1. New species of Mayawa Fletcher and description of a related new Australian leafhopper genus (Hemiptera: Cicadellidae: Deltocephalinae: Paralimnini)

   https://doi.org/10.11646/zootaxa.4933.4.8  

   DIETRICH, CHRISTOPHER H. (February 2021, Zootaxa)

   Five new species of the endemic Australian leafhopper genus Mayawa Fletcher, 2000 (M. affinifacialis sp. nov., M. bimaculata sp. nov., M. brevicephala sp. nov., M. kathyae sp. nov. and M. vestigia sp. nov.) are described and illustrated and a revised key to species is provided. One of the new species tested positive for a previously unknown strain of phytoplasma belonging to the 16SrV group. The related paralimnine genus Austroauridius gen. nov. based on A. iwaii sp. nov. from Queensland is also described and illustrated and a key to known genera of Australian Paralimnini is provided.

2. Thirteen new species of Chilecicada Sanborn, 2014 (Hemiptera: Auchenorrhyncha: Cicadidae: Tibicininae) expand the highly endemic cicada fauna of Chile.

   https://doi.org/10.1007/bf00660119  

   Sanborn, Allen F; Cole, Jeffrey A; Stukel, Mark; Lukasik, Piotr; Veloso, Claudio; Gonzalez, Valorie A; Karkar, Jessica B; Simon, Chris (December 2021, Zootaxa)

   The genus Chilecicada Sanborn, 2014 is shown to be a complex of closely related species rather than a monospecific genus. Chilecicada citatatemporaria Sanborn & Cole n. sp., C. culenesensis Sanborn & Cole n. sp., C. curacaviensis Sanborn & Cole n. sp., C. impartemporaria Sanborn & Cole n. sp., C. magna Sanborn & Cole n. sp., C. mapuchensis Sanborn n. sp., C. oraria Sanborn & Cole n. sp., C. parrajaraorum Sanborn n. sp., C. partemporaria Sanborn & Cole n. sp., C. pehuenchesensis Sanborn & Cole n. sp., C. trifascia Sanborn n. sp., C. trifasciunca Sanborn & Cole n. sp., and C. viridicitata Sanborn & Cole n. sp. are described as new. Chilecicada occidentis Walker, 1850 is re-described to facilitate separation of the new species from the only previously known species. Song and cytochrome oxidase I analysis available for most species support the separation of the new taxa from the type species of the genus. Known species distributions and a key to the species of the genus are also provided. The new species increases the known cicada diversity 61.9% to 34 species, 91.2% of which are endemic to Chile.

3. Review of the leafhopper genus Makilingia Baker (Hemiptera: Cicadellidae: Mileewinae)

   https://doi.org/10.11646/zootaxa.4559.3.3  

   DIETRICH, CHRISTOPHER H.; ZAHNISER, JAMES N. (February 2019, Zootaxa)

   The taxonomy of the leafhopper genus Makilingia Baker is reviewed based on comparative morphological study of types and other specimens. Twenty-six species are recognized as valid including ten new species described and illustrated herein: M. davaoensis n. sp. M. lobata n. sp., M. maculamima n. sp., M. nigramima n. sp., M. paranigra n. sp., M. siamensis n. sp., M. tenebrifrons n. sp., M. uncinata n. sp., M. viraktamathi n. sp., and M. xanthopicta n. sp. Makilingia siamensis n. sp. represents the first known occurrence of the genus outside the Philippine Archipelago and the first record for Thailand. Makilingia simillima Baker, n. stat., formerly treated as a variety of M. variabilis Baker, is elevated to full species status based on distinctive differences in the male genitalia. Lectotypes are designated for several species described by Baker. The male genitalia of these species are described and illustrated for the first time and a key to all known species is provided.

4. A Revision of the Peruvian Edrotini (Coleoptera: Tenebrionidae: Pimeliinae)

   https://doi.org/10.3161/00034541ANZ2019.69.1.004  

   Giraldo-Mendoza, Alfredo E.; Flores, Gustavo E. (March 2019, Annales Zoologici)

   The Peruvian genera of Edrotini (Pimeliinae) are revised. A new genus Pachacamacius Flores & Giraldo gen. nov. with two new species, Pachacamacius aguilari Giraldo & Flores sp. nov. (type species) and Pachacamacius koepckeae Flores & Giraldo sp. nov., is described. Two species originally described in the genus ProhylithusKaszab, 1964 are reassigned to two new monotypic genera: Sechuranus Flores and Giraldo gen. nov. (type species Prohylithus barbatusKaszab, 1964) and Koneus Giraldo and Flores, gen. nov. (type species Prohylithus peruanusKaszab, 1981). This article includes diagnoses for five genera and redescriptions or descriptions, distributional data, habitat records and habitus photographs for six species. A dichotomous key for all 11 Peruvian species of Edrotini, drawings of new species' male genitalic features, and distribution maps are also provided. A discussion of the external morphological characters and male genitalia of the new taxa compared to the genera and species previously described and on endemicity and zoogeography of Peruvian Edrotini is presented.

5. Revision of the South American grassland leafhopper genus Cortona Oman (Hemiptera: Cicadellidae: Deltocephalinae: Deltocephalini) with description of four new species from Argentina

   https://doi.org/10.11646/zootaxa.4242.2.8  

   DUAN, YANI; DIETRICH, CHRISTOPHER H.; ZHANG, YALIN (March 2017, Zootaxa)

   The South American leafhopper genus Cortona is moved from Macrostelini to Deltocephalini and is reviewed. Its type species and four new species, C. catanachae sp. n., C. concordica sp. n., C. otamendiensis sp. n., and C. silvai sp. n., are illustrated and described from Argentina. A checklist and a key to species are provided.
