A broad species, pale yellowish in colour, mottled with pinkish orange. Face of head yellowish mottled with pink, or pale yellow mottled, to a varying extent, with black. Crown, either of equal length with the eyes, or slightly longer in the centre, yellowish, mottled with orange-pink. Pronotum concolorous with the crown. Scutellum yellow or pinkish, sometimes with small black, lateral markings. Tegmen with complete venation including three crossveins, m-cu, hyaline grey with sparse irregular brown markings; veins white with orange-pink markings. An apparently constant feature is a series of small dark brown markings against the costal margin of the tegmen. Length ♀ 4.6 mm, width across eyes, 1.7 mm (Evans 1966).

Macropterous. Face and crown of head testaceous with mid brown or pinkish brown speckling. Pronotum with dark brown speckling arranged to form four to five vague longitudinal stripes. Tegmen pale translucent brown with alternating dark and pale spotting along the longitudinal veins. Male pygofer with prominent triangular tooth dorsally on posterior margin above rounded posterior lobe. Group of three macrosetae in centre of posterior lobe, cluster of short, stubby macrosetae on posteroventral corner and fine setae over apical and ventral areas. Subgenital plates broadly rounded posteriorly. Parameres with apical section serrulate, roundly emarginate apically with outer lobe longer and narrower than rounded inner lobe; basal section broadly quadrate. Aedeagus evenly curved, tapered base to apex in lateral view with preapical gonopore surmounted by pair of finely acuminate terminal processes bearing line of strong serrations on anterior margin. Female pregenital sternite with posterior margin roundly emarginate to median, short, apically emarginate prominence. Length: males 3.9 mm, females 3.8–4.5 mm. (Fletcher & Zahniser 2008).
