Diagnosis. Males of this species can be separated from others in the genus by the distinctive semi-equally branched superior appendages.
Description. Head, body and wings light brown, abdomen paler ventrally; wings similar to those of W. stuarti ( Fig. 7 View FIGURES 7 – 11 ), length of forewing: male 2.4–2.8 mm, female 2.6–2.9 mm. Wing venation: forewing length nearly 3.5 times width; each with forks 2, 3, 4 and 5 present; fork 2 relatively short, fork 2 footstalk relatively very long, length about 2.0–3.6 times length of cross-vein r -m, length of fork 2 about 1.4–2.0 times length of fork 3; fork 3 short, length of fork 3 about 0.6–1.1 times length of footstalk, footstalk of fork 3 very long, length about 3.6–4.3 times length of cross-vein m. Hind wing length about 4.3 times width, each with forks 2, 3 and 5 present, all relatively short; fork 2 footstalk relatively long, length about 2.8–3.0 times length of crossvein r -m.
Male. Tergum X membranous with 2 lobes ( Fig. 14 View FIGURES 12 – 20 ), and ventrally directed intermediate process forming large apical spine (hidden in lateral views by ventral branches of superior appendages) ( Fig. 12 View FIGURES 12 – 20 ). Superior appendages branched, each with 2 semi-equal branches, inner dorsal branch with few apical spines on mesal lobe and single long spine on the outer lobe, outer ventral branch with 3 robust, spine-like setae apically ( Figs 12–14 View FIGURES 12 – 20 ). Phallus simple, tube-like ( Fig. 12 View FIGURES 12 – 20 ). Inferior appendages slightly depressed, fused in basal half, with pair of robust digitiform processes apically, separated widely in apical half by mesal split ( Fig. 13 View FIGURES 12 – 20 ); in lateral view slender, tapering slightly and upturned apically ( Fig. 12 View FIGURES 12 – 20 ).
Female. Genitalia with abdominal sternite VIII relatively broad, basally with robust, mesal process, tapered to apical point; segment IX relatively short, broad-based, tapered slightly distally, segment X relatively long, relatively robust with 1 pair of small cerci ( Fig. 46 View FIGURES 45 – 53 ).
