Strumigenys canina

The hunting behaviour of S. canina was investigated by Masuko (1984). See Hunting Tactics in Short-Mandibulate Strumigenys for more about this ant's hunting behavior.

Identification
Bolton (2000) - A member of the Strumigenys sauteri-group. Fully described and figured by Brown & Boisvert (1979), this is the most derived member of the group. S. canina is instantly distinguished from all others in the group by its relatively long narrow mandibles (MI 19-22) and unique dentition (see discussion of sauteri-group, above). On the masticatory margin tooth 5 from the base is by far the longest and broadest, easily visible in full-face view even when the mandibles are fully closed. The anterior clypeal margin is broadly, shallowly but evenly concave in full-face view. In the other three species (Strumigenys arges, Strumigenys brontes, Strumigenys sauteri) together the mandibles are much shorter (MI 6-10), the fifth tooth from the base is not markedly the longest and broadest on the masticatory margin, and is not conspicuous in full-face view when the mandibles are fully closed. The anterior clypeal margin in these species is deeply and quite narrowly concave, the concavity usually appearing deeply semicircular with a pronounced anteriorly projecting anterolateral angle at each side of the concave area.

Distribution based on Regional Taxon Lists
Oriental Region: Vietnam. Palaearctic Region: China, Japan, Republic of Korea.

Biology
Masuko (1984) observed and reported on what he called "body smearing behavior" in S. membranifera and other Strumigenys species (see Strumigenys behavior).
