Notes. New records for Vietnamese fauna. C. haksik is a group 2 species, characterized by a very black thorax (in Chinese specimens and one male from Tam Dao) or has thorax with greyish pruinose stripes over metepisternum and lower part of mesepimeron and thin, sometimes difficult to discern, grey antehumeral stripes. Abdomen black, but for S1–2 and most of S3, which are red ( Fig. 6 C). This species is close in appearance to C. uenoi but can be distinguished based on several characters of body pattern and by the structure of appendages and genital ligula (see Diagnosis under C. uenoi ).

Distribution. Tam Dao National Park, Vinh Phuc Prov.; Pia Oac Nature Reserve, Cao Bang Prov.; Ha Giang Prov.
