Camponotus hemichlaena

Identification
This species is distinguished from Camponotus obscuripes by its black pronotum (pronotum red in C. obscuripes). It was originally described as a subspecies of C. obscuripes and later raised to species rank by Yasumatsu & Brown (1957). However, since no other morphological distinctions have been observed between it and C. obscuripes, separation from obscuripes depends exclusively on coloration. Further study on its taxonomic status is needed. Both C. hemichlaena and C. obscuripes are present in Shikoku and Kyushu, Japan, with obscuripes tending to be at higher elevations. On Honshu, C. hemiclaena is known only from Hiroshima. (Japanese Ant Image Database)
