Ocyptamus conjunctus . Thompson et al. (1976: 15).

Comments. This species does not fit the current definition of Ocyptamus . Preliminary morphological analyses place it close to Mimocalla species, but not all characters are in agreement with that taxon. Hull (1943b) erected the subgenus Therantha for the species Baccha atypica Curran, 1930a, a junior synonym of conjunctus Wiedemann, based on the elongate antenna, with each segment (scape, pedicel and basoflagellomere) subequal. Although there is an available generic name for this species, it is possible that it might still be allocated to one of the other taxa presented above in future analyses. Thus, it is left incertae sedis until more analyses can ascertain its position in the classification.
