Triplocania dimitrii n. sp.

( Figs 116–127 )

Diagnosis. Forewings hyaline; central sclerite of hypandrium densely setose, deeply concave posteriorly; with elongate and slender lateral posterior processes, and with two median, short processes; phallosome Y-shaped anteriorly, with stout stem; anterior endophallic sclerites stout, U-shaped, mesal sclerite broadly U-shaped, with a median, short, pointed posterior process and long side arms distally acuminate, slightly curved outwards, each bearing a stout, mesal, pointed process on outer border; posterior sclerites boomerang-shaped, stout, with small denticles along the inner border ( Fig. 121 ). IX sternum with transverse area anteriorly, rounded on sides, with two irregular pigmented areas on posterior border; a large, posterior membranous area, with a small, distinct rounded area, surrounded with creases mesally on each side ( Fig. 127 ).

Male. Color (in 80% ethanol). Body brown, with creamy areas, as indicated below. Head pale brown, with dark brown areas as illustrated ( Fig. 118 ); labrum brown. Compound eyes ochre, ocelli hyaline, with ochre centripetal crescents. Antennae pale brown, scape brown, flagellomeres with apices cream. Maxillary palps pale brown. Prothorax cream. Tergal lobes of meso- and metathorax pale brown. Thoracic meso- and meta-pleura cream, with brown spots. Legs pale brown, mid- and hind- coxae creamy, with small proximal and distal pale brown spots. Wings hyaline, veins brown, with brown spots at wing margin ( Figs 116-117 ). Abdomen pale cream, with subcuticular, ochre transverse bands on segments I–V. Clunium and hypandrium brown, central sclerite of hypandrium pale brown, with the latero-posterior processes yellowish. Epiproct and paraprocts pale brown, phallosome brown, with endophallic sclerite more pigmented.

Hypandrium ( Fig. 119 ). Phallosome ( Fig. 121 ), external parameres distally rounded, bearing pores distally. Paraprocts ( Fig. 120 ) robust, elongate, with macrosetae and medium sized setae posteriorly; sensory fields with 36 trichobothria on basal rosettes. Epiproct semioval, posteriorly rounded, convex anteriorly, with setae as illustrated ( Fig. 120 ).

Female. Color. As in the male. Subgenital plate with deep, hyaline median concavity, pigmented area dark brown, posteriorly pale brown ( Fig. 125 ). IX sternum yellowish, with anterior area delimited by brown oval ring; gonapophyses brown ( Fig. 127 ).

Morphology. As in diagnosis, plus the following: Head ( Fig. 124 ): H/MxW: 1.43, H/d: 2.83; IO/MxW: 0.75. MxW/IO: 1.94. Vertex as in the male. Outer cusp of lacinial tips broad, with six denticles. Forewings ( Fig. 122 ) as in the male, L/W: 2.52, pterostigma: lp/wp: 6.21; areola postica, al/ah: 1.68. Hindwings ( Fig. 123 ): l/w: 2.87. Subgenital plate ( Fig. 125 ) broad, setose, triangular. Gonapophyses ( Fig. 127 ): v1 slender, elongate, acuminate; v2 +3 wide proximally, with slender heel; a row of nine macrosetae on v2; distal process sinuous, acuminate, with field of microsetae. Paraprocts ( Fig. 126 ) triangular, with setae as illustrated; sensory fields with 32 trichobothria on basal rosettes. Epiproct ( Fig. 126 ) triangular, with apex rounded, mesal field with three macrosetae, two lateral, and setae along sides and apex, as illustrated.
