Workers and queen have fine, glossy dorsal striation on head and mesosoma. Metasternal process low and rounded (Fig. 13b). Metasternal process can be viewed in mounted specimens by removing a hind leg and coxa. Brown [ 1] provides a description and additional references.  Distribution and biology. Known though most of the literature as " O. haematodes" (Linnaeus) 1758which is a different species. Forel's [ 25:159] record of " O. haematodes" from Seychelles, Mahe most likely refers to simillimus. Found in clearings and secondary growth throughout the IndoPacific. The records from the Seychelles clearly represent an introduction. O. simillimusis not known from Madagascar and may have difficulty in establishing on Madagascar because of the presence of the morphologically and ecologically similar O. troglodytes.  CO1. The average within species CO1 divergence for O. simillimuswas 3.212% with much variation between islands (Max 5.786, SE = 0.273). Importantly, although bivariate plots of worker measurements do not reliably separate O. simillimusfrom the ecologically similar O. troglodytes, the two species are, on average, 7-8% divergent within the CO1 barcode.  Diagnostic barcoding loci. O. simillimus: C-265, T-267, T- 528.  Specimens examined for Odontomachus simillimus: Additional details are provided for the specimens from Seychelles.   INDONESIA: Irian Jaya, Maffin Bay; PT.
