( Figs. 32–40 View FIGURES 32–40 )

Description. Length of male 5.8–5.9 mm.

Color ochraceous to brownish with dark brown or black markings. Forewing apex smoky or black, dark coloration occupying apical 1/2 of 3 rd apical cell and adjacent areas (Figs. 32,33).

Externally very similar to the preceding species with the following differences: slightly larger, general color darker, tending toward more brownish or dark coloring than ochraceous.

Male. Pygofer sclerotized dorsally to about midlength; somewhat elongate; excavated ventrally; gradually tapered to apex; with pair of very short medially curved spines on dorsal margin next to segment X (Figs 38,39). Valve fused to subgenital plates medially, with line of articulation with plates evident laterally; with long length of articulation with pygofer ( Fig. 40 View FIGURES 32–40 ). Subgenital plates fused basally, separate and diverging in apical half; without macrosetae; relatively slender; lobate; incised laterally ( Fig. 40 View FIGURES 32–40 ). Style with basal part and apophysis distinct from each other; apex of basal part with knob-like process directed dorsally, denticulate; apophysis strongly recurved, broad at base, attenuating to long, sharp apex ( Fig. 37 View FIGURES 32–40 ). Aedeagus with two broad shafts diverging laterally from posterior part of broad base; with pair of recurved processes arising above shafts, directed anteriorly; gonopores large, subapical ( Figs. 34–36 View FIGURES 32–40 ). Segment X sclerotized dorsally to base; sclerotized laterally, forming narrow collar ventroapically (Figs. 38,39).
