Odontophotopsis (Odontophotopsis) biramosa Schuster, 1958 . Ent. Amer. (n. s.) 37: 56. Male.

Diagnosis of male. This species is recognized by having a tridentate mandible with an extremely large dorsal tooth that is separated from the lower portion of the mandibular apex by a deep, wide sinus, which makes the mandibular apices appear biramose (Fig. 29), and by the clypeus, which has a horseshoe-shaped tubercle posteromedially that overhangs the clypeus as a slight hood-like or nasutiform process. Also, this species has a single mesosternal process on each side of the midline, and its cuspis is approximately half the free length of the paramere. The genitalia are illustrated in Fig. 10.

Female. Unknown.
