With nearly 60 described forms Uromenus is the most species-rich genus of the tribe Ephippigerini, a west Palearctic group of flightless bush-crickets (katydids). As it is typical for bush-crickets, Uromenus males produce species-specific calling songs to attract females prepared to mate. These insects are relatively large and their songs have always components audible to humans. Nevertheless, acoustical information are available only for few species. Also the phylogenetic relationships of species and species groups are poorly known. In this paper we present new data on the song and morphology of several species (U. dyrrhachiacus, U. elegans, U. finoti, U. galvagnii, U. robustus, U. tobboganensis and U. innocentii) and give a review of all published acoustical data. Judging from the still few data, as in other Ephippigerini the song patterns often seem to contain species-group characteristics making them candidates to be used in phylogenetic studies. Additionally, we have studied the female stridulatory organs which are unique in structure in Ephippigerini and completely different from those of the males. Despite in Uromenus used only for defensive stridulation, possibly species-specific similarities in structure between males and females exist.

The Neotropical geometrine genus Oospila Warren, 1897 includes seventy-nine species and was revised by Cook & Scoble (1995). The genus is distinctive in having a row of raised abdominal crests, which are composed of specialized, erect, metallic shining scales. This paper focuses on the integrative morphological and molecular delimitation of the smallest Oospila species. The wing patterns and genitalia structures of males and females are illustrated. Cook & Scoble (1995) distinguished 13 species groups within Oospila. We discuss the species of the Oospila flavilimes species group, the O. stigma species group and O. miccularia species group below, and separate the O. arpata species complex into a group of its own. Nine new species and two new subspecies are described in this paper: O. cristae sp. n. from Ecuador, O. falcata sp. n. from French Guiana, O. pallidaria boliviensis subsp. n. from Bolivia, and O. loreenae sp. n. from Bolivia (flavilimes species group), O. ehakernae sp. n. from Costa Rica, O. similiplaga bolarpata subsp. n. from Bolivia (arpata species group), O. brehmi sp. n. and O. bifida sp. n. both from Bolivia, O. moseri sp. n. from Brazil, O. absaloni sp. n. and O. pipa sp. n. both from Ecuador (miccularia species group). Oospila similiplaga (Warren) (stat. nov.) is raised here from synonymy with O. arpata (Schaus) and O. imula (Dognin) from synonymy with O. miccularia (Guenée), respectively. Oospila agnetaforslundae nom. nov. is proposed as a replacement name for Oospila marginata Schaus, 1912 (nec Oospila marginata Warren, 1897), raising it to species rank from synonymy of Oospila permagna (Warren, 1909). With this paper, the number of Neotropical Oospila species is raised to 88.

A New Species

Eleven new species of the circum-tropical coral genus Acropora (Scleractinia : Astrocoeniina : Acroporidae) are described from material collected during a study of the biogeography of the genus worldwide. Previously known Indo-Pacific species of this genus mostly have broad distributions. The newly described species have been overlooked because they have more restricted distributions and in some cases they occur in deeper, rarely sampled, habitats; they thus contribute new information for assessment of the ecology and distribution patterns of the genus. Seven of the new species have low numbers of radial corallites relative to axial corallite number, a phenomenon uncommon amongst well-known (and widely distributed) species. It is suggested that this character would result in low reproductive output and may be responsible for the limited range of the species concerned. The new species are assigned to existing species-groups and a new species-group is suggested to accommodate two new species and three other valid species.

Antennular Peduncle

McLaughlin & Haig (1984) divided the genus Pagurixus Melin, 1939 in two informal species groups on the basis of the presence or absence of setal row(s) on the ventral surface of the ultimate segment of the antennular peduncle. The first group, characterized by the presence of the setal rows, is herein named the P. boninensis species group, and the second, characterized by the absence of setal rows, is named the P. anceps group. In this paper, species of the P. boninensis group are reviewed. Thirteen species are recognized in this species group, of which six are new: Pagurixus laevimanus (Ortmann, 1892), P. maorus (Nobili, 1906), P. boninensis (Melin, 1939), P. tweediei (Forest, 1956), P. festinus McLaughlin & Haig, 1984, P. nomurai Komai & Asakura, 1995, P. pulcher Osawa, Fujita & Okuno, 2006, P. brachydactylus n. sp. , P. carinimanus n. sp. , P. concolor n. sp. , P. paulayi n. sp. , P. pseliophorus n. sp.  and P. ruber n. sp.  These species are further arranged into two subgroups based on the presence or absence of a lateral ridge on the carpus of the left cheliped. The new species are fully described and illustrated. Redescriptions or updated descriptions and illustrations are given for each previously described species in order to facilitate comparisons. The affinities and important morphological variations of the species are discussed and their overall distributions are updated. Because of the sexual dimorphism exhibited by species of this genus, separate identification keys to males and females are presented.

