We revise the species-level taxonomy of the Crematogaster (Crematogaster) degeeri-species-assemblage, a group of related ants occuring in Madagascar and the wider Malagasy region, and further provide an identification key to all species-groups of the genus Crematogaster in this region. Within the C. degeeri-assemblage, we recognize twelve species based upon morphological data from worker, queen and male ants, as well as genetic data from the barcode region of cytochrome oxidase I. Seven new species are described: Crematogaster alafara Blaimer sp. nov., C. bara Blaimer sp. nov., C. mafybe Blaimer sp. nov., C. maina Blaimer sp. nov., C. malahelo Blaimer sp. nov., C. masokely Blaimer sp. nov., C. ramamy Blaimer sp. nov. Crematogaster tricolor Gerstäcker, 1859 (stat. rev.) and C. dentata Dalla Torre, 1893 (stat. nov.) are raised to species level, and the following new synonymies are proposed: Crematogaster degeeri lunaris Santschi, 1928 as a synonym of C. degeeri Forel, 1886; Crematogaster sewelli improba Forel, 1907 and C. sewelli mauritiana Forel, 1907 as synonyms of C. dentata Dalla Torre, 1893, and C. pacifica Santschi, 1919 as a synonym of C. lobata Emery, 1895. Species descriptions, images, and distribution maps and identification keys based on worker ants, as well as on queen ants where available, are presented for all twelve species. In addition, we present a molecular gene tree for cytochrome oxidase I and summarize levels of sequence divergence within and between species of the C. degeeri-species-assemblage. Our findings are discussed in the light of previous work on Malagasy Crematogaster ants.

New World frogs recently placed in a single, enormous family (Brachycephalidae) have direct development and reproduce on land, often far away from water. DNA sequences from mitochondrial and nuclear genes of 344 species were analyzed to estimate their relationships. The molecular phylogeny in turn was used as the basis for a revised classification of the group. The 882 described species are placed in a new taxon, Terrarana, and allocated to four families, four subfamilies, 24 genera, 11 subgenera, 33 species series, 56 species groups, and 11 species subgroups. Systematic accounts are provided for all taxa above the species level. Two families (Craugastoridae and Strabomantidae), three subfamilies (Holoadeninae, Phyzelaphryninae, and Strabomantinae), six genera (Bryophryne, Diasporus, Haddadus, Isodactylus, Lynchius, and Psychrophrynella), and two subgenera (Campbellius and Schwartzius) are proposed and named as new taxa, 13 subspecies are considered to be distinct species, and 613 new combinations are formed. Most of the 100 informal groups (species series, species groups, and species subgroups) are new or newly defined. Brachycephalus and Ischnocnema are placed in Brachycephalidae, a relatively small clade restricted primarily to southeastern Brazil. Eleutherodactylidae includes two subfamilies, four genera, and five subgenera and is centered in the Caribbean region. Craugastoridae contains two genera and three subgenera and is distributed mainly in Middle America. Strabomantidae is distributed primarily in the Andes of northwestern South America and includes two subfamilies, 16 genera, and three subgenera. Images and distribution maps are presented for taxa above the species level and a complete list of species is provided. Aspects of the evolution, biogeography, and conservation of Terrarana are discussed.

We compared sequences of the mitochondrial cytochrome oxidase I gene of eight species of the Bactrocera tau complex using Bactrocera dorsalis,Bactrocera pyrifoliae,Ceratitis capitata, Anopheles gambiae, and Locusta migratoria as outgroups. A 639-bp variable region was sequenced. The sequence divergence between species in the B. tau complex ranged from 0.06 to 28%, and up to 29% between the complex and its tephritid outgroups, B. dorsalis and C. capitata. According to the phylogenetic relationships, these members of the B. tau complex could be classified into four clades. Thus, species A and D form clades 1 and 3, respectively, while species C and I belong to clade 4. However, species B, E, and F form a distinct group, clade 2, and infested the fruits of non-cucurbit hosts. Host-plant shifts resulting in adaptive radiation and premating isolation among species might play an important role in species differentiation of the B. tau complex.Key words: Bactrocera, cytochrome oxidase I, species complex, mitochondrial DNA, phylogeny.

