REMARKS.—The genus was erected as part of a taxonomic key and originally included only two species (
Boulard & Martinelli 1996
). A revision of the genus recently published provided a full generic description and reassigned several species into and out of the genus (
Sanborn 2016a
). Within the
Guyalnina
, the species of
Guylana
can be distinguished by having a combination of the absence of bright green basal area of the fore wings and bright red basal areas of the hind wings, the parallel radial and radiomedial crossveins, a head width as wide as or slightly wider than the mesonotum, without prominent stylate and anteriorly extended eyes and eyes that only slightly project laterally beyond the anterior edges of pronotum, the absence of triangular or curved timbal covers, male opercula that generally form a right triangle, and triangular or small, curved timbal covers. The genus
Dorisiana
is the most similar to
Guyalna
but species of
Dorisiana
can be distinguished by the head being as wide or wider than the mesonotum with eyes not extending beyond the lateral edges of the pronotum, triangular timbal covers, the ventral margin of the timbal cover angled dorsally rather than being parallel to the long body axis, and the lateral lobe of the uncus does not extend to the same lengths in species of
Dorisiana
as it does in the species of
Guyalna
(
Sanborn 2016a
)
.
