The Neotropical genus Rhyacopsyche Müller, 1879, was last reviewed in 1971 when 5 species were known. Since that time, the genus has gradually grown to 13 species: R. andina Flint, 1991 (Colombia, Peru, Venezuela), R. chichotla Bueno & Hamilton, 1986 (Mexico), R. duplicispina Flint, 1996 (Tobago), R. hagenii Müller, 1879b (Argentina, Brazil, Uruguay), R. jimena Flint, 1991 (Colombia), R. matthiasi Flint, 1991 (Colombia), R. mexicana (Flint, 1967) (Costa Rica, Guatemala, Mexico, Nicaragua), R. mutisi Mey & Joost, 1990 (Colombia), R. obliqua Flint, 1971 (Mexico), R. peruviana Flint, 1975 (Ecuador, Peru), R. torulosa Flint, 1971 (Costa Rica, Guatemala), R. turrialbae Flint, 1971 (Costa Rica), and R. yatay Angrisano, 1989 (Argentina). Thirteen new species are described and illustrated: R. benwa (Bolivia, Ecuador, Peru), R. bulbosa (Brazil), R. colei (Venezuela), R. colombiana (Colombia), R. colubrinosa (Ecuador, Peru), R. dikrosa (Brazil), R. flinti (Venezuela), R. hasta (Peru), R. intraspira (Peru), R. otarosa (Venezuela), R. patulosa (Brazil), R. rhamphisa (Colombia, Costa Rica), and R. tanylobosa. (Ecuador, Peru, Venezuela). The distribution of Rhyacopsyche is widened to include Bolivia and Nicaragua. Detailed illustrations are presented for all species as well as diagnoses, descriptions, and a taxonomic key. A species level phylogenetic analysis using PAUP* 4.0b 10 was performed. A heuristic search was conducted based on 20 morphological characters of the male genitalia, with species of Ochrotrichia and Metrichia used as outgroups. A strict consensus of 23 equally parsimonious trees is presented. The analysis revealed 3 characters supporting the monophyly of Rhyacopsyche. The monophyly of 1 of the 2 previously established species groups, the turrialbae group, is supported.

A New Species

The Afrotropical genus Pegylis Erichson, 1847 (Coleoptera: Scarabaeidae: Melolonthinae: Pegylini) was recently treated by Lacroix (2015), who keyed and figured most of the known species and divided the genus into six species groups based on the number of antennomeres, shape of male genitalia and number of teeth on the protibia. Unfortunately, Lacroix (2015) overlooked two earlier papers by Harrison (2014a, 2014b). Harrison (2014a, 2014b) provided a phylogenetic analysis of the tribe, synonymised Hypopholis Erichson, 1847 with Pegylis, and redescribed the three known South African species of Pegylis. Based on these papers, the genus Pegylis currently contains 37 species.

The Old World water scavenger beetle genus Sternolophus Solier is revised. Six new species are described: Sternolophus acutipenis sp. n., S. insulanus sp. n., S. jaechi sp. n., S. mandelai sp. n., S. prominolobus sp. n. and S. solitarius sp. n. Three taxa are reinstated as valid species: Sternolophus angustatus (Boheman), S. elongatus Schaufuss and S. mundus (Boheman). The subgenera within the genus are rejected and Neosternolophus Zaitzev syn. n. is synonymized with Sternolophus s. str. Lectotypes are designated for Hydrophilus angolensis Erichson, H. angustatus, H. rufipes Fabricius, Sternolophus brachyacanthus Régimbart, S. comoriensis Fairmaire, S. elongatus, S. frater Schaufuss, and S. rufipes var. foveoliceps Kolbe. On the basis of similar morphological characters, two species-groups are proposed for some of the species within the genus: The angolensis group including S. angolensis, S. inconspicuus (Nietner), S. mundus, and S. solitarius, and the solieri group including S. angustatus, S. elongatus, S. mandelai, S. rufipes Fabricius, and S. solieri Castelnau. Sternolophus unicolor (Castelnau) is considered a nomen dubium. Male genitalia and other diagnostic morphological characters are illustrated, and distribution maps are presented for all 17 species.

