Antennae 8-segmented; III–IV with sensorium forked; segment VIII almost twice as long as VII. Pronotum with 5 pairs of major setae; anteromarginal setae almost as long as anteroangulars; one pair of minor setae present medially between posteromarginal submedian setae. Metanotum with 2 pairs of setae at anterior margin; campaniform sensilla present. Fore wing with 2 complete rows of veinal setae. Abdominal tergites V–VIII with paired ctenidia, anterolateral to spiracle on VIII; posteromarginal comb on VIII with long, regular, microtrichia. Sternites III–VII without discal setae, except sternite II with one or two long discal setae medially.

Male smaller than female; tergite VIII with complete comb; sternite II with one or two discal setae medially, III–VII with small oval pore plate, sternite VII with toothed craspedum on posterior margin.

Related and similar species

F. gossypiana is similar in color and structure to F. williamsi, the common species on Zea mays, but has a more slender head, and the setae on the ninth abdominal tergite are shorter. Keys to 74 species of Frankliniella recorded from Central America and the Carribean were provided by Mound & Marullo (1996), and to 40 species from Brazil by Cavalleri & Mound (2012).
