Two new genera and seven new species, collected in the state of Oaxaca in Mexico, are described. The genera Reyesacris (R. amedegnatoae) and Oaxaca (O. colorata and O. carinata) are new to science. Melanoplus mixes, M. oaxacae and M. ludivinae are new species for the genus Melanoplus Stål, 1873 and Cephalotettix chinantecus is new species for the genus Cephalotettix Scudder, 1897.

Two new species of Pyrgomorphidae of the Mexican endemic genus Ichthyotettix Rehn, 1901, are described: Ichthyotettix stricticaudatus n. sp. (from Oaxaca) and Ichthyotettix inexpectatus n. sp. (from Morelos and Michoacan). The identity of the genus Ichthyotettix, to date considered monotypic, within the tribe Ichthyotettigini is discussed and the type locality of Ichthyotettix mexicanus (Saussure, 1859) is examined and restricted to Veracruz state. The two new species are well characterised both for their morphological external characters as well for male genitalia. © 2011 · Magnolia Press. Source

Three new species of Katydids from Mexico are described in Insara Walker, 1869: I. oaxacae and I. acutitegmina, respectively, collected in Oaxaca and Chiapas states and Arachnitus apterus n. sp. of Arachnitus Hebard, 1932 from Puebla and Oaxaca states. Copyright © 2011 Magnolia Press. Source

The water mite Hydrachna guanajuatensis Cook, 1980 is recorded as an ectoparasite of Ranatra sp. (Nepidae), Notonecta sp., Buenoa sp. (Notonectidae), Krizousacorixa femorata (Guérin, 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: χ2 = 3969.43, p < 0.05 and χ2 = 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. ©2015, Taylor & Francis. Source

Here, we provide new records of suctorians (Ciliophora: Suctoria), epibionts of aquatic true bugs (Hemiptera: Prosorrhyncha: Nepomorpha) collected in Ukraine, Belarus and Mexico. The worldwide distribution of the 16 species we found is updated, from which, 15 species are new records as epibionts of 15 species of aquatic true bugs. Only for the suctorian Discophrya gessneri Matthes, we confirm the previous record (epibiont of Aphelocheirus aestivalis Fabricius). We conclude that the relationship between the suctorians and aquatic true bugs is poorly studied and some suctorian genera (Discophrya Lachmann and Periacineta Collin) inhabit as nepomorphans as other aquatic insects (Coleoptera). However the high degree of specificity at the species level of these genera is evident, for which we provide some possible explanations according to the group of basibiont.
