Remarks.
This species has a compressed, asymmetrical cephalis, which is longer than it is wide. It differs from
L. ehrenbergi
(Pl. 15,
Figs. 7A–C
) in that it does not have an extended neck, and differs from
L. mitra
(Pl. 15,
Figs. 4A
–
6
) in that cephalis is not round. The large, framed pores differentiate this species from
L. alkonost
n. sp.
(Pl. 16,
Figs. 1A
–
7B
) and
L. sirin
n. sp.
(Pl. 17,
Figs. 1
–11B). Thus, this species does not seem to fit in any of the species categories for far described, but here we leave it in open nomenclature until a better understanding of its variability can be reached.
