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.

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.

The Zethus mexicanus group sensu Bohart & Stange (1965) consists of four species in the subgenus Zethusculus: Zethus brasiliensis de Saussure, 1852, Z. mexicanus (Linnaeus, 1758) (both subdivided into three subspecies each), Z. magnus de Saussure, 1852 and Z. waldoi Zavattari, 1912. Color patterns and distribution have been used to differentiate the subspecies until now. However, these patterns may vary among individuals, and the distribution of specimens examined in this study showed overlap between subspecies. The analysis of external morphology did not show significant differences, making the subspecific division unnecessary. Thus, the following synonyms are proposed: Zethus brasiliensis fuscatus Boharth & Stange, 1965 n. syn. and Z. brasiliensis panamensis Boharth & Stange, 1965 n. syn. are junior synonyms of Z. brasiliensis brasiliensis; and Z. mexicanus erythrogena Boharth & Stange, 1965 n. syn. and Z. mexicanus lugubris Perty, 1833 n. syn. are junior synonyms of Zethus mexicanus mexicanus. Furthermore, the following status changed are proposed: Z. brasiliensis brasiliensis de Saussure, 1852 stat. rev. to Z. brasiliensis; and Z. mexicanus mexicanus (Linnaeus, 1758) stat. rev. to Z. mexicanus. In addition, a cladistic analysis, using terminals with representatives of the three subgenera of Zethus and one species of Ctenochilus, recovered the monophyly of the Zethus mexicanus group, as well as the subgenus Zethusculus, but rendered the arietis group paraphyletic. An identification key and redescriptions are given for the species in the group of Zethus mexicanus sensu Bohart & Stange (1965).

General Aspects

Palpada Macquart, 1834 is a large genus of tropical Eristaliini flies with distribution restricted to the New World (Diptera : Syrphidae : Eristalinae). Most species were initially placed within Eristalis Latreille, 1804. In 1972, most Neotropical species were transferred to Palpada when F.C. Thompson divided Eristalis sensu lato into three genera: Eristalis, Eoseristalis Kanervo, 1938 and Palpada. The latter genus was divided by Thompson (1981) into three groups of species: scutellaris, agrorum and vinetorum. In the present study, the species of the scutellaris group are revised and the phylogenetic relationships among its species are reconstructed based on adult morphology. The cladistic analysis of the 24 terminal species and 48 characters of external morphology and male and female genitalia, produced one cladogram under equal weights. The monophyly of the scutellaris group was corroborated. Twelve species are recognised within the group, of which one is described as new: Palpada cordiformis Morales, sp. nov., P. claudia (Curran), P. conica (Fabricius), P. doris (Curran), P. erratica (Curran), P. fuliginosa (Hull), P. megafemur Thompson, P. melanaspis (Wiedemann), P. precipua (Williston), P. rufoscutellata (Sack), P. scutellaris (Fabricius) and P. vera (Hull). Two new synonymies are proposed: P. dorothea (Hull, 1942) = P. melanaspis (Wiedemann, 1830); and P. glabella (Hull, 1942) = P. fuliginosa (Hull, 1935). The lectotype is designated for Eristalis melanaspis. An identification key, a catalogue, distribution maps, illustrations of general aspects, illustrations of male and female genitalia and scanning electron micrographs are provided.

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.

AbstractHersiliidae Thorell is a family of conspicuously long-legged spiders, characterized by extremely elongate posterior lateral spinnerets. To date, it includes 148 species distributed within seven genera, of which Tama Simon is the only one recorded in the Neotropical Region. Of the 23 known Tama species, 18 are exclusively Neotropical. In order to enhance the scientific knowledge on the family and its members this study presents a cladistic analysis and a taxonomic revision of the Neotropical and Nearctic hersilids. The cladistic analysis places the Neotropical and Neartic species in two separate clades, none of which are closely related to the genus Tama. Based on this result, Tama mexicana (O.P.-Cambridge) and T. forcipata (F.O.P.-Cambridge) are transferred to Neotama and three new genera are proposed to include the remaining species: Ypypuera n. gen. to include T. crucifera Vellard and T. vittata (Simon); Iviraiva n. gen. to include T. pachyura Mello-Leitão and T. argentina Mello-Leitão; and Yabisi n. gen to include T. habanensis Franganillo. Based on the taxonomic revision, eight synonymies are proposed: Tama crulsi Mello-Leitão, Tama micrura Mello-Leitão and T. occidentalis Schenkel with Ypypuera crucifera (Vellard); T. brasiliensis Piza and T. karinae Carcavallo with I. pachyura (Mello-Leitão); T. catamarcaensis Carcavallo and T. longipes Carcavallo with I. argentina (Mello-Leitão); and T. guianensis Mello-Leitão with Neotama mexicana (O.P.-Cambridge); three names are placed as nomina dubia: Tama americana (Simon), T. albigastra Mello-Leitão and T. sasaimae Mello-Leitão and four new species are described: Neotama cunhabebe, from São Paulo, Brazil, Neotama obatala, from Bahia, Brazil, Ypypuera esquisita, from Quevedo, Ecuador, and Yabisi guaba, from Pedernales, Dominican Republic. The family Hersiliidae, the genus Neotama and all three new genera, as well as all Neotropical and Nearctic species are redescribed and diagnosed and a identification key is presented.
