Triplocania umbrataoides sp. nov.

Triplocania umbrata García Aldrete, 1999: 164-165 : male-female association by error). ( Figs. 27-41 ).

Diagnosis: Forewing veins R₂₊₃ to Cu1a with a brown spot at wing margin, from M1 to anterior end of wing, the vein spots connected to form a slender marginal band; other brown areas as illustrated ( Figs. 28-29 ); setae of the forewing veins arising from brown areolae; vein Rs notably longer than R₂₊₃, R₄₊₅ and M stem, this concave before its first bifurcation. Hypandrium with a large central sclerite, anteriorly convex, with mesal processes directed outwards; posterior process stout; distally cleft in the middle, with projections directed outwards. Phallosome with side struts fused posteriorly to external parameres. Ninth sternum broad, anteriorly with two blunt projections, leaving between them a membranous concave area; a mesal transverse sclerotized band in the middle; two almost elliptic areas, well defined, near posterior border, with a pigmented band, almost rectangular between them.

Male: Color: Compound eyes black, ocelli hyaline, with ochre centripetal crescents; head pattern ( Fig. 27 ). Scape and pedicel yellow. Femora pale yellow; tibiae pale yellow with distal ends yellow; tarsomeres 1-3 yellow. Forewings ( Figs. 28-29 ); pterostigma almost entirely pigmented, with a central hyaline area; veins. Hindwing almost hyaline, with brown spots distally on R₂₊₃, R₄₊₅ and M; veins brown.

Morphology: Compound eyes without interommatidial setae. Outer cusp of lacinial tip broad, with three denticles ( Fig. 31 ). Forewing pterostigma almost triangular, narrow basally; Rs sinuous, R₂₊₃ slightly convex, R₄₊₅ straight, M concave, M₁ slightly convex, M₂ and M₃ straight; areola postica tall, with round apex, 2A not reaching wing margin ( Fig. 28 ); right forewing anomalous, having an additional crossvein from the proximal end of Rs to R₁ ( Fig. 29 ). Hindwing Rs almost straight, R₂₊₃ straight, R₄₊₅ almost straight, M sinuous ( Fig. 30 ). Hypandrium of three sclerites; central sclerite flanked anteriorly by stout, irregular side sclerites; setae as illustrated ( Fig. 32 ). Phallosome ( Fig. 33 ) with side struts independent, V-shaped, with a strong narrowing in its connection to external parameres, these basally wide, distally rounded, bearing pores; three pairs of endophallic sclerites, anterior pair with arms L-shaped, close to each other, distally narrowing to end; mesal pair with arms Y-shaped, proximal arms with small protuberances; distal arms bow-shaped, ending in a rounded, hyaline area; median arms curved, slender, directed posteriorly, acuminate; posterior pair proximally wide, membranous, distally sclerotized, curved inwards. Epiproct wide basally, with sides converging to rounded posterior border, three setae mesally, other setae as illustrated ( Fig. 34 ). Paraprocts broad, rounded; sensory fields with 27 trichobothria on basal rosettes, setae as illustrated ( Fig. 34 ).

Measurements (in microns): FW:3079,HW:2142,F: 774, IO: 388, D: 311, d: 184, IO/d: 1.24, PO: 0.66.

Female: Color: Essentially as in the male.

Morphology: Head as in the male ( Fig. 35 ). Outer cusp of lacinial tip broad, with three denticles ( Fig. 38 ). Fore- and hind- wings ( Figs. 36, 37 ) as in the male. Subgenital plate broad, pigmented area widely concave, setae as illustrated ( Fig. 39 ); Ninth sternum ( Fig. 40 ). Gonapophyses: v1 long, slender, heavily sclerotized; v₂₊₃ stout, wider in the middle, with anterior margin almost straight, posterior margin concave, with three setae on v2, distal process slender, acuminate, basally with a field of microsetae (Fig. 79). Epiproct triangular, setae as illustrated ( Fig. 41 ). Paraprocts broadly triangular, sensory fields with 32 trichobothria on basal rosettes, setae as illustrated ( Fig. 41 ).

Measurements (in microns): FW: 3332, HW: 2366, F: 1040, IO: 410, D: 330, d: 198, IO/d: 2.07, PO: 0.6.

Etymology: The specific name refers to the similarity of this species to T.umbrata .

Material examined: Holotype male: Peru. Madre de Dios. Río Tambopata Reserved Zone. 30 km (air) SW Puerto Maldonado, 290 m. 12°50’S, 69°20’W. 14.IX.1984. Smithsonian Institution Canopy Fogging Project. T.L. Erwin et al. (INPA). Paratype: 1 female, same data as the holotype, except for date, 10.IX.1984. (INPA).

Comments: This species was erroneously identified by García Aldrete (1999) as T. umbrata ; it has a similar pattern of pigmentation and wing venation as T. umbrata , but the ninth sternum is different (compare Fig. 40 in this paper with fig. 21 in New (1980). The phallosome of T. umbrataoides is similar to other six Triplocania species ( T. lucida Roesler , T. calori Silva-Neto, García Aldrete & Rafael , T. capixaba Silva-Neto, García Aldrete & Rafael , T. ecuatoriana Silva-Neto, García Aldrete & Rafael , T. ecuatorianaoides Silva-Neto, García Aldrete & Rafael , and T.asisensis González,Carrejo & García Aldrete ). Triplocania umbrataoides differs from all the other species with similar phallosomes in details of the hypandrium and phallosome (compare Figs. 71, 72 in this paper with figs. 5, 6, 20, 21, 34, 35, 41, 42 in Silva-Neto et al. (2016c),figs. 36, 37 in Roesler (1940) and figs. 42, 43 in González-Obando et al. (2017)).
