Head: Measurements in dorsal view, around 0.36 mm wide (compound eyes included), 0.21 mm wide (vertex); epicranial suture faintly visible; no ocelli, large compound eyes globulous, semi-circular in dorsal view, 0.14 mm long, protruding with a width of 0.07 mm; left antenna almost complete, with 15 antennomeres preserved, shorter than body length; mouthparts unclear due to specimen distortion, fractions in amber and mirror effect, maxillary palp four-segmented, labial palp two-segmented, lacinia present (Fig. 1C). Thorax: mesonotum and metanotum almost of equal length, both 0.30 mm long; wing buds visible on both thoracic segments; tibiae slender, setose with two apical spurs; all tarsi two-segmented, ratio of basal to apical segment: in fore and mid legs 1:1, in hind legs 1.8:1, basal tarsomere with two apical spurs, apical tarsomere bearing claws with one preapical tooth (Fig. 1D), without empodium or pulvillus. Abdomen: ten segments visible, with multiple glandular structures clustered mainly along the edge of each abdominal segment (Fig. 2); epiproct apically rounded, with seven long spurs; two lobe-like structures bearing one short spine each (paraprocts?); genitalia not fully developed, but of female type, with two distinct structures bearing long and thick spines apically (Fig. 3).
