Diagnosis. Symmachia estellina is sympatric with S. probetor , S. divisora and S. falcistriga ( Figs 151–153 ). Males are most similar to S. probetor , S. belti , S. championi , and S. atlantica ( Figs 13–14 ) and females are quite similar to most species of the “Probetoriformes” species group ( Figs 15–16 ). Males with head and thorax as in S. probetor ; FW (average size: 1.11 cm; 1.1–1.15 cm; n=19) moderately bulged, apex narrower than in other similar species; bulged area as 40% of the FW length; end of bulge aligned to the origin of M 2 ( Figs 13 , 60 ); FWD black, with a dark green sheen covering most of the wing, with a translucent white and creamy sickle-shaped spot between the discal cell and the costal margin ( Figs 13 , 60 ); dark green sheen absent roughly on the submedial areas from the inner margin to the discal cell and along the outer margin; HWD black, red spot along the costal margin and a dark green sheen patch near the tornus ( Fig. 13 ); abdomen color pattern as in S. probetor ; CAS of the tergites 4 and 5 as long as 1/6 to 1/7 of the tergites’ length and as wide as half the tergites’ width, projected anteriorly, CAS scales pale beige ( Figs 109–110 ); aedeagus thicker than in S. probetor and rather short; vesica with two bands of cornuti ( Figs 126 , 136 ). Females with thorax as in S. probetor ; FW (average size: 1.1 cm; 1.1–1.15 cm; n=8) moderately bulged ( Figs 15 , 70 ); FWD and FWV submarginal reddish orange band on the submarginal area along the outer margin, continuous from the costal margin, near the apex, to the inner margin at the tornus ( Figs 15–16 , 70 ); FWD mostly dark brown, with a weakly developed translucent white and creamy sickle-shaped spot between the discal cell and the costal margin ( Fig. 70 ); FWD and HWD speckled with faint whitish and reddish orange spots; HWD submarginal band reddish orange ( Fig. 15 ); FWV and HWV spots well developed ( Figs 16 , 79 ); HWV submarginal band well developed and straight and marginal band faint, not outlining ocelli ( Fig. 79 ); sterigma trapezoidal with a triangular median bulge at the ostium; ductus bursae bulged, but membranous near the ostium; bursa copulatrix rather stretched; signum pointed ( Fig. 141 ).

Distribution. Widespread in the Amazon basin, Suriname, Guyana, French Guiana and Trinidad, extending to the western areas of the Atlantic Forest, usually in low to mid-elevation, occurring from about sea level to 1100 m in the eastern slopes of the Andes and in Brazil (Rondônia, Acre, Amazonas, Pará, Ceará, Distrito Federal, Goiás, Mato Grosso, São Paulo and Paraná). It may occur in Venezuela, Bolivia, Paraguay, and northeastern Argentina and in other Brazilian states.

Comments. Symmachia estellina was described based on 38 specimens: the holotype and the allotype, caught in copula, and further 16 males and 20 females paratypes. While the holotype and the allotype are deposited at the

MNHN, the paratypes are deposited at the JYG and LCB collections, both of which include additional specimens of S. estellina and multiple species of Riodinidae from French Guiana ( Brévignon & Gallard 1998; Gallard 2008; Gallard 2017). The Jean-Yves Gallard collection (JYG) was recently acquired by the MGCL. As noted above, this species was previously considered as a variation of or misidentified with S. probetor by multiple authors, including Seitz (1913; 1917) and Brévignon & Gallard (1998). Only a decade after, Gallard (2008) realized their mistake, described S. estellina , and recognized S. astiama as a junior subjective synonym of S. probetor .

Symmachia estellina seems to be the most abundant species of the species group in the Amazon basin and the Guianas, based on the number of specimens in collections and the reports by Seitz (1917), Brévignon & Gallard (1998), and Gallard (2008; 2017). Gallard (2017) reports the species visiting flowers, and, although sympatric with S. probetor in French Guiana, both species do not occur in the exact same place of the forest. Dolibaina et al. (2012) mentioned this species competing for territory with S. probetor at 14:00 h about five meters from the ground, in a small patch of sun of a hilltop at Serra do Divisor National Park, Acre, Brazil. In 2018, the species was also observed in the morning, between 9:30–10:00 h (DRD, pers. obs.). In the relict of Atlantic Forest at the Pico Alto, Guaramiranga, Ceará, Brazil, males of S. estellina are commonly found resting on small shrubs with no more than three meters high, between 10:00–13:00 h; females are infrequent but are found at the same places and time of activity of males (DRD, pers. obs.).