The 16 world species of Sphecomyia Latreille are revised, including seven previously undescribed species (S.cryptica Moran, sp. n., S.hoguei Moran, sp. n., S.interrupta Moran, sp. n., S.oraria Moran, sp. n., S.pseudosphecomima Moran, sp. n., S.sexfasciata Moran, sp. n., and S.weismani Moran, sp. n.). Descriptions, redescriptions, male genitalia photographs, distribution maps, and an illustrated key for all Sphecomyia are presented. DNA barcode data are provided for all 16 species with a cytochrome oxidase subunit I gene tree presented and discussed. Sphecomyiastat. rev. is redefined to represent the monophyletic lineage of species within subtribe Criorhinina possessing a bare, medial vitta extending ventrally from the oral margin in both sexes, a bare gena, a bare katepimeron, a scutellum with at least anterior margin densely pruinose, an anterior ventral half of vein C before crossvein h without setae, and a narrow intersection of vein R1 with vein C. Three species groups of Sphecomyia are identified: the S.vittata group which possess pruinose scutellar vittae, the S.pattonii group which lack pruinose scutellar vittae, and S.metallica (Bigot), a hairy bee mimic with a completely pruinose scutum. Criorhinatsherepanovi Violovitsh is resurrected and transferred, along with Criorhinaaino Stackelberg, to the genus Sphecomyia: S.tsherepanovi (Violovitsh), comb. n. and S.aino (Stackelberg), comb. n.Criorhinametallica (Bigot) is designated as the senior synonym of C.lupina (Williston), not junior as improperly treated, and transferred to Sphecomyia: S.metallica (Bigot), comb. n. The species Sphecomyiafusca Weisman, S.nasica Osburn, and S.occidentalis Osburn are transferred to Criorhina Meigen: C.fusca (Weisman), comb. n., C.nasica (Osburn), comb. n., and C.occidentalis (Osburn), comb. n.

The tribe Sisyphini sensu stricto Mulsant, 1842 comprises only three genera, the widespread Sisyphus Latreille, 1807 and Neosisyphus Müller, 1942, and the Mauritius endemic, Nesosisyphus Vinson, 1946. In southern Africa, Sisyphus and Neosisyphus are represented by five species groups in each genus. Together, they comprise a total of 33 valid species, of which six are new: Sisyphus auricomus sp. n; Sisyphus australis sp. n ; Sisyphus bicuariensis sp. n; Sisyphus inconspicuus sp. n; Sisyphus swazi sp. n; and Neosisyphus tembyi sp. n. A further Southern African species, Sisyphus crispatus Gory, 1833, is proposed as a nomen dubium. Sisyphus natalensis Balthasar, 1968 (syn. n), and Sisyphus bornemisszanus Endrödi, 1983 (pars) (syn. n) are made synonyms of Sisyphus sordidus Boheman, 1857. Lectotypes and paralectotypes are designated for Sisyphus costatus (Thunberg, 1818); Sisyphus seminulum Gerstaecker, 1871; Sisyphus nanniscus Péringuey, 1901; Sisyphus transvaalensis Péringuey 1901; Neosisyphus spinipes (Thunberg, 1818) and Neosisyphus barbarossa (Wiedemann, 1823). Diagnoses, photographs of habitus and male genitalia, lists of examined material and distribution maps are presented for all species. An identification key to the southern African sisyphine species is provided.

The Australian Anthracini are revised. In all, 28 new species are described, bringing the total fauna to 34 species. The previously described species of Anthrax Scopoli – A. maculatus Macquart, A. incomptus Walker, A. confluensisRoberts, A. lepidiotus Roberts and A. proconcisus Hardy – are diagnosed and the following eight new species of Anthrax are described: A. argentia, A. asciculus, A. clinatus, A. crenatus, A. dolabratus, A. funestus, A. opacus and A. torulus. This taxonomic study reveals a group of at least 20 cryptic species previously included in collections under the name Anthrax angularis Thomson. A new genus, Thraxan, is erected to contain this cryptic group of species and the following 20 new species are described: T. acutus, T. abditus, T. caligneus, T. cinctus, T. cornuatus, T. depressus, T. echinatus, T. ebenus, T. emicatus, T. hamulus, T. luteus, T. misatulus, T. nodus, T. norrisi, T. obstipus, T. patielus, T. planus, T. prolatus, T. simulatusand T. spiculus. Many of these cryptic species have been collected sympatrically, hill topping together in eastern Australia. A key is provided to the species of Anthrax and Thraxan, genitalia drawings are presented for most species and distribution maps of all species are presented. A cladistic analysis of the species of Anthrax and Thraxan is also presented. A total of 26 of the species is compared for 125 synapomorphies in 39 adult morphological characters. Three species-groups were found: Thraxan, and two species-groups within Anthrax, the A. proconcisus species-group and the A. maculatusspecies-group. Previous authors divided Anthrax into species-groups on the basis of wing patterns, but found that these species-groups were not confirmed when other characters were taken into consideration. We studied the congruence of seven different character sets within the clade comprising Anthrax and Thraxan – antennae, venation, wing patterns, vestiture, genitalia, male genitalia and female genitalia – using several incongruence indices. Significance of incongruence was measured using a randomisation procedure. Results of these studies indicate that the wing-pattern character set is significantly incongruent with the other morphological data. These quantitative cladistic results explain the difficulty previous authors experienced in finding suites of characters to support species-groups in Anthrax on the basis of wing patterns. A relationship is found between the level of incongruence and the distance over which mate-recognition signals operate.

