Triplocania triangularis n. sp.
( Figs 124–138 View FIGURES 124 – 130 View FIGURES 131 – 138 )
Diagnosis. Differing from the known species of Triplocania , by having the central sclerite of the hypandrium with side triangular projections and with a triangular posterior process; the phallosome has four pairs of endophallic sclerites and a mesal, stout transverse sclerite.
Male. Color. Compound eyes black, ocelli hyaline, with ochre centripetal crescents; head pattern ( Fig. 124 View FIGURES 124 – 130 ). Scape pale brown, pedicel pale yellow; f 1 –f 2 pale yellow. Femora pale yellow; tibiae pale brown with distal ends brown; tarsomere 1 pale yellow, tarsomeres 2–3 pale brown. Forewing with an irregular, submarginal pale brown band from the distal end of the pterostigma to CuA 2; a brown area almost triangular along CuA to end of CuP; a small dark brown spot at confluence of CuP- 1 A; a brown band along the areola postica; pterostigma almost pigmented throughout, with a clear area in the middle; veins brown, with brown areolae at setal insertions and with dark brown spots at wing margin ( Fig. 125 View FIGURES 124 – 130 ). Hindwing mostly hyaline, with a small pale brown area next to CuP; veins brown, with brown spots at wing margin ( Fig. 126 View FIGURES 124 – 130 ).
Morphology. Compound eyes without interommatidial setae. Outer cusp of lacinial tip broad, with five denticles ( Fig. 127 View FIGURES 124 – 130 ). Forewing pterostigma wider in the middle, narrow basally; Rs convex, R 2 + 3 and R 4 + 5 sinuous, M stem concave proximally, then almost straight, M 1, M 2 and M 3 sinuous, areola postica tall, with round apex, 2 A not reaching the wing margin. Hindwing Rs stem convex proximally, then almost straight, R 2 + 3 and R 4 + 5 straight, M sinuous. Hypandrium of three sclerites, a large central sclerite, anteriorly convex, wide in the middle, with a triangular projection on each side; a posterior triangular process in the middle; lateral sclerites large, rhomboid, with setae as illustrated ( Fig. 128 View FIGURES 124 – 130 ). Phallosome ( Fig. 129 View FIGURES 124 – 130 ) with side struts independent, V shaped, fused posteriorly to stout external parameres, each with a field of pores mesally. Transverse mesal sclerite wide, strongly sclerotized, anteriorly concave; posterior border slightly projected in the middle, concave. Five pairs of endophallic sclerites, antero-lateral pair V shaped, with inner arms shorter than outer arms, diagonal, narrowing distally; outer arms stout, proximally wide, narrowing distally, blunt ended; antero-mesal pair rattle shaped, small, narrow anteriorly, wide posteriorly, bearing a dense field of papillae; mesal pair stout, slightly cuverd inwards, basally round, distally narrow, blunt ended; postero-lateral pair stout, sinuous, elongate, proximally wide, basally broad, narrowing posteriorly, distally curved outward; posterior pair small, broadly elliptic, parallel to the posterior inner border of the external parameres, straight anteriorly, with a row of five denticles posteriorly. Epiproct wide, almost straight anteriorly, narrowing posteriorly to round apex, three setae in mesal position, other setae as illustrated ( Fig. 130 View FIGURES 124 – 130 ). Paraprocts broad, almost triangular, sensory fields with 27 trichobothria on basal rosettes, setae as illustrated ( Fig. 130 View FIGURES 124 – 130 ).

Female. Color. Same as in the male.
Morphology. Head and wings ( Figs 131, 132 and 133 View FIGURES 131 – 138 ) as in the male. Outer cusp of lacinial tip broad, with three denticles ( Fig. 134 View FIGURES 131 – 138 ). Subgenital plate broad, V shaped, pigmented area wide, setae as illustrated ( Fig. 135 View FIGURES 131 – 138 ). Ninth sternum broad, with a distinct, convex anterior area, with a deep, pigmented concavity in the middle; a mesal area almost rectangular, with two well pigmented areas in the middle, with a deep cleft between them; with a curved, pigmented longitudinal line on each side of the mid line; two distinct postero-lateral, quadrate, weakly pigmented areas ( Fig. 136 View FIGURES 131 – 138 ). Gonapophyses: v 1 long, curved, slender, acuminate, heavily sclerotized; v 2 + 3 stout, with pointed proximal heel, wide proximally, with seven setae on outer lobe and three mesal-posterior setae as illustrated, distal process slender, sinuous, acuminate, with a field of microsetae ( Fig. 137 View FIGURES 131 – 138 ). Epiproct triangular, setae as illustrated ( Fig. 138 View FIGURES 131 – 138 ). Paraprocts broadly, semi-elliptic, sensory fields with 32 trichobothria on basal rosettes, setae as illustrated ( Fig. 138 View FIGURES 131 – 138 ).
