Description. Pupa (n = 2). Body length 4.1–4.4 mm. Exuviae pale brown with brown abdominal apophyses.

Cephalothorax. Cephalic tubercle absent. Frontal setae 40 µm. Thorax granulate only in middle, with 8–10 rounded small beads. Prealar tubercle absent.

Abdomen ( Fig. 6C View FIGURE 6 ). Spinulation extensive on II–VII, extending onto most pleurae lateral to adhesion marks. Hook row of 18–24 hooks, 18–22% of width of segment II. Comb with 8–12 teeth. Sternite 1 ( Fig. 4E View FIGURE 4 ) with anteromedian and anterolateral weak spinule patches.

Comments. Skusella sp. ‘Sanyatang’ pupal exuviae generally resemble those of S. subvittata and S. silingae but differ in more extensive spinulation of tergites II to IV and with these pleurae being widely spinulose ( Fig. 6C View FIGURE 6 ). From S. sp. ‘Limuling’ this taxon is separated by more extensive pleural spinulation and the presence of fine spinules on sternite I.
