“…Torrenticola rala , described from Mexico and Costa Rica (Cook, 1980), could not be confirmed in the present study, due to uncertainties in the systematic state of the conirostris/rala ‐complex (see respective subsection for discussion). With regard to the complete water mite fauna, Costa Rica has 15% of its species in common with southern Mexico and 5% with Guatemala (Goldschmidt, 2002). These data mainly reflect the very poor knowledge on the water mite fauna of most regions in Central America.…”

In this paper the Latin American species of the water mite genus Torrenticola are presented and discussed comprehensively for the first time. All 21 previously known species from Central and South America are portrayed in detail, descriptions are given for 36 new species from Costa Rica: Torrenticola adunca, T. alargada, T. alexandra, T. alticola, T. altifontana, T. amalgamada, T. ambigua, T. australis, T. baderi, T. chicacoxalis, T. chirripoensis, T. collina, T. conopalpis, T. corta, T. cortobrazo, T. costaricense, T. cumbrensis, T. delgada, T. dispersa, T. elhachensis, T. esferica, T. esquinada, T. fastigata, T. flexirostris, T. fontinale, T. guanacastensis, T. harpagophora, T. levicoxalis, T. menudopalpis, T. monticola, T. pervagata, T. rapidensis, T. ratoncitoi, T. rubella, T. tilaranensis and T. torpebrazo. The Latin American species of Torrenticola are subdivided in a clear, robust system of ten species groups – five of these are regarded as phylogenetic entities, five as rather artificial groups. An identification key to these species groups is given, as well as keys, measurement tables, figures and detailed descriptions of all species within these groups. The males of T. gennada Cook, 1980 and T. keesdavidsi Cramer, 1992, as well as the female of T. amala Cook, 1980 are described for the first time. Descriptions and figures of the genital skeleton of nine formerly described species are given for the first time. All information available on the habitat preferences (habitat type, stream velocity, altitudinal distribution, choriotope types, temperature and conductivity) and the geographical distribution of the species is presented. Zoogeographical characteristics, endemicity and habitat preferences of the 42 species of Torrenticola found in Costa Rica are analysed. The main object of this study is to facilitate further systematic and ecological work on this important genus and to make it accessible for general limnological surveys. © 2007 The Linnean Society of London, Zoological Journal of the Linnean Society, 2007, 150, 443–678.

“…These numbers are certainly not final. An estimated 5,500 may occur in the Neotropics alone, and more than 10,000 species could reasonably be expected to occur in inland waters worldwide (Goldschmidt 2002;Di Sabatino et al 2008).…”

The use of molecular techniques in the taxonomy of water mites (Hydrachnidia, Acari)

et al. 2016

The Hydrachnidia (water mites) are a robust component of aquatic communities in terms of both abundance and species richness. They have colonized all types of freshwater habitats and are highly diversified in both lotic and lentic habitats. Over 6,000 species of Hydrachnidia have been described worldwide, representing eight superfamilies, 57 families, 81 subfamilies and more than 420 genera. Water mite systematics is continually subject to change and various modifications. Performing systematic revisions can lead to numerous misunderstandings and difficulties in comparing research results, as the same species can have different systematic names in different publications. The development of molecular biology techniques has popularized the use of genomic traits in taxonomic identification. Among various markers used to identify species, the most important is the gene encoding cytochrome c oxidase I (COI). Species identification based on this gene is known as 'DNA barcoding'. The use of DNA barcoding was a breakthrough in molecular methods of species identification and has dominated research on invertebrates. It has become possible to identify not only new species, but also species that are difficult to distinguish using traditional methods. Water mites are organisms on which molecular analysis is still rarely performed, as compared to other groups of invertebrates. Fortunately, recent years have seen increasing use of molecular techniques to clarify the intricacies of Hydrachnidia taxonomy. Using DNA markers in the taxonomy of water mites enables definitive resolution of ambiguities in the case of numerous questionable taxa, which is of great importance in all other types of research on these organisms. Wykorzystanie technik molekularnych w taksonomii wodopójek (Hydrachnidia, Acari) Słowa kluczowe analizy molekularne, DNA barcoding, rewizje systematyczne, identyfikacja gatunków Streszczenie Wodopójki (Hydrachnidia) są istotnym komponentem zgrupowań bezkręgowców wodnych zarówno pod względem liczebności, jak i bogactwa gatunkowego. Organizmy te skolonizowały wszelkie rodzaje siedlisk wodnych. Zróżnicowana fauna Hydrachnidia występuje zarówno przełom w molekularnych metodach identyfikacji gatunków i zdominowało badania bezkręgowców. Możliwa stała się nie tylko identyfikacja nowych gatunków, ale także gatunków, które trudno rozróżnić metodami tradycyjnymi. Wodopójki są organizmami, u których wciąż rzadko przeprowadza się analizy molekularne. Jednak w ostatnich latach można zauważyć coraz częstsze zastosowanie tych technik w taksonomii Hydrachnidia. Wykorzystanie markerów DNA w taksonomii wodopójek pozwala na ostateczne wyjaśnienie przynależności taksonomicznej wątpliwych gatunków, co ma ogromne znaczenie we wszelkich badaniach nad tymi organizmami.

“…David Cook (1980) described a further 200 species from Mexico and Guatemala in his seminal work on Central American water mites. Further additions from Mexico by Cramer, Otero-Colina and Galicia (listed by Viets 1987 andCramer 1988), Cramer (1992) and Smith (1991, 1993) significantly increased the species list so that today there are approximately 300 species reported for Central America and Mexico (Goldschmidt 2002).…”
