Dorisiana bicolor Boulard 1996: 142 . Guyalna bicolor Sanborn 2016 : in press. Type locality. Cayenne , French Guiana . Remarks. The species was recently assigned to Guyalna ( Sanborn 2016 ) based on the three-segmented tarsi, rounded timbal cover apex ( Fig. 2 ), pronotum shorter than mesonotum, head as wide or slightly wider than the mesonotum and slightly protruding eyes as listed by Boulard & Martinelli (1996) as characteristic of the genus Guyalna . In addition, the lack of a cruciform elevation notched in the form of a more or less open semicircle as listed by Delétang (1919) as characteristic of Dorisiana and the lack of a tapered, triangular timbal cover listed as characteristic of Dorisiana by Boulard & Marinelli (1996) mean the species cannot be assigned to Dorisiana . Body length 19–23 mm , fore wing length 33–37 mm . Distribution. The species has been reported under various names from Brazil Colombia , Costa Rica , French Guiana , Nicaragua , and Panama ( Metcalf 1963a ; Duffels & van der Laan 1985 ; Boulard 1996 ; 1998 ; 2005 ; 2006 ; Martinelli & Zucchi 1997 ; Sanborn 2011a ; 2013 ; 2014 ; Sanborn & Maes 2012 ; Maes et al. 2012 ).
