(Figs 57–68)
Diagnosis. Forewings with proximal diagonal brown band from M to 1A, and a brown submarginal band from R4+5 to Cu1b (Fig. 57). Central sclerite of hypandrium elongate, with posterior processes distally rounded, bearing two lateral, slender, pointed projections, and a small denticle distally on the inner border; side sclerites large, robust, with a rounded prominence on inner corner, outer corner extended to form a long, acuminate apophysis, and a small, obtusely concave projection between them (Fig. 61). Phallosome unique in Triplocania; mesal endophallic sclerite with two long anterior arms curved outwards and proximally dilated; the pair of posterior sclerites small, near the apices of the mesal sclerite and the external parameres (Fig. 62). Ninth sternum broadly pentagonal (Fig. 68).
Male. Color (in 80% ethanol). Body dark brown, with light areas proximally on the abdomen. Compound eyes brown; ocelli hyaline, with ochre centripetal crescents. Head pattern (Fig. 59). Antennae: scape pale brown, pedicel and flagellum cream. Maxillary palps pale brown. Thorax dark brown, with some pale brown spots on tergal lobes of meso- and metathorax. Legs with coxae dark brown, femora proximally with dark wide spot, distally with small brown spots; tibiae and tarsi pale brown. Forewing pterostigma with proximal and distal brown bands, and brown spots at vein ends. Hindwings with basal area and part of the apex pale brown. Abdomen pale cream in the first segments, with brown subcuticular spots in the posterior segments.
Morphology. As in diagnosis, plus the following: Head (Fig. 59): H/MxW: 1.57, H/D: 2.00. IO/MxW: 0.52. MxW/IO: 3.25; vertex slightly below the level of the compound eyes. Outer cusp of lacinial tips with three broad denticles. Forewings (Fig. 57): L/W: 2.47, pterostigma: lp/wp: 4.96; areola postica high, slanted posteriorly, la/ha: 1.97. Hindwings (Fig. 58): l/w: 2.85. Hypandrium (Fig. 61). Phallosome anteriorly V-shaped, with stout side struts, joined distally to the slender external parameres; two pairs of endophallic sclerites (Fig. 62). Paraprocts (Fig. 60), broad, triangular, with abundant medium sized and short setae posteriorly; sensory fields with 25–26 trichobothria on basal rosettes. Epiproct wide, straight anteriorly, broadly rounded posteriorly, setae as illustrated (Fig. 60).
Measurements. FW: 4200, HW: 2925, F: 1075, T: 1750, t1: 750, t2: 75, t3: 150, Mx4: 250, ctt1: 27, f1: 1000, f2: 950, f3: 900, f4: 750, IO: 300, D: 450, d: 337, IO/d: 0.89, PO: 0.75.
Female. Color (in 80% ethanol). As in the male. Gonapophyses and IX sternum dark brown.
Morphology. Head: H/MxW: 1.50, H/D: 2.57, IO/MxW: 0.67, MxW/IO: 2.17. Vertex slightly above the level of the compound eyes. Outer cusp of lacinial tips broad, with three broad denticles. Forewings (Fig. 63): L/W: 2.57, pterostigma: lp/wp: 4.91; areola postica: la/ha: 2.19. Hindwings (Fig. 64): l/w: 2.94. Subgenital plate (Fig. 67) setose, with sides converging to pointed apex. Gonapophyses (Fig. 68): v1 elongate, slender, acuminate; v2 +3 with a slender pointed heel; a row of six setae, including two macrosetae on v2, distal process long, sinuous and acuminate, with abundant microsetae. IX sternum (Fig. 68). Paraprocts (Fig. 66), broad, triangular, with setal field posteriorly; sensory fields with 28 trichobothria on basal rosettes. Epiproct triangular (Fig. 66), concave anteriorly, rounded posteriorly, with setae as illustrated.
Measurements. FW: 4300, HW: 2975, F: 1125, T: 1750, t1: 750, t2: 75, t3: 150, Mx4: 275, ctt1: 22, IO: 437, D: 380, d: 255, IO/d: 1.72, PO: 0.67.
