The genus Oxyethira comprises over 200 species distributed worldwide. In Brazil, 23 species have been recorded, mostly from the North Region, but this number is still an underestimate. To date, six species have been recorded from the Northeast Region of Brazil (from Ceará, Piauí, and Pernambuco states). In this work, we describe and illustrate 11 new species from this region: Oxyethira calori sp. nov., O. diplospissa sp. nov., O. guariba sp. nov., O. iannuzzae sp. nov., O. maranhensis sp. nov., O. rafaeli sp. nov., O. gracilianoi sp. nov., O. retrosa sp. nov., O. septentrionalis sp. nov., O. singularis sp. nov., O. una sp. nov. Additionally, new distributional records for five other species are given. These results increase the number of Oxyethira species in Brazil from 23 to 35.

The genus Oceanapia Norman, 1869 comprises 95 species worldwide, 20 from the Atlantic Ocean and seven from Brazil. Oceanapia includes sponges with hollow body and numerous fistulae; spicules are oxeas or strongyles and microscleres, if present, are sigmas or toxas. Specimens were collected by trawl at Rio Grande do Norte, Pernambuco and Pará States, Brazil. Two new species are described from the Northeast Region of Brazil: Oceanapia cordia sp. nov. and Oceanapia magna sp. nov. For two preoccupied combinations, new names are proposed, Oceanapia hechteli nom. nov. and Oceanapia topsenti nom. nov. Oceanapia stalagmitica (Wiedenmayer, 1977) is recorded and described for the first time from Brazil. A taxonomic study of seven specimens of Oceanapia from the North and Northeast region (Brazil) is given, including description, illustrations and geographical distribution. The two new species are compared with all other descriptions of Oceanapia from the Atlantic Ocean.

Some regions, such as the Northeast Region of Brazil, are still severely understudied and the trichopteran fauna of this region is not entirely known, mainly in areas from Cerrado and Caatinga biomes. Currently, 25 species have been reported from Piauí State, but most of these records are concentrated from one locality. This study aimed to update the knowledge of Trichoptera diversity in this state, including the description of a new species and new geographic records for the Northeast region and Brazil. The samples were collected in seven municipalities, using various traps. Specimens were also received from the municipality of Bom Jesus. Thirty-two species were added for Trichoptera fauna of Piauí, 14 of these represent new records for Northeast Brazil; furthermore, Neotrichia palma Flint 1982 is a new record for Brazil. Additionally, a new species, Cernotina longa sp. nov., is describe and illustrate, being the third nominal record of the genus for the Caatinga biome. Thus, with the contribution of this study, 57 species, 20 genera and seven families of caddisflies are known for Piauí State.

Although the world species diversity of Marilia Müller 1880 is not great, knowledge about this group may be underestimated, since several areas are poorly studied, especially in Northeast Region, Brazil. Two new species are described and illustrated here based on specimens collected in Maranhão State, from which the genus has not been reported previously. Despite the similarity of Marilia caramuru sp. nov. with M. elongata Martynov 1912, differences between them are observed especially in segment X and preanal appendages, in addition to details of wing venation. The unique set of spiniform projections on endotheca, and the wrinkled prominence on sternum VIII distinguish Marilia paraguassu sp. nov. from all other species in the genus. The material examined has been deposited in the Coleção Entomológica Professor José Alfredo Pinheiro Dutra, UFRJ, Rio de Janeiro, Brazil, and in the Coleção Zoológica do Maranhão, UEMA, Maranhão, Brazil.

We describe and illustrate the pupa, larva, and both adults of a new species in the genus Araucnephia Wygodzinsky &Coscarón, 1973 (A. cearensis nov. sp.). The species was found in a highland area in Ceará State, Northeast Brazil. The pupa canbe separated from those of other Araucnephia pupae based on the number of gill filaments, which range from 25 to 35 branches(versus 9 or 14), and by it being completely encased by the cocoon. The larva can be separated from those of other Araucnephiabased on the presence of a median accessory anal sclerite. Adults are typical of the genus. This species extends the northern range of the genus Araucnephia, which is postulated to be Gondwanan in origin.

