Guyalna bogotana ( Distant, 1892) , new record

Fidicina bogotana Distant 1892a: 58 . (Bogotá, Colombia)

Remarks. The species has a greenish tawny head and thorax with ochraceous abdomen with minimal mesothoracic and head markings that is very similar in general appearance to Dorisiana metcalfi Sanborn & Heath, 2014 of the Venezuelan fauna. However, the presence of a curved anterior timbal cover with a ventral margin parallel to the long body axis distinguishes it as a species of Guyalna rather than Dorisiana ( Sanborn 2016c) . The male abdominal tergites are translucent and body lengths range from 24–26 mm.

Guyalna bogotana can be distinguished from the other Venezuelan species of Guyalna (all illustrated in Sanborn 2016c) by the brightly infuscated basal areas of the wings and the bronzed distal apical cells in the larger (body length 32 mm) of G. atalapae Boulard & Martinelli, 2011 and the ochraceous pronotum contrasting the remaining fuscous body, larger body size (26–31 mm), and the infuscation on the ambient wing veins quickly distinguish G. flavipronotum ( Sanborn, 2007) . The most similar Venezuelan species is G. distanti ( Goding, 1925) but it can be distinguished quickly by the piceous markings forming connected arches across the dorsal abdominal tergites and the transverse piceous fascia on the head found in that species.

Distribution. The species has been reported previously from Argentina, Brazil, Colombia, Ecuador, Panama, and Peru ( Metcalf 1963a; Sanborn 2013; 2018; 2020; Sanborn & Heath 2014). The range is expanded northeasterly here to include Venezuela.
