Seven new euptychiine (Lepidoptera: Nymphalidae: Satyrinae) taxa are described and named herein, namely Harjesia argentata Nakahara, Zacca and Lamas, n. sp., Orotaygetis Nakahara and Zacca, n. gen., O. surui Nakahara, Zacca and Lamas, n. sp., Euptychoides sanmarcos Nakahara and Lamas, n. sp., Pseudeuptychia cuzquenya Nakahara and Lamas, n. sp., P. languida austrina Nakahara and Lamas, n. ssp., and Godartiana astronesthes Lamas and Nakahara, n. sp. A revisional note is provided for Harjesia Forster, 1964 and Pseudeuptychia Forster, 1964, and as a result, Taygetis vrazi Kheil, 1896 is removed from Harjesia and a new taxonomic arrangement, Pseudodebis vrazi n. comb., is proposed based on both morphology and molecular data.
Umbyquyra gen. nov., a new Theraphosinae genus with stridulatory bristles on the palpal trocanther of pedipalp trochanter and first leg, is proposed. The genus differs from the other genera with stridulatory bristles on the same segments, Acanthoscurria Ausserer, 1871, Cyrtopholis Simon, 1892, Longilyra Gabriel, 2014 and Nesipelma Schmidt & Kovarik, 1996, by having a palpal bulb with a very short and acuminate embolus and four short keels; separated tibial apophysis; and female spermathecae resembling those of Cyrtopholis, with two seminal receptacles with elongated ducts emerging from a common area. Cyrtopholis palmarum Schiapelli & Gerschman, 1945 and C. schmidti Rudloff, 1996 from Brazil and Acanthoscurria acuminata Schmidt & Tesmoingt in Schmidt, 2005 from Bolivia are transferred to the new genus. The female of Umbyquyra palmarum (Schiapelli & Gerschman, 1945) gen. et comb. nov. and the male of U. schmidti (Rudloff, 1996) gen. et comb. nov. are described for the first time. Cyrtopholis zorodes Mello-Leitão, 1923 is considered a junior synonym of Acanthoscurria gomesiana Mello-Leitão, 1923 and Cyrtopholis meridionalis (Keyserling, 1891) is considered a nomen dubium. Eight new species from Brazil are described: Umbyquyra paranaiba gen. et sp. nov., U. cuiaba gen. et sp. nov., U. araguaia gen. et sp. nov., U. sapezal gen. et sp. nov., U. belterra gen. et sp. nov., U. caxiuana gen. et sp. nov., U. tucurui gen. et sp. nov. and U. tapajos gen. et sp. nov. Data and maps on the geographic distribution are provided.
Afrocampe gen. nov. is described for its only species, A. prinslooi gen. et sp. nov., from Eastern and Western Cape, South Africa. This new genus is recognized as a member of the subfamily Tetracampinae Förster, 1856 of Tetracampidae Förster, 1856 based on the possession of 5-segmented tarsi in females and 4-segmented tarsi in males, the short straight calcar, the mesoscutum with distinct notauli, the mesoscutellum with two pairs of setae, the reduced mesopleural suture and the short stigmal and long postmarginal veins of the fore wing. Afrocampe gen. nov. is characterized by a large mesosoma, a non-convex first gastral tergite, an evenly acute calcar, a 5-segmented antennal funicle, a head lacking occipital carina and facial grooves and a long fore wing with distinctly delimited speculum, a bare admarginal area with a distinct admarginal row of setae on the underside and with 3 setal tracks (hair rows) radiating from the apex of the stigmal vein. The combination of these characters suggests a special status of the new genus within the subfamily Tetracampinae. Moreover, Afrocampe gen. nov. bears some resemblance to the Australian tetracampine genus Niticampe Bouček, 1988. The position of the latter in Tetracampinae, as well as habitus features of the former, are discussed.
Synchroidae Lacordaire, 1859 is a taxonomically and biologically poorly known group. In the present paper, diagnostic characters used to separate genera are analysed and the phylogenetic relationships within this family are preliminarily investigated. Results suggest that the characteristic Synchroa pangu Hsiao, Li, Liu & Pang, 2016 can be removed to establish a new genus, Thescelosynchroa gen. nov. The new combination, T. pangu (Hsiao, Li, Liu & Pang) gen. et comb. nov., is proposed. The definitions of Synchroa Newman, 1838 and Synchroina Fairmaire, 1898 are revised. Moreover, morphological analysis and character comparison also suggest that the familial placement of Mallodrya subaenea Horn, 1888 is questionable. Six species are re-examined and rediagnosed: Synchroa chinensis Nikitsky, 1999, S. elongatula Nikitsky, 1999, S. formosana Hsiao, 2015, S. melanotoides Lewis, 1895, S. punctata Newman, 1838 and Synchroina tenuipennis Fairmaire, 1898. The male of S. chinensis and the female of S. formosana are described for the first time. Synchroa elongatula and Synchroina tenuipennis are newly recorded from Laos and Indonesia, respectively. We also hypothesize that the Eastern Asian-North American disjunction of Synchroa could be connected to a Mid-Late Tertiary migration of plants via the Bering Land Bridge.
