TYPE LOCALITY. Brazil.

REMARKS. The holotype male of Cicada signifera is in the Germar collection housed at the ZMD (specimen number 1259) (http://zoomus.lviv.ua/en/germar_collection/; Shydlovskyy & Holovachov 2005) and the holotype of Cicada macropthalama is in the Stål collection at the NHRS. The holotype of Cicada macropthalama is reported to have a body length of 20 mm ( Stål, 1854). The virtual image is useful in distinguishing the species from the remaining species of the genus.

Selymbria ahyetios , S. pandora and S. subolivacea can be distinguished from this species by the lack of infuscation on the apex of the fore wing. The infuscation of the fore wing is found only on the fore wing apex in S. chevauxensis n. sp., S. cinctifera n. sp., S. guatemalensis n. sp., S. guianensis n. sp., and S. pluvialis . The piceous region on dorsal head is reduced between the lateral ocelli and eye and the medial margin to notch in female sternite VII curves laterad toward the posterior in S. puntarenasensis n. sp. The infuscation is restricted to the radiomedial crossvein in the fore wing of S. danieleae without extending onto the basal apical cells 1–3. Tergite 3 in the male is wider than tergite 2, and the medial margin of the notch in female sternite VII curves posterolaterad and distinguishes S. stigmata from S. boliviaensis n. sp., S. ecuadorensis n. sp., S. iguazuensis n. sp., S. loretoensis n. sp., and S. madredediosensis n. sp.

DISTRIBUTION. The species is currently known only from Brazil ( Metcalf 1963; Sanborn 2013). References to Panama were shown to be erroneous ( Sanborn 2018).
