Resumen:
Norman (1879) erected the genus Chalarostylis to accommodate C. elegans, a new species he described based on a single adult male collected off Rockall, North East Atlantic (199 m). This old description consists of a short text, with no accompanying figures. In addition, this specimen has its first pereopod broken off at the basis-ischium articulation. Gerken & McCarthy (2007) redescribed and illustrated C. elegans based on the re-examination of the male holotype and a female collected off the Porcupine Bank (1564 m). This female has a robust first pereopod bearing a brush of setae on its dactylus. Based on this information, Gerken & McCarthy (2007) emended the diagnosis of the genus and transferred Dasylamprops guanchi Reyss, 1978 from the Canary Islands to Chalarostylis, becoming C. guanchi the second species of the genus. In the present contribution Hemilamprops brenkei Mühlenhardt-Siegel, 2005 is partially redescribed, and since this species also has a strong first pereopod, it is transferred to the genus Chalarostylis as well. Two other species until now in Hemilamprops, i.e., H. canadensis Vassilenko, 1988 and H. longisetae Corbera, 2006 are also transferred to Chalarostylis. In addition, an unknown species of Chalarostylis from the Bay of Biscay (2138 ? 2246 m), provisionally identified as Chalarostylis sp. A, is briefly described. Finally, the diagnosis of the genus is emended.
