Description. Pupa [n = 2] Total length 5.8-6.0 mm. Exuviae brown.

Cephalothorax (Figs 10A, C–E). Frontal setae 25-30 µm long, fine, arising subapically from conical, 125-150 µm long cephalic tubercles. Thoracic horn plumose, with numerous fine branches (Fig. 10E); basal ring oval (Fig. 10D). Thorax granulose dorsally, more densely granulose anteriorly. Prealar tubercle low and rounded. Scutal tubercle prominent. Wing sheath without nose; pearl row absent. Two short precorneals, 2 short antepronotals and 4 dorsocentrals present. Lengths of dorsocentrals (µm): 100-105, 80-105, 75-90, 65-90.

Abdomen (Fig. 10B, F–G). Tergite I (Fig. 10F) bare; II with posteromedian group of small points; III-VI with narrow, transverse, posterior band of robust spines; VII with a pair of anterior patches fine shagreen; VIII with a pair of anterior and posterolateral patches of shagreen. Hook row widely interrupted medially. Conjunctives bare. Pedes spurii A present on segment IV; pedes spurii B present on segment I. Sternite I (10 B) with a pair of spinose anterolateral tubercles, dark and well developed. Segment VIII without posterolateral comb or spur. Segment II-IV with 2 strong L setae situated on tubercles; V-VII with 4 LS setae, VIII with 5 LS setae.

Anal lobe (Fig. 10G) 1.75-1.94 × as long as broad, with complete fringe of 68-72 lamelliform setae. Genital sac 300 µm long, extending beyond anal lobe.

Remarks.

This species can easily be separated from other known pupa of Harnischia species by the following characters: sternite I with a pair of spinose anterolateral tubercles, dark and well developed; tergites III-VI with narrow posterior robust spines; hook row medially interrupted; segment II-IV with 2 L setae situated on tubercles; anal lobe with complete fringe of 68-72 lamelliform setae.
