Detail of head. I counted 42 antennal segments (including the scape and pedicel), rather than the 35 segments described for the male holotype of O. crepusculus on pg. 107 of Chandler (1954) . I'm presuming the number of antennal segments is not constant...or that this is a female (see 6th image in this series) and that they have more antennal segments (they are generally larger than males)...as, overall, that species seems the best fit among described species in the literature that I'm aware of. Comments, corrections, or confirmation are always welcome and encouraged!

For more info on this post, please see remarks under 1st image in series.
