Sheela & Ghosh, 2008
Nothing is known about the biology of Lophomyrmex changlangensis.
Sheela and Ghosh (2008) - L. changlangensis comes closer to the species Lophomyrmex bedoti in the following main characters in addition to the colour: 1. The pronotal humeri only margined laterally; 2. Scape Index less than 100; 3. Propodeal spines thinner, straight and longer; 4. Mesonotum with a prominence and 5. Petiole with a narrow peduncle and a distinct high node.
Differs from L. bedoti in the following main characters: 1. In L. changlangensis distance between eye and mandibular base is 1.2x eye length (In L. bedoti distance between eye and mandibular base is > 1.5x eye length); 2. In L. changlangensis body almost bare with only three or four pairs of setae on head, thorax and pedicel (In L. bedoti body with long, erect setae all over); 3. In L. changlangensis body not shining; dull, opaque with light, indistinct punctures all over except gaster (In L. bedoti body shining with clear sculpture on parts) and 4. In L. changlangensis prominence on mesonotum high (In L. bedoti prominence on mesonotum shallow).