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 genus Salvadora has not been subjected to a modern phylogenetic analysis. Described in 1853, its taxonomic history is complex and confusing. In this study, we evaluate the monophyly of the genus and present the first phylogenetic hypothesis based on an analysis of 66 qualitative and quantitative morphological characters of over 1000 specimens representing all described taxa across their entire distribution. Morphological characters were processed in Fast Morphology for subsequent phylogenetic analysis in PAUP under the maximum parsimony criterion. We obtained a single tree in which Salvadora appears as a monophyletic group with two clearly defined geographic species groups: a southern mexicana group and a northern grahamiae group. Based on our phylogenetic hypothesis, we evaluate the taxonomic status of all described taxa. Additionally, we include a diagnosis for all species, distribution maps, and an illustrated dichotomous taxonomic key of the genus.

This revision focuses on the genus Calleida Latreille, 1824 (in the widest sense) in the Oriental Region, previously treated as genus or subgenus Callidiola Jeannel, 1949. In the present contribution, as first part of a series of revisions of the Asiatic Calleida species, we define nine species groups including all known Asiatic species, based on external features and morphological characters of male and female genitalia. A key for the identification of all nine species groups is provided, along with diagnostic characters, included species, geographical distribution, and brief discussion on monophyly and relationships for each species group. In particular, the present contribution deals with species of six small species groups, including eleven species in total, for which keys to all known species, descriptions, distribution maps, habitus images and genitalia illustrations are provided.Five new species are described: Calleida gressittiana Casale & Shi, sp. n. (type locality: Kinabalu, Sabah, Borneo), Calleida puncticollis Shi & Casale, sp. n. (type locality: Zigui, Hubei), Calleida jelineki Casale & Shi, sp. n. (type locality: Coimbatore, India), Calleida viet Casale & Shi, sp. n. (type locality: Vung Tau, Vietnam), Calleida borneensis Shi & Casale, sp. n. (type locality: Sabah, Borneo). Lectotypes for five taxa are designated. One synonymy is newly proposed: Calleida lieftincki Louwerens junior synonym of Calleida corporaali Andrewes, syn. nov.

The Camponotus grandidieri species group and Camponotus niveosetosus species group of the Malagasy region are revised. Species delimitation was inferred from the evidence of both qualitative morphological analysis and multivariate morphometry. The multivariate method combined the Nest Centroid (NC)-clustering method and Partitioning Algorithm based on Recursive Thresholding (PART) function to generate hypotheses about species boundaries (clusters) based on 19 continuous morphological traits of minor workers. The proposed species hypotheses were tested by cumulative cross-validated Linear Discriminant Analysis (LOOCV-LDA) and Principal Component Analysis in a shape space (shape PCA). Morphometric ratios for the subsets of minor and major workers were used in species descriptions and redefinitions. Here, eight species are recognized, of which three are newly described and five are redescribed. Four species belong to the Camponotus grandidieri species group: auropubens Forel, efitra n. sp., grandidieri Forel, and maintikibo n. sp.; and four species belong to the Camponotus niveosetosus species group: descarpentriesi Santschi, madagascarensis Forel stat. rev., mita n. sp., and voeltzkowii Forel. Camponotus auropubens aldabrensis Forel and C. olivieri freyeri Santschi are synonymized under C. auropubens. Camponotus grandidieri atrabilis Santschi and C. grandidieri comorensis Santschi are synonymized under C. grandidieri. Illustrated species identification keys for both minor and major castes, taxonomic discussions, images, and distribution maps for each species superimposed on the ecoregions of Madagascar are also provided.
