Teratopactus Heller (Entiminae : Naupactini) is a broad-nosed weevil genus widespread in South America. This first taxonomic revision of the genus includes seven species: T. capucinus (Perty) (type species; syn. T. senex (Boheman)); T. elegans (Lucas), comb.nov.; T. gibbicollis (Boheman); T. nodicollis (Boheman) (syn. T. angulicollis (Lucas), T. paulanus (Fonseca & Autuori), T. serripes (Boheman), and T. perpastus (Boheman), syn. nov.); T. retusus (Boheman); T. tuberculatus (Arrow); and T. vittatus (Mannerheim), comb.nov. All species except T. tuberculatus have a strong ovipositor lacking styli, T. elegans, T. nodicollis and T. vittatus show well developed humeri bearing a strong tooth and T. retusus, T. capucinus and T. gibbicollis are characterised by a strongly gibbous pronotum and reduced humeri. Teratopactus nodicollis is the most variable and widespread species (Argentina, Brazil, Bolivia, Paraguay and Uruguay), T. tuberculatus and T. elegans range through Brazil and Paraguay and the remaining species are endemic to Brazil. The first cladistic analysis of the genus Teratopactus plus two outgroups, using 36 morphological characters, established synapomorphies and revealed relationships between the species in a single cladogram with the following topology: (T. tuberculatus ((T. elegans (T. nodicollis– T. vittatus)) (T. retusus (T. capucinus–T. gibbicollis)))).

This study examines the phylogeny, taxonomy, distribution and biology of the gasteruptiid subfamily Hyptiogastrinae and, at the same time, presents an overview of the family. Following a cladistic analysis of 35 discrete morphological characters, two monophyletic genera are recognised, Hyptiogaster Kieffer and Pseudofoenus s. l. Kieffer. As a consequence, the genera Aulacofoenus Kieffer, Crassifoenus Crosskey, and Eufoenus Szépligeti are synonymised with Pseudofoenus. A total of 88 species are recognised for the subfamily, 10 species of Hyptiogaster, which are restricted to mainland Australia, and 78 species of Pseudofoenus, 40 of which are described as new. Pseudofoenus has a restricted Gondwanan distribution and is found in Australia including Tasmania (65 spp.), New Guinea and New Britain (5 spp.), the south-west Pacific (New Caledonia, New Hebrides and Fiji – 2 spp.), New Zealand (4 spp.) and South America (2 spp.). No new species have been recorded from either New Zealand or South America. For Pseudofoenus, information on the distribution of each species, their biology (if known) and an identification key are presented.Following a taxonomic revision, the following new species are described: P. baileyi, sp. nov., P. baitetaensis, sp. nov., P. beverlyae, sp. nov., P. caperatus, sp. nov., P. cardaleae, sp. nov., P. carrabinensis, sp. nov., P. claireae, sp. nov., P. collessi, sp. nov., P. coorowensis, sp. nov., P. crosskeyi, sp. nov., P. douglasorum, sp. nov., P. eliseae, sp. nov., P. ericae, sp. nov., P. eustonensis, sp. nov., P. feckneri, sp. nov., P. gressitti, sp. nov., P. gullanae, sp. nov., P. hackeri, sp. nov., P. imbricatus, sp. nov., P. iqbali, sp. nov., P. kadowi, sp. nov., P. karimuiensis, sp. nov., P. kelleri, sp. nov., P. leinsterensis, sp. nov., P. macdonaldi, sp. nov., P. malkini, sp. nov., P. marshalli, sp. nov., P. masneri, sp. nov., P. mitchellae, sp. nov., P. morganensis, sp. nov., P. nalbarraensis, sp. nov., P. pumilis, sp. nov., P. schmidti, sp. nov., P. stevensi, sp. nov., P. tasmaniensis, sp. nov., P. taylori, sp. nov., P. umboiensis, sp. nov., P. walkeri, sp. nov. and P. zborowskii, sp. nov. The synonymy of Aulacofoenus, Crassifoenus and Eufoenus with Pseudofoenus result in the following new combinations: from Aulacofoenus: P. bungeyi (Jennings & Austin), comb. nov., P. deletangi (Schletterer), comb. nov., P. fallax (Schletterer), comb. nov., P. fletcheri (Jennings & Austin), comb. nov., P. goonooensis (Jennings & Austin), comb. nov., P. infumatus (Schletterer), comb. nov., P. kurmondi (Jennings & Austin), comb. nov., P. loxleyi (Jennings & Austin), comb. nov., P. marionae (Jennings & Austin), comb. nov., P. perenjorii (Jennings & Austin), comb. nov., P. swani (Jennings & Austin), comb. nov., P. thoracicus (Guérin Menéville), comb. nov., P. whiani (Jennings & Austin), comb. nov. and P. wubinensis (Jennings & Austin), comb. nov.; from Crassifoenus: P. houstoni (Jennings & Austin), comb. nov., P. grossitarsis (Kieffer), comb. nov and P. macronyx (Schletterer), comb. nov.; and from Eufoenus: P. antennalis (Schletterer), comb. nov., P. australis (Westwood), comb. nov., P. crassitarsis (Kieffer), comb. nov., P. darwini (Westwood), comb. nov., P. extraneus (Turner), comb. nov., P. ferrugineus (Crosskey), comb. nov., P. floricolus (Turner), comb. nov., P. inaequalis (Turner), comb. nov., P. melanopleurus (Crosskey), comb. nov., P. minimus (Turner), comb. nov., P. nitidiusculus (Turner), comb. nov., P. patellatus (Westwood), comb. nov., P. pilosus (Kieffer), comb. nov., P. reticulatus (Crosskey), comb. nov., P. rieki (Crosskey), comb. nov., P. ritae (Cheesman), comb. nov. and P. spinitarsis (Westwood), comb. nov. Pseudofoenus microcephalus (Crosskey), comb. nov. is transferred from Hyptiogaster and Eufoenus flavinervis (Kieffer) remains incertae sedis.

