In this paper, we provide the detail structure of the superior appendages of the species and also some variations in thorax colour of the mature male. The additional characters of the superior appendages also confirm by Xu on the holotype male and accepted by him. | HỘI NGHỊ KHOA HỌC TOÀN QUỐC VỀ SINH THÁI VÀ TÀI NGUYÊN SINH VẬT LẦN THỨ 4 DRAGONFLY COELICCIA MINGXIENSIS Xu, 2006 (ODONATA: PLATYNEMINIDEA) FROM TAM DAO NATIONAL PARK WITH ADDITIONAL NOTES ON ITS MORPHOLOGY DO MANH CUONG, NGUYEN QUANG THAI Military Institute of Hygiene and Epidemiology BUI MINH HONG Hanoi University of Education The genus Coeliccia is one of the largest genera of the family Platycnemididae, consisting of more than 60 species in Asia. In Vietnam, there were 12 species of this genus found for Vietnam’s fauna. Since Asahina’s paper published in 1997, there are some additional and modification notes on the genus of Vietnam. One species, C. tomokunii Asahina 1997 was synonymized with C. scutellum; the other species, C. yamashakii recorded by Do and Dang (2007) was misidentified by authors and confirmed as C. scutellum and C. yamashakii had been discovered in Phu Quoc Island, 2009 (Do, 2011–unpublished). The genus should be reviewed because the morphological characters of the genus based on wing venation (anal bridge vein) is not valuable. Probably this genus should be split to be several genera or at least two genera if use structure of the penis organ. However, this work may only be completed after all species of the genus treated. Number of the species of the genus recorded and discribed around South East Asia (as well as Vietnamese fauna) still is increasing every year, this is an evidence that to review this genus is rather complicate. The species C. mingxiensis was first recorded from Tam Dao National Park in 2009 in the forest stream habitat. The materials were examined and compared with the original description and also confirmed by Xu Qi-han, the author of the species. Xu (2006) described the new species C. mingxiensis based on a single teneral male specimen that collected from Mingxi, Fujian, China. However, in the description of the male holotype, Xu missed a characters of structure of the superior appendages. Hence in this paper, we .
