Malawidopsis gen. nov. fuelleborni comb. nov. ( Daday, 1910) (= spec. N)

Fig. 18N

Abbreviated description: elongated Cp, with almost symmetrically rounded anterior margin and bluntly pointed posterior margin, dorsal margin sloping towards the posterior side, ventral margin nearly straight. RV mildly overlapping LV along the antero-dorsal and postero-ventral margins. In dorsal view Cp relatively wide, with greatest width situated slightly behind the middle. Whole Cp densely set with small tubercles.

Measurements: length of female = 707–730 µm; length of male = 691 µm.

Localities.

Original localities of Malawidopsis fuelleborni ( Daday, 1910) . No further information available, but it is assumed that all samples were taken from the shallow littoral.
