The water mite Hydrachna guanajuatensis Cook, 1980 is recorded as an ectoparasite of Ranatra sp. (Nepidae), Notonecta sp., Buenoa sp. (Notonectidae), Krizousacorixa femorata (Guerin, 1857), Trichocorixella mexicana (Hungerford, 1927), and Hesperocorixa laevigata (Uhler, 1893) (Corixidae). The host body region, where the larvae and protonymph attach, depends significantly on the heteropteran species: chi(2) = 3969.43, p < 0.05 and chi(2) = 1893.6, p < 0.05, respectively. We performed a cross tabulation with a correspondence analysis and found three associations for the larvae: 1) dorsal side of abdomen underneath the wings of the two species of Notonectidae, 2) head, wings, and hind legs of two of the species of Corixidae (T. mexicana and K. femorata), and 3) thorax and fore and middle legs of the single species of Nepidae. These different patterns are discussed according to morphological and ecological characteristics of the hosts. This is the first study that deals with the spatial distribution patterns within the same species of ectoparasite.
