The males of three new species of Oukuriella Epler are described from Costa Rica . The genus had been previously recorded only from South America. Oukuriella annamae sp . nov. has genitalia similar to O . albistyla Epler, but differs in having transverse bands on abdominal segments III, IV, VI and VII, a lower AR, no humeral setae and fewer dorsocentral setae . Oukuriella costaricense sp . nov . differs from other described species in the genus by its brown abdomen, unnotched posterior margin of tergite IX and distinctive superior volsella, with its sharply bent, thin upper arm directed medially, and digitus small and directed caudad . Oukuriella rushi sp . nov. has apices of femora tipped with brown, a brown abdomen and distinctive superior volsella, with upper arm shorter and broader, and digitus longer then O . costaricense . The female of Oukuriella costaricense is also described . This is the first female described for the genus . Based on male and female genitalia, Oukuriella is closely related to Epedilum Townes and Zavreliella Kieffer. A key is provided to separate the males of the six described species .

“…Chironomidae found in freshwater sponges in the River Paraná, reservoirs in the State of São Paulo, and in Amazonian streams have many unusual larvae with strongly sclerotised structures, which make the identification very difficult. After rearing the larvae in laboratory to obtain pupae and adults, we identified them as belonging to Oukuriella Epler, 1986. The specimens are deposited in the collection of the Laboratório de Entomologia Aquática da Universidade Federal de São Carlos (SP) and Coleção Entomológica do Instituto Nacional de Pesquisas da Amazônia, Manaus (AM), Brazil.…”

This study was the first attempt to resolve both spatial and temporal patterns of macroinvertebrate trophic dynamics in a Chinese subtropical river continuum, the Shengli River, from 1st to 4th order. Gut content analysis was adopted to assess the trophic basis and consumption rates of communities. Furthermore, annual energy flow food webs were constructed. Trophic basis analyses showed that 34–79% of the diet of macrozoobenthos in the Shengli River and its tributaries was amorphous detritus. Leaf litter was the second most important food source, followed by animal material. Filamentous algae, diatoms, and fungi served only as subsidies, contributing no more than 5% to total consumption. The macroinvertebrates in 1st and 3rd order streams appeared to show seasonal consumption patterns of different food types, while the communities in 2nd and 4th order streams had the same diet composition throughout the year. Total consumption rates of the communities increased from 1st to 3rd order streams, and declined in 4th order streams. The energy flow food web of 1st order streams was simpler than those of higher‐order streams. With increasing stream order, the food webs increased in complexity until 3rd order, and became simpler again in 4th order streams.
