Odontophotopsis unicornis
Schuster, 1958
Odontophotopsis unicornis is a of ( ) described by Schuster in 1958. It belongs to the O. unicornis species-group, which contains two recognized species: O. unicornis and its sister species O. erebus. Molecular and morphological analyses support the validity of both species as distinct . The female of O. unicornis was previously unknown and was first associated with the male using molecular data.

Identification
Females of O. unicornis were historically unknown and were distinguished from O. erebus through molecular association with males. Males can be differentiated from O. erebus through morphological comparison, though specific diagnostic characters are not detailed in available sources.
Habitat
Arid and desert-adapted environments in North America.
Distribution
North desert regions.
Similar Taxa
- Odontophotopsis erebusSister within the same species-group; historically confused with O. unicornis but validated as distinct through molecular and morphological analysis.
More Details
Pleistocene Origin
Phylogeographic analyses using ITS1 and ITS2 rDNA regions and calibrated with Dominican amber fossils indicate that O. unicornis and O. erebus diverged approximately 1 million years ago during the middle Pleistocene. This represents one of the few documented cases of Pleistocene-aged -level divergence in desert-adapted North .
Lack of Phylogeographic Structure
of O. unicornis show little to no phylogeographic structuring, likely due to the relatively recent origin of the .
