( Fig. 5 )

TYPE MATERIAL. Holotype. “ ECUADOR: Coñar Prov. / Herrera Ranch 40-70m / Sona Cochancay. 1979 // LACM ENT 403517 ” male ( LACM) . Paratype. “Peru / S. Amer. / 8-1970” female ( UMSP) .

ETYMOLOGY. The name is a combination of spilo - (Gr., spilos, spot, fleck, speck, stain, blemish) and - notophora (Gr., notophoros, carrying on the back) in reference to the various piceous markings on the dorsal surface.

DESCRIPTION. Ground color of head and thorax testaceous marked with piceous and tawny, abdomen greenish testaceous marked with piceous. The pronotal collar is bright green in the holotype. Ochraceous may be green in fresh specimens as the pronotal collar is greenish testaceous in the paratype.

Head.

MEASUREMENTS (MM). N = one male or one female. Length of body: male 30.90, female 30.70; length of fore wing: male 44.35, female 45.25; width of fore wing: male 13.85, female 14.15; length of head: male 5.55, female 5.40; width of head including eyes: male 14.10, female 14.20; width of pronotum including suprahumeral plates: male 14.65, female 15.00; width of mesonotum: male 12.45, female 12.65.

DIAGNOSIS. The most similar species in general appearance is G. chlorogena ( Walker, 1850) . The new species can be distinguished by the fore wing infuscation on the radial and radiomedial crossveins, the cubitus anterior vein is straight in the new species rather than arching, the white rather than green basal membranes of the wings, the piceous markings on either side of the pronotal midline, the dorsal pronotal collar being as wide as rather than narrower than the lateral pronotal collar, the piceous markings in the submedian sigillae do not extend the length of the parapsidal suture, and the piceous markings on the anterior abdominal tergites do not cross the midline in the new species. The only other known species of Guyalna to have infuscation on the radial and radiomedial crossveins are G. bonaerensis ( Berg, 1879) and G. flavipronotum ( Sanborn, 2007a) . Both species can be distinguished quickly by the infuscation on the distal wing veins between apical cells and along the ambient vein in these species that is absent in the new species. Two other large species, G. fumea and G. jamesi Sanborn 2016b , are dark bodies, have bronzing in the distal wings, dark basal areas of the wings, mostly or completely opaque basal cells in the fore wings, and lack the infuscation on the radial and radiomedial crossveins. The final large species of the genus, G. atalapae , can be distinguished quickly by its bright red and brown basal areas and distal bronzing of the wings.

There is a general similarity to F. pronoe of the Peruvian fauna but the new species can be distinguished by the three-part tarsi and the more semicircular female operculum, the radial crossvein intersecting the radius anterior at about half distance instead of quarter distance, wider fore wings, etc.

DISTRIBUTION. The species is currently only known from the holotype collected at an unknown locality in Peru.
