Note
|
Paradrymonia lineata is distinguished by having narrow glabrous leaves, and striped corolla. It is most closely related to P. lurida of Costa Rica, which differs mainly in having the corolla lobes maroon spotted, and not glandular ciliate. This species is known from the provinces of Cocle and Veraguas.
