Diagnosis | |
Comment | Subspecies: FERIA-ORTIZ et al. 2011 provide evidence that P. b. brevirostris, P. b. bilineatus, P. b. dicei, and the eastern populations of P. b indubitus (from Morelos, Guerrero, and México) represent distinct species, whereas the western populations of P. b. indubitus (from Colima and Jalisco) represent an undescribed species. The data cannot resolve whether P. b. pineus is conspecific with P. b. dicei or P. b. dicei is a paraphyletic ( = nonexclusive) species relative to an exclusive P. b. pineus. Thus, the status of P. b. pineus remains uncertain. The haplotype phylogeny also suggests that P. b. brevirostris may represent more than one species. BRANDLEY et al. (2012) showed that bilineatus, dicei, and indubitus are paraphyletic with respect to other species and thus need to be split up. |
Etymology | From the Latin bilīneātus meaning doubly lined in allusion to its coloration. |