Cosmarium bahianum sp. nov. is described from samples collected from a bromeliad tank (phytotelmata) in a “restinga” area located at Salvador, Bahia State, northeast Brazil. Cosmarium bahianum belongs to the group of placoderm desmids, and is mainly characterized by rather small, smooth-walled, but remarkably punctate cells that are elliptic to subtriangular in apical view, as well as by a globose to elliptical, smooth-walled zygospore. The new species was collected from Hohenbergia littoralis J.B.Smith, an endangered endemic bromeliad species from the Brazilian Restinga with distribution restricted to the north coast of Bahia. The relationship of C. bahianum with morphologically similar species is discussed.

Cyanocyclas brasiliana (Deshayes, 1854) known only from the original very short description and reported from Pará state was recently rediscovered. This is the first occurrence of a native species of Cyrenidae (formerly Corbiculidae) in the Northeast Region of Brazil. Due to a lack of previous data C. brasiliana was initially confused with Corbicula largillierti (Philippi, 1844), an invasive species of Asian origin, which was introduced in South America in the 1970s and already recorded from the North and Northeast regions of Brazil. Ecological aspects are described. To aid identification, type material was studied.

O. Mendonça, Aptroot & M. Cáceres, with thallus yellowish brown, corticate, partly with a layer of whitish pruina, with (often eroded) pseudocyphellae, ascomata flattened to subglobose, numerous, partly covered by a layer of whitish pruina, 0.3–0.5 mm diam., mostly with 2–10 sideways touching but not totally fused, clypeus in upper half much thicker than below, ascospores 3-septate, 26–33 × 11–16 µm, lumina mostly obliquely quadrangular; Pyrenula lilacina C. O. Mendonça, Aptroot & M. Cáceres, with lilac thallus, simple ascomata, and ascospores 3-septate, 31–37 × 11–14 µm; Pyrenula supralaetior C.O. Mendonça, Aptroot & M. Cáceres, which is similar to P. laetior Müll. Arg., but with ascospores 25–31 × 11–13 µm; and Pyrenula violaceastroidea C. O. Mendonça, Aptroot & M. Cáceres, with ascomata pyriform, aggregated by 3–6 perithecia with a shared ostiole but without joint walls (parmentarioid), ostiole, ascomata and thallus partly covered by wine-red to purplish, KOH+ purple, anthraquinone. They were all found by the first author during several recent field trips in the North and Northeast of Brazil.

Com este trabalho foi possível estabelecer relações entre a quantidade de água aplicada e produtividade de grãos, para três variedades de feijão caupi submetidas a diferentes lâminas de água. Para caracterização das lâminas de água foi utilizado um sistema de irrigação por aspersão convencional em linha. O controle da irrigação foi realizado a partir de tensiômetros instalados à 15 cm de profundidade. Os resultados mostraram que: i) a cultivar João Paulo II apresentou melhores resultados de produtividade para as lâminas de água aplicadas que variaram de T1 = 291,8 mm a T5 = 141,2 mm; ii) sob condições de reduzida disponibilidade de água, ou seja, menor lâmina aplicada, não ocorreu diferença estatística  para a produtividade entre as cultivares estudadas; e iii) para as condições do estudo, a cultivar Setentão apresentou a menor taxa de redução do produto marginal.       UNITERMOS: caupi, irrigação, função de produção       LIMA, G. P. B., AGUIAR, J. V., COSTA, R. N. T., PAZ, V. P. S. Responses OF cowpea cultivars (Vigna unguiculata L Walp) at differents irrigation deficits     2 ABSTRACT       The caupi is one of the most traditional cultivation of the north and northeast - Brazil, constituting a basic food in these areas. With this work it was possible to establish relationships between the amount of water applied and productivity of grains, for three caupi varieties submitted to different irrigation sheets. To diferentiate water depths in the irrigation system, the aspersion in line was used. The control of the irrigation was accomplished using tensiometers installed to 15 cm of depth. The results showed that: i) the João Paulo II variety presented better productivity for the applied water depths; ii) under reduced conditions of water avai lability for study conditions, these was no significant difference in the productivity reached among the cultivars studied; and iii) for the conditions of the study, the variety Setentão presented the smallest rate of reduction of the marginal product.       KEYWORDS: cowpea, irrigation, production function
