Chaetocladius fedotkin Makarchenko et Makarchenko, 2013: 390 , Figs. 1–3 View FIGURES 1 – 13 ; Makarchenko et al. 2014: 424.

Remarks. This species was described from the Amur River basin for adult male only. Below we describe pupa of this species.

Material. 1 mature pupa of male, Russian Far East, Jewish Autonomous Region, Obluchie District, Lopatinskyi Spring of Bidzhan River basin (Amur River basin), N 48°37' 810'', E 131°39' 114'', 2.IV. 2016, leg. E. Makarchenko GoogleMaps .

Pupa (n=1). Total length 4.7 mm.

Cephalothorax. Frontal apotome with 2 setae 84 µm long. Antepronotum with 2 median and 1 lateral antepronotals ca 80 µm long. Thoracic horn 224–240 µm long and 24–28 µm wide in basal 1/4, with large spinules, namely in distal 3/4; in basal 1/4 spinules located in lesser degree ( Figs. 14–15 View FIGURES 14 – 18 ). Precorneal setae hair-like, arranged as triangle, 60–64 µm long. Dorsal surface of thorax little roughened. Dorsocentrals broken off. Distance between Dc1 and Dc2 84 µm; between Dc2 and Dc3 96 µm; between Dc3 and Dc4 12 µm.

Abdomen. Tergite I without shagreen. Tergites II–VIII uniformly covered with shagreen spinules of one size and with 1–2 rows of larger spines near posterior edge, longest of which 4.4–5.3 µm; anal lobes with not numerous spinules ( Fig. 39 View FIGURES 34 – 39 ). Sternites I–III without shagreen of spinules; sternite IV with small spinules along posterior edge in middle part; sternites V–VII covered with small spinules, size of which large near posterior edge; sternite VIII uniformly covered with shagreen spinules of one size; sternite IX without shagreen. Segment I with 2 pair of hairlike lateral setae. Segments II–VII with 3 pairs of strong lateral setae on small tubercles and 1 pair weak hair-like setae. Segment VIII with 2 pairs of strong lateral setae on small tubercles and 1 pair with weak hair-like lateral setae. Anal lobe 320 µm long, with 3 spine-like macrosetae; anterior macroseta (AM1)112 µm long and 8 µm wide; middle macroseta (AM2) 132 µm long and 10 µm wide; posterior macroseta (AM3) 116–124 µm long and 8 µm wide. Location of anal megasetae illustrated in Fig. 39 View FIGURES 34 – 39 . Male genital sac extending 40 µm beyond anal lobe.
