Anochetus muzziolii

Identification
A member of the rugosa group. Brown (1978) defined the group: Large to medium-sized forms with single, serially dentate inner margins; mesonotal disc with a raised anterior rim; petiole bluntly pointed or narrowly rounded at apex. Male (of princeps) without pygidial spine.

Satria et al. (2017) – The species of the rugosus group differ by the following characters: Anochetus mixtus - Dorsum of head in full-face view largely smooth and shiny, but frons distinctly striate obliquely and longitudinally; mesopleuron smooth and shiny; petiolar node with its basal half weakly striate. Anochetus muzziolii - Pronotal disc smooth and shiny; mandible short (MdI < 60). Anochetus princeps - Pronotal disc smooth and shiny; mesosoma relatively slender; petiole in lateral view with a relatively long anterior peduncle. Anochetus rugosus - Head in full-face view largely striated; lateral face of head partly striated; ventral face of head smooth and shiny; mesosoma relatively short and stout; petiolar node in lateral view with anterior face sinuate and posterior face weakly convex; anterior third of mesopleuron finely sculptured; propodeum coarsely rugose; petiolar node largely coarsely rugose.
