Figs 35–41 View FIGURES 35–41
This new species belongs to the Diplectrona aurovittata-obscura-tamdaophila complex and is distinguished from the other species by having forewings lightly speckled and marbled, not patterned. In addition, the cerci are narrow; the glabrous paraproctal lobes are each bidentate, with a small, dark-pigmented, ventral tooth; the dorsoapical setose lobes of segment X protrude dorsally; and the ventroapical setose lobes are clearly visible.
Male. Body sclerites medium brown; setal warts on head and thorax lighter. Eyes without setae. Proepisternal setal wart present and swollen. Frontal lateral compact setose warts oval, horizontally elongate; single clypeal median compact setose wart; single labral anteromedian compact setose wart. Head dorsum with single vertexal medioantennal compact setose wart and 4 pairs of setose warts: narrowly elongated postgenal compact setose warts; large, ovoid, compact occipital setose warts; vertexal ocellar compact setose warts; and vertexal lateroantennal compact setose warts. Coronal, lateral vertexal, occipital and postoccipital grooves forming dark brown lines on head dorsum. Cranial areas medium brown; warts light brown.
Abdomen with pair of anterodorsal filaments on sternite V about 2 times longer than length of sternite; internal reticulated sacs in abdomen not visible absent.
Forewings brown with light speckled and marbled pattern; length 8.5 mm; hind wing apical fork I present.
Male genitalia. Segment IX short, regularly convex anteriorly, without dorsal concavity; median keel separated into 2 broad and flat ridges; short, granulose, with microtrichiae. Segment X fused to tergum IX; short, weakly sclerotized. Dorsoapical setose lobes (inner lobes) of segment X well-developed; round, broad, protruding posterodorsad in lateral view; posterior 1/3rd separated by narrow, deep dorsal interlobular gap. Ventroapical setose lobe of segment X small, distinct, with several setae visible below smaller ventral paraproctal tooth. Cerci setose, vertically elongate, narrow in lateral view. Paraprocts short, each with large, hook-shaped dorsal tooth and short vertical tooth well visible only in anterolateral view. Gonopods straight; coxopodites each with shorter apical half dilated. Harpagones narrow, arching mesad, parallel-sided, each tapering abruptly at apex. Phallic apparatus with ventrad-curving, broad basal section; apical half slightly longer, tubular, horizontal; apex bulbous in lateral view. Endothecae with 2 pairs of processes, each with blunt apex in lateral view and tapering and triangular in ventral view; dorsal endothecal processes large and strongly pigmented; ventral endothecal processes small, almost hyaline; phallotremal sclerite indistinct.
Holotype male: INDONESIA (Sumatra): Kerinci National Park , “W” waterfall, 1500 m, 5.vii.2008, light trap [J. Oláh, Jr.]—(OPC, in alcohol).
Distribution: Indonesia (Sumatra).
Etymology: Tiguna, “double” in Sanskrit, referring to the paraproct having 2 teeth.
