Identification. Cylindrostethus palmaris   is the only South American species of the genus that displays wing dimorphism, with apterous and macropterous morphs ( Fig. 5H, J). Other species from the continent are entirely apterous, which makes identification of winged specimens immediate ( Floriano et al. 2016). Our apterous specimens were identified based on the body mostly yellow; the lateral black stripes of the mesonotum as wide as the median yellow stripe ( Fig. 5H); the black fore tibia; the posterior margin of male abdominal sternum VII emarginated at the middle ( Fig. 5I); and the basolateral processes of the male proctiger distinctly shorter than wide ( Floriano et al. 2016).

Distribution in Brazil. RR, AP, AM, PA, RO, MA, RN, BA, MT, GO, MS, MG, ES, SP, RJ.

Comments. Previously recorded in Maranhão from the municipalities of Timon and Imperatriz ( Rodrigues et al. 2012; Floriano et al. 2016).
