Nothing is known about the biology of Myrmecina kaigong.
Identification
Terayama (2009) - This species resembles Myrmecina sauteri, from Taiwan and Myrmecina ryukyuensis, from the Ryukyu Islands, southwestern Japan. However, it is distingished from sauteri by the straight anterior margin and obtusely angulate anterolateral corners of 1st gastral tergum (concave anterior margin and acutely angulate anterolateral margin in sauteri), and from ryukyuensis by the rather thick and straight, oblique rugae on head, and the smooth genal area (rugae on head thinner and much irregular, and longitudinal, and genal area microreticulate in ryukyuensis).
