Longistyla viraktamathi sp. nov.

( Figs 1–19 )

Male. Uniformly pale brown with basal triangles of scutellum black ( Figs 1–2 , 5–6 ).

Male genitalia. Pygofer ( Fig. 9 ) lobe without processes, arms of anal collar expanded distally. Subgenital plates ( Figs 9, 10 ) slightly curved dorsally, without marginal setae. Style ( Fig. 11 ) curved dorsally at nearly 45° angle, apophysis gradually narrowed to acute upturned apex, lacking setae. Connective ( Figs 12–13 ) without dorsomedial keel. Aedeagal shaft ( Figs 14–16 ) laterally compressed and broad basally then strongly curved dorsally and tapered to apex with short projection on each side at apex, gonopore apical, small.

Female. Similar in overall coloration to male, but slightly darker ( Figs 3–4 , 7–8 ). Second valvula ( Figs 18–19 ) short, of uniform width except apically gradually narrowed to acute apex with dorsal margin serrated, subapex bearing approximately 8 teeth along dorsal margin.

Measurements (mm). Male: body length 5.1, face length 1.45, width 1.73; distance between ocelli 0.53; distance from ocellus to eyes 0.25; medial length of pronotum 0.68, width 1.5; scutellum length 0.85, width 1.05. Female: body length 5.75–5.95, face length 1.55–1.57, width 1.85–1.87; distance between ocelli 0.62–0.63; distance from ocellus to eyes 0.3–0.32; medial length of pronotum 0.69–0.74, width 1.63–1.65; scutellum length 0.98–1.0, width 1.2–1.25.
