well as scanning electron microscopy (SEM). Moreover, four DNA markers, three nuclear (18S rRNA, 28S rRNA, ITS-2) and one mitochondrial (COI) markers, were used to elucidate the phylogenetic position of the new species within the family Macrobiotidae. The new species has a microplacoid that placed it within Parmacrobiotus richtersi group and exhibit richtersi-type eggs having processes terminated with cap-like structures. Paramacrobiotus gadabouti sp. nov. is most similar to Pam. alekseevi, Pam. filipi and Pam. garynahi, but differs from them mainly in details of egg morphology and morphometrics. Unlike other species from this group, which were confirmed as bisexual and showed limited distribution, Paramacrobiotus gadabouti sp. nov. is yet another parthenogenetic species with a wide distribution, demonstrating that at least some tardigrades confirm to the hypothesis of 'everything is everywhere'.

In sixteen moss, lichen and mixed (moss/lichen) samples, collected from Estonia, Latvia and Lithuania, 291 specimens, 48 simplexes, including one exuvium with 6 eggs, and 8 free-laid eggs of eutardigrades were found. In total, 17 species, together with one new to science, were identified (all are new records for the Baltic states): Astatumen bartosi, Diphascon (Adropion) prorsirostre, D. (Diphascon) bullatum, D. (D.) pingue pingue, D. (D.) recamieri, D. (D.) rugosum, Hypsibius convergens, H. dujardini, H. cf. scabropygus, Isohypsibius ronsisvallei, I. sattleri, Macrobiotus harmsworthi harmsworthi, M. hufelandi hufelandi, Milnesium asiaticum, Milnesium tardigradum tardigradum, Minibiotus formosus sp. n. and Paramacrobiotus richtersi. The new species is most similar to Minibiotus gumersindoi, but differs from it mainly by the presence of two types of cuticular pores, the absence of a triangular or pentagonal arrangement of pores above a single large pore on legs, the presence of granulation on all legs and a different macroplacoid length sequence. In this paper we also provide photographs and morphometrics of H. cf. scabropygus.

A new speciesMacrobiotus magdalenae(Tardigrada: Eutardigrada: Macrobiotidae,richtersigroup) from Costa Rican rain forest (Central America)

Abstract: A new species Macrobiotus magdalenae sp. nov. is described from a liverwort sample collected in Costa Rica (Central America). The new species is most similar to Macrobiotus corgatensis Pilato et al., 2002 but differs from it mainly by the lack of fine granulation on the cuticle.
