Odontomachus simillimus Smith   HNS   :

Figures: worker 12a,b, 13b; queen 12c,d; male 12e,f;

Type material:

Odontomachus simillimus Smith, 1858: 80   HNS   [ 31] View Cited Treatment . Type locality: Fiji Islands [not examined]. Junior synonym of haematodus   HNS   by Roger, 1861: 24 [ 26]; revived from synonymy by Wilson, 1959: 499 [ 32].

Odontomachus haematoda var. breviceps, Crawley, 1915: 239   HNS   [ 33]. Type locality: Christmas Island, Australia ( BMNH) [not examined]. Synonymized with simillimus   HNS   by Brown, 1976: 106 [ 1].  

Odontomachus haematodes var. fuscipennis Forel 1913: 19   HNS   [ 34].Type locality: Peradeniya, Sri Lanka (MNHB?) [not examined]. Synonymized with simillimus   HNS   by Wilson, 1959: 499 [ 32].

Ponera pallidicornis Smith, F. 1860: 73   HNS   [ 35] View Cited Treatment . Type locality: Makassar, Celebes ( BMNH) [not examined]   . Synonymized with simillimus   HNS   by Brown, 1976: 106 [ 1].

Worker measurements: maximum and minimum based on n = 10 from Madagascar: HL 2.33-2.63, HW (across vertex) 1.64- 2.03, HW (across upper eye margin) 1.77-2.06, CI 75-81, EL 0.20-0.23, ML 1.14-1.28, MI 48-51, SL 2.16-2.43, SI 109-123, WL 2.62-3.06. FL 2.29-2.56, PW 1.02-1.24.

Queen measurements: maximum and minimum based on n = 5 from Madagascar: HL 2.37-2.55, HW (across vertex) 1.79- 2.03, HW (across upper eye margin) 1.87-2.13, CI 79-84, EL 0.49-0.53, ML 1.17-1.30, MI 49-52, SL 2.15-2.38, SI 111-118, WL 3.13-3.19. FL 2.36-2.58.

Male measurements: maximum and minimum based on n = 1 from Madagascar: HL 0.89, HW 1.19, CI 133, EL 0.59, SL 0.19, SI 16, WL 2.44. FL 1.73.

Worker diagnosis: Workers and males are very similar in morphology and size to troglodytes   HNS   Bivariate plots of metric measurements did not distinguish the two species. 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   HNS   " (Linnaeus) 1758 which is a different species. Forel's [ 25:159] record of " O. haematodes   HNS   " from Seychelles, Mahe most likely refers to simillimus   HNS   .

Found in clearings and secondary growth throughout the IndoPacific. The records from the Seychelles clearly represent an introduction. O. simillimus   HNS   is not known from Madagascar and may have difficulty in establishing on Madagascar because of the presence of the morphologically and ecologically similar O. troglodytes   HNS   .

CO1. The average within species CO1 divergence for O. simillimus   HNS   was 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. simillimus   HNS   from the ecologically similar O. troglodytes   HNS   , the two species are, on average, 7-8% divergent within the CO1 barcode.

Diagnostic barcoding loci. O. simillimus   HNS   : C-265, T-267, T- 528.
