New species of Nanomis Lugo-Ortiz and McCafferty, 1999 (Ephemeroptera: Baetidae) from Venezuela

As the first taxonomic and faunistic report of Nanomis Lugo-Ortiz and McCafferty, 1999 for Venezuela, we describe a new species, N. rasmusseni sp. n., based on material from Andean streams. Comparisons of the nymphal and imaginal stages of N. rasmusseni with those of N. galera Lugo-Ortiz and McCafferty, 1999 – the only species currently known for this genus – are done in detail. Further, additional morphological characters are discussed to delineate the genus from the other baetid genera. Likewise, ecological data and distribution of N. rasmusseni in the Andean highlands of Venezuela are provided, which improves knowledge of the richness and distribution of the genus in South America.

Taxonomy of the Neotropical Genus Americabaetis,New Status (Insecta: Ephemeroptera: Baetidae)

Americabaetis (Insecta: Ephemeroptera: Baetidae), previously considered synonymous with Acerpenna, is reinstated and given generic rank. The genus differs from Acerpenna in lacking hindwings, gills on abdominal segment 1, and a conical process between the male genital forceps, and in possessing apically rounded gills on abdominal segment 7. The genus has a general Neotropical distribution with a northern limit in east-central Mexico. Five new species of Americabaetis are described from South America: A. alphus, new species, from Argentina, Bolivia, Brazil, Chile, and Paraguay; A. labiosus, new species, from Brazil, Paraguay, and Uruguay; A. longetron, new species, from Brazil, Paraguay, and Uruguay; A. maxifolium, new species, from Paraguay; and A. titthion, new species, from Brazil. Americabaetis boriquensis, new combination; A. intermedius, new combination; A. naranjoi, new combination; A. pleturus, new combination; and A. robacki, new combination, are reviewed.     

Mayflies (Ephemeroptera) from Reserva Ecológica Michelin,Bahia, Brazil

New records and distributional notes are provided for Reserva Ecológica Michelin, an Atlantic Forest fragment near the southern coast of Bahia State, Brazil. Two families, four genera and five species are recorded for the first time in Bahia State. Additionally, one family, two genera and three species are also recorded for the first time in the Northeast Region of Brazil, resulting in nine families, 48 genera and 96 species recorded to this region. Amongst the recorded species, Hermanella mazama (Nascimento, Mariano, and Salles, 2012) has been classified as an endangered species on the official Brazilian red list.     

Vetuformosa buckleyi n. gen., n. sp. (Ephemeroptera: Baetidae; Vetuformosinae n. subfam.), a new subfamily of mayflies in Early Cretaceous Burmese amber

A new subfamily, genus and species of mayflies, Vetuformosa buckleyi n. gen., n. sp. (Ephemeroptera: Baetidae; Vetuformosinae n. subfam.), are described as the first representative of the family Baetidae from Early Cretaceous Burmese amber. The female fossil is characterised by unusually long antennae, two pairs of gonostyli representing a primitive appendiculate ovipositor, sensory patches on sternites 8, 9 and 10, protuberances on the egg chorion and the absence of a costal projection on the hind wing. This is the first documentation of such long antennae and a primary ovipositor in the Ephemeroptera.     

Four new Brazilian species of Lonchocarpus (Leguminosae, Papilionoideae, Millettieae)

Lonchocarpus castaneifolius, L. grazielae, L. longiunguiculatus, and L. montanus from Brazil are described and illustrated based on field and herbarium studies. The first species belongs to Lonchocarpus sect. Punctati and is restricted to northeastern Brazil (Bahia state). The other three are included in sect. Laxiflori. Lonchocarpus grazielae is restricted to the southern coastal region (Santa Catarina state), L. montanus is found in northeastern Brazil (Bahia and Piauí states), the west-central region (Goiás and Tocantins states) and the southeast (Minas Gerais state), and L. longiunguiculatus occurs in northeastern (Bahia state) and southeastern (Minas Gerais state) Brazil.     

Three new species of Dendropanax (Araliaceae) from Bahia, Brazil

Three new species of BrazilianDendropanax from the rain forests of Bahia state are described and illustrated.Dendropanax amorimii, endemic to the rain forests near Boa Nova, in southern Bahia, is characterized by compound umbellate inflorescences with elongated primary branches each having a proximal whorl of bracts, and by leaves with well-developed tertiary venation.Dendropanax bahiensis, endemic to the Atlantic rain forests of southern Bahia, is distinguished by its large and membranous leaves with reddish schizogenous glands on the abaxial surface and by the reduced and branched inflorescences with short-pedicellate flowers and large fruits.Dendropanax geniculatus, an endemic species from the “matas de grotão” of Serra da Chapadinha, Chapada Diamantina, is characterized by simple and usually geniculate inflorescences bearing long-pedicellate flowers and fruits.     

