The genus Oplognathus MacLeay, 1819 is revised based on type material of two of the three described species and scattered additional material from several collections around the world. The diagnostic characters of the genus are confirmed, distinguishing it from other Brazilian Areodina mainly by: quadrangular clypeus with trilobate apex in males, rounded in females, extending beyond labrum in both sexes; mandibles with three distinct teeth; maxillae with six teeth; antenna with 10 antennomeres; 10 elytral striae; mesoventral process present; and asymmetrical parameres. The genus and all three species are redescribed, and the female of Oplognathus bahianus Ohaus, 1912 is described for the first time. We consider Oplognathus helmenreichi var. maculicollis Ohaus, 1914 an unavailable infrasubspecific taxon that is conspecific with Oplognathus helmenreichi Ohaus, 1905; its distribution is updated, and the different spelling of the specific epithet is discussed. A neotype is designated for Oplognathus kirbii MacLeay, 1819 since the holotype is currently considered lost. Additionally, an identification key and a distribution map are included.

A new species of water scavenger beetle, Laccobius (Glyptolaccobius) yinziweii sp. nov. is described from Yunnan, China. Diagnostic characters are illustrated. Laccobius (Cyclolaccobius) nitidus Gentili, 1984 is reported from Guizhou, Laccobius (Microlaccobius) hammondi Gentili, 1984 from Hubei, and Laccobius (s. str.) inopinus Gentili, 1980 from Guizhou for the first time. Additionally, an identification key to Laccobius (Glyptolaccobius) of the world is updated.

The bombyliid genus Marmasoma White is restricted to Australia. Marmasoma sumptuosum White, the only known species of the genus, is studied and a lectotype and paralectotypes are designated. Based on the type series and on additional material, a redescription of the species is presented and the main characters of the external morphology of adults are illustrated and photographed, including male and female genitalia. In addition, the remarkable aedeagus of M. sumptuosum, unique among all Ecliminae species by the presence of serrated projections on its apical portion, is described and photographed in detail for the first time. An identification key to the Australasian/Oceanian genera of Ecliminae and a distribution map with the known geographic records of Marmasoma are also included.

ABSTRACT Euphorbiaceae is one of the richest families in the State of São Paulo, with 37 genera and around 150 species. A synopsis of Astraea was published as part of the treatment for the tribe Crotoneae, but recent taxonomic and systematic advances have brought a more refined knowledge about the genus, especially for the widespread Astraea lobata. This species had its morphological delimitation poorly defined until very recently and, as a result, about five species were distinguished based on morphological characters. In this work, we update the synopsis of Astraea as part of the taxonomic revision of the genus and studies on Euphorbiaceae for the Flora Fanerogâmica do Estado de São Paulo project. We present an identification key, photographs of diagnostic characters, and an updated distribution map for the five species of Astraea found in São Paulo, along with a list of specimens for the state.

Tyranonoseira is revised and new diagnostic characters to the genus and its species are proposed. The genus is now characterised by distinct chaetotaxic patterns of head, in lacking M2, S1, S4, S5 macrochaetae and Th II to Abd IV with 21–27, 7, 0, 3, 1 and 8–10 central macrochaetae, as well as anterior legs of males with modified chaetae. The five species of the genus are redescribed based on type material: T. raptora Zeppelini & Bellini, T. bicolorcornuta Bellini & Zeppelini, T. diabolica Bellini & Godeiro, T. gladiata Zeppelini & Lima and T. sex Bellini & Zeppelini. We include an identification key and comparison of the species. The dorsal chaetotaxy is similar for all species. Characters omitted from the original descriptions such as chaetotaxy of the clypeus, labral papillae, collophore chaetae and manubrial formula are now used to distinguish species more clearly. We compare the morphology of Seira and Tyrannoseira using dorsal chaetotaxy and the modified chaetae on anterior legs of males.

