Type data. ♂ neotype (MNRJ 2465) Brazil, Bahia, Igrapiúna, Reserva Ecológica da Michelin, 24–25.vii.2009, ARS Andrade leg.
Justification of the neotype designation. The initial cause for this long-standing taxonomic imbroglio has been Koch’s mismatching of Perty’s species. Also, Roewer not having seen Perty’s book helped conceal the true identity of F. pi c t a, which resulted in the identification of another species as such. The anchoring of the name F. picta in an actual specimen deposited in an important collection is paramount to solving the identity of the genus Flirtea and ultimately the taxonomy of this important harvestman family.

Description (Male neotype): (Figs 3–7). Measurements. Body length: 5.0. Maximum width of scutum: 4.2. Carapace length 1.9, width 2.9. Interocular distance: 0.6. Legs: I: 20.96 (0.64, 6.28, 1.16, 3.80, 6.12, 2.96), II: 41.91 (0.73, 11.82, 1.55, 9.36, 12.91, 5.55), III: 27.40 (1.00, 8.60, 1.40, 4.70, 7.70, 4.00), IV: 38.22 (1.00, 11.89, 1.78, 6.56, 11.44, 5.56).
Dorsum. Robust animal, with legs elongate but not filiform (Fig. 3 a). Dorsal scutum in dorsal view betashaped with shallow cheliceral sockets (Fig. 4 a). Dorsal scutum in lateral view convex, more so at area III, coxa IV greatly developed, thicker than scutum in lateral view (Figs 3 c, 4b). Ocularium low, narrow, with median depression (Figs 3 b, c, e, 5a). Scutal grooves poorly delimited. Scutum entirely glossy and unarmed, except for a pair of minute granules on area I and a pair of high paramedian acuminate spines with thicker base on area III (Figs 3 b, c, 4b). Free tergites I–III and anal operculum smooth and unarmed (Figs 3 c, f, 4a, b).
Venter (Figs 3 d, 5d–f). Coxae I–III triangular, transverse to main body axis. Coxae II to IV connected by tubercle bridges. Ventral elements of coxa I: e1 = ca. 12 small tubercles forming a loose row; e2 = 3 large tubercles clustered; e3 = 1 very large conical process; e4 = 1 huge bifid process; e5 = indistinct cluster of 4–5 cusps. Coxa IV pentagonal, greatly developed, oriented obliquely, but almost parallel to body axis. Stigmatic area T-shaped with stigmata large, unconcealed. Free sternites smooth and unarmed.
Chelicera (Figs 6 a–b). Neither basichelicerite nor hand thickened or swollen. Bulla short, rounded, bordered with short setiferous tubercles, 8 ectal and 7 posterior. Bulla dorso-mesal anteriorly with 2 triangular lobes.
Pedipalpus (Figs 6 c–f). Tr with stout antero-dorsal protuberance. Fe strongly compressed, concave on mesal surface, unarmed both dorsally and ventrally. Ti strongly depressed, with weakly distinct groove on mesal edge. Shape asymmetrical, with ectal side more pronounced, armed distally with a row of 6 short spines and a conical process. Corresponding mesal side with a widely spaced row of 5 short spines. Ta moderately elongate, with tight irregular ventro-ectal row of 10 short spines, a much sparser ventro-mesal row of 7 short spines and a proximal mesal cluster of 5 short spines.
Legs. Elongate and moderately thick (growing thicker from I to IV), entirely unarmed. All femora straight. Tarsal claws unpectinate. Tarsal formula: 7(3)–?/14(3)–13(3)/8–8/7–9.
Color (in alcohol). Background of body (dorsal and ventral) and appendages Deep Red (13). Pedipalps and chelicerae Strong Yellow (84) with darker mottling. Mask blots Yellowish White (92). In vivo all appendages are uniform, considerably darker (Fig. 2 c).
Genitalia (Figs 7 a–e). Ventral plate of penis rectangular and very elongate, widening slightly distally, and with distal border widest, distinct, as a transverse bar. Lateral margins of dorsal portion of VP strongly concave along their length. Four pairs of larger macrosetae inserted on lateral margin of VP: Two pairs C1–C2 greatly developed, curved and flattened, the third pair of macrosetae, adjacent to C1-C2, robust, cylindrical and straight, is best interpreted as D1, while D2 is much reduced and located proximally. The fourth pair of MS, here interpreted as A1, is extremely similar in shape to D1 and also pointing basally. A pair of small microsetae B is located ventro-basally on VP, while E1–E2 also reduced are located more ventrally and distally to D2. Microsetae almost entirely absent, but for a small ventrodistal patch. Stylus strongly curved, flattened, with apical depression flanked by a short wattle. Ventral process of glans flat, thumb-shaped.
Variation of the scaramuccia mask (Figs 8 a–l). We have not found any specimen with a complete mask as in the hypothetic reconstruction in Fig. 2 a. There are always dissociated elements and the progression of this dissociation is not linear. Element ae (arborescent ears) is quite constant in all specimens examined, mostly welldeveloped (Figs 8 a–e), always punctured by the minor ocellar fenestrae (mo). In some specimens ae are reduced and mo are few and large (Fig. 8 i). Element cp (cheek projection) is almost always reduced, in many specimens only the distal part remains, severed from the main body of the mask (Figs 8 a, 8k), sometimes entirely lacking (Figs 8 g–j). An example of an entire cp is Fig 8 f. Anterior ribs (elements r1 and r2) are mostly lacking altogether. Often there are small blots, which are remnants of the complete rib. Also their stubs sometimes are seen along the backbone (bb). Element r3 is most often reduced, with short branches (as in Perty’s specimen) sometimes there are only two round blots marking its extremity, sometimes the dissociation is such that even some of bb is also lost (Fig. 8 l). The main ocellar fenestrae (element oc) are typically very small (including Perty’s specimen, and see the other extreme in Fig. 8 d), but correlated with this dissociation, the “eyes” of the mask are wide open (Figs 8 f–l). Two pairs of satellite blots (s1–s2) are always present.
Female. Very similar to male, differing only by coxa IV being entirely hidden under dorsal scutum in dorsal view and by basitarsomeres of leg I not thickened.
