Pteronymia tigranes (Godman & Salvin)

Male dorsal

Male ventral

Female dorsal

Female ventral

Smaller than P. artena, costa of dorsal forewing entirely black, hindwing fringe scales black, postdiscal bar wide, M2 all black, fringe of hindwing black.

Wingspan: 50-52mm

Forewing length: 25-27mm

Local distribution: On Pacific slope at 1100-1500 m; Atlantic slope at 700-1200 m.

Similar species: Pteronymia artena, P. simplex, Hypoleria cassotis, Greta andromica

Species range: Costa Rica

Abundance: Uncommon

Larval host plants: Unknown

Early stages: Solitary

Comments: This species needs more study to determine if it is a form of P. artena associated with wet habitats (see DeVries 1987) or a distinct species. I have commonly found it to be sympatric with P. artena and consistently different in wing shape and pattern characters at Monteverde.
