Material: 5 specimens in total. Anda1 (3) RGM 962141, RGM 962341; AndaDeVos (1) RGM 962142; Roxas (1) RGM 962145 .

Two adult specimens were identified (OL:OH=1.34). They closely resemble the Recent species Lobianchia gemellarii . They differ from Diaphus rafinesquii (Cocco, 1938) by a less expanded dorsal field and a small antirostrum. Together with a poorly developed excisural notch, the ostium/cauda ratio is larger in L. gemellarii than in D. rafinesquii . Three juvenile specimens also fit well within this species.
