“…Its occurrence on the Balkans is uncertain, but it has been found in Southern Spain, and records from Corsica and Sardinia (Stella et al 1972;Margaritora et al 1975) are also likely correct. The situation on continental Southern Italy is unknown (Margaritora 1979 does not present conclusive data). …”

The group of hyponeustonic daphniid cladocera previously known under the generic name Scapholeberis is raised to the rank of a subfamily (Scapholeberinae) and contains two genera, Megafenestra n.gen. (2 species), and Scapholeberis s.s. (7 species and one subspecies). The characters upon which this revision is based are: structure of the rostrum, structure of the first antennae, structure of trunk limbs 1, 2, and 5, presence and nature of headpore(s), structure of the ventral rim of the valves, armature of the distal rim of the valves, structure of the postabdomen and its end-claws. Males were examined in all but two species, and proved to be more primitive than females and much less diagnostic than in the Chydoridae. It also appeared that the shape and armature of the postabdomen are less important taxonomical tools than heretofore supposed. In more than half of the species, it is of generalised shape and hardly usable beyond the species-group level. The same, although less drastically, holds true for the P 1 of males. Of greatest diagnostic value at the species level are the shape of the rostrum and the armature of the valve margins.

“…hispanica is a typical steppe species . It appears in waters having characteristic taxa of temporary and not highly mineralized waters in arid and semiarid regions as Triops cancriformis, Mixodiaptomus incrassatus, Hemidiaptomus roubaui and Ehemeroporus phintonicus (Gauthier, 1928 ;Margaritora, 1979 ;Alonso & Comelles, 1984) .…”

Daphnia (C .) hispanica n . sp . has thoracic limbs ofA`D. (C.) atkinsoni type' and is very similar to D . chevreuxi Richard, 1896 . With this species D . (C.) hispanica shares the presence of a soft accessory seta on the outer side of the trunk of the first thoracic limb, apparently unique among the genus Daphnia . Although other morphological characteristics are very similar in this two species, a detailed comparison reveals that they can easily be separated as different species . The most useful features in differentiating both species are : D . (C.) hispanica has a dorsal crest in the head, its rostrum is longer, its accesory seta of the first thoracic limb is more developed, the juveniles are not helmeted and its male postabdomen lacks individual denticles on the anal and preanal margin .The new species is, up to now, restricted to Spain and inhabits the temporary and low mineralized waters of the steppe regions .
