Remarks. This new species is considered to be the undetermined new species of Dorisiana discussed by Wolda (1989) & Wolda & Ramos (1992). The type series was collected at one of the localities mentioned in these works and is the only unidentifiable species of a Dorisiana -like species that I found in collections. In addition, the image described in the previous paragraph that matches the females in the type series is evidence to support the synonymy of the new species identified in Wolda (1989) & Wolda & Ramos (1992) with this new species. The genus Guyalna did not exist when the species was discussed by Wolda (1989) or Wolda & Ramos (1992). Dorisiana is structurally similar to Guyalna and many species have been classified in either genera at one time or another (Sanborn 2016a). The lobate timbal covers classify this new species in the genus Guyalna rather than Dorisiana (Sanborn 2016a). The species is a rainy season cicada with emergences between late April to early November (Wolda 1989). The species sang during the day in Panama (Wolda 1993).
Etymology. The name is in honor of Henk Wolda who referenced the new species and provided ecological data on multiple Panamanian cicada species.

Measurements (mm). N = 2 males or 9 females, mean (range). Length of body: males 22.15 (21.5–22.8), females 19.46 (18.1–20.4); length of fore wing: males 32.60 (32.4–32.8), females 29.56 (28.1–31.0); width of fore wing: males 9.85 (9.8–9.9), females 9.39 (8.9–10.0); length of head: males 3.60 (3.5–3.7), females 3.33 (2.8–3.6); width of head including eyes: males 9.45 (9.3–9.6), females 8.72 (8.1–9.2); width of pronotum including suprahumeral plates: males 9.35 (9.3–9.4), females 8.54 (7.8–9.3); width of mesonotum: males 8.00 (7.8–8.2), females 7.39 (6.9–7.8).
Diagnosis. The new species can be distinguished easily from the other Panamanian species of Guyalna. Guyalna bicolor is a short, stocky species being about half as wide as long with a green (fading to ochraceous in some specimens) head and thorax and castaneous or testaceous abdomen and G. bogotana is greenish tawny head and thorax with an ochraceous abdomen rather than the dark brown and piceous new species. In addition, the abdominal tergites of male G. bogotana are translucent. The much larger (body length 35 mm) G. fumea has infuscation on the distal half of the fore wings and distal hind wings easily distinguish this species. The most similar Panamanian species is G. panamensis but it can be distinguished by its tawny body (greenish tawny in fresh specimens), the mesothorax only marked with piceous along the parapsidal suture, the abdomen has silvery and piceous pile that produce a piceous arch across the dorsal tergites from tergites 3–7 and the males and females are of similar size in G. panamensis.
The new species can be distinguished from the remaining species of Guyalna relatively easily as well. The new species has a body length (18-23 mm) less than G. aurora Ruschel, 2017, G. bonaerensis (Berg, 1879), G. brisa (Walker, 1850), G. chlorogena (Walker, 1850), G. flavipronotum (Sanborn, 2007b), G. fumea (Distant, 1883), G. jamesi Sanborn, 2016b, G. principes Ruschel, 2017, G. rufapicalis Boulard, 1998, G. sakakibari Ruschel, 2017 and G. spinula Ruschel, 2017 all of which have body lengths greater than 25 mm. The smaller body size (19 mm or less) of G. cuta (Walker, 1850), G. nadae Gogala, Šporar, Sanborn & Maccagnan, 2015, G. nigra Boulard, 1999, G. parvula (Jacobi, 1904), G. platyrhina Sanborn & Heath, 2014 and G. sublaqueata (Uhler, 1903) distinguish them from the new species. The new species can be distinguished from G. atalapae Boulard & Martinelli, 2011 by the orange basal area and smoky distal edge of its fore wing, from G. bleuzeni Boulard & Martinelli, 2011, G. coffea Sanborn, Moore & Young, 2008 and G. distanti (Goding, 1925) where the mesothorax is marked only along the parapsidal suture with piceous, from G. densusa Boulard & Martinelli, 2011 and G. jauffreti Boulard & Martinelli, 1996 by the ochraceous ventral surfaces of these species, from G. flavantica Ruschel, 2017, G. maxineae Sanborn, 2016b and G. tenebrae Ruschel, 2017 by the infuscation at the base of the hind wing extending about a third of hind wing length and the basal cell of the fore wing is colored completely, from G. pilosa Ruschel, 2017 by the infuscation at the base of the hind wing extending about a third of hind wing length, the basal cell of the fore wing is colored completely and the dense pile possessed by this species. Finally, G. glauca (Goding, 1925) has a monochromatic green head and thorax without piceous markings.
Distribution. The type series was collected in Darién Province, on Barro Colorado Island and at Curiche, Choco, Colombia. Curiche is less than 30 km south of the Panamanian border on the west coast of Colombia. The species was reported from Barro Colorado Island, Panama Canal Zone, 120 m altitude in lowland forest (Wolda 1989; Wolda & Ramos 1992) and from Las Cumbres, 15 km north of Panama City in Panama (Wolda 1993) as an undetermined species.
