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.
