Maize (Zea mays L.) is the staple diet of the native peasants in the Quechua region of the Peruvian Andes who continue growing it in small plots called chacras following ancestral traditions. The abundance and structure of bacterial communities associated with the roots of amilaceous maize has not been studied in Andean chacras. Accordingly, the main objective of this study was to describe the ...

Based on examination of holotypes or interpretation of original descriptions, four taxonomic changes are proposed for South American species erroneously placed in the tribe Smiliini: Flynnia, gen. n. (Thuridini) and F. fascipennis (Funkhouser), comb. n. from Bolivia; Antianthe atromarginata (Goding), comb. n. from Ecuador; Amastris pilosa (Funkhouser), comb. n. from Peru; and Thelia planeflava ...

Background Although many new species to science have been discovered from thousands of specimens resulting from botanical inventories to support conservation management in Cameroon in recent years, additional species remain to be formally evaluated taxonomically and described. These include species from genera which have been taxonomically neglected for many decades in Africa, such as Microcos....

Three new species of Tegano are described, two from caves on Panglao Island, Bohol, Philippines, and one from a cave on Peleliu Island, Palau. Sriha vagabunda from Sri Lanka is reassigned to the genus Tegano based primarily on the high degree of similarity between Sriha vagabunda and species of Tegano and the fact that these species exhibit a great deal of variation in the reduction of the mand...

Two micropterous species of Paederus Fabricius, 1775 from East Nepal are described and illustrated: (incertae sedis) digitalis spec. nov. P . acifer They distinguished other geographically close congeners. Including the new species, fauna currently includes 37 24 them exclusive. Additional records two widespread reported Chinese province Yunnan Vietnam.

Trischidocera Villeneuve, 1915 includes two species, T. sauteri Villeneuve, 1915 (Taiwan and Malaysia) and T. yunnanensis Chao & Zhou, 1987 (China). The systematic placement of Trischidocera has been controversial. It was originally placed within the "Thryptoceratidae" (= "Actiidae"), then moved to Germariini, then considered an unplaced Tachinidae, and more recently placed in Ormiini. Here, th...

Nine genera and twenty-two species of heptageniid mayflies from Thailand are defined in this present work as well as one suggested further subgenus, Compsoneuria (Siamoneuria) kovaci (species "incertae sedis") including some particular characters. Taxonomic remarks, diagnoses, line drawings of key characters, distribution, habitat and biological data, and a larval key to the genera and species ...

Seven species of holothurians of the family Psychropotidae were collected during the cruise D300 of RRS Discovery to Crozet plateau. Three of them, Benthodytes wolffi, Psycheotrephes discoveryi and Psychropotes xenochromata are described as new to science. One species, Benthodytes abyssicola Théel, regarded recently as incertae sedis, is redescribed with designation of a lectotype. Additional n...