A taxonomic review of Eucalantica Busck (Lepidoptera, Yponomeutidae) with descriptions of six new species

The New World genus Eucalantica Busck, 1904 is reviewed. It comprises seven species, six of which are described as new: Eucalantica costaricae Sohn & Nishida, sp. n., Eucalantica ehecatlella Sohn & Nishida, sp. n., Eucalantica icarusella Sohn & Nishida, sp. n., Eucalantica powelli Sohn, sp. n., and Eucalantica pumila Sohn, sp. n., all five from Costa Rica; Eucalantica vaquero Sohn, sp. n. from southern USA and Mexico. The type species, Eucalantica polita (Walsingham, 1881), is redescribed and a lectotype and two paralectotypes are designated. Illustrations and keys based on the forewing patterns and the genitalia of each sex are provided. Our review suggests that there remains an undiscovered high diversity of Eucalantica in the tropical highlands of Central America.     

The Larva of Rhoenanthus distafurcus Bae et McCafferty (Ephemeroptera: Potamanthidae) with Notes on Distribution and Biology

The larva of Rhoenanthus (Rhoenanthus) distafurcus Bae et McCafferty, 1991 is described for the first time from specimens taken in southern Vietnam. Critical characters distinguishing it from other species of the family Potamanthidae are keyed and figured. Distribution of R. distafurcus is summarized, including a list of 14 new occurrence records from Vietnam. Some aspects of its biology (habitat, larval habits, emergence and life cycle) are discussed.     

Two New Species of <Emphasis Type="Italic">Xenotarsonemus</Emphasis> (Acari: Tarsonemidae) from the Atlantic Forest,Brazil

Two new species, Xenotarsonemus quiriri n. sp. and Xenotarsonemus scorpius n. sp., are described and illustrated in this paper based on specimens collected on Myrtaceae plants in Atlantic Forest areas of the states of Bahia and Santa Catarina, Brazil. A key to identification of Xenotarsonemus species reported from Brazil is provided.     

Simulium (Psilopelmia) virescens, a new black-fly species (Diptera: Simuliidae) from the southwestern region of the state of Bahia, Brazil

The last-instar larva, pupa, male and female of Simulium virescens sp. nov. are described and illustrated. This species has a peculiar larva, which has an elongated head capsule and light-green colour. The first thoracic segment has tubercle on its dorsal region and the third thoracic segment has one pair of tubercles; the first to the fourth abdominal segments have one pair of tubercles on each segment. Until now this new species had only been collected at the type locality, which is on the middle stretch of the Correntina River in the southwestern portion of the state of Bahia, Brazil. Females were voraciously biting humans during the field work. This new species represents the second species of Simulium (Psilopelmia) in Brazil and the first registered outside of the Brazilian Amazon Region.     

A Potentially Endangered New Species of <Emphasis Type="Italic">Euptychia</Emphasis> Hübner, 1818 (Lepidoptera: Nymphalidae: Satyrinae) from the Atlantic Coastal Forest of Brazil

A new satyrine species in the subtribe Euptychiina, Euptychia atlantica Nakahara & Freitas sp. nov., is described from the Atlantic coastal forest of Brazil. Based on the existing museum specimens, E. atlantica sp. nov. is known from the coastal montane forests of Rio de Janeiro to south Bahia, a unique biogeographical region which is undergoing rapid degradation. Illustrations of adults and their genitalia, as well as a distribution map, are provided herein, in addition to a discussion of the relationships and conservation status of the new species.     

Monorchiid trematodes of the painted sweetlips,Diagramma labiosum (Perciformes: Haemulidae), from the southern Great Barrier Reef,including a new genus and three new species

Five monorchiid species are reported from Diagramma labiosum Macleay (Perciformes: Haemulidae) collected from Heron Island on the southern Great Barrier Reef (GBR): two described species, Helicometroides longicollis Yamaguti, 1934 and Diplomonorchis kureh Machida, 2005 and three new species, including one new genus, Asymmetrostoma heronensis n. g., n. sp., Lasiotocus arrhichostoma n. sp. and Proctotrema addisoni n. sp. Helicometroides longicollis and D. kureh were previously reported from the closely related species Diagramma pictum (Thunberg) from Japan. Two further monorchiid species known from D. pictum, Genolopa plectorhynchi (Yamaguti, 1934) and Paraproctotrema fusiforme Yamaguti, 1934, appear to be absent from the southern Great Barrier Reef. Previous reports of two other monorchiids from D. labiosum from the GBR, Paramonorcheides pseudocaranxi Dove & Cribb, 1998 and Helicometroides vitellosus (Durio & Manter, 1968), are shown to have been made in error. The high richness of monorchiids and other trematode families in D. labiosum is consistent with that seen in other haemulids elsewhere.     

Notobaetis: A New Genus of Baetidae (Ephemeroptera) from South America

A new genus and species, Notobaetis penai, n. gen., n. sp., of Baetidae (Ephemeroptera), is described based upon reared specimens collected from the Cordoba Province of Argentina. This new genus appears to be phenetically intermediate between Baetis Leach and Centroptilum Eaton while possessing a unique combination of characters and one autapomorphic character.     