World representatives of the genus Arganthomyza Roháček, 2009 (Diptera, Anthomyzidae) are reviewed, keyed and their relationships are discussed on the basis of a phylogenetic analysis of morphological characters. The Nearctic species of Arganthomyza are revised, described and illustrated, and first data about their biology and distribution are given. Five new species, A. carbo sp. n. (Canada, USA), A. acuticuspis sp. n. (USA), A. bivittata sp. n. (Canada, USA), A. duplex sp. n. (Canada, USA) and A. disjuncta sp. n. (Canada, USA) are described and A. socculata (Zetterstedt, 1847) is newly recorded from the Nearctic Region (USA: Alaska). Based on the phylogenetic analysis, four main clades/species groups are recognized within Arganthomyza, represented by the following species: A. barbarista Roháček, 2009 (A. barbarista group); A. setiplanta (Roháček, 1987), A. versitheca Roháček, 2009 and A. carbo sp. n. (A. setiplanta group); A. acuticuspis sp. n., A. bivittata sp. n. and A. duplex sp. n. (A. duplex group); A. disjuncta sp. n. and A. socculata (Zetterstedt) (A. socculata group). Considering the contemporary distribution and relationships of Arganthomyza species, it is hypothesized that the A. barbarista group and A. setiplanta group originated in East Asia while the A. duplex group and the A. socculata group each has its origin in the Nearctic Region.

This revision of the cicadas of the genus Dilobopyga provides a diagnosis of the genus and descriptions, illustrations and distribution maps for 48 species. The following 33 species described here are new to science: D. angulata, angustata, bifida, curvispina, fasciata, hayashii, hollowayi, johani, knighti, langeraki, laterocurvata, latifascia, luwukensis, macrocerata, maleo, mamasa, mediolobata, nebulosa, operculata, palopoensis, pelengensis, platyacantha, quadrimaculata, rantemario, recurvata, rozendaali, sangihensis, sarasinorum, splendida, tambusisi, toraja, vantoli and watuwila. The key presented is designed for the identification of males of Dilobopyga to the species level. The subdivision of the genus in five species groups viz., opercularis group (17 species), nebulosa group (1 species), chlorogaster group (16 species), minahassae group (6 species) and watuwila group (8 species), is sustained by a phylogenetic analysis of morphological characters of all species described.        The cicadas of the genus Dilobopyga are found in Sulawesi, neighbouring islands and southern Moluccas. Of the 48 species of Dilobopyga 43 species are endemic to Sulawesi. Most of these Sulawesi species are restricted to either one peninsula or to a part of Central Sulawesi. The remaining five species are endemic to either the Sangihe Islands, Banggai Islands or the southern Moluccas. A taxon-area cladogram for the species of Dilobopyga provides a basis for a discussion on the historic biogeography of the genus.

The species belonging to the Sphodrine genus Laemostenus Bonelli, 1810 from central and southern Zagros Mts. and central zones of Iran were studied. Two new species-groups of the subgenus Antisphodrus Schaufuss, 1865 are proposed, and seven new species belonging to subgenera Antisphodrus Schaufuss, 1865 and Iranosphodrus Lohaj & Casale, 2011 are described. Morphological characters of the habitus and shape of male genitalia were used to delimit the species. New species of subgenus Antisphodrus are: L. (A.) zagrosensis sp. nov. and L. (A.) speleophilus sp. nov. from Chaharmahal and Bakhtiari province, and L. (A.) farsicus sp. nov. from Fars province (zagrosensis species-group); Laemostenus (A) zakariyiensis sp. nov. from Fars province (aequalis species-group), and L. (A.) shirazensis sp. nov. from Fars province (glasunowi species-group).  Based on the newly collected material, the subgenus Iranosphodrus is redefined and two new species from Yazd province are described: L.(I.) yazdensis sp. nov. and L.(I.) troglophilus sp. nov. An identification key for the Laemostenus species of the studied area is provided, and a check list for Iranian representatives of subgenera Antisphodrus and Iranosphodrus are given.

