Two species of the weevil genus Compsus Schoenherr (Coleoptera: Curculionidae: Entiminae) from Colombia are redescribed: C. obliquatus Hustache and C.viridivittatus (Guérin-Méneville). A key by Hustache in 1938, to 33 of the 34 recognized species of Colombian Compsus then known, is modified to include the one additional species. Habitus illustrations of males and females of the two species and illustrations of selected parts of the male and female genitalia are included. Nearly all of the specimens of these two species were collected on various species or varieties of citrus, indicating their potential as citrus pests in the future.
Two new species of the genus Pahamunaya Schmid (Trichoptera: Polycentropodidae), P. talon sp. n. and P. spinifera sp. n., from Vietnam are described and illustrated. Examination of the holotype male of P. khoii Oláh and Johanson, in combination with an additional specimen of the same species, revealed new characters. New illustrations for this species are provided.
The development of and the changes in the classification of bryophytes are shown over the last two centuries. It is shown that, except for an early period, the bryophyte system was never totally revised but was always only slightly improved, in which the ideas of a bryophyte system has undergone some kind of evolution but was never drastically changed. Neither the evolution theory in the last century nor the results of cytology, phytochemistry, computerbased studies or genetics in this century had drastically altered the bryophyte system. The reasons for the never totally changed but always slightly improved classification of bryophytes seem to be that recognition of systematic units is based on certain principles such as hierachical classification, types and algorithms of comparison. Therefore it is postulated that no general changes in the classification of bryophytes are to be expected in the future.
The mirine plant bug Tropidosteptes forestierae, new species (Hemiptera: Miridae) is described from
Collier County, Florida, where it was found causing serious injury to an extensive ornamental hedge of Florida swampprivet, Forestiera segregata (Jacq.) Krug and Urb. (Oleaceae). Adult male and female, fifth instar, and egg are described. Color images of the adults, nymph, egg, and injury; scanning photomicrographs of selected adult structures; and illustrations of male genitalia are provided. A key to help distinguish the 16 species of Tropidosteptes known to occur in the southeastern United States is given.
Three new species of Helicopsyche Siebold, 1856 are described from Vietnam: Helicopsyche melina sp. nov., Helicopsyche meander sp. nov., and Helicopsyche lamnata sp. nov. All species were described from Melinh Station for Biodiversity in the Me Linh District of Vinh Phuc Province. The species were collected mainly in Malaise traps situated across a small stream surrounded by lowland forest. Some individuals were also collected on light in traps situated at the stream bank.
Three new species of Eupetersia Blüthgen, 1928 (Hymenoptera, Halictidae) from the Oriental Region
(2012)
Three new species, Eupetersia (Nesoeupetersia) singaporensis sp. nov., collected in a mangrove swamp in Singapore, and Eupetersia (Nesoeupetersia) sabahensis sp. nov., collected in the mountains of Sabah, Borneo, and Eupetersia (Nesoeupetersia) yanegai sp. nov., collected in Thailand, are described. This genus is more diversified in the sub-Saharan region, including Madagascar. The only other Oriental species, E. nathani (Baker, 1974), was described from India and is diagnosed and re-illustrated here.
