Remarks. Strouhal (1968) had described this species as Bathytropa wahrmani and included it in the family Bathytropidae , which is definitely not correct because a diagnostic feature of this family is the absence of lungs from all pleopods (see Schmidt 2003), while this species has distinct uncovered lungs on pleopod exopodites. Also the hour-glass-shaped telson is a distinguishing character from all the other species of Bathytropa . This species is similar to the two new species from Cyprus described above, especially in the interlocking pleopods and in the same structure of the pleopodal lungs. It is therefore transferred to the new genus Levantoniscus and family Trachelipodidae .

The species is here fully illustrated ( Figs 9 View FIGURE 9 , 10 View FIGURE 10 ) for comparison with Levantoniscus bicostulatus and L. makrisi , from which it is readily distinguished by the pattern of dorsal ornamentation ( Fig. 9 View FIGURE 9 A, B). In particular, it has a row of four pointed tubercles at the back of the head instead of two in the new species, a couple of forward-pointed tubercles on the front of the head which are lacking in the new species, plus a narrower and acuter middle frontal lobe on the cephalon ( Fig. 9 View FIGURE 9 D–F). Seven pointed tubercles are present on the pereonite 1, six on pereonites 2–4 and four on pereonites 5–7, while the two new species only have two lamellar tubercles on all pereonites. Finally, it has two tubercles on pleonites 1–5, while the new species have two tubercles on pleonites 1–4.

In the detailed description provided by Strouhal (1968) there is no mention on the position of the noduli laterales. They are located on the tip of the external tubercle on the pereonites 1–4 and on the postero-lateral corners of the pereonites 5–7 (see Fig. 9 View FIGURE 9 A, B).
