The following new taxa are described:Halictus (Monilapis) yunnanicus sp. nov. and Halictus (Protohalictus ) hedini hebeiensis subsp. nov. Synonymies H. takulylkus Bluthgen, 1936 = H. pseudotakuiricus Fan, 1990= H.zadaensis Fan, 1990 and Halictus palustris Morawitz, 1876 = H. frost us Fan, 1990 are ascertained. Halictus maculatus Smith and Halictus compressus (Walkenaer) are new records for China. Holotypes and most of the paratypes are deposited in the Institue of Zoology, Academia Sinica, Beijing; a few paratypes-in the Zoological Institute, Russian Academy of Sciences, St. Petersburg.

They are able to use at least three different sources of compass information, including solar, stellar and geomagnetic cues. However, little is known about how these cues are calibrated into uniform reference direction information, while the hierarchy of these cues remains controversial. In recent studies, researchers suggest that avian migrants calibrate their geomagnetic compass on sunset cues, whereas others fail to find such patterns and insist on the prevalence of the magnetic compass. We carefully reviewed the existing literature and suggest that the conflicting results reported by different authors are due to genuine variation among species and propose hypotheses to explain this variation.展开更多
