Triplocania chocoensis n. sp. Male

( Figs 110–115 )

Diagnosis. Wings hyaline. Central sclerite of the hypandrium strongly convex anteriorly, with two median, small posterior processes, leaving between them a rounded concavity, with a pigmented band along the border ( Fig. 114 ). Phallosome V-shaped anteriorly, with side struts joined posteriorly to broad, membranous external parameres, distally rounded, bearing a field of short spines along posterior border. Anterior endophallic sclerites M-shaped, with stout arms; mesal sclerite broadly H-shaped, underlaid by elliptic rounded bands; posterior sclerites slender, curved outwards, bearing denticles on distal inner border ( Fig.115 ).

Color (in 80% ethanol). Body pale brown. Compound eyes ochre; ocelli hyaline, with ochre centripetal crescents. Head pattern ( Fig. 112 ); front with two transverse brown bands from the inner border of the compound eyes to the ocellar group, the upper one broader; two irregular brown areas above the epistomal sulcus, next to each antennal fossae; postclypeus with a V-shaped brown area; genae brown, postgenae and antennae pale brown; maxillary palps pale brown, Mx4 distally dark brown. Thorax pale brown, with areas on the tergal lobes of meso- and metathorax cream. Legs pale brown. Forewing pterostigma with pale brown bands proximally and distally. Vein ends of fore- and hind- wings with a small brown spot. Abdomen cream, with small brown spots on tergites.

Morphology. As in diagnosis, plus the following: Head ( Fig. 112 ): H/MxW: 1.52; H/D: 2.11, IO/MxW: 0.45, MxW/IO: 3.53. Vertex slightly emarginate, slightly below the level of the compound eyes. Outer cusp of lacinial tip broad, with three broad denticles. Mx4/Mx2: 1.40. Forewings ( Fig. 110 ): L/W: 2.61; pterostigma: lp/wp: 5.00; areola postica triangular, slanted posteriorly, la/ha: 2.17. Hindwings ( Fig. 111 ): l/w: 2.94. Hypandrium ( Fig. 114 ), setae as illustrated; two macrosetae on the inner margin of each of the posterior lobes of the sclerite. Phallosome ( Fig. 115 ). Paraprocts broad, oval ( Fig. 113 ), with abundant setae in the posterior third, with a macrosetae near the sensory fields; these with 22 trichobothria on basal rosettes. Epiproct wide, semioval, setae as illustrated ( Fig. 113 ).