The genus Dragmatucha Meyrick is reviewed and 11 species of a total of 13 are described as new. The new species originate from the Democratic Republic of Congo, Ghana, Kenya, and Uganda. Based on morphological characters, especially the color pattern of both wings, the genus is divided into two species-groups: the proaula species-group with five species (D. proaula Meyrick, 1908; D. galbinea Park, sp. nov.; D. kabarolensis Park, sp. nov.; D. saltualis Park, sp. nov. and D. vittatella Park, sp. nov.) and the hispidula species-group with eight species (D. hispidula Park, 2018; D. goniotes Park, sp. nov.; D. cochliana Park, sp. nov.; D. pedalis Park, sp. nov.; D. ghanaensis Park, sp. nov.; D. crinifrutalis Park, sp. nov.; D. dizostera Park, sp. nov. and D. kakumensis Park, sp. nov.). Adults and male genitalia of all new species are illustrated, but female genitalia are provided only for D. ghanaensis Park, sp. nov. and D. kakumensis Park, sp. nov. When fresh material was available, the analysis of COI sequences was undertaken.

Abstract Rhinomirini (Insecta: Heteroptera: Miridae: Cylapinae) is a heterogeneous tribe of uncertain systematic position. We provide a phylogenetic analysis of this tribe based on morphological characters and molecular markers. Monophyly of the tribe was not supported by our findings. The Rhinocylapus complex and Rhinomiriella complex are transferred to Fulviini. Rhinomirini are restricted to the Rhinomiris complex. The record of Rhinomirini in Australia is considered dubious. The genera Punctifulvius and Yamatofulvus are transferred to the Rhinocylapus complex. The Rhinocylapus complex is recorded from Australia for the first time, with four new species: Mycetocylapus alexeyi sp. nov., Punctifulvius austellus sp. nov., Punctifulvius aquilonius sp. nov. and Rhinocylapoides valentinae sp. nov. The Philippine species Mycetocylapus major is synonymized with Mycetocylapus minor. The Australian species Rhinomiriella tuberculata is redescribed, and females of this species are described for the first time. Rhinomiriella aidani sp. nov. is described as new to science. The female genitalia of Proamblia elongata, Rhinocylapidius velocipidoides and Rhinomiris conspersus and the male genitalia of Rhinomiris conspersus and Rhinomiridius aethiopicus are illustrated and discussed. Sexual dimorphism in the Rhinocylapus complex and wing modifications in Cylapinae are discussed.

The taxonomy of the subgenus Ashima of the genus Phortica is revised. A cladistic analysis of 66 morphological characters is conducted, covering 35 species (28 known and 7 new species: Phortica efragmentata sp. nov., P. andreagigoni sp. nov., P. watabei sp. nov., P. halimunensis sp. nov., P. akutsui sp. nov., P. kerinciensis sp. nov., and P. takehiroi sp. nov.) which correspond to 71.4% of 49 total spp. of Ashima. The resulting cladogram shows that the studied species are separated into several clades/subclades/cluster each highly supported with specific synapomorphies. Those clades/subclades/cluster are newly defined as the following species groups, subgroups or complex: the afoliolata, foliiseta, nigrifoliiseta and angulata species groups; the foliiseta, tanabei, nigrifoliiseta and glabra species subgroups; and the foliiseta species complex. The subgenus Ashima is peculiar in having the asymmetric male genitalia as the ground plan and showing the antisymmetry (i.e. intraspecific mirror-image variation) in some species but the directional asymmetry (i.e. side-fixed asymmetry) in others. The evolution of genital asymmetry in this subgenus is estimated by mapping the states (symmetry, directional asymmetry and antisymmetry) of bilateral structures of male genitalia on the cladogram. This ancestral state reconstruction estimates that the directional asymmetry of male genitalia has evolved at the ancestor of this subgenus and then changed to the antisymmetric state independently in two lineages, the angulata + nigrifoliiseta species groups and the foliiseta species complex. In this study, a standardized terminology recently proposed for the male terminalia of Drosophila melanogaster is extendedly adopted to describe the morphology of male terminalia in the subgenus Ashima, one group of the subfamily Steganinae.
