description: Euplocania siona n. sp. Male
(Figs 12–17)
Diagnosis. Belonging in species group erwini. Due to the shape of the hypandrium and color patterns of the forewing, it is closely related to E. erwini n. sp. Unlike this species, it presents the hypandrium of a single sclerite (laterals loosely attached to central), the latero-posterior processes of hypandrium with a row of spines on its external and internal margin; phallosome with mesal pair endophallic sclerites overlapping mesally, W-shaped (Fig. 17).
Color (in mounting plate). Head (Fig. 14) pale brown, vertex with two groups of spots in fronto orbital area and a couple more below ocellar triangle. Compounds eyes dark brown. Ocelli hyaline, with pair dorsal ochre centripetal crescents, the ventral ocellus with dorsal ochre spot; postclypeal area with four rows of brown spots; labrum pale brown. Genae dark brown, with pale brown spots. Maxillary palps brown, Mx1 clearer. Legs pale brown. Forewings (Fig. 12) as in E. erwini n. sp., with pale brown spots, pterostigma with proximal and distal brown spots; a marginal brown band from R 2+3 to areola postica, with clear rounded windows between the ends of the veins and a large brown spot distally in cua and cup cells, as illustrated. Hindwing (Fig. 13) hyaline, with brown veins. Hypandrium dark brown, with posterior processes and inner edge of medial area darker. Epiproct and paraproct light brown.
Morphology: Head (Fig. 14): H/MxW: 3.52. Vertex cleft. Compound eyes large, H/D: 2.3; IO/MxW: 0.19. Outer cusp of lacinial tip broad, with five denticles. Forewings: L/W: 2.5. Pterostigma wider medially: lp/wp: 1.8. Areola postica tall, with rounded apex: al/ah: 1.4. M 4-branched, M 4 forked distally. Hindwing: l/w: 2.84. Hypandrium (Fig. 16) as in E. erwini n. sp., with deep medial incision and setose as illustrated, narrower proximally and strongly convex anteromedially, with two laminar latero-posterior processes, apically rounded, directed towards middle, each with a row of spines on its external and internal margin, apically blunt. Phallosome (Fig. 17) with side struts Yshaped, external parameres, laminar, transverse, longer than wide; anterior endophallic sclerites, longer than broad with short processes on inner margin, proximal process acute, followed by a truncated one; posteromesal sclerite bifurcated at its distal ends, with two outwardly curved acuminate processes. Epiproct (Fig. 14) triangular, anterior margin convex, with two lateral macrosetae on basal third; distally with microspiculae and setae as illustrated. Paraprocts (Fig. 14) ovoid, with row of setae on inner sub-apical margin, distally with setae and macrosetae as illustrated; sensory field with 24 trichobothria on basal rosettes.
