description: Frankliniella juancarlosi sp. n.
(Figs 3, 7, 10, 13, 16, 19, 25, 33, 36, 39, 44)
Female macroptera. Body brown, including legs, fore tibiae and tarsus slightly paler; antennal segments I–II and V–VIII brown, segment III paler, segment IV darker than III and paler than V; fore wings entirely brown or with scarcely visible pale basal area.
Head about 0.6 times as long as wide, posterior region with few transverse lines of sculpture; ocellar setae pair III arising between hind ocelli, about 1.4 times as long as diameter of a hind ocellus, as long as distance between their pores; six pairs of postocular setae, pair IV distinctly longer than others. Antennae segment III with simple pedicel. Pronotum rectangular, about 1.5 times as wide as long, lines of sculpture scarcely visible, about 18 small discal setae, five pairs of more developed setae, two at posterior angles and the other, sub-medial setae at posterior margin setae aa about twice as long as am setae. Mesonotum with elongate transverse reticles of widely spaced sculpture lines. Metanotum with lines of sculpture forming weak reticles medially; paired campaniform sensilla present. Abdominal tergites IV–VIII with ctenidia laterally; tergite VII with craspedum of irregular very small triangular teeth, each ending in a short microtrichium; VIII with a complete posteromarginal comb of microtrichia arising from triangular bases; S1 setae on IX equal to or scarcely shorter than S2. Sternites with three pairs of short posteromarginal setae; sternite III usually with two circular pore plates placed behind antecostal ridge, about 50 microns apart.

Antennal segments length/width 18/27, 34/24, 44/24, 36/20, 30/17, 44/19, 8/6, 16/5.
Male macroptera. Smaller than female, body uniformly brown; posterior margin of abdominal tergite VIII with complete comb of microtrichia; sternites III–VII with pair of oval pore plates.

Comments. This species seems to be related to the nine other South American species listed above in which females have pore plates on sternite III. As in F. australis, F. bambusae, F. catharinensis, F. colihue and F. otites, sternite III usually has two circular pore plates, but two females of the type series have only one pore plate. Also in some other specimens an extra pair of pore plates was found on sternite IV. The pronotal discal setae pattern is similar to that of F. otites, but F. juancarlosi is remarkable in having comparatively shorter pronotal am setae and ocellar setae pair III scarcely as long as the distance between their bases. Moreover, it usually has a comb with triangular teeth bearing very short microtrichia (Fig. 34) that are absent in the other three species. Unlike bambusae and colihue this new species does not have the head projecting in front of the eyes, and was confused with F. otites by de Borbón (2013). It seems to be particularly common in Mendoza and is also present in Neuquén, living on Verbenaceae and Asteraceae host plants.
Etymology. In memory to my father, Juan Carlos de Borbón, who help me collect this new species.
