Dialium (Leguminosae, Dialiinae) is pantropical and comprises about 40 species. Presently, only one species occurs in the Neotropics, Dialium guianense, which is found from eastern Mexico to northeastern Minas Gerais, Brazil. The objective of this study was to carry out a thorough taxonomic revision of Dialium in the Neotropics, to determine if species diversity of the genus in this region is underestimated. The study analyzed 765 collections, from 18 herbaria throughout the world, which revealed three groups of specimens that clearly differ from each other and from D. guianense. Morphology and biogeography support their recognition as new species. Dialium hexaestaminatum occurs in northern Colombia and western Venezuela, and is characterized by generally having six stamens, while the other neotropical species have only two. Dialium congestum occurs in Ecuador and southern Colombia and is mainly characterized by the presence of congested inflorescences, unlike the lax inflorescences found in the other neotropical species.  Dialium rondoniense occurs in the state of Rondônia and the most southern part of the state of Amazonas, Brazil. It is characterized by the dense coverage of trichomes on the abaxial surface of the leaflets, as well as the petiolules, petioles, leaf rachis and branches, while the other neotropical species are generally glabrous or covered with sparse trichomes that are imperceptible to the bare eye. The results show that the diversity of Dialium in the Neotropics was underestimated and that the genus has four species in the region. An identification key, illustrations and descriptions of the species are provided.

Kielmeyera ferruginosa, a new species of Calophyllaceae from the Atlantic Forest of southern Bahia, is here described and illustrated. The species is critically endangered and can be easily distinguished from other Kielmeyera species by the rusty coloration of the trunk and branches, orange-colored latex, and the occurrence in flooded areas. It differs from the other species of the section Prolifera by the leaves with secondary veins relatively more distant from each other and prominent on the abaxial surface. Diagnostic characters and the state of conservation of the new species are discussed, and an identification key for K. ferruginosa and related species from series Rupestres and Neglectae is provided.

A taxonomic revision of the Australian Conopidae is presented. Nineteen genera in four subfamilies are recognised. The Stylogasterinae are represented by the cosmopolitan genus Stylogaster Macquart and the Myopinae by Myopa Fabricius and Thecophora Rondani. A monotypic genus, Notoconops gen. nov., is described and placed in a new subfamily, Notoconopinae. The remaining fifteen Australian genera are assigned to the Conopinae. Australoconops Camras, Chrysidiomyia Kröber, Conops Linnaeus, Delkeskampomyia Kröber, Heteroconops Kröber, Microconops Kröber, Neoconops Kröber, Pleurocerina Macquart, Physocephala Schiner, Smartiomyia Kröber and Stenoconops Kröber are redescribed. Four new conopine genera are described: Atrichoparia; Camrasiconops; Setosiconops; and Tanyconops, with the following resultant new combinations: Atrichoparia curticornis (Kröber) (from Heteroconops); Camrasiconops ater (Camras) and Ca. rufofemoris (Camras) (from Microconops); and Setosiconops robustus (Kröber) (from Neoconops). Callosiconops Kröber and Paraconops Kröber are regarded as junior synonyms of Chrysidiomyia and Pleurocerina respectively with the following resultant new combinations: Chrysidiomyia hirsuta (Kröber), Pleurocerina aristalis (Camras), P. longicornis (Kröber), P. nigrifacies (Kröber), P. similis (Kröber), P. turneri (Camras). A total of 100 species of Australian Conopidae are now recognised. No new species of Myopinae or Stylogasterinae are described. Representative species only of Atrichoparia, Camrasiconops, Heteroconops and Microconops are described. All species of the other 12 genera are described or redescribed. These include the following 45 new species,: Australoconops aglaos, A. aurantius, A. balteus, A. breviplatus, A. brunneus, A. camrasi, A. cantrelli, A. elegans, A. fulvitarsus, A. furvus, A. nebrias, A. neuter, A. pallorivittus, A. phaeomeros, A. ruficrus, A. vespoides; Chrysidiomyia rugifrons, C. setosa; Conops aureolus, C. badius, C. chvalai, C. sparsus; Heteroconops carnarvonensis; Neoconops brevistylus, N. glaber; Notoconops alexanderi, Pleurocerina aquila, P. brevis, P. chrysopyga, P. lamellata, P. lutea,P. luteiceps, P. occidua, P. saxatilis, P. scutellata, P. vespiformis; Setosiconops epixanthus, Se. similis, Smartiomyia arena, Sm. cerina, Sm. danielsi, Sm. macalpinei; Tanyconops longicaudus, T. luteus, T. ocellatus. Australoconops ocellatus (de Meijere) comb. nov. is resurrected from synonymy with A. aurosus (Newman). Conops demeijerei Kröber is considered a junior synonym of C. seminiger de Meijere. A lectotype and paralectotypes are designated for Microconops fasciatus Kröber. Anatomical features used in descriptions are discussed and illustrated. Special attention has been given to the ultrastructure of spicules on female genital structures. These spicules show differences between genera and species. The high degree of endemism of the Australian fauna is discussed in relation to the world fauna and some preliminary thoughts on phylogenetic relationships are presented. A catalogue of the Australian Conopidae is included as an Appendix.

