    Notes: Abstract A collection of freshwater ostracods from the Sudan is studied and 18 species are recorded. Paracypretta amati sp.n. is new to science. A redescription of the holotype female of Paracypretta aratra (Brady, 1904) (not recorded in this collection) and a provisional key to the species of Paracypretta are given. Heterocypris giesbrechtii (G. W. Müller, 1898) is re-described; Heterocypris sobrinus (Masi, 1932) is placed in the synonymy of H. fretensis; Hemicypris intermedia (Lindroth, 1953) is recorded for the first time since its original description and is redescribed, while Cyprinotus largereticulatus Rome, 1969 is transferred to Hemicypris. The zoogeographical composition of this fauna is briefly discussed.

    Notes: Abstract Twenty-one species of dragonflies are recorded from the Nile and the Red Sea Hills in the Sudan. The majority are species of africotropical origin, but wide-ranging and tolerant of strongly fluctuating environmental conditions. A small but significant fraction is restricted to the Nile Valley, and another fraction, found only in the Red Sea Hills, is composed of Eremian species of Palaearctic origin. Besides adults, the last-instar larvae of Pseudogrion niloticum and of Paragomphus pumilio are described and figured.
