“…They can be parasitized mostly as imagos following the hatch, to which water lice larvae are attached following parasitism during the pupal stage of the black fly [ 19 ]. Therefore, in this study we provide information on the prevalence and intensity of water mite parasitism on black fly pupae in the field for a broad span of territory in eastern Spain where the abundance of black fly species is already beginning to be treated as a public health issue [ 33 , 55 – 58 ].…”

Background Documentation on water mites in Spain is scarce, as is information on the parasite-host relationship between certain water mite species and representatives of the dipteran family Simuliidae. The discomfort caused to humans and animals by black flies seems to be increasing in recent years. In this context, an investigation of parasitic water mites is of great importance, not only from the point of view of biodiversity, but also in terms of their potential to control black fly populations. Methods Rivers across a wide region of eastern Spain were sampled to determine the specific richness of simuliid dipterans and to investigate their possible parasites, such as water mites, mermithid nematodes and microsporidia (fungal microbes). Data on environmental variables, abundance, prevalence and intensity of parasitism on the collected specimens were analyzed. Results In 10 streams, 15,396 simuliid pupae were collected and checked for the presence of water mite larvae; 426 pupae in seven streams were found to be associated with water mite larvae. Of the 21 simuliid species identified based on morphological characters, eight were found to be associated with water mite larvae. Water mite infection was not equally distributed among black fly species. Also, the prevalence of parasitism was low and differed among simuliid species, ranging from one to 13 water mites per black fly pupa. Variation at the intra- and interspecific levels was detected in terms of the number of water mites inside the black fly cocoons. Free-living deutonymphal and adult water mites representing 15 different species of six genera and five families were morphologically identified. The taxonomic identity of the parasitic mite larvae is unclear at present. Morphologically, they fit descriptions of larval Sperchon (Hispidosperchon) algeriensis Lundblad, 1942, but the possibility cannot be excluded that they represent Sperchon algeriensis, the most abundant species at the adult stage in this study and unknown at the larval stage, or even another species of the genus. A molecular analysis produced for the first time cytochrome oxidase I gene sequences for S. algeriensis. Conclusions Our results contribute to current knowledge on Spanish Hydrachnidia and their relationships with simuliids as hosts. However, further research is needed to evaluate the diversity, distribution, bioecology and prevalence of this parasitism. Graphical Abstract

The objectives of this study were to analyse the diversity and geographical distribution of the blackfly species from the Huebra River basin located in Salamanca province, Western Spain. This research significantly contributes to expanding our knowledge of the Simuliidae family. The study not only increases and ameliorates faunal and bioecological data, but also enhances the understanding of blackfly species across the Spanish national territory. The identification of 23 species has led to the addition of six new records to the simuliid fauna of the region: Simulium (Nevermannia) armoricanum Doby & David, 1961; Simulium (Nevermannia) carthusiense Grenier & Dorier, 1959; Simulium (Nevermannia) naturale Davies, 1966; Simulium (Nevermannia) vernum Macquart, 1826; Simulium (Simulium) bezzii (Corti, 1914) and Urosimulium faurei (Bernard, Grenier & Bailly-Choumara, 1972), expanding the previously recorded 19 species to 25. This study also provides valuable insights into the biology and geographical distribution of these species. It sheds light on the ranges of altitude, water velocity, temperature and the depth of watercourses conducive to preimaginal development. Additionally, it offers new information on the abundance of larvae and pupae, revealing the diverse ecological gradients that influence their occurrence and distribution patterns. The results indicate that the diversity of blackfly species varies according to factors such as altitude, water velocity, turbidity, and water temperature.