Syntypes of Peliosanthes bakeri and four varieties (var. clarkei, var. minor, var. princeps and var. violacea) of P. violacea were reexamined to review their identities. As a result, it turned out that the syntypes of P. bakeri comprise two species, P. griffithii and P. subspicata sp. nov., and those of P. violacea include at least six species, P. griffithii, P. khasiana sp. nov., P. macrostegia, P. subspicata, P. teta, and P. violacea. The two new species, P. khasiana from NE India and P. subspicata from Bangladesh and NE India are described and illustrated. The other four species recognised are taxonomically revised as to their identity, circumscription and distribution. In this connection, lectotypes for five taxa are designated. An identification key for the six species recognised is also provided.

The Neotropical genus Marma Simon, 1902 is revised. With exception of the holotype of M. femella (Caporiacco, 1955), which was redescribed in previous work, all the other species of the genus were revised based on their types. The type species, M. baeri Simon, 1902, and M. nigritarsis (Simon, 1900) are redescribed based on newly collected specimens. The third and last species presently listed in the World Spider Catalog, M. femella, is confirmed as valid. Two species presently considered synonyms of M. nigritarsis are revalidated: M. rosea (Mello-Leitão, 1941) and M. argentina (Mello-Leitão, 1941). Two species are synonymized: Thysema dorae Mello-Leitão, 1944, syn. nov. with Ocnotelus argentinus Mello-Leitão, 1941 and Paralophostica centralis Soares & Camargo, 1948, syn. nov. with Agelista rosea Mello-Leitão, 1941. Pseudoamphidraus variegatus Caporiacco, 1947 and M. trifidocarinata Caporiacco, 1947 are confirmed as synonyms of M. nigritarsis. Six new species from northern/northeastern Brazil are described: M. abaira sp. nov. (♀), M. linae sp. nov. (♂♀), M. pipa sp. nov. (♂♀), M. sinuosa sp. nov. (♂♀), M. spelunca sp. nov. (♂♀) and M. wesolowskae sp. nov. (♂♀). Also, the male of M. argentina is described for the first time. We give new diagnostic illustrations and updated distribution records for all the species of the genus.

The Passiflora subgenus Astrophea has its greatest diversity in the Amazon Rainforest, which is the largest biodiversity reserve in the world. During a taxonomic revision of Brazilian Astrophea species, a new species was discovered from the municipality of São Gabriel da Cachoeira in the state of Amazonas. Morphological and palynological analysis, as well as comparisons with related species, confirmed that the specimen represents a new species to science belonging to the Passiflora subgenus Astrophea, section Pseudoastrophea. Passiflora lorenziana is the name given to the new Amazonian species, which is herein described, illustrated and compared to related species.

Three Neotropical species of Phthinia Winnertz have been described to date. The genus is known from Chile and southern Argentina. Four new species are herein described for the genus in the region, two from Brazil—Phthinia theresae, sp.n., from the State of Espírito Santo, and Phithinia urubici, sp.n., from the State of Santa Catarina—and two from Chile—Phthinia freemani, sp.n., and Phthinia parafurcata, sp.n. Comments are made about the relationships between the Neotropical species. Some notes are added about P. furcata Freeman, P. flagellata Freeman, and P. fasciata Freeman, from Chile and southern Argentina. Attention is called for the fact that Phthinia has two species in Brazil disjunct from the other temperate species of the genus in South America, differently from most similar cases, that have a single known representative in Brazil.
