Diagnosis: Forewing with a U-shaped band from apex of the areola postica to anterior and posterior ends of pterostigma, forewing M abruptly concave before its first bifurcation,areola postica sinuous with a concavity in the middle; hypandrium of three sclerites, with central sclerite straight anteriorly, posteriorly with one short, almost triangular projection on each antero-lateral extreme, with a long, slender, blunt projection in the middle, setae as illustrated; side struts proximally expanded in shield shape and v1 stout and wider in the middle.

Redescription of the male

Color: Compound eyes black, ocelli hyaline, with ochre centripetal crescents; head pattern ( Fig. 1 ). Scape brown, pedicel yellow, f1-f3 yellow. Mx4 yellow with distal end brown.Femora brown with distal ends yellow; tibiae pale brown; tarsomere 1 pale yellow and tarsomeres 2-3 pale brown. Forewing with a brown marginal band from R₄₊₅ to areola postica, from it arise two brown arms, to anterior and distal ends of pterostigma, U-shaped, leaving a hyaline area between them; a large dark brown area on proximal end of wing; veins brown, with dark brown spots at wing margin ( Fig. 2 ). Hindwings almost hyaline, with area limited by CuP brown anteriorly and pale brown posteriorly, apex pale brown; veins brown, with dark brown spots at wing margin ( Fig. 3 ).

Morphology: Compound eyes without interommatidial setae. Outer cusp of lacinial tip broad, with three denticles ( Fig. 4 ). Forewing pterostigma basally narrow, wider in the middle, narrowing posteriorly; areola postica with apex rounded, strongly slanted posteriorly; 2A reaching wing margin ( Fig. 2 ). Hindwing R₂₊₃ and R₄₊₅ straight, M sinuous ( Fig. 3 ). Hypandrium ( Fig. 5 ) of three sclerites, central sclerite straight anteriorly, posteriorly with one short, almost triangular projection on each antero-lateral extreme, with a long, slender, blunt projection in the middle, setae as illustrated; side sclerites very large, wider in the middle, narrowing at the ends, acuminate, setae as illustrated. Phallosome ( Fig. 6 ) shield shaped, side struts expanded, robust, fused, with a small longitudinal pigmented band in the middle, posteriorly fused to external parameres, these stout, distally sclerotized, bearing pores included in a less sclerotized area; a mesal endophallic sclerite, U-shaped, wide at base and narrowing posteriorly; two pairs of endophallic sclerites, a small mesal posterior pair, elliptical, surrounded by a distinct membranous area, a posterior lateral pair anteriorly narrow, widening posteriorly with rounded apex and a pre-apical acuminate projection in its inner margin; other membranous areas as illustrated. Epiproct wide, almost straight anteriorly, rounded posteriorly, with three setae mesally, other setae as illustrated ( Fig. 7 ). Paraprocts broad, narrow at their point of attachment to the clunium, widening posteriorly, with setae in a less sclerotized posterior area, sensory fields with 34 trichobothria on basal rosettes ( Fig. 7 ).

Redescription of the female

Color: Essentially as in the male.

Morphology: Head and wings same as in the male ( Figs. 8, 9 and 10 ). Outer cusp of lacinial tip broad, with two denticles ( Fig. 11 ). Subgenital plate broad, anteriorly almost rectangular, with sides converging to apex, pigmented area wide, V-shaped, setae as illustrated ( Fig. 12 ). Ninth sternum almost rectangular ( Fig. 13 ) anteriorly with a pigmented band concave in the middle, posteriorly with a pigmented band convex near the posterior margin, with a distinct weak sclerotized central area. Gonapophyses: v1 stout, anteriorly heavily sclerotized, wider in the middle, narrowing at the ends and distally acuminate; v₂₊₃ broad, narrowing posteriorly, with slender and curved inwards proximal heel; ten setae on outer lobe, distal process slender, short, distally acuminate, with a field of microsetae ( Fig. 13 ). Epiproct triangular, with three setae mesally, other setae as illustrated ( Fig. 14 ). Paraprocts almost triangular; sensory fields with 27 trichobothria on basal rosettes ( Fig. 14 ).

Measurements (in microns): FW: 4963, HW: 3400, F: 1085, T: 1913, t1: 780, t2: 82, t3: 138, f1: 785, f2: 639, Mx4: 321, IO: 561, D: 362, d: 201, PO: 0.55.

Comments: T. magnifica , T. manueli Silva-Neto, García Aldrete & Rafael and T. rosae Silva-Neto, García Aldrete & Rafael constitute an assemblage of related species. This assemblage is characterized by having a U-shaped band from the apex of the areola postica to the anterior and posterior ends of pterostigma, forewing M abruptly concave before its first bifurcation, side struts proximally expanded in shield shape and v1 stout and wider in the middle. Triplocania magnifica is easily separated from the other two species of this assemblage by having the hypandrium of three sclerites instead of five sclerites as in T. manueli and T. rosae . Roesler (1940) in the description and illustration of the hypandrium of T. magnifica omitted or did not observe the presence of the lateral sclerites (see fig. 30 in Roesler, 1940). The central sclerite of the hypandrium of the specimens of T. magnifica used here in the redescriptions is identical to the illustration in Roesler (1940) and this, besides the fact that they were collected in the type locality of the species (Nova Teutônia) prove that they belong to T. magnifica .
