Triplocania capixaba  n. sp.

( Figs 16–29View FIGURES 16 – 22View FIGURES 23 – 29)

Diagnosis. Belonging in the same species assemblage indicated above. Close to T. calori  described above, from which it differs by having the central sclerite of the hypandrium wide proximally, narrowing distally and distinctly bilobed.

Male. Color. Compound eyes black, ocelli hyaline, with ochre centripetal crescents; head pattern ( Fig. 16View FIGURES 16 – 22). Scape and pedicel pale brown, f 1 –f 4 pale brown, with apex white. Mx 4 pale brown. Femora pale yellow; tibiae pale brown; tarsomeres 1–3 yellow. Forewing with a pale brown marginal band from R 4 + 5 to CuP, with a whitish area almost circular in the connection between CuA and areola postica; a brown spot at confluence of CuP- 1 A and a pale brown area on proximal end of wing; pterostigma with brown bands anteriorly and posteriorly; veins brown, with brown spots at wing margin ( Fig. 17View FIGURES 16 – 22). Hindwing with proximal third pale brown, veins brown ( Fig. 18View FIGURES 16 – 22).

Morphology. Head vertex concave in the middle; compound eyes without interommatidial setae. Outer cusp of lacinial tip broad, with four denticles ( Fig. 19View FIGURES 16 – 22). Forewing pterostigma wider in the middle, narrow basally; Rs almost straight, R 2 + 3 almost straight, R 4 + 5 sinuous, M stem slightly concave proximally, then almost straight, M 1 and M 3 almost straight, M 2 sinuous; areola postica wide basally, slightly slanted posteriorly, 2 A not reaching wing margin. Hindwing Rs straight, R 2 + 3 and R 4 + 5 straight, M sinuous. Hypandrium of three sclerites, a large central one, wide based, convex anteriorly, with antero-lateral corners projected, directed outwards; posterior process distally bilobed, each lobe bearing two setae; flanked by large, irregular sclerites; setae as illustrated ( Fig. 20View FIGURES 16 – 22). Phallosome ( Fig. 21View FIGURES 16 – 22) with side struts independent, V shaped, with a strong narrowing in its connection to external parameres, these stout, concave in the inner margin with pores posteriorly; three pairs of endophallic sclerites, posterior pair basally wide, almost triangular, narrowing in the middle and widening posteriorly, curved inwards, ending in seven acuminate dactyloid processes; mesal pair U shaped, with inner arms elongate, curved out; outer arms basally wide, narrowing distally, acuminate; anterior pair small, heavily sclerotized, curved, proximally wide, distally acuminate, the two arms almost touching in the middle. Epiproct wide basally, with sides converging to a blunt posterior border, a small, strongly sclerotized semi-elliptic process area next to posterior border; setae as illustrated ( Fig. 22View FIGURES 16 – 22). Paraprocts broad, sensory fields with 28 trichobothria on basal rosettes; setae as illustrated ( Fig. 22View FIGURES 16 – 22).

Measurements (in microns): FW: 3839, HW: 2744, F: 1051, T: 1617, t 1: 698, t 2: 78, t 3: 134, f 1: 704, f 2: 510, f 3: 436, f 4: 403, Mx 4: 253, IO: 494, D: 373, d: 216, IO/d: 2.28, PO: 0.58.

Female. Color. Essentially as in the male.

Morphology. Head with vertex almost straight; compound eyes without interommatidial setae ( Fig. 23View FIGURES 23 – 29). Fore- and hindwings ( Figs 24, 25View FIGURES 23 – 29) same as in the male. Outer cusp of lacinial tip broad, with four denticles ( Fig. 26View FIGURES 23 – 29). Subgenital plate broad, wider in the middle, anteriorly convex, posteriorly rounded; pigmented area wide, along sides and posterior border; setae as illustrated ( Fig. 27View FIGURES 23 – 29). Ninth sternum ( Fig. 28View FIGURES 23 – 29) anteriorly formed by two rounded areas, limited by edges strongly sclerotized, with a weakly pigmented area deeply cleft between its inner margins; a transverse, elongate sclerotized band posteriorly on each side. Gonapophyses: V 1 long, slender, heavily sclerotized; V 2 + 3 stout, wider in the middle, with pointed proximal heel; nine setae on outer lobe as illustrated, distal process slender, acuminate, with a field of microsetae ( Fig. 28View FIGURES 23 – 29). Epiproct triangular, three mesal setae near anterior border, other setae as illustrated ( Fig. 29View FIGURES 23 – 29). Paraprocts broad, slightly concave proximally, sensory fields with 30 trichobothria on basal rosettes; setae as illustrated ( Fig. 29View FIGURES 23 – 29).

Measurements (in microns): FW: 4357, HW: 3064, F: 1043, T: 1592, t 1: 727, t 2: 76, t 3: 142, f 1: 599, f 2: 483, f 3: 439, Mx 4: 266, IO: 501, D: 369, d: 225, IO/d: 2.22, PO: 0.61.

Material examined. Holotype male ( INPA  ). Brazil. Espírito Santo. Fundão. Hotel Fazenda Monte Sião. 05– 24.IX. 2014. Malaise trap. Patrik Barcelos Silva. Paratypes: 5 males and 3 females ( INPA  ), same data as the holotype.

Etymology. Capixaba  is a noun that applies to the natives of the Brazilian state of Espírito Santo. By extension, it is given to this species as a noun in apposition, and makes reference to the Brazilian state of origin of this species.
