The genus Copelatus Erichson, 1832 (Coleoptera, Dytiscidae, Copelatinae) of Madagascar is revised in two parts. This review is restricted to the Copelatus species that have fewer than ten elytral + one submarginal stria, including all species except those of the erichsonii species group. Both morphological and molecular (mitochondrial COI) data are used in an integrative taxonomic approach. Thirteen species are recognised, of which five are described as new: Copelatus ankaratrasp. nov., Copelatus kelysp. nov., Copelatus pseudostriatussp. nov., Copelatus safiotrasp. nov. and Copelatus vokokasp. nov.Copelatus unguicularis Régimbart, 1903 and Copelatus apicalis Fairmaire, 1898 are both transferred to the genus Madaglymbus Shaverdo & Balke, 2008 (comb. nov.). Copelatus mimetesGuignot 1957 is a junior synonym of the widespread Afrotropical–Arabian Copelatus pulchellus (Klug, 1834) (syn. nov.). Copelatus marginipennis (Laporte, 1835) is reinstated (stat. nov.) as a valid species with Copelatus aldabricus Balfour-Browne, 1950 and Copelatus aldabricus var. simplex Guignot, 1952 as junior synonyms (syn. nov.). We designate lectotypes for Colymbetes marginipennis Laporte, 1835 and Copelatus obtusus Boheman, 1848. Copelatus peridinus Guignot, 1955 is recorded for Madagascar for the first time and Copelatus nodieri Régimbart, 1895 is rejected as a species present in Madagascar.

The present study represents a taxonomic revision of the Pheidole sikorae species group from Madagascar. Forty-four members of this group are recognised and described, and an illustrated identification key to this group is also presented. One species is raised to species level: P. litigiosa Forel, 1892 stat. nov.Pheidole veteratrix angustinoda Forel, 1892 syn. nov. is proposed as a junior synonym of Pheidole veteratrix Forel, 1891. Worker castes are also described and lectotypes designated for P. litigiosa Forel, 1892, P. sikorae Forel, 1891, and P. veteratrix Forel, 1891. The following 41 new species are described: P. alinasp. nov., P. ambohimangasp. nov., P. analavelonasp. nov., P. andohahelasp. nov., P. anomalasp. nov., P. anosyennesp. nov., P. antranohofasp. nov., P. beankasp. nov., P. befotakasp. nov., P. dasossp. nov., P. flavominutasp. nov., P. gracilissp. nov., P. habokasp. nov., P. havoanasp. nov., P. hazosp. nov., P. itremosp. nov., P. joffrevillesp. nov., P. kelysp. nov., P. lavasoasp. nov., P. mahamavosp. nov., P. maintysp. nov., P. mamiratrasp. nov., P. mananteninasp. nov., P. masoandrosp. nov., P. mavohavoanasp. nov., P. midongysp. nov., P. mikrossp. nov., P. mivorysp. nov., P. nitidobrunasp. nov., P. parvulasp. nov., P. parvulogibbasp. nov., P. reniranosp. nov., P. savasp. nov., P. sofiasp. nov., P. sparsasp. nov., P. tamponysp. nov., P. trichotossp. nov., P. tsaravonianasp. nov., P. vadumsp. nov., P. volontanysp. nov., and P. vonysp. nov. At present, there are 109 valid species and subspecies of Pheidole known from Madagascar, but this number is expected to increase with upcoming taxonomic revisions of the species groups not revised in this study.

The Empria longicornis species group (Hymenoptera, Tenthredinidae) is revised. Empria japonica Heidemaa & Prous, sp. nov. is described from Japan. The lectotypes of Empria gussakovskii Dovnar-Zapolskij, 1929, E. konowi Dovnar-Zapolskij, 1929, Poecilosoma longicornis Thomson, 1871, P. mongolica Konow, 1895, and P. tridens Konow, 1896 are designated. Empria konowi Dovnar-Zapolskij, 1929 (syn. nov.) and E. gussakovskii Dovnar-Zapolskij, 1929 (syn. nov.) are synonymized with E. tridens (Konow, 1896), and Empria waldstaetterense Liston, 1980 (syn. nov.) with E. alector Benson, 1938. Empria alpina Benson, 1938 and E. minuta Lindqvist, 1968, earlier misidentified as E. gussakovskii, are treated as valid species. Nine species are confirmed to belong in the longicornis-group: E. alector, E. alpina, E. basalis, E. japonica, E. loktini, E. longicornis, E. minuta, E. mongolica, and E. tridens. Distributional data of the species and a key to the imagines are provided. Ex ovo rearings of the four most common and often misidentified species in the group (E. alector, E. basalis, E. longicornis, and E. tridens) were carried out to verify their host plants and male conspecifics. External morphology, morphometrics (geometric and traditional), and DNA sequences (mitochondrial COI and nuclear ITS1 and ITS2) are used to delimit species within the group and to assess their phylogenetic relationships. Mitochondrial DNA sequences analyzed are mostly regarded as unsuitable for species circumscription, DNA barcoding and for reconstructing species phylogeny within the group. In this regard, analyses of the ITS sequences yielded more concordant results.

