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.

.
