This new species morphologically resembles P. fangianus (Y.G.Wei) J.M.Li & Yin Z.Wang, but it can be easily distinguished from the latter by having peduncles and pedicels puberulent, corolla outside sparsely puberulent, shorter tube 18–20 mm long, orifice from throat to the interior smooth, without protuberances, and lacks nectar guides. The conservation status of P. paradelphinius can be assessed provisionally as Critically Endangered [CR B2b(ii, v) + C2(a, i)]. %M doi:10.6165/tai.2024.69.491
