Remarks. Hausdorf (pers. comm.) considers, given the variability of both species, P. delicatus as a synonym of P. succineoides (Petit de la Saussaye, 1840). However, we do find consistent differences between the two and treat them here as separate taxa. P. delicatus has been found on and among cacti ( Opuntia spp.), and other plants typical of semi-arid conditions ( Solanum lycioides , Agave sp., and Puya sp.).
