Sanborn, Allen F., 2011, A New Species of Orellana Distant from Brazil (Hemiptera: Cicadoidea: Cicadidae), Proceedings of the Entomological Society of Washington 113 (3), pp. 377-384 : 378

Key to the Species of Orellana

The species O. brunneipennis and O. pulla are included in the key even though their generic placement is uncertain ( Goemans 2010). The descriptions of these species and key in Goding (1925) were used to form the couplets for these species as no specimens were available to the author.

1. Forewings hyaline............................................... O. castaneamaculata

– Forewings opaque or with fuscous spots....... 2

2. Forewings with fuscous spots............... 3

– Forewings primarily opaque................ 5

3. Forewings with an ochraceous hue and fuscous spots; cruciform elevation of mesonotum not humped laterally between anterior and posterior arms; abdomen expanding posteriorly from base becoming widest in middle................. O. columbia

– Forewings hyaline with fuscous spots; cruciform elevation of mesonotum humped laterally between anterior and posterior arms ( Figs. 3 , 12 ); abdomen with sides parallel from base to middle............ ..................................... 4
