FIGURED SPECIMEN. — ULVG-7331.

MATERIAL. — Five specimens (recovered with the hydrogen peroxide method).

OCCURRENCE. — Maastrichtian of California (Campbell & Clark 1944; Foreman 1968); Campanian of Turkey ( Moix et al. 2009).

REMARKS

This species was not assigned to? Lithomelissa hoplites Foreman, 1968 due the absence of ridges extending from the apical horn on to the cephalis, as well as the absence of upward-directed spiny projections on these ridges. Likewise,? L. hoplites possesses a poreless cephalis and dorsal and primary wings extended from the three edges of the triangular thorax ( Foreman 1968).
