Triplocania motilona n. sp. Female

( Figs 242–246 )

Diagnosis. Forewing with slender, brown marginal band ( Fig. 242 ); veins with a brown spot at wing margin; areola postica slanted posteriorly. IX sternum wider anteriorly, concave on the sides, anteriorly and posteriorly; a transverse pigmented band along anterior border ( Fig. 246 ).

Color (in 80% ethanol). Body pale brown. Compound eyes brown; ocelli hyaline, with ochre centripetal crescents. Head pattern ( Fig. 244 ); front with two diagonal brown stripes, from each compound eye to ocellar group, and a brown band from the middle of the lower stripe to the epistomal sulcus; genae dark brown; postclypeus with a dark brown V-shaped area; anteclypeus and labrum pale brown. Pronotum cream, meso and metanotum pale brown, tergal lobes of meso- and metathorax with brown spots; thoracic pleura with brown top half, bottom and sternum cream. Coxae and trochanters cream, femora cream, with dorsal pale brown distal spot; tibiae and tarsi brown. Forewings almost hyaline, pterostigma with proximal and distal brown bands; a pale brown marginal band from R4+5 to Cu1a, around Cu1 and distal part of cu1 ( Fig. 242 ). Abdomen cream, with subcuticular ochre spots, broader in sternum. Subgenital plate pale brown; gonapophyses pale brown. Paraprocts and epiproct pale brown.

Morphology. As in diagnosis, plus the following: Head: H/MxW: 1.63; H/D: 2.77, IO/MxW: 0.70, MxW/IO: 2.18. Vertex slightly emarginate, almost at the same level as the upper border of the compound eyes. Outer cusp of lacinial tip broad, with five denticles. Forewings ( Fig. 242 ): L/W: 2.57, pterostigma: lp/wp: 5.26, areola postica elongate: la/ha: 2.40. Subgenital plate ( Fig. 245 ) triangular, densely setose, with sides converging to a rounded apex. Gonapophyses ( Fig. 246 ): v1 elongate, slender, acuminate, curved distally; v2 +3 with sides almost parallel, and with a proximal pointed heel; a row of 12 medium-sized setae and two macrosetae on v2; distal process curved, acuminate, with microsetae. Paraprocts ( Fig. 243 ), broad, triangular, with setae as illustrated; sensory fields with 28 trichobothria on basal rosettes. Epiproct triangular ( Fig. 243 ) almost as long as wide; anterior border almost straight, widely rounded posteriorly; setae along sides and posterior border, and three mesal setae near anterior border.

Measurements. FW: 6425, F: 1587, T: 2725, t1: 1212, t2: 75, t3: 162, ctt1: 32, f1: 1125, f2:1175, f3:1125, IO: 540, D: 455, d: 300, IO/d: 1.8, PO: 0.65.

Material studied. Holotype female. COLOMBIA. Norte de Santander. Aguas Calientes, National Natural Park Tamá , 7º20’N : 72º29’W, 1970 m, IAvH, E146095. Paratype, 1 female, same data as the holotype, IAvH, E145967a ( MAH) .
