The species of the group rubripes, which harbors the type species of the genus Corinna C. L. Koch, 1842, are revised, including 20 Neotropical species. Three previously known species are re-diagnosed: Corinna rubripes C. L. Koch, 1842, Corinna nitens (Keyserling, 1891) and Corinna mourai Bonaldo, 2000. New records of Corinna nitens are provided, including the first ones from Peru and Bolivia. S...

This paper treats the discovery of new species and new records of aleocharine beetles for the province of New Brunswick.

The following are the new species: Acrotona brachyoptera Klimaszewski & Webster, sp. n., Acrotona sphagnorum Klimaszewski & Webster, sp. n., Athet...

phytoplankton communities play a significant role in the oceanic biological pump by forming the base of the trophic structure. increase in nutrients loading affects spatial and temporal distribution of phytoplankton. this study examined the phytoplankton community structure and ecological indices in relation to nutrients dynamics in both estuarine and oceanic areas of ramisi-vanga systems along...

The Mesoamerican bee genus Mexalictus (Hymenoptera: Halictidae: Halictinae) is a group of rare bees which are found at high elevations from southern Arizona (USA) to Panama. The genus is revised using traditional taxonomic approaches. The following twenty one new species are described: M. albofasciatus Dumesh, n. sp., M. anatolii Dumesh, n. sp., M. astriatus Dumesh, n. sp., M. ayalai Dumesh, n....

Recent work in the collections at the New Zealand National Institute of Water and Atmospheric Research collections in Wellington has yielded 14 new diastylid species in five genera, Colurostylis whitireia n. sp., Diastylis acanthoelachys n. sp., D. adaioacanthus n. sp., D. curtain n. sp., D. dasys n. sp., D. enodis n. sp., D. homoacanthus n. sp., D. implanus n. sp., D. spinacellulosus n. sp., D...

Stenamma is a cryptic "leaf-litter" ant genus that occurs in mesic forest habitats throughout the Holarctic region, Central America, and part of northwestern South America (Colombia and Ecuador). The genus was thought to be restricted primarily to the temperate zone, but recent collecting efforts have uncovered a large radiation of Neotropical forms, which rival the Holarctic species in terms o...
