Odontomachus simillimus Smith  HNS  :

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

Type material:

Odontomachus simillimus Smith, 1858: 80  HNS  [ 31]. 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]. 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.
