Notodromas monacha (O.F. Müller, 1776)

( Fig. 6 )

Generic Differential Diagnosis (modified after Meisch 2000): Carapace rounded in lateral view, with strong sexual dimorphism in shape and structure. Eye-cups clearly visible, but less prominent than in the Newnhamia . Male valves with pointed caudal margin and without flap-like structure on LV ( Figs. 6 A-F). Female valves with posterior margin evenly rounded ( Figs. 6G, H, J, K ); LV with postero-ventral flap-like structure ( Figs. 6J, L, M ). Carapace in dorsal and ventral views ( Fig. 6C, E, I, L ) evenly rounded, with greatest width in the middle, RV only very weakly overlapping LV, both valves in fact subequal. Plate-like ventral expansion almost as long as entire CP, but set with few ridges; antero-ventral lip-like expansions prominent. T 2 without d-setae, flanking setae longer than half the length of the end claw. T 3 with terminal segment separate from penultimate segment. Caudal ramus without distal seta.

Type locality and Type material: unknown (see Karanovic 2012)

Material examined here: Pool near “Buikske Rond”, Destelbergen, Oost-Vlaanderen, Belgium (coordinates: 51°03'12.3"N, 3°49'16.3"E). Collected on 1/6/2011 by K. Martens and J. Higuti.

Remarks: Gurayacypris Battish, 1987 is most likely a junior synonym of Notodromas .
