REMARKS. Ariasa can be distinguished from Majeorona Distant, 1905d by the head width being wider than the mesonotum, with the prominent, stylate eyes that are extended anteriorly in Majeorona . The genera Proarna , Prasinosoma and Tympanoterpes all possess a head that is about as wide as the mesonotum with the eyes barely or not extending beyond the anterior angle of the pronotum, radial crossvein vertically oriented to the radius anterior 2 and radius posterior veins with a radiomedial crossvein that is obliquely oriented, large semicircular male opercula, and triangular or small, curved timbal covers. Guyalna Boulard & Martinelli, 1996 can be distinguished by the head being as wide or slightly wider than the mesonotum, eyes that only protrude slightly beyond the anterior angles of the pronotum, parallel sides of the abdomen, and the lateral branches of the uncus form a horse-shoe shape when viewed from the posterior. Dorisiana Metcalf, 1952 can be distinguished by species with a head being as wide or wider than the mesonotum with the eyes not extending beyond the lateral edges of the pronotum, triangular timbal covers, ventral margin of the timbal cover angled dorsally not parallel to the long body axis, and the lateral branches of the uncus are extended.
Ariasa is most similar to Cracenpsaltria Sanborn, 2016c but can be distinguished by the separate, long, hooked lateral branches of the uncus instead of a posteriorly extending median uncus lobe found in Ariasa , the pygofer distal shoulder is angled in the Cracenpsaltria , Cracenpsaltria lacks the laterally expanding abdominal segments, and the length of the abdomen is greater than the distance between the apex of the head and posterior cruciform elevation in Cracenpsaltria .
DISTRIBUTION. Species of the genus have been reported from Argentina, Bolivia, Brazil, Colombia, French Guiana, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela ( Metcalf 1963a; Sanborn 2011a; 2011b; 2013; 2016b; 2016c; Sanborn & Heath 2014).