Species Specific

Dissomphalus is a cosmopolitan genus of Bethylidae and has 269 Neotropical species divided into 32 species-groups, mostly defined by the genital and the tergal process structures. Dissomphalus rectilineus and D. concavatus are sympatric species in the ulceratus species-group. Members of the species-group share many similarities in the morphology of the head, hypopygium, tergal process and genitalia, but may be distinguished by the structure of the hypopygium. Previous studies have found intermediate structures of the hypopygium in the sympatric areas and raised questions about the distinctiveness of these two species. We sequenced 340 bp of the mitochondrial gene cytochrome oxidase I of 29 specimens from Brazil and Paraguay, calculated the genetic divergence among specimens, and recovered the phylogenetic relationships between taxa. In addition, we compared the morphology of the hypopygium to evaluate its use as a species-specific diagnostic character using the genetic divergence values. We recovered three well-supported monophyletic groups (intraclade divergence from 1.3 to 13.4%) and three hypopygium morphologies associated with each clade, two of them associated with D. rectilineus and D. concavatus (as described in the literature); the third one is new, not associated with any known species. The divergence between the D. rectilineus and D. concavatus clades was 19%, while the third clade is divergent from each species by 19–20%. If fully described, the hypopygium shape associated with the COI sequence will represent an extremely promising approach to the diagnosis of Dissomphalus species.

Within the genus Apiomerus Hahn, 1831, the crassipes and the pictipes species groups are described. In the crassipes species group, three species are redescribed: Apiomerus crassipes (Fabricius, 1803), Apiomerus rufipennis (Fallou, 1889) and Apiomerus spissipes (Say, 1825); one subspecies is raised to species level and redescribed: Apiomerus cooremani Costa Lima, Campos Seabra & Hathaway, 1951; and six species are described as new: Apiomerus californicus Berniker & Szerlip, sp. nov., Apiomerus cazieri Berniker & Szerlip, sp. nov., Apiomerus floridensis Berniker & Szerlip, sp. nov., Apiomerus montanus Berniker & Szerlip, sp. nov., Apiomerus peninsularis Berniker & Szerlip, sp. nov. and Apiomerus wygodzinskyi Berniker & Szerlip, sp. nov. In the pictipes species group, two species are redescribed, Apiomerus flaviventris Herrich-Schaeffer, 1846 and Apiomerus pictipes Herrich-Schaeffer, 1846, and one subspecies, Apiomerus pictipes pittieri Costa Lima, Campos Seabra, & Hathaway, 1951 is synonymized with Apiomerus pictipes. Neotypes are designated for Apiomerus flaviventris, Apiomerus pictipes, and Apiomerus spissipes. Lectotypes are designated for Apiomerus cooremani and Apiomerus crassipes. The composition of the species groups are different from those originally proposed by Sigurd Szerlip in his PhD dissertation. The crassipes group has one additional member, Apiomerus rufipennis. Furthermore, Apiomerus barrocoloradoi Forero, Berniker & Szerlip, 2010 and the two manuscript names “Apiomerus panther” and “Apiomerus tigris” were removed from the pictipes group. A key to the species is provided, as well as photographs of habitus and diagnostic features for both males and females. Intraspecific polychromatism is discussed as it relates to species identification and species delimitation.

Abstract Sepidiini is a speciose tribe of desert-inhabiting darkling beetles, which contains a number of poorly defined taxonomic groups and is in need of revision at all taxonomic levels. In this study, two previously unrecognized lineages were discovered, based on morphological traits, among the extremely speciose genera Psammodes Kirby, 1819 (164 species and subspecies) and Ocnodes Fåhraeus, 1870 (144 species and subspecies), namely the Psammodes spinosus species-group and Ocnodes humeralis species-group. In order to test their phylogenetic placement, a phylogeny of the tribe was reconstructed based on analyses of DNA sequences from six nonoverlapping genetic loci (CAD, wg, COI JP, COI BC, COII, and 28S) using Bayesian and maximum likelihood inference methods. The aforementioned, morphologically defined, species-groups were recovered as distinct and well-supported lineages within Molurina + Phanerotomeina and are interpreted as independent genera, respectively, Tibiocnodes Gearner & Kamiński gen. nov. and Tuberocnodes Gearner & Kamiński gen. nov. A new species, Tuberocnodes synhimboides Gearner & Kamiński sp. nov., is also described. Furthermore, as the recovered phylogenetic placement of Tibiocnodes and Tuberocnodes undermines the monophyly of Molurina and Phanerotomeina, an analysis of the available diagnostic characters for those subtribes is also performed. As a consequence, Phanerotomeina is considered as a synonym of the newly redefined Molurina sens. nov. Finally, spectrograms of vibrations produced by substrate tapping of two Molurina species, Toktokkus vialis (Burchell, 1822) and T. synhimboides, are presented.

Abstract A northward trans-Wallacean radiation is demonstrated for Chrysorthenches, a member of the Orthenches group. Here we review Chrysorthenches and allied genera resulting in a generic transfer of Diathryptica callibrya to Chrysorthenches and two new congeners: C. muraseaeSohn & Kobayashisp. nov. from Japan and C. smaragdinaSohnsp. nov. from Thailand. We review morphological characters of Chrysorthenches and allied genera, and find polyphyly of Diathryptica and the association of the Orthenches-group with Glyphipterigidae. These findings were supported in a maximum likelihood phylogeny of DNA barcodes from ten yponomeutoids. We analysed 30 morphological characters for 12 species of Chrysorthenches, plus one outgroup, via a cladistic approach. The resulting cladogram redefined two pre-existing Chrysorthenches species-groups and identified one novel lineage: the C. callibrya species-group. We review the host associations between Chrysorthenches and Podocarpaceae, based on mapping the working phylogenies. Our review suggests that ancestral Chrysorthenches colonized Podocarpus and later shifted to other podocarp genera. Biogeographical patterns of Chrysorthenches show that they evolved long after the Podocarpaceae radiation. Disjunctive trans-Wallacean distribution of the C. callibrya species-group is possibly related to the tracking of their host-plants and the complicated geological history of the island-arc system connecting Australia and East Asia.