The taxonomy of the American Onthophagus Latreille, 1802 included in the “hirculus” group is revised, and a study of their morphology allows for the delineation of five species-complexes. Herein, we provide a diagnosis of the “hirculus” group, an illustrated key to the complexes, along with a descriptive overview of their taxonomy and geographic distribution. Onthophagus hirculus Mannerheim, 1829 is considered to be a junior synonym of O. hircus Billberg, 1815, which is here demonstrated to be a valid species name. Thus, the “hirculus” group is here renamed the “hircus” group. Furthermore, a general scheme of the genital organs of American Onthophagus is provided, including names of different anatomical parts and a brief discussion on the need for nomenclatural stability for the genitalia of scarab beetles.

The ant genus Prionopelta Mayr, 1866 is revised for the Neotropics. Morphological traits combined with geographical data led to the recognition of eight species, four of them described here as new: Prionopelta dubia sp. n., Prionopelta menininha sp. n., Prionopelta minuta sp. n., and Prionopelta tapatia sp. n. Prionopelta marthae Forel, 1909 is proposed as a new junior synonym of Prionopelta antillana Forel, 1909. External morphological descriptions of the worker caste for all species are provided, as well as for some of the males and queens, mostly described here for the first time. Identification keys for all known castes, distribution maps and high-resolution illustrations are supplied for all species.

A taxonomic revision of the tribe Ceroptresini (Hymenoptera: Cynipidae) is conducted for the first time. Prior to this study, the total number of valid species of Ceroptres, the only genus within Ceroptresini to date, was 23. As a result of this revision, 15 Ceroptres species are retained as valid and one species, Amblynotus ensiger Walsh, 1864, is desynonymized from Ceroptres petiolicola (Osten-Sacken, 1861), being considered here as a valid Ceroptres species: C. ensiger (Walsh, 1864) status verified and comb. nov. An additional five new species are described from Mexico: Ceroptres junquerasi Lobato-Vila & Pujade-Villar sp. nov.; C. lenis Lobato-Vila & Pujade-Villar sp. nov.; C. mexicanus Lobato-Vila & Pujade-Villar sp. nov.; C. nigricrus Lobato-Vila & Pujade-Villar sp. nov.; C. quadratifacies Lobato-Vila & Pujade-Villar sp. nov., increasing the total number of valid Ceroptres species to 21. Ceroptres masudai Abe, 1997 is synonymized with C. kovalevi Belizin, 1973. Ceroptres niger Fullaway, 1911 is transferred to Andricus (Andricus confusus Lobato-Vila & Pujade-Villar comb. nov. and nom. nov.). Five species (Amblynotus inermis Walsh, 1864; Cynips quercusarbos Fitch, 1859; Cynips querficus Fitch, 1859; Cynips quercuspisum Fitch, 1859; and Cynips quercustuber Fitch, 1859) are not considered as valid Ceroptres. The status of Ceroptres quereicola (Shinji, 1938), previously classified as an unplaced species, is commented on. In addition, a Nearctic species from the USA, Ceroptres politus Ashmead, 1896, is here proposed as the type species of a new genus within Ceroptresini: Buffingtonella Lobato-Vila & Pujade-Villar gen. nov. Redescriptions, biological and distribution data, illustrations and keys to genera and species within Ceroptresini are provided. The diagnostic morphological traits of Ceroptresini, Ceroptres and the new genus are discussed.

