Labial palp long and narrow, distinctly expanded apically, upper margin with eight very long, strong setae set in raised sockets (Fig. 3 d); movable hook incurved, but only ca 3 / 5 length of longest palpal seta (Figs 3 d, 5); palp terminating in broad securiform ‘ comb’ separated by shallow notch from short ventral hook slightly exceeding margin of comb in length. Mandibles brown, teeth black blown, formula: L 1 + 234 + 50 y ab R 12345 ab, molar crest absent both right and left mandibles, incisor teeth rounded, 2> 3> 5> 4> 1, additional tooth y on the right mandible (Figs 3 e – h). Maxillae long, with dense long setae present on the distal one-thirds of its length (Figs 3 i – j). Thorax. Brown, smooth without distinct bands or marks. Prothorax rectangular. Synthorax trapezoidal and elongate. Legs moderately long and slender, the femur of hind leg reaching to middle of S 4. Wing cases parallel, outer wing cases reach to the hind margin of S 4, inner cases a little shorter. Abdomen. Brown, smooth with black brown markings. Lateral spines absent. Ovipositor of female extending beyond the end of S 10 (Figs 3 k – l). Caudal lamellae half as long as abdomen, broadly paddle-shaped ending in a short white filament, especially on outer lamellae, margins with well separated low serrations; surface marked with irregular black blotches, especially visible near base. Maximum length: width ratio 2.6 in lateral lamellae and 2.4 in median lamella (Figs 3 m – n).	en	Yang, Guo-Hui, Orr, Albert G., Zhang, Hao-Miao (2022): Descriptions of the larvae of Huosoma Guan, Dumont, Yu, Han & Vierstraete 2013 from China (Odonata: Coenagrionidae).

03F3D545D966FF924089EB36FE5DF8FC.taxon	description	Measurements (mm). Larvae (N = 3), body length (excluding caudal lamellae) 12 – 13.5; length of abdomen (excluding caudal lamellae) 8 – 9; maximum head width 2.5 – 2.8; length of hind femur 3.5 – 4; lateral caudal lamella 4.5 – 5. Biological notes. The larva of H. latiloba was found in a pool in a small mountain stream, with numerous hydrophytes (Fig. 7 a). Breeding adults often appear at the edge of nearby streams (Fig. 6 c). The flight season ranges from June to September.	en	Yang, Guo-Hui, Orr, Albert G., Zhang, Hao-Miao (2022): Descriptions of the larvae of Huosoma Guan, Dumont, Yu, Han & Vierstraete 2013 from China (Odonata: Coenagrionidae).

VI. 2021, same locality, Guo-Hui Yang leg. 1 ♀ larva was successfully raised to emergence. Habitus: Generally similar to H. latiloba. Legs and wing sheaths relatively slightly longer (Figs 7 d, e) and, caudal lamellae leaf shaped, longer and narrower than in H. latiloba. Head. Comparatively large, occipital lobes gently rounded, not bulbous in dorsal view; mouthparts (Figs 4 a – i), fairly similar to H. latiloba but with relatively broader prementum, maximum breadth ca 0.78 length; length about four times wider than base; anterior margin more strongly projected as obtuse isosceles triangle, apex forming 105 ° angle (dorsal view), with fine marginal denticles; row of four long, strong setae sub-medially on upper side of prementum. Labial palp long and narrow, distinctly expanded apically, upper margin with six very long, strong setae set in raised tooth-like sockets (Figs 4 b, c); movable hook short, incurved, only ca 1 / 2 length of longest palpal seta; palp terminating in broad securiform ‘ comb’ separated by shallow notch from short ventral hook slightly exceeding margin of comb in length (Fig. 6). Thorax. Very similar to H. latiloba but legs longer; femur of hind leg reaching to hind margin of S 4; outer wing sheaths reaching just beyond hind margin of S 4, inner sheaths slightly shorter (Figs 7 d – e). Abdomen. Very similar to H. latiloba but ovipositor of female extending only to end of S 10 (Figs 4 j – k). Caudal lamellae foliate, long and narrow, more than half length of abdomen (maximum length 3.5 times width of lateral lamella and 3.2 times width of median lamella (Figs 4 l – m). Lateral lamellae white-tipped with short terminal filament, also present in median lamella but less developed.	en	Yang, Guo-Hui, Orr, Albert G., Zhang, Hao-Miao (2022): Descriptions of the larvae of Huosoma Guan, Dumont, Yu, Han & Vierstraete 2013 from China (Odonata: Coenagrionidae).

03F3D545D964FF954089ECB1FD35F9EF.taxon	description	Measurements (mm). Larvae (N = 3), body length (excluding caudal lamellae) 11.5 – 14; length of abdomen (excluding caudal lamellae) 7.5 – 8; maximum head width 2.8 – 2.9; length of hind femur 3.6 – 4; lateral caudal lamella 4.5 – 5. Biological notes. The larvae of H. tinctipenne were found in a small, heavily vegetated shallow pond in a brook at an elevation of approximately 2,550 m (Fig. 8 b). Adults were often present breeding in the same pond (Fig. 7 f). The flight season ranges from June to September.	en	Yang, Guo-Hui, Orr, Albert G., Zhang, Hao-Miao (2022): Descriptions of the larvae of Huosoma Guan, Dumont, Yu, Han & Vierstraete 2013 from China (Odonata: Coenagrionidae).
