A new species of sponge-dwelling Oukuriella (Chironomidae) from Brazil.

Oukuriella Epler, 1986 is an exclusively Neotropical genus that comprises two well supported clades: inhabitants of freshwater sponges and inhabitants of immersed wood (saproxylophilic). In this work, males of a new chironomid species, Oukuriella froehlichi sp. n., are described and illustrated. Specimens were collected near stream in the Brazilian Atlantic Forest. Phylogenetic analyses perform...

A New Diketopiperazine from the Marine Sponge Callyspongia Species

Chemical investigation of the sponge Callyspongia sp. from the South China Sea afforded one new diketopiperazine, cyclo-(R-Pro-6-hydroxyl-S-Ile) (1), along with six known diketopiperazines: staphyloamide A (2), cyclo(S-Pro-S-Phe) (3), cyclo-(R-Pro-R-Phe) (4), cyclo-(S-Pro-R-Leu) (5), cyclo-(S-Pro-R-Ala) (6), cyclo(R-Tyr-R-Phe) (7), and three known tryptophan-derived alkaloids: C 2 -α-D-mannosyl...

New species of the endemic Neotropical caddisfly genus Contulma from the Andes of Ecuador (Trichoptera: Anomalopsychidae)

The genus Contulma Flint (Trichoptera: Anomalopsychidae) is composed mostly of regionally endemic species occurring above 2,000 m, with a few more widespread species and some that are found at lower elevations. Adults of three new species of Contulma are described and illustrated from the Andes of Ecuador, Contulma lina, new species, Contulma quito, new species, and Contulma sangay, new species...