New taxa of Leguminosae-Caesalpinioideae from Bahia,Brazil

Brodriguesia santosii, gen. & sp. nov., from the coastal rain forest of Bahia, is described, illustrated and compared with nearly related genera of the tribe Detarieae. In addition, three new species, Arapatiella emarginata (the second species of the genus), Swartzia oblata, S. pinheiroana and one new variety, Goniorrhachis marginata var. bahiana, are presented.     

The Subfamily Cytheropterinae Hanai, 1957 (Subphylum Crustacea,Class Ostracoda) from the Southern Brazilian Continental Shelf

The study of the subfamily Cytheropterinae from the southern Brazilian continental shelf reveals the presence of four genera and nine species, including two newly described (Cytheropteron sudatlanticum sp. nov., Loxoreticulatum pulchrum sp. nov.) and two left in open nomenclature (Cytheropteron sp. and Kangarina sp.). All of these species are restricted to the southern part of the Southwest Atlantic Ocean and do not extend beyond the coast of Rio de Janeiro, Brazil. Three of these species (Oculocytheropteron micropunctatum, O. reticulatum, O. macropunctatum) extend beyond the southern limit of the Brazilian Province (36°S), while the others occur inside the limits of the Brazilian Province (36°S–22/21°S). The genus Loxoreticulatum, a well-known ostracod taxon from the Antarctic Peninsula, southern Argentina and Falkland (= Malvinas) Islands, is herein reported for the first time from offshore Brazil.     

Male and female association in Trichomyia Haliday in Curtis, 1839 using a molecular approach (Diptera,Psychodidae, Trichomyiinae), and description of new species from Brazil

A new species of Trichomyia from the state of Bahia, Brazil, is described and illustrated, and male and female are associated using DNA barcoding. Additionally, fragments of the COI of two other species, Trichomyia cerdosa Araújo & Bravo, 2016 and Trichomyia ituberensis Araújo & Bravo, 2016, and the females of two unidentified species, are sequenced.     

A new species of Scolopocryptops Newport: a troglobitic scolopocryptopine centipede from a remarkable siliciclastic area of eastern Brazil (Scolopendromorpha,Scolopocryptopidae, Scolopocryptopinae)

We describe Scolopocryptops troglocaudatus sp. n., a new troglobitic scolopocryptopine centipede species. The species was found in a remarkable siliciclastic karst area of Eastern Brazil, in three caves of the Chapada da Diamantina, in the state of Bahia. Scolopocryptops troglocaudatus sp. n. is close to Scolopocryptops miersii Newport, 1845 and Scolopocryptops ferrugineus macrodon (Kraepelin, 1903) but differs from them by troglomorphic features, such as depigmentation, long appendages and a thin cuticle. This new species is the second troglobitic scolopocryptopine described and is the first discovered in Brazil.     

The genus Alterosa Blahnik, 2005 (Trichoptera,Philopotamidae, Philopotaminae) in northeastern Brazil,including the description of three new species and an identification key for the genus

Alterosa Blahnik, 2005 contains 35 described species distributed in southern and southeastern Brazil. Three new species of Alterosa from northeastern Brazil are described and illustrated, Alterosa amadoi sp. n., Alterosa castroalvesi sp. n. and Alterosa caymmii sp. n., the first records of the genus from northeastern Brazil. An identification key for all known species of the genus is also presented.     

Three new species of Galipea (Rutaceae, Galipeinae) from Brazil

Three new species of Galipea (Rutaceae, Galipeinae) are described and illustrated. Galipea carinata Pirani sp. nov. is known from the pluvial tropical forest in southern Espírito Santo State, eastern Brazil, and its main diagnostic features are the urceolate and conspicuously keeled calyx, the relatively short (14–16 mm) corolla tube, the long pedunculate, divaricate and loosely branched inflorescence, with few flowers crowded on tip of side branchlets, and the chartaceous leaflets, with lateral veins very prominent on both sides of the blade. Galipea revoluta Pirani sp. nov. is probably endemic to the coastal hygrophyllous Atlantic Forest in southern Bahia, eastern Brazil, and is very distinct by its mostly unifoliolate leaves, with a leathery, shiny lamina that is thickened and usually revolute at margin, by its calyx with large glands only at the base, and median nerve on each sepal. Galipea congestiflora Pirani sp. nov. is from forests on terra firme (non-inundated vegetation) of eastern Amazonia, most of them from the State of Pará, some others from eastern Maranhão and north of Tocantins. It is characterized mainly by 3-foliolate, chartaceous and dull leaves; a dense, corymbiform thyrsoid (partial inflorescences very short, crowded on top of the peduncle), which is smaller than the leaves; relatively large capsules (the largest in the genus) with an acute rim at the tip of each valve, and by the marmorate surface of the seeds. A brief discussion on the relationships of the new taxa to other species of Galipea is provided.  © 2004 The Linnean Society of London, Botanical Journal of the Linnean Society , 2004, 144, 365–373.
