description: Frankliniella catharinensis n. sp.
(Figs 4, 5, 9, 16, 21, 24, 27, 33, 40 –42)
Female macroptera. Colour: body golden brown, head and abdomen darker (Fig. 4); fore wings brown with basal fourth slightly pale (Fig. 24), legs yellow, except external margin of fore femur; body and fore wing setae dark brown. Antennal segment I brown; II almost completely brown, shaded pale brown apically; III yellow, shaded pale brown distally; IV yellow in basal half, shaded light brown distally; V yellow in basal quarter but shaded pale brown in second quarter and brown on apical half; VI–VIII brown (Fig. 9). Structure: Head about as wide as long; compound eyes with 4 pigmented facets; three pairs of ocellar setae, pair III close to external margins of ocellar triangle; five pairs of postocular setae, pair IV longer than the others; postocular setae I absent [pair III also absent in some paratypes] (Fig. 16). Antenna 8-segmented, segments III and IV with sense cone forked, pedicel on III with a slight angulation; segment VIII distinctly longer than VII. Pronotum about 1.1 times as wide as long with irregularly spaced and sparse transverse striae; one pair each of major anteromarginal and anteroangular setae, anteroangulars twice as long as anteromarginals, one pair of major posteromarginal setae and two pairs of posteroangular setae, pair I 0.8 times as long as II (Fig. 21). Mesonotum median and posterior areas transversely sculptured, with some oblique lines; one pair of campaniform sensilla anteriorly, no setae on discal area (Fig. 27). Metanotum with two pairs of setae anteriorly; campaniform sensilla absent, longitudinal lines of sculpture laterally, almost no sculpture medially (Fig. 27). Fore wings with two complete rows of setae; first vein with 19–20 setae, second vein with 12–17 setae; clavus with 5 marginal and 1 discal setae; fringe cilia wavy. Abdominal tergites IV– VIII with paired ctenidia laterally, on IV vestigial; VIII with complete posteromarginal comb of microtrichia with triangular-based teeth (Fig. 33); IX with two pairs of campaniform sensilla and S1 pair of setae about 0,15 times as long as S2; Sternite II with one or two discal setae (Fig. 40); III with two small circular pore plates on anterior third (Fig. 41); craspeda present on sternites II–VII, but sometimes interrupted medially especially on II and VII.
Measurements (Female holotype, in microns): Body length 1880. Head, length 160, width 170; Ocelar setae III 48; post-ocular setae IV 28. Pronotum, length 163, width 185; Pronotal major setae, am 25, aa 50, pm 15, pa I 61, pa II 74. Fore wing, length 952. Tergite IX, length 94, S1 setae 127, S2 setae 152. Antennal segments I–VIII, length 25, 41, 58, 48, 43, 56, 13, 18.
Male macroptera: Similar to female (Fig. 5), sternite II of available male with 2 discal setae; sternites III–VII with broad transverse median pore plates (Fig. 42).
Measurements (Male paratype, in microns): Body length 1326. Head, length 135, width 125. Pronotum, length 132, width 155; Pronotal major setae, am 20, aa 44, pm 10, pa I 50, pa II 54. Fore wing, length 700. Antennal segments I–VIII, length 20, 34, 44, 36, 34, 50, 10, 14.
Material Examined. Holotype female. Brazil. Santa Catarina: Nova Teutônia [Seara], host unknown (name of plant illegible), 27.v.1949 (F. Plaumann) (USNM).
Paratypes: Brazil. Santa Catarina: Nova Teutônia [Seara], five females and one male from Trichilia sp., xii. 1949. (F. Plaumann) (USNM).
Comments. Females of this species have a pair of small circular pore plates (=glandular areas) on sternite III, an uncommon character in this genus and also unusual in female thripids. It is also characterized by the presence of at least one discal seta on sternite II of females (holotype with two and some paratypes with only one) and the absence of poi and sometimes poiii setae (holotype with poiii setae present). Females of seven other species of Frankliniella are known to exhibit pore plates on sternite III, all from South America. From these, bambusae is the only yellow coloured species, but it also lacks poi setae, as in catharinensis. Three of them have small head and anterior pronotal setae, and ocellar setae III barely 1.5 times longer than a hind ocellus width— magellanica, tympanona and valdiviana. In common, females of these three species have only one oval pore plate on sternite III (Figs 43–44), although magellanica can exhibit an extra small oval pore plate on sternite IV. In magellanica, the mouth cone is very enlarged, and one pair of postocular setae and sometimes metanotal campaniform sensilla are absent; in valdiviana and tympanona the mouth cone is not enlarged and all pairs of po setae are present, but the latter has no metanotal campaniform sensilla (Fig. 47). The other four species— australis, bambusae, colihue and otites— as well as catharinensis, have longer ocellar setae III and a pair of pore plates on sternite III, although otites can also have only one oval pore plate on sternite III (Borbón 2013). Although otites may have ocellar setae III about 1.6–2.3 times longer than the longitudinal diameter of a hind ocellus, these setae are longer than in the three minuta group species mentioned previously (Berzosa & Maroto 2003). Differently from catharinensis, the other three species have poi setae, lack discal setae on sternite II of females and have metanotal campaniform sensilla. The Argentinean species colihue has fore wing uniformly pale (Borbón 2013), whereas otites has brown fore wing with basal fifth sometimes slightly paler than the other four fifths and australis has basal fifth distinctively paler than the rest of the fore wing. In addition, australis have ocellar setae III longer than those in otites. Males of australis, colihue and otites have transverse pore plates on the anterior third medially on sternites III–VII, whereas males of catharinensis have broader sternal pore plates, occupying the two anterior thirds medially on sternites III– VII. Interestingly, although pore plates occur in females of various species in both intonsa and minuta groups, these are oval and single in species of the first group but lateral and paired in species of the latter. An exception is otites that can exhibit such pores in both ways, and also have ocellar setae of intermediate size between minuta and intonsa groups. For a key to these eight species see Appendix A below.
Etymology. The species is named after the gentilic name for those from Santa Catarina, state in which the specimens were collected.
