Supplementary descriptions are provided for six poorly known species of Caligus, based on a study of type and other material carried out by the late Roger F. Cressey but never published. As part of that study new illustrations were produced by Hillary Boyle Cressey who has kindly made these previously unpublished drawings available to this paper. The present account also contains critical re-assessments of the validity of several other species of Caligus Müller, 1785. It is proposed to recognise that: C. glacialis Gadd, 1910 and C. raniceps Heegaard, 1943 are junior subjective synonyms of the type species C. curtus Müller, 1785 and we consider the published geographical locality given for C. raniceps by Heegaard (1943) to be erroneous; C. guerini Guiart, 1913 is a junior subjective synonym of C. elongatus von Nordmann, 1832; C. mordax Leigh-Sharpe, 1934 is a junior subjective synonym of C. coryphaenae Steenstrup & Lütken, 1861; C. lessonius Risso, 1826 is not a caligid and is probably a junior synonym of the pandarid Demoleus heptapus (Otto, 1821); C. clavatus Kirtisinghe, 1964 is a junior subjective synonym of C. sphyraeni Pillai, 1963; C. rotundigenitalis Yü, 1933 is a junior subjective synonym of C. torpedinis Heller, 1865; C. hyalinae Heegaard, 1966 is a junior subjective synonym of C. chelifer Wilson, 1905; C. biseriodentatus, Shen, 1957 is a junior subjective synonym of C. pauliani Nuñes-Ruivo & Fourmanoir, 1956; and C. cornutus Heegaard, 1962 can be formally treated as a junior subjective synonym of C. lobodes (Wilson, 1911) because the name C. cornutus belongs with the male holotype; the female allotype collected by Heegaard (1962) remains unidentified. We also conclude that C. mebachii Marukawa, 1927 was based on a young male of Euryphorus brachypterus (Gerstaecker, 1853) and a male of Caligus coryphaenae Steenstrup & Lütken, 1861 which was mistakenly identified as the female. A lectotype is designated for C. mebachii and this species is treated as a synonym of Euryphorus brachypterus. It is noted that C. hamatus Heegaard, 1955 is conspecific with, and has priority over, C. undulatus Shen & Li, 1959. However, given that C. undulatus is a high profile and well known species, frequently recorded from across the Pacific, Indian and Atlantic oceans, a case has been submitted to the ICZN to grant precedence of C. undulatus over C. hamatus. We reject the transfer of Chalimus tenuis Leidy, 1889 to Caligus by Fowler (1912) on the basis of lack of evidence supporting the transfer, and return it to Chalimus, where it can be treated as a species inquirendum within a genus that is no longer considered as valid. We consider that C. alalongae Krøyer, 1863 and C. gracilis Dana, 1852 are species inquirenda. Caligus truttae is a nomen nudum because Giard (1890) provided no morphological information or illustration associated with the new name.

Taxonomic clarification of two Nearctic Strumigenys (Hymenoptera: Formicidae)
In 1901, Forel described an ant species from a relatively poorly known genus of ants from North America, naming it Strumigenys pilinasis. In 1931 M. R. Smith obtained the holotype and redescribed it, and he included a first illustration. The description was incomplete and the illustration resembled Strumigenys brevisetosa Smith, 1935, more than it resembled S. pilinasis, which led subsequent taxonomists to make consistent misidentifications and to consider S. brevisetosa to be a synonym of S. pilinasis. Here I redescribe both S. pilinasis and S. brevisetosa (revived status). Strumigenys manni Wesson & Wesson, 1939, and S. ohioensis Kennedy & Schramm, 1933, are new junior synonyms of S. pilinasis, and S medialis Kennedy & Schramm, 1933, is a new junior synonym of S. brevisetosa.

