(Figs 84–89)

Paratypes: 1 male, as holotype except for 03– 24.x.2003; 1 male, as holotype except for emergence trap on Nidularium innocentii (212), 09.i–10.ii.2004. 1 male, São Paulo: Peruíbe, Estação Ecológica Juréia, Itatins, 24°31'06''S 47°12'06''W, 3.v.2002, Malaise trap (Bosque-7), N.W. Perioto et al. (BIOTA-FAPESP); 2 males, Ubatuba, Parque Estação Serra do Mar, 23°21'43''S 44°59'22''W, 24.i.2002, Malaise trap (Trilha-4), N.W. Perioto et al. (BIOTA-FAPESP); 1 male, as previous except for Malaise trap (Trilha-5); 1 male, as previous except for 21.i.2002, Malaise trap (Trilha-1); 1 male, as previous except for 21.i.2002, Malaise trap (Bosque-9). 2 males, Rio de Janeiro: Nova Iguaçu, Reserva Biológica Tinguá, 22°34'30''S 43°26'07''W, 5–8.iii.2002, Malaise trap (Trilha-4), S.T.P. Amarante et al. (BIOTA-FAPESP); 1 male, as previous except for 22°34'28''S 43°26'09''W, 8–11.iii.2002, Malaise trap (Trilha-5) (MZUSP; ZMBN; ZSM).   
 Diagnostic characters: The species can be separated from the two other members of the genus by the presence of spines on third palpomere, the shape of the lateral lamellae of the virga, and by having setae on R, R 1 and R 4+5 and in cells r 4+5, m 1+2 and m 2+3.   
 Etymology: Floripa is slang for Florianópolis City, the type locality of the species; the name is to be regarded as a noun in apposition.

 Head. AR 1.04–1.48, 1.27. Ultimate flagellomere 360–475, 417 µm long. Temporal setae 9–13, 10; including 3–5, 4 inner verticals; 2–6, 4 outer verticals; and 2–4, 3 postorbitals. Clypeus with 6–11, 8 setae. Tentorium, stipes, and cibarial pump as in Figure 84. Tentorium 95–120, 109 µm long; 18–29, 23 µm wide. Stipes 109–136, 122 µm long. Palp (Fig. 85) segment lengths (in µm): 16–27, 21; 32–45, 39; 100–136, 112; 82–111, 97; 102–123, 114 (6). Third palpomere with 2–4, 3 sensilla clavata subapically, longest 9–16, 12 µm long; with 1–3, 2 apical spines, 23–34, 29 µm long.   
 Thorax (Fig. 86). Antepronotum with 2–5, 4 setae. Dorsocentrals 8–16, 12; acrostichals 19–21, composed of 3–4, 4 anterior strong decumbent, 3–6, 5 weak simple, and 9–19, 12 posterior scalpellate; prealars 4–7, 5; 1 supraalar. Scutellum with 10–14, 11 setae, uniserial to biserial.   
 Wing (Fig. 87). VR 1.27–1.37, 1.33. C extension 32–75, 53 µm long. Brachiolum with 1 seta; costal extension with 4–8, 5 non-marginal setae; R with 7–18, 9 setae; R 1 with 6–12, 8 setae; R 4+5 with 8–14, 9 setae; M with 0–1, 0 seta; M 1+2 with 23–38, 30 setae; cell r 4+5 with 83–148, 109 (7) setae; m with 43–76, 59 setae; m 3+4 with 3–21, 13 setae.

 1+2   
 Legs. Spur of foretibia 45–61, 53 µm long; spurs of midtibia 25–41, 30 (8) µm and 23–32, 26 (9) µm long; spurs of hind tibia 43–57, 50 µm and 18–29, 23 µm long. Width at apex of foretibia 29–36, 33 µm; of midtibia 27–34, 31 (9) µm; of hind tibia 37–45, 41 µm. Comb with 11–14, 13 setae; longest 34–48, 41 µm; shortest 16–27, 22 µm long. Lengths and proportions of legs as in Table 14.

 Remarks: The occurrence of palp elongation and strong spines on third palp segment were reviewed by Ferrington and Saether (1995) and considered to be a homoplastic character among Orthocladiinae.   
 Biology and distribution: The males were collected in Malaise traps, except for one specimen which was taken in an emergence trap set on a bromeliad. This species is known from the Atlantic Rainforest from Santa Catarina north up to Rio de Janeiro State in Brazil.