A comprehensive taxonomic revision of the genus Notobubon (Apiaceae) is presented. Twelve woody evergreen species are recognised, all (with the exception of N. laevigatum) endemic to the Cape Floristic Region of South Africa. The taxonomy of these prominent, though poorly collected, species has until now been problematic. They are distinguished from one another by their habit (size and branching pattern), the overall shape, size, and colour of the ultimate leaflet segments, the inflorescence structure (peduncle length, number, and length of rays in the primary umbel), the fruit morphology (fruit size, presence or absence of wings), and the fruit anatomy (symmetry of the mericarps, presence or absence of additional rib vittae, size of commissural vittae). Species relationships are assessed in the form of a cladistic analysis of 26 morphological characters, resulting in a well-resolved phylogenetic hypothesis. A comprehensive key to the species, their correct nomenclature, and typification, together with descriptions and known geographical distribution for all the species are presented and illustrated.

Rove beetles of the genus Piestus Gravenhorst, 1806 are commonly captured under the bark of or inside decaying logs from Neotropical forests. Piestus belongs to the subfamily Piestinae, historically an ill-defined dumping-ground for Staphylinidae defined by plesiomorphic characters, but which has gradually been restricted in concept and currently includes only six additional extant genera worldwide. Piestinae in this restricted sense has been considered a probably monophyletic subfamily, but its status and phylogenetic position, as a possible sister-group of Osoriinae within the recently proposed Oxyteline group of staphylinid subfamilies, are uncertain and need confirmation. The main aim of the present study was to provide a morphological cladistic analysis and complete taxonomic revision of Piestus, which, as the type and most speciose genus of Piestinae, is critical for future phylogenetic studies involving the subfamily. In our study, the monophyly of Piestus is established and phylogenetic relationships among its species are proposed based on 70 adult morphological characters. Piestus is supported by 11 synapomorphies and high branch support. All species of Piestus are revised and the genus is redefined. The genus contains 43 species, including 13 species described here for the first time. The previously proposed subgenera Antropiestus Bernhauer, 1917, Eccoptopiestus Scheerpeltz, 1952, Elytropiestus Scheerpeltz, 1952, Lissopiestus Scheerpeltz, 1952, Piestus s. str., Trachypiestus Scheerpeltz, 1952 and Zirophorus Dalman, 1821 have not been confirmed, as they were found to be poly- or paraphyletic, or are here removed from Piestus, and therefore subgenera are not used. The main taxonomic changes are as follows. Lissopiestus, syn. nov. is proposed as new synonym of Eleusis Laporte, 1835 and its species, E. interrupta (Erichson, 1840), comb. rest., is transferred again to that genus. Antropiestus, syn. nov. and Eccoptopiestus, syn. nov. are proposed as new synonyms of Hypotelus Erichson, 1839 and their species, H. laevis (Solsky, 1872), comb. nov. and H. andinus (Bernhauer, 1917), comb. nov., are transferred to Hypotelus. Fourteen new synonymies are proposed (valid species listed first): P. lacordairei Laporte, 1835 = Z. furcatus Sharp, 1887, syn. nov.; P. capricornis Laporte, 1835 = P. frontalis Sharp, 1876, syn. nov.; P. pennicornis Fauvel, 1864 = P. plagiatus Fauvel, 1864, syn. nov.; P. rectus Sharp, 1876, syn. nov.; P. pygialis Fauvel, 1902, syn. nov.; P. surinamensis Bernhauer, 1928, syn. nov.; P. minutus Erichson, 1840 = P. nigrator Fauvel, 1902, syn. nov.; P. sulcatus Gravenhorst, 1806 = P. sanctaecatharinae Bernhauer, 1906, syn. nov.; P. condei Wendeler, 1955, syn. nov.; P. gounellei