Trubovitz, Sarah, Renaudie, Johan, Lazarus, David & Noble, Paula, 2022, Late Neogene Lophophaenidae (Nassellaria, Radiolaria) from the eastern equatorial Pacific, Zootaxa 5160 (1), pp. 1-158 : 84

Pelagomanes? sp. B

Plate 42, Figs. 1A – 3 .

Remarks. It is not clear to us whether all of these specimens are conspecific, or that they should certainly be included in Pelagomanes . These specimens are small, and have a relatively large and rounded cephalis, with usually more numerous pores compared to the other taxa included in this genus. The thorax is very short, only slightly longer than the height of the cephalis, and terminates with at least size strong, sometimes bladed feet. There is a distinct hyaline zone near the base of the thorax, where the pores stop and the feet begin. One specimen (fig. 2) has an enclosed base.

Material examined. 4 specimens observed from samples 321-1337D-30H- 3, 103–104cm (Middle Miocene) and 321-1337D-26H-3W, 142–144cm (Late Miocene).

Range. Middle–Late Miocene in the EEP, range not well constrained ( Table 1 ).

Figures

FIGURE 1. Diagram illustrating the general skeletal morphology of Lophophaenidae, and terminology used in this manuscript. Dashed lines indicate spines that are not visible from the angle shown, as they extend into the skeleton. An example specimen of Lophophaena casperi n. sp. is included for comparison to the diagrams.
