( Figures 10–15 )

Description

Body length including wings: male 5.1 mm, female 5.1–5.2 mm.

External characters as in S. transvittata but ocellocular distance about three times diameter of ocellus and pronotum slightly shorter than crown with anterolateral margins straight and slightly oblique.

Male pygofer with lateral lobe broadly produced, apical area with long macrosetae, apical margin with three spine-like processes; aedeagal shaft sinuate in antero-posterior aspect with a pair of elongate apical processes directed ventrally, basal apodeme with a long lamellate process from each basal arm extending beyond apex of aedeagal shaft; connective Y-shaped; style pincer-shaped apically with subapical lobe very long, tapered apically and apical process strongly curved laterally.

Female terminalia as in S. transvittata but posterior margin of seventh sternum almost straight.

Body and forewing milky-white, ocellus light yellow, eyes light brown, face without spots. Scutellum with dark spots at basal corners. Forewing with three fine oblique bands subapically on anterior margin, a blackish brown spot at base of second apical cell, apex of clavus and at middle of posterior margin and apical area of wing and a wide band at median area of clavus, light brown. Thorax with venter yellowish white, without spots, claws black.

Sophonia yunnanensis is similar to S. albuma but has the forewing with a black spot apically on the clavus and an oblique wide band on the medial area. The two species also clearly differ in the structure of the male genitalia.