Fauvel, 1902 = P. wasmanni Fauvel, 1902, syn. nov.; P. mexicanus Laporte, 1835 = P. alternans Sharp, 1887, syn. nov.; P. aper Sharp, 1876 = P. schadei Scheerpeltz, 1952, syn. nov.; P. angularis Fauvel, 1864 = P. crassicornis Sharp, 1887, syn. nov.; H. andinus (Bernhauer, 1917) = P. strigipennis Bernhauer, 1921, syn. nov. One species is revalidated: P. fronticornis (Dalman, 1821), stat. rev., and one synonym is restored: P. penicillatus (Dalman, 1821) = P. erythropus Erichson, 1840, syn. rest. Neotypes are designated for P. lacordairei Laporte, 1835 and Oxytelus bicornis Olivier, 1811, and lectotypes are designated for P. puncticollis Fauvel, 1902, P. capricornis variety muticus Fauvel, 1902, P. zischkai Scheerpeltz, 1951, P. pennicornis Fauvel, 1864, P. plagiatus Fauvel, 1864, P. pygmaeus Laporte, 1835, P. niger Fauvel 1864, P. minutus Erichson, 1840, P. nigratror Fauvel, 1902, P. sulcatus Gravenhorst, 1806, P. sanctaecatharinae Bernhauer, 1906, P. sulcipennis Scheerpeltz, 1952, P. aper Sharp, 1876, P. schadei Scheerpeltz, 1952 and P. andinus Bernhauer, 1917.

Dicepolia Snellen (syn. Endolophia Hampson) is revised to include thirteen species distributed in the Neotropics and Madagascar. The genus is diagnosed and differentiated from similar Neotropical Pyraloidea. The two previously described species, the type species D. roseobrunnea (Warren) (tropical South America) and D. rufitinctalis (Hampson) (Central and South America), are redescribed. Seven new species are described: D. aerealis sp. nov., D. amazonalis sp. nov., D. artoides sp. nov., D. bicolor sp. nov., D. cuiabalis sp. nov., D. vaga sp. nov. and D. venezolalis sp. nov. Four Malagasy species are transferred to Dicepolia: D. marginescriptalis (Kenrick) comb. nov., D. marionalis (Viette) comb. nov., D. munroealis (Viette) comb. nov., and D. rufeolalis (Mabille) comb. nov. Two continental African species are transferred from Endolophia to other odontiine genera: Emprepes sudanalis (Zerny) comb. nov. and Tegostoma aequifasciale (Zerny) comb. nov. D. roseobrunnea is identified as the “rosada da oiticica,” a historical seed-boring pest of Licania in northeastern Brazil; published observations of larval morphology and behavior are summarized. Habitus and genitalia of all species are illustrated, and a key to the Neotropical species is given.

Preliminary Phylogenetic Analysis

AbstractThe subgenus M. (Scaphigenia) Lacordaire includes six species distributed in arid regions of South America. A systematic revision of this subgenus is presented, including re-descriptions and an update of distribution data of the six species. A preliminary cladistic analysis is performed to test the relationships among the species of the subgenus and if the morphological characters used are suitable. A key is presented to separate the seven subgenera of Megalostomis Chevrolat as well as a key for the species of the subgenus M. (Scaphigenia). Male aedeagus internal sac of the nine studied taxa are described and illustrated. This constitutes the first internal sac descriptions for members of this subtribe and could help clarify the homology of such structures within Cryptocephalinae. M. (S) consimilis Achard is reassigned to the species status on the base of genitalic characters. The cladistic analysis was done using forty-one characters from adult external morphology and male and female genitalia. Two species of two different subgenera of Megalostomis: M. (Megalostomis), and M. (Heterostomis) Lacordaire, and one representative of the genus Themesia Lacordaire were selected as out groups. Results were obtained by implicit enumeration using parsimony software. Three equally parsimonious trees were obtained of 45 steps, Ri=0.952, and Ci= 0.941. Support of each group was evaluated by Jacknifing, Bootstrap and Bremer values. Relationships between species are discussed.