We present a comprehensive taxonomic revision of the Mecistocephalidae occurring in the Japanese main archipelago and in Taiwan, based on both the critical analysis of published information and the comparative morphological examination of representative specimens, including type material. A total of 34 species in 8 genera are recognised. Diagnostic characters, synonyms and geographical distribution are reviewed and discussed for all species, and a detailed redescription is provided for 12 already known species. An identification key to all species is also provided. The following species are described as new: Arrup ishiianus, Arrup lilliputianus, Arrup longicalix, Arrup kyushuensis, Mecistocephalus changi, Mecistocephalus karasawai. The following synonymies are new: Tygarrup monoporus Shinohara, 1961 = Dicellophilus pulcher (Kishida, 1928); Mecistocephalus fenestratus Verhoeff, 1934 = Mecistocephalus japonicus Meinert, 1886; Mecistocephalus insulomontanus Gressitt, 1941 = Mecistocephalus marmoratus Verhoeff, 1934; Mecistocephalus manazurensis Shinohara, 1961 = Mecistocephalus nannocornis Chamberlin, 1920; Mecistocephalus mirandus Pocock, 1895 = Mecistocephalus japonicus Meinert, 1886; Mecistocephalus okinawaensis Takakuwa, 1939 = Mecistocephalus pauroporus Takakuwa, 1936; Mecistocephalus takakuwai Verhoeff, 1934 = Mecistocephalus diversisternus (Silvestri, 1919). Dicellophilus pulcher (Kishida, 1928) new comb. is here recognised as the valid name for the species previously referred to as Dicellophilus latifrons Takakuwa,1934.

The taxonomy of the widespread camel spider, Rhagodes eylandti (Walter, 1889), is herein updated and revised by proposing three nominal taxa as its junior synonyms. These are based on data from males of two taxa, Rhagodes melanopygus nigricans Birula, 1905 and R. plumbescens (Walter, 1889), and a female of R. melanochaetus Heymons, 1902. Consequently, both sexes of R. eylandti are re-described and the validity of their morphological diagnostic characters is evaluated. Detailed morphological and morphometrical characters, as well as data on sexual dimorphism and intraspecific variations, are provided. The illustrations of type material are given for the first time. Moreover, a distribution map and ecological notes are presented.

The orchid genus Phloeophila is distributed from southern Mexico to Brazil and Bolivia, as well as Cuba. A taxonomic revision including the three Phloeophila species present in Ecuador is presented. Morphological characteristics, an identification key, maps of known localities and illustrations of the species are also included. In Ecuador, species of Phloeophila are only known from the Amazonian rainforests, growing from 890 to 1600 meters of altitude. Phloeophila condorana is described as a new species based on specimens collected in the Ecuadorian province of Zamora-Chinchipe and compared to Phloeophila nummularia. Phloeophila nummularia is reported for the first time in Peru. A lectotype for Pleurothallis echinantha is selected.

The Neotropical genus Pygodiscodon Wittmer, 1966 (Coleoptera: Cantharidae: Silinae: Silini) is revised. Six species are recognized as valid, three of which are herein proposed as new: Pygodiscodon apicicornis (Pic, 1910), P. gurupi sp. nov., P. monoceros sp. nov., P. obscurus Wittmer, 1966, P. similis sp. nov., and P. touroulti Constantin, 2010. Pygodiscodon obscurus, currently synonymized with P. apicicornis, is herein revalidated. A lectotype is designated for P. apicicornis. Pygodiscodon apicicornis and P. touroulti are recorded for the first time in Guyana and Suriname, and Brazil respectively. An identification key and a distributional map for the species are provided.

The genus Ludioctenus Fairmaire, 1893 hitherto included only L. cyprius (Baudi di Selve, 1871) from the eastern Mediterranean and L. pakistanicus Schimmel & Tarnawski, 2012 from Pakistan. Here, we describe L. afghanicus sp. nov. from the Nuristan Province in eastern Afghanistan. The distribution and morphological diversity of Ludioctenus is discussed, main diagnostic characters for all species are figured, and an identification key to the species of this genus is provided. Female pregenital segments and genitalia are figured for the first time for Ludioctenus, and the systematic position of this genus and its relatives is discussed.
