Dolichomitus Smith, 1877 is a genus of Darwin wasps characterised by their large bodies and long ovipositors, that includes more than 75 species worldwide, 20 of which occur in the Neotropical Region. Due to recent efforts, the number of species of this genus continues to increase in South America. A new iridescent species of Pimplinae, Dolichomitus meii sp. nov., is described and illustrated. It was discovered from the biological station of Yanayacu located in the north-eastern slopes of the tropical Andes. It may be separated from all other species of Dolichomitus Smith by the striking colour pattern and apically strongly decurved ovipositor.

A checklist of the oribatid mite species reported in Brazil is presented, including all published records up to 2015. A total of 576 described species in 206 genera and 83 families is presented. Information includes the names by which each species was reported in the Brazilian literature, its general known distribution and by Brazilian States, references, and remarks, when needed. As with most countries, there was a slow early accumulation of knowledge but in recent decades the pace of description has been relatively high. A graphical overview of the number of described oribatid mite species from Brazil in different decades is given. The proportion contributed by each of the major oribatid groups is generally similar to that of the overall world fauna, with a composition that reflects the South American fauna and all of the Neotropics in general. There is a relatively low percentage of primitive mites (Palaeosomata, Enarthronota) other than Lohmanniidae and Mesoplophoridae, which are quite diverse. The Brachypylina comprises about 68% of the oribatid mite fauna. In the checklist, 41% of the species are known only from Brazil, 37% from the Neotropical region, 13.5% have a wider distribution in the global tropical and subtropical regions, and 8.5% are considered cosmopolitan or semicosmopolitan species. The number of descriptions of new species since 2000 from Brazil (73 spp.) and South America (230) is high, but the oribatid mite fauna of these countries remains poorly known. Only continued studies can determine if the high number of species known only from Brazil is an indication of high endemism.

A New Species

A new species of Charinus Simon, 1892 is described from French Guyana, raising the number of species in the genus to48 (27 for the Neotropical region and 19 for South America). Charinus bromeliaea sp. n. is distinguished from the otherspecies in the genus by morphological characteristics and unique ecology. Adapted to live in Achmea bromeliads on gran-ite inselbergs, this species is an interesting addition to the wide range of habitats Charinus species are found in. This is also the first record of the genus from French Guyana and this record extends the geographic distribution of the genus.

Abstract—A synopsis of Dicliptera (Acanthaceae) for Brazil is presented. Six species are recognized: Dicliptera ciliaris, D. sexangularis, and D. squarrosa, widely distributed in South America; D. purpurascens, which ranges from the North Region of Brazil (in the state of Acre) to eastern Bolivia; D. gracilirama, a new species from the Atlantic Forest of northeastern Brazil; and D. granchaquenha, a new species recorded in dry and semideciduous forests in Bolivia and western Brazil, in the state of Mato Grosso do Sul. Furthermore, we propose new synonyms and designate lectotypes for eleven names. An identification key to the six accepted Dicliptera species in Brazil is provided.

Two new species of Bohayella Belokobylskij, 1987 from Costa Rica are described: Bohayella geraldinae Kang, sp. nov. and Bohayella hansoni Kang, sp. nov. These are new distribution records for the genus in the Neotropical region. In addition, a key to species of the genus Bohayella of Costa Rica is presented. The current work elevates the number of species included in Bohayella from nine to eleven.

Abstract Piresia, a small genus of herbaceous bamboos, has a geographical disjunction between the Caribbean and northern/western South America and the north-eastern Atlantic Forest in Brazil. Piresia leptophylla is reported from western Amazonia (WA) and the north-eastern Atlantic Forest (NAF), but its occurrence in western Amazonia is questionable. Using an integrative approach, we combined traditional morphological analysis, anatomy and niche modelling. The results revealed few macromorphological differences between WA and NAF specimens (only plant height, leaf length, lodicule dimensions, shape and position), contrasting with consistent differences in leaf anatomy (macrohairs and cruciform silica bodies in the costal zone of the adaxial/abaxial leaf surfaces, crenate silica bodies on the abaxial leaf surface, lack of panicoid hairs on the abaxial leaf surface, bicellular microhairs and lobed papillae over the abaxial leaf surface, and sparse but elongated fusoid cells in the mesophyll of WA specimens) and in niche patterns. The anatomical/micromorphological characters suggest environmental adaptations to the Amazonian and ‘restinga’ forests, respectively. We therefore propose the segregation of the WA populations into a new species, Piresia tenella sp. nov. We provide a formal description, photographs, a line illustration, a distribution map and discussion of the conservation status for the new species.

Telebasis rojinegra sp. nov. was recorded from ponds at La Selva Biological Station and three other sites in the Caribbean lowlands of Costa Rica. The new species appears closely related to T. boomsmae Garrison, 1994 recorded from Mexico, Belize and Costa Rica, T. collopistes Calvert, 1902 ranging from Mexico to Honduras, and T. garrisoni Bick & Bick, 1995 from South America, but differs in having straighter and more elongate paraprocts and a half black pattern on the rear of the head. The female mesostigmal plates are also distinct from the above species. Telebasis rojinegra was active on the water primarily during afternoon hours.

The Neotropical Laccophilinae genus Laccodytes Régimbart, 1895 is redefined and revised. We recognize ten species, six of which are described as new. We define two species groups: the Laccodytes apalodes-group (L. apalodes Guignot, 1955, L. rondonia sp.n.), and the L. phalacroides-group (L. americanus Peschet, 1919, L. obscuratus sp.n., L. bassignanii sp.n., L. neblinae sp.n., L. olibroides Régimbart, 1895, L. phalacroides Régimbart, 1895, L. takutuanus sp.n., L. androginus sp.n.). Laccophilus pumilio LeConte, 1878, assigned to Laccodytes by Young (1954), belongs to an undescribed genus. Laccodytes species are lotic and most of them inhabit the north-eastern part of South America, apparently with Venezuela and Guyana as centre of diversity. Descriptions, illustrations and SEM photos of habitus, genitals and other diagnostic features are provided for each species, together with habitat notes, when known. We provide a key for species identification.
