n. sp.

Triplocania rosae  n. sp.

( Figs 110–123View FIGURES 110 – 116View FIGURES 117 – 123)

Diagnosis. Close to T. manueli  , differing from it in having the mid process of the central sclerite of the hypandrium very small; the posterior pair of sclerites are small and proximally close to the central sclerite. The external parameres of the phallosome are wider and slightly concave distally, quite distinct from those in T. manueli  .

Male. Color. Compound eyes black, ocelli hyaline, with ochre centripetal crescents; head pattern ( Fig. 110View FIGURES 110 – 116). Scape and pedicel pale yellow; f 1 –f 3 pale yellow. Femora brown; tibiae pale brown; tarsomere 1 yellow, tarsomeres 2–3 pale brown. Forewing pattern as in T. manueli  , veins brown, with dark brown spots at wing margin ( Fig. 111View FIGURES 110 – 116). Hindwing 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. 112View FIGURES 110 – 116).

Morphology. Compound eyes without interommatidial setae. Outer cusp of lacinial tip broad, with three denticles ( Fig. 113View FIGURES 110 – 116). Wings as in T. manueli  . Hypandrium ( Fig. 114View FIGURES 110 – 116) of five sclerites, central sclerite with setae as illustrated, posteriorly with a well-defined, concave area, heavily sclerotized, with a small mid projection; anteriorly almost straight, with sides close to anterior lateral sclerites, these large, wider in the middle, narrowing at the ends, acuminate, setae as illustrated: posterior pair of sclerites slender, elongate, almost fused proximally to the central sclerite, distal half with a field of small, short spines. Phallosome ( Fig. 115View FIGURES 110 – 116) shield shaped, with side struts expanded, robust, fused, with the fusing line heavily sclerotized, elongate; external parameres stout, distally sclerotized, with a mesal area not sclerotized, bearing a field of pores; a mesal posterior broad endophallic sclerite, anteriorly and posteriorly concave, with two projections on each side, slender, slightly curved inwards, posteriorly more sclerotized, with two stout projections, leaving between them a small concavity. A mesal anterior area bag shaped, with an internal area well defined, drop shaped, heavily sclerotized. Two pairs of endophallic sclerites, an antero-mesal pair, almost triangular, narrowing anteriorly, wide posteriorly, with a field of small spines; posterolateral pair elongate, heavily sclerotized, curved inwards. Epiproct wide based, posteriorly rounded; setae as illustrated ( Fig. 116View FIGURES 110 – 116). Paraprocts broad, sensory fields with 36 trichobothria on basal rosettes, setae as illustrated ( Fig. 116View FIGURES 110 – 116).

Measurements (in microns): FW: 4044, HW: 2602, F: 939, T: 1534, t 1: 646, t 2: 66, t 3: 128, f 1: 659, f 2: 493; IO: 415, D: 337, d: 239, IO/d: 1.73, PO: 0.71.

Female. Color. Same as in the male.

Morphology. Head and wings same as in the male ( Figs 117, 118 and 119View FIGURES 117 – 123). Outer cusp of lacinial tip broad, with six denticles ( Fig. 120View FIGURES 117 – 123). Subgenital plate broad, with sides converging to a pointed apex, pigmented area wide, V shaped, setae as illustrated ( Fig. 121View FIGURES 117 – 123). Ninth sternum with two distinct areas, a transverse anterior one, with anterior and posterior borders heavily sclerotized, anteriorly almost straight, posteriorly sinuous; a posterior area V shaped, with antero-lateral corners rounded, sclerotized, with a sclerotized band latero-posteriorly, and a mesal concave area ( Fig. 122View FIGURES 117 – 123). Gonapophyses: v 1 stout, wider in the middle, narrowing proximally and distally, acuminate; with outer edge more sclerotized; v 2 + 3 broad, with stout proximal heel; eight setae on outer lobe, distal process slender, distally acuminate, with a field of microsetae ( Fig. 122View FIGURES 117 – 123). Epiproct triangular, setae as illustrated ( Fig. 123View FIGURES 117 – 123). Paraprocts triangular, slightly concave proximally; sensory fields with 32 trichobothria on basal rosettes ( Fig. 123View FIGURES 117 – 123).

Measurements (in microns): FW: 4889, HW: 3163, F: 1070, T: 1768, t 1: 748, t 2: 73, t 3: 169, f 1: 636, f 2: 552, f 3: 451; IO: 515, D: 351, d: 246, IO/d: 2.09, PO: 0.7.

Material examined. Holotype Male ( INPA  ). Brazil. Paraná. Morretes. IX –X. 1984. CIIF. Malaise [trap]. Paratypes: 1 male ( INPA  ). Same data as the holotype. 2 females ( INPA  ). Same data as the holotype, except VII.–VIII. 1984.

Etymology. This species is dedicated, in memoriam, to Rosa Santana da Silva (1940–2015), mother of Alberto Moreira da Silva-Neto.
