The new genus Kempfidris gen. nov. is described based on the workers of a single species, K. inusualis comb. nov., from Brazil, Ecuador, and Venezuela. Kempfidris inusualis comb. nov. was originally described by Fernández (2007) and provisionally placed in Monomorium awaiting a better understanding of the internal relationships in Myrmicinae. Kempfidris gen. nov. has a series of distinctive morphological characters including the mandibular configuration, vestibulate propodeal spiracle, propodeal carinae, and cylindrical micro-pegs on the posteromedian portion of abdominal tergum VI and anteromedian portion of abdominal tergum VII. This last trait appears to be autapomorphic for the genus.

A new monotypic genus is herein described for the Western Cuban endemic whipscorpion Mastigoproctus pelegrini Armas, 2000. Its morphology is strikingly different from all other species of Mastigoproctus Pocock, 1894, but its generic placement remained unchallenged so far. Sheylayongium gen. n. is diagnosed from all other Mastigoproctinae Speijer, 1933 by a combination of several morphological characters of both sexes, e.g., high reduction of pedipalp armature and sexual dimorphism, carapace carination, unusual modification of sternite V, and female spermathecal structure. Its single species is thoroughly illustrated with high-resolution, full-color photographs, its geographical distribution is revised and updated, and new data are given on its natural history.

Morphological And Molecular Data

Abstract The freshwater fish genus Astyanax is one of the most diverse among the Characidae. The genus is defined by a combination of character states that are widely distributed in Characidae. In addition, the genus has the broadest geographical distribution in the family, being found in a great variety of environments of the Neotropical region. Although phylogenetic relationships were treated only partially, many authors agree that the genus is not monophyletic. In this contribution, we study the phylogenetic relationships of Astyanax in the context of the family Characidae, by combining morphological and molecular data. A total of 520 morphological characters, nine molecular markers and 608 taxa are analysed, of which 98 belong to Astyanax. According to our results, Astyanax is not monophyletic. We recovered species attributed to Astyanax in different subfamilies: Gymnocharacinae (including the type species), Stevardiinae and Tetragonopterinae. Among the species recovered in Gymnocharacinae, most (including the type species, the resurrected Psalidodon, and the new genus Andromakhe gen. nov.) were recovered in Gymnocharacini, while the remaining ones were recovered in Probolodini (transferred to Deuterodon or the new genus Makunaima gen. nov.).

Devilleferus brunkei Jenkins Shaw & Solodovnikov, gen. et sp. nov., a distinctive new genus and species of Staphylinini rove beetle with an unusual set of morphological characters is described from the tropical Andes (Ecuador and possibly Colombia and Bolivia) in South America. To resolve systematic placement of the new genus within Staphylinini we assembled a dataset of 68 morphological characters scored for 34 taxa representing a broad sample of the respective rove beetle tribe, and performed Bayesian inference and maximum parsimony phylogenetic analyses. Both analytical methods unambiguously placed Devilleferus as sister to the subtribe Amblyopinina, and overall they corroborated recently established subtribal systematics for Staphylinini inferred mainly from molecular markers. Based on the shared synapomorphies, Devilleferus is assigned to the subtribe Amblyopinina. The internal relationships within Amblyopinina remain to be clarified in a broader study of that very poorly explored austral lineage.

A new Australian genus of Therevidae, Acraspisoides gen. nov., comprising a single species (A. helviarta sp. nov.) is described and illustrated. This new genus is placed within the subfamily Agapophytinae based on the presence of velutum patches on the fore and hind femora. Acraspisoides is easily separated from other agapophytine genera by the combination of characters: large ventral lobe on aedeagus, multiple rows of postocular setae in both sexes, antennae positioned low on frons, and wing cell m 3 closed. Cladistic analyses using all genera of Agapophytinae (including Acraspisoides) based on adult morphological characters and sequence data of the protein-encoding gene, elongation factor-1 (EF-1a ), were performed to determine the phylogenetic placement of Acraspisoides gen. nov. in the subfamily. Analysis of the combined morphological and molecular matrices produced two most parsimonious trees, placing Acraspisoides gen. nov. as the most basal genus of Agapophytinae.

A new genus, Cryptassiminea, is introduced for the taxon previously known as Assiminea buccinoides (Quoy & Gaimard). These small gastropods are abundant in mangrove and salt marsh habitats in south-eastern and subtropical eastern Australia. Seven species (five new) are recognised using morphological characters in the complex previously treated as a single species. Five taxa have rather narrow ranges while the other two are widespread and often sympatric. Two groups of species are recognised. One contains Cryptassiminea buccinoides, widespread in south-east and east Australia, and two closely related allopatric taxa from South Australia and south-eastern Tasmania (C. adelaidensis, sp. nov. and C. kershawi, sp. nov.). A second group of species is typified by Cryptassiminea tasmanica (Tenison-Woods), also widespread in east and south-east Australia and often sympatric with C. buccinoides. Allied to C. tasmanica, are two closely related taxa from western Victoria: C. glenelgensis, sp. nov. from the Glenelg River estuary and C. surryensis, sp. nov. from the Surry River estuary and Western Port, in the vicinity of Geelong. A distinctive species, Cryptassiminea insolata, sp. nov. from the east coast of Queensland, also has similarities with C. tasmanica. A cladistic analysis using morphological characters of the Cryptassiminea taxa and three other genera of Assimininae, with an omphalotropidine as the outgroup, resulted in a single tree. The new genus has rather poor support, possibly because many of its characters appear to be plesiomorphic within Assimineinae. Cryptassiminea is defined by a unique combination of characters but lacks any obvious synapomorphy. Two clades within Cryptassiminea are well supported, each containing the species-groups referred to above.

Konradus leehermani Chani-Posse & Ramírez-Salamanca, a new genus and species of the subtribe Philonthina (tribe Staphylinini) from the Tropical Andes of Ecuador, is described and illustrated. A dataset of 57 morphological characters scored for 23 taxa representing main clades of Philonthina and its putative sister groups was prepared and analysed by maximum parsimony and Bayesian inference. Both analytical methods unambiguously placed Konradus within the Neotropical (NT) lineage of Philonthina. Phylogenetic relationships of Konradus with other Neotropical representatives are proposed and discussed.

The coastal lowland rain forests of eastern Africa are well known for their high levels of plant endemism. A new genus of Annonaceae, Mwasumbia, is described from Tanzania, underscoring this high biodiversity and represented by a single species, Mwasumbia alba. The new genus presents several morphological characters suggesting a close relationship to two other African genera, Greenwayodendron and Polyceratocarpus. Maximum parsimony and Bayesian molecular phylogenetic analyses based on two plastid markers, rbcL and the trnL-trnF region, strongly support the close relationship of these three genera to one another as well as to two other African genera, Annickia and Piptostigma. Together these five genera form a moderately supported clade within the so-called short-branch clade of Annonaceae. A detailed morphological and palynological comparison between Mwasumbia and the four other genera shows that this new genus exhibits a combination of features unique within this group: intermediate tertiary leaf venation, exclusively bisexual flowers, slightly imbricate sepals, valvate petals, outer and inner petals equal in length, numerous stamens, four carpels, few and uniseriate ovules, few and sessile monocarps, and verrucate sulculate pollen grains. Phylogenetic analyses also suggest the genus Piptostigma, as currently circumscribed, to be paraphyletic. An IUCN conservation status of VU D2 is proposed, reflecting the narrow distribution of the single species.
