Taxonomic hypotheses of <i>Petaurista.</i>

a<p>Ellerman (1940) recognized 31 species, 14 of which (P. cineraceus, P. lylei, P. mergulus, P. annamensis, P. candidulus, P. taylori, P. fulvinus, P. inornatus, P. birrelli, P. gorkhali, P. melanopterus, P. sulcatus, P. rubicundus and P. filchnerinae) have not been recognized as valid Petaurista species by any other researcher.</p

Genetic differences of <i>Petaurista</i> taxa based on pairwise comparisons of complete cytochrome <i>b</i> gene sequences (1,140 bp).

<p>Data above the diagonal represent the transversional percentage differences of the 3rd codon position of sequences among taxa. Data below the diagonal are the percentage differences of sequences among taxa.</p
