Triplocania manueli n. sp.

( Figs 72–86 )

Diagnosis. Close to T. magnifica Roesler in forewing venation and pigmentation pattern, and in phallosome structure, with a wide, shield shaped phallobase. It is the only species of Triplocania so far known, having the hypandrium of five sclerites.

Male. Color. Compound eyes black, ocelli hyaline, with ochre centripetal crescents; head pattern ( Fig. 72 ). 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, in V, 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. 73 ). 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. 74 ).

Morphology. Compound eyes without interommatidial setae. Outer cusp of lacinial tip broad, with four denticles ( Fig. 75 ). Forewing pterostigma basally narrow, wider in the middle, narrowing posteriorly; Rs convex, R2+3 and R4+5 sinuous, M concave proximally, then almost straight, M1 almost straight, M2 and M3 sinuous; areola postica with apex rounded, strongly slanted posteriorly; 2A reaching wing margin. Hindwing Rs straight, R2+3 and R4+5 straight, M sinuous. Hypandrium ( Fig. 76 ) of five sclerites, central sclerite almost straight anteriorly, posteriorly projected in the middle, setae as illustrated; side sclerites very large, wider in the middle, narrowing at the ends, acuminate, setae as illustrated; posterior pair of sclerites stout, curved outwards, anteriorly almost rectangular, strongly sclerotized distally, with a field of strong, short spines. Phallosome ( Fig. 77 ) shield shaped, side struts expanded, robust, fused, with a longitudinal pigmented band in the middle; posteriorly fused to external parameres, these stout, distally sclerotized, bearing pores; a mesal posterior endophallic sclerite, broad, pigmented throughout, except the postero-lateral corners, anterior border obtusely concave, posterior border jagged. Two pairs of endophallic sclerites, antero-mesal pair almost triangular, wider anteriorly, narrowing posteriorly, with numerous small triangular papillae near inner margin; a postero-lateral pair, of arms elongate, bow shaped, blunt at both ends. Epiproct wide, almost straight anteriorly, rounded posteriorly, with three setae in mesal position, other setae as illustrated ( Fig. 78 ). Paraprocts broadly semi-elliptic, distal setae as illustrated, sensory fields with 33 trichobothria on basal rosettes ( Fig. 78 ).

Measurements (in microns): FW: 4334, HW: 2777, F: 1077, T: 1734, t1: 747, t2: 79, t3: 131, f1: 720, f2: 552, f3: 442, Mx4: 253, IO: 472, D: 363, d: 257, IO/d: 1.83, PO: 0.71.

Female. Color. Essentially as in the male.

Morphology. Head, forewing and hindwing ( Figs 79, 80 and 81 ) same as in the male. Outer cusp of lacinial tip broad, with four denticles ( Fig. 82 ). Subgenital plate broad, posteriorly rounded; pigmented area with arms broad, V-shaped, setae as illustrated ( Fig. 83 ). Ninth sternum ( Fig. 84 ) anteriorly slightly concave, posteriorly rounded, with a U shaped pigmented band next posterior border; a mesal area, anteriorly deeply cleft in the middle, posteriorly rounded. Gonapophyses: v1 stout, wider in the middle, narrowing at the ends and distally acuminate; inner edge and the ends sclerotized; v2 +3 broad, narrowing posteriorly, with slender and curved inwards proximal heel; ten setae on outer lobe, distal process slender, distally acuminate, with a field of microsetae ( Fig. 85 ). Epiproct lost in preparation. Paraprocts almost triangular, broad, sensory fields with 30 trichobothria on basal rosettes; setae as illustrated ( Fig. 86 ).

Measurements (in microns): FW: 4549, HW: 3074, F: 1064, T: 1752, t1: 673, t2: 95, t3: 146, f1: 636, f2: 558, f3:463 Mx4: 274, IO: 551, D: 363, d: 256, IO/d: 2.15, PO: 0.71.