Biogeographic Regions

Gasteruptiinae is the largest Gasteruptiidae subfamily, with circa 400 species that have been grouped into the worldwide Gasteruption Latreille. Based on a cladistic analysis with 43 morphological characters, 40 ingroup taxa representing all biogeographic regions, and seven outgroups (four Hyptiogastrinae, two Aulacidae and one Evaniidae), I confirm the monophyly of Gasteruptiinae and Gasteruption and recognize three exclusively Neotropical small genera: Plutofoenus Kieffer (revalidated) (southern South America), Spinolafoenus Macedo n. gen. (Chile) and Trilobitofoenus Macedo n. gen. (Central and South America). Gasteruption, supported by four synapomorphies, remains the most speciose genus in the subfamily. The four Gasteruptiinae genera are keyed and described. Seven species are keyed and described or redescribed: Plutofoenus chaeturus (Schletterer) n. comb., P. edwardsi Turner, P. paraguayensis (Schrottky), Spinolafoenus ruficornis (Spinola) n. comb., Trilobitofoenus alvarengai Macedo n. sp., T. plaumanni Macedo n. sp. and T. sericeus (Cameron) n. comb. (lectotype designated).

Informal Group

The Chusquea ramosissima informal group, including four named species, is classified within Chusquea subg. Chusquea based on morphological characters, but has not been rigorously studied in its entirety. The putative synapomorphies distinguishing the C. ramosissima informal group from the remainder of Chusquea subg. Chusquea are the presence of a pseudopetiolate culm leaf blade that remains green and synflorescences borne on a mix of longer leafy and shorter non-leafy subsidiary branches per node, features unknown in the rest of the subgenus or the genus as a whole. In addition, the species of the C. ramosissima informal group share a bud complement with a set of 1–4 laterally compressed, + falcate subsidiary buds on each side positioned facing each other, a central bud with parallel sides and a broadly triangular apex, and thin-textured spikelets. Because of this unique combination of characters, including two that are unique within Chusquea, and molecular support, we here formally describe Chusquea sect. Tenellae within Chusquea subg. Chusquea to accommodate this group. Five species, distributed in Argentina, Brazil, Bolivia, Paraguay and Uruguay, are included in the newly recognized Chusquea sect. Tenellae: C. fasciculata, C. ramosissima, C. tenella, C. tenuiglumis, and the newly described C. ovatifolia. This revision includes a comparison of sect. Tenellae with the five previously recognized sections of subg. Chusquea, detailed descriptions for the five species of sect. Tenellae, line illustrations or images for all species, maps of their distributions, and morphological keys for their identification. The names Chusquea fasciculata, C. tenuiglumis, C. tenuiglumis var. laxiuscula and C. tenuiglumis var. subcylindrica are lectotypified.

Morphological Distinction

Within the Dinaric genus Troglocaris cave shrimps from the subgenus Troglocaris s. str. (Dormitzer, 1853) (Crustacea:Decapoda: Atyidae), have the widest distribution area. The recent molecular analyses have revealed significant, crypticdiversity in the subgenus. The aim of the subsequent detailed morphometric analyses was the provision of the appropriatediagnosable characters for the discovered lineages, i.e. taking care of their taxonomical visibility. We herein designate aneotype and provide a detailed description for the polytipic type species of the genus T. (T.) anophthalmus (Kollar, 1848), toenable its morphological distinction from the erroneously described T. (T.) planinensis Birštejn, 1948. Considering acombination of morphological, geographical and molecular data, we describe four new subspecies: T. (T.) a. ocellata ssp. nov.,T. (T.) a. periadriatica ssp. nov., T. (T.) a. legovici ssp. nov. and T. (T.) a. sontica ssp. nov., apart from the extant T. (T.) a.intermedia Babić, 1922. Due to a considerable morphological variability and no easily observable diagnostic morphological characters, the GenBank accession numbers for the COI gene are added in all mentioned taxa.