The Austrothaumalea fauna of South America is revised and includes five species: A. apicalis Edwards, A. chilensis Edwards, A. fredericki Pivar sp. nov., A. setipennis Edwards stat. rev. and A. spatulata Schmid. The genus Oterere McLellan syn. nov. is considered a new junior synonym of Austrothaumalea Tonnoir on the basis of several shared apomorphic characters. All previously described South American species are redescribed, including females where possible. Illustrations and micrographs of all species are provided, as well as distribution maps, keys to genera and species, and discussions regarding phylogenetic affinities.more » « less

null (Ed.)The Mexican leafhopper genus and species Devolana hemicycla DeLong, 1967 syn. nov., is recognized as a junior synonym of Usanus stonei DeLong, 1947. Three previously described species, U. tuxcacuensis (Pinedo-Escatel & Aguilar-Pérez, 2019) comb. nov., U. youajla (Pinedo-Escatel, 2019) comb. nov., and U. xajxayakamej (Pinedo-Escatel, 2019) comb. nov. are transferred to Usanus. Two new species, U. xochipalensis sp. nov. and U. igualaensis sp. nov. from Guerrero, are described and illustrated. An updated key to all known species of Usanus is provided.more » « less

null (Ed.)A recent paper by Ruschel & Campos (2019) on “leaf-winged” cicadas proposed a significant reorganization of the cicada tribe Hemidictyini Distant, 1905g, including synonymization of the monogeneric tribe Lacetasini Moulds & Marshall, 2018 following the results of a cladistic parsimony analysis of morphological characters. In this study, we reconsider and revise the morphological analysis of Ruschel & Campos and obtain new genetic data for Hemidictya. We find that their study suffers from a limited taxon sample, inappropriate outgroup selection, and misinterpretation of genitalic characters (uncus vs. claspers). We show that Hemidictyini sensu Ruschel & Campos includes members of multiple tribes and subfamilies, and we conclude that some of the taxonomic transfers by Ruschel & Campos are not supported. The two most similar and leaf-like cicadas, Hemidictya Burmeister, 1835 (South America) and Hovana Distant, 1905g (Madagascar), are probably not closely related but rather an excellent example of convergent evolution. Lacetasini is not a junior synonym of the Hemidictyini but a distinct part of the Tettigomyiinae Distant, 1905g as originally classified. We return or transfer the genera Lacetas Karsch, 1890, Iruana Distant, 1905g, Bafutalna Boulard, 1993, and Murphyalna Boulard, 2012 to the Lacetasini. With the transfer of all genera of Iruanina Boulard, 1993 and Bafutalnina Boulard, 1993 to Lacetasini and with Lacetas transferred to the Iruanina, Lacetasini n. syn. becomes a subjective junior synonym of Iruanini rev. stat. in the Tettigomyiinae. We assign Hovana to Hovanini n. tribe in the Tettigomyiinae and Sapantanga Distant, 1905g to Sapantangini n. tribe in the Tibicininae Distant, 1905b. We propose that Hemidictyini sensu novo contains only the genus Hemidictya and we assign the tribe to Tibicininae with a revised diagnosis.more » « less

null (Ed.)Three new Neotropical athysanine (Deltocephalinae) leafhopper genera, Spaltumtettix Pinedo-Escatel & Dietrich gen. nov., Pseudonapo Pinedo-Escatel & Dietrich gen. nov., and Goiattus Pinedo-Escatel gen. nov., and 4 new species, S. coloradus Pinedo-Escatel & Dietrich sp. nov. (Peru), P. waorani Pinedo-Escatel & Dietrich sp. nov. (Ecuador), P. huanucensis Pinedo-Escatel & Dietrich sp. nov. (Peru), and G. reyesi Pinedo-Escatel sp. nov. (Brazil), are described and illustrated. In addition, the genera Zabrosa Oman, Napo Linnavuori & DeLong, Pseudalaca Linnavuori and Brazosa Oman are revised and redescribed. Six new species are described in Brazosa: B. campinacu Pinedo-Escatel & Dietrich sp. nov. (Brazil), B. espatula Pinedo-Escatel & Dietrich sp. nov. (Brazil), B. encrustada Pinedo-Escatel & Dietrich sp. nov. (Brazil), B. mildredireanae Pinedo-Escatel sp. nov. (Peru), B. negra Pinedo-Escatel & Dietrich sp. nov. (Peru and Bolivia) and B. beni Pinedo-Escatel & Dietrich sp. nov. (Bolivia). Brazosa caesarea Linnavuori & Heller comb. nov. is transferred to Spaltumtettix. The South American species Z. aquareza Linnavuori & DeLong syn. nov. is proposed as junior synonym of Z. unicampi Menezes. Keys to species of each genus are provided. Unusual aspects of the morphology of these genera are discussed and a comparative table is provided.more » « less