Abstract The combination of genetic and phenotypic characters for species delimitation has allowed the discovery of many undescribed species of Neotropical amphibians. In this study, we used DNA sequences (genes 12S, 16S, ND1 and COI) and morphologic, bioacoustic and environmental characters of the Boana semilineata group to evaluate their phylogenetic relationships and assess their species limits. In addition, we included DNA sequences of several species of Boana to explore cryptic diversity in other groups. We found three Confirmed Candidate Species (CCS) within the B. semilineata group. Holotype examination of Hyla appendiculata shows that it is a valid species that corresponds to one of the CCS, which is here transferred to Boana. We describe the two remaining CCS. Our phylogeny highlights a number of secondary but meaningful observations that deserve further investigation: (1) populations of B. pellucens from northern Ecuador are more closely related to B. rufitela from Panama than to other Ecuadorian populations of B. pellucens; (2) we report, for the first time, the phylogenetic relationships of B. rubracyla showing that it is closely related to B. rufitela and B. pellucens; and (3) B. cinerascens and B. punctata form two species complexes consisting of several unnamed highly divergent lineages. Each of these lineages likely represents an undescribed species.

The Relationship

The Afrotropical representatives of the hoverfly genus Phytomia Guérin-Méneville (Diptera) are revised. In total, 19 species are recognized of which three are new to science: Phytomia austeni sp. nov., P. memnon sp. nov., and P. pallida sp. nov. Phytomia neavei Bezzi is considered a junior synonym of P. kroeberi (Bezzi), P. noctilio Speiser a junior synonym of P. pubipennis Bezzi, and P. ephippium Bezzi a junior synonym of P. melas (Bezzi). Lectotypes are designated for the following species: Megaspis bulligera Austen, Megaspis erratica Bezzi, and Megaspis poensis Bezzi. In addition, unpublished lectotype designations are hereby formally published for the following species: Megaspis bullata Loew, Megaspis curta Loew, and Megaspis capito Loew. Phytomia curta (Loew) is considered a valid species, and differentiated from P. natalensis (Macquart). Phytomia fronto Loew is tentatively considered to belong to the genus Simoides Loew. The relationship between the different Phytomia species, as well as the relationship between Phytomia and Simoides, is briefly discussed based on morphological and DNA data.

Host Utilization

Seven of the 13 described species of this gregarious, polyphagous, polymorphic parasitoid have been placed in the acasta species group of Melittobia Westwood (Hymenoptera: Eulophidae: Tetrastichinae) based on ethological and morphological criteria, but taxonomic confusion remains. Based on field and laboratory studies of variability and polymorphism, current species descriptors for this group are called into question and Melittobia femorata Dahms is synonymized under M. megachilis (Packard). Biologically, M. megachilis distinctly differs from other acasta group species in several aspects of life cycle and host utilization. Although M. acasta (Walker) and M. digitata Dahms are clearly valid species, three others (M. chalybii Ashmead, M. scapata Dahms, M. evansi Dahms) are more enigmatic and may be temporal, nutritional, or host-based variants of M. megachilis that will require additional study. The “Virginia” type locality for M. chalybii of authors is properly Bladensburg, Maryland, USA. One of the 13 female syntypes of Chrysocharis aeneus Brues (previously synonymized under M. megachilis) is designated as Lectotype.

Magulla janeirus (Keyserling 1891) is considered a valid species. Magulla symmetrica Bücherl 1949 is transferred to Plesiopelma Pocock 1901, and considered a junior synonym of P. insulare (Mello-Leitão 1923). Additionally, two new species are described from Brazil: M. buecherli n. sp. from Ilhabela, São Paulo and M. brescoviti n. sp. from São Francisco de Paula, Rio Grande do Sul.

The Elachista bedellella Sircom complex is diagnosed and its taxonomy is revised. The female genitalia, when known, are found to be of good diagnostic value in defining species. In the male genitalia there are subtle, yet decipherable interspecific differences in the shape of the juxta and the cornutus that correlate with differences in the outer appearance of different populations. As a result, eight species are recognised, including the following new species: Elachista antonia sp. n. from Greece (Crete), E. slivenica sp. n. from Bulgaria, E. dorinda sp. n. from Turkey, E. versicolora sp. n. from Russia (Transbaikalia) and E. camilla sp. n. from Russia (Kuray). The identity of E. lugdunensis Frey is clarified and it is considered a valid species, and E. coeneni Traugott-Olsen, 1985 is confirmed to be a junior synonym of it. E. bedellella, E. lugdunensis and E. titanella Kaila & Jalava, 1994 (stat. n.) are diagnosed and illustrated.
