Triplocania manueli  n. sp.

( Figs 72–86View FIGURES 72 – 78View FIGURES 79 – 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. 72View FIGURES 72 – 78). Scape brown, pedicel yellow, f 1 –f 3 yellow. Mx 4 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 R 4 + 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. 73View FIGURES 72 – 78). 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. 74View FIGURES 72 – 78).

Morphology. Compound eyes without interommatidial setae. Outer cusp of lacinial tip broad, with four denticles ( Fig. 75View FIGURES 72 – 78). Forewing pterostigma basally narrow, wider in the middle, narrowing posteriorly; Rs convex, R 2 + 3 and R 4 + 5 sinuous, M concave proximally, then almost straight, M 1 almost straight, M 2 and M 3 sinuous; areola postica with apex rounded, strongly slanted posteriorly; 2 A reaching wing margin. Hindwing Rs straight, R 2 + 3 and R 4 + 5 straight, M sinuous. Hypandrium ( Fig. 76View FIGURES 72 – 78) 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. 77View FIGURES 72 – 78) 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. 78View FIGURES 72 – 78). Paraprocts broadly semi-elliptic, distal setae as illustrated, sensory fields with 33 trichobothria on basal rosettes ( Fig. 78View FIGURES 72 – 78).

Female. Color. Essentially as in the male.

Morphology. Head, forewing and hindwing ( Figs 79, 80 and 81View FIGURES 79 – 86) same as in the male. Outer cusp of lacinial tip broad, with four denticles ( Fig. 82View FIGURES 79 – 86). Subgenital plate broad, posteriorly rounded; pigmented area with arms broad, V-shaped, setae as illustrated ( Fig. 83View FIGURES 79 – 86). Ninth sternum ( Fig. 84View FIGURES 79 – 86) 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: v 1 stout, wider in the middle, narrowing at the ends and distally acuminate; inner edge and the ends sclerotized; v 2 + 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. 85View FIGURES 79 – 86). Epiproct lost in preparation. Paraprocts almost triangular, broad, sensory fields with 30 trichobothria on basal rosettes; setae as illustrated ( Fig. 86View FIGURES 79 – 86).
