Based on the hypothesis of parapatric speciation between Panopea generosa and Panopea globosa, nuclear genes were used to provide molecular evidence of ancient phylogeny between them, and included other species of the genus for a broader comparison.
Because of their extreme similarity in appearance and habits and their largely parapatric distribution, they appear to be an excellent candidate system in which to study the genomics of a high-latitude cryptic (Bickford et al.
Firsthand experience with and knowledge of the seasonal male advertisement call characteristics is also important so it can be distinguished with certainty from the other natural "trilling" sounds produced by sympatric or parapatric species (red-spotted toad, Anaxyrus punctatus; Lesser Nighthawk, Chordeiles acutipennis; and possibly insects).

It is possible that additional new species may occur here as parapatric segregates, as seems to be the case with H.

There are approximately 30 parapatric races that mate randomly in narrow hybridization zones (Emsley 1964; Mallet 1986).
The two species show a parapatric distribution on the whole with a contact zone formed at the boundary of their ranges across the big turning of the Yellow River in the central-western part of Inner Mongolia, Ningxia and the middle part of the Gansu Province.
More specifically, Geomys bursarius is parapatric with Thomomys talpoides, Thomomys bottae, and Cratogeomys castanops; T.
The number of supralabials in blind snakes is a genetically conservative character, and any 1/2 condition of the supralabials of any individual may represent one of two possibilities: (1) an aberrant condition (seen rarely within the species) or (2) a hybrid between two species with parapatric distributions.
