Macropelopia
sp.
Afghanistan
Kownacki, Wojtusiak, Żurek, 1976
Larvae
undescribed.
Pupal exuvia
(n = 1),
7.5 mm
long, grayish brown, with abdominal pigmentation patterns similar to
M. nebulosa
.
Thoracic horn flattened (Figure 14 A), ± 850 µm long, covered with small scales, index of plastron plate 0.44, the lower edge of plastron plate with row of light spots, respiratory atrium narrow. Thorax with outer edge corrugated (Figure 14B).
Spines of abdominal shagreen solitary or in groups of 2 (Figure 14 E), tergites II–V with transverse posterior band consist with many, small teeth (Figure 14 F) and conjunctives II/III, III/IV, IV/V, V/VI VI/VII, VII/VIII with fine shagreen. On the tergite of II–VI segments setae D1 arise from a large, strongly chitinised tubercle (Figures 14 C, 14 E), D3 not exceptionally long. Lateral setae on I–VI segment simple, short, mounted on a small tubercle, segment VII with 6 long taeniate L setae, (Figure 14 D) VIII with 5. Anal lobe is more or less straight, with fringe setae (

Comments.
The pupa of
Macropelopia
sp. from
Afghanistan
differs from other
Macropelopia nebulosa
group species in the following features: very large tubercle on segment II–VI, seta D1 only 1.5x longer then tubercle, transverse posterior band with many, small teeth no bigger than shagreen.
