Material from other countries examined: 175 wor- kers and 6 gynes (CZW, NHMW) from Sri Lanka, India (Nicobar Isl.), Malaysia (Peninsular), Indonesia (Nias, Su- lawesi, Irian Jaya), Papua New Guinea, Samoa, and New Caledonia.
Description of worker: Measurements: worker with smallest HW: CI 83, HL 1.97, HW 1.63, MdI 53, MdL 1.05, MsL 2.43, SI 108, SL 1.77, PnW 0.87, PtH 0.75, PtL 0.64, PtW 0.38, TL 7.63; worker with largest HW: CI 82, HL 2.52, HW 2.07, MdI 53, MdL 1.33, MsL 2.93, PnW 1.13, PtH 0.89, PtL 0.99, PtW 0.52, SI 106, SL 2.20, TL 11.06.
Structures: Mandibles short and stout, with very fine denticles, sometimes completely edentate but always with three apical teeth (intercalary tooth slightly shorter than apical and subapical teeth). Apex of mandibles with some setae. Mandibles mostly smooth, some fine ridges / striae may occur, with fine white pubescence, hair pits distinct. Head in dorsal view rectangular, longer than wide, broad- est at level of eyes which do not surpass outline of head. Dorsum of head striate, striation almost reaching nuchal carina (at dorsal margin, area of about the width of the scape, smooth). Eyes located dorsolaterally in first third of head. Mesosoma elongate in dorsal view, broadest at level of pronotum. Pronotum with round striation, often slightly oval or longitudinal in centre, but some entire circles al- ways visible in dorsal view. Mesonotum and propodeum with transverse striation (slightly coarser on propodeum). Mesopleuron smooth in centre, some striation at margins. Metanotal spiracle inconspicuous, situated dorsolaterally. Petiole short and straight, conspicuously "tear-shaped" in
160
-------------------------------- page break --------------------------------
frontal view, broad with short petiolar spine, posteriorly flat with transverse striation. Gaster rounded to oval; an- terior part of first tergite evenly convex in lateral aspect, without impression; first tergite smooth, second with some reticulation, at least anteriorly.
Pilosity: Fine white semi-appressed pubescence on en- tire body, very dense on appendages including petiole, on mesosoma, head and gaster distance between hairs approxi- mately their length. Few standing setae on pronotum, sev- eral standing hairs on gaster increasing in length towards apex of abdomen. Some isolated hairs on head venter and one pair of standing setae on head dorsum.
Colour: Body, including all appendages, dark brown (al- most black in some specimens).
Description of gyne: Measurements: gyne with smal- lest HW: CI 87, HL 2.27, HW 1.97, MdI 57, MdL 1.30, MsL 2.93, PnW 1.60, PtH 1.00, PtL 0.78, PtW 0.49, SI 107, SL 2.10, TL 9.88; gyne with largest HW: CI 85, HL 2.47, HW 2.10, MdI 54, MdL 1.33, MsL 3.13, PnW 1.65, PtH 1.02, PtL 0.88, PtW 0.61, SI 104, SL 2.18, TL 10.31.
Structures: Differs only in the following characters: pro- notum with transverse striation, mesonotum with longitudi- nal striation, scutellum shiny, sexual female morph-speci- fic characters (wing insertions, mesosoma and gaster big- ger).
Notes: Odontomachus simillimus HNS can be easily recog- nised even in the field by small size, dark colour, propor- tionally large head and short scape. In the Philippines, there is no other species with a short, truncate subapical tooth of the mandible (Fig. 43), and none with fine reticulation on visible part of gaster tergite 2 (but note that the anterior part of tergite 2 which is usually covered by tergite 1 is also reticulate in other species).
Odontomachus simillimus HNS is surprisingly uniform over its large distribution area. It is distinguished from the sec- ond Old World species, O. troglodytes HNS from Africa, Ma- dagascar, and the Seychelles, by its smooth gaster tergite 1.
Distribution (Philippines: Fig. 47): Widely distributed from India to Polynesia (Wilson 1959, Brown 1976), "un- doubtedly many of the island records represent accidental introductions by man" (Brown 1976: 87). No distribution limit in the Philippines; records from 21 islands (19 in this study).
Habitats: Odontomachus simillimus HNS is a common spe- cies which also can be found in open or moderately to strongly disturbed habitats, like coastal areas, coconut groves, villages, and even lawns on university campuses. It usually does not enter dense forests, but can be occa- sionally found on banks of stream running through forests. According to collections by Chapman in eastern Negros, the species can be found from sea level up to an elevation of 900 m (Wheeler & Chapman 1925).

Type material:
Odontomachus simillimus Smith HNS , 1858 : 80 [ 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 HNS , 1915 : 239 [ 33 ]. Type locality: Christmas Island , Australia ( BMNH ) [not examined]. Synonymized with simillimus HNS by Brown, 1976: 106 [ 1 ].
Odontomachus haematodes var. fuscipennis Forel HNS 1913 : 19 [ 34 ] .Type locality: Peradeniya, Sri Lanka (MNHB?) [not examined]. Synonymized with simillimus HNS by Wilson, 1959 : 499 [ 32 ] .
Ponera pallidicornis Smith HNS , F. 1860 : 73 [ 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" (Linnaeus) 1758 which is a different species. Forel's [ 25 :159] record of "O. haematodes" 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.

Diagnosis of worker among Antkey species. Antenna 12-segmented. Clypeus with anterior margin flat to convex, but never forming a distinct triangle that projects anteriorly beyond the base of the mandibles. Posterior margin of head interrupted by median groove. Eyes medium to large (greater than 6 facets); situated distinctly below midline of head. Frontal lobes present. Mandibles linear; armed with apical fork; inserted towards the middle of the anterior head margin. Hind coxae lacking dorsal spine Waist 1-segmented. Petiole narrowly attached to gaster with conspicuous posterior face; upright and not appearing flattened; armed with apical spine. Gaster armed with sting; abdominal segment 4 lacking deep longitudinal furrows; distinct constriction between abdominal segments 3+4 or not visible between abdominal segments 3+4. Color brown to black, often with paler coxae and appendages.
Odontomachus is readily distinguished from most other genera with introduced or commonly intercepted species by its distinctive head shape and linear mandibles armed with an apical fork. Odontomachus can be easily confused with the generally smaller Anochetus, but can be separated by median groove that interrupts the posterior margin of the head. The only other introduced or commonly intercepted ponerine with long linear mandibles is Leptogenys falcigera, from which Odontomachus species can be separated by the mandibles which are inserted into the clypeus medially (versus laterally) and are armed with an apical fork, and also by the prominent apical spine on the petiole. Additional study is required to distinguish O. ruginodis from O. simillimus. The general sculpture, color, pilosity, head shape, petiole shape and even the metasternal process (Brown [1976]) are very similar. At this point the only way to distinguish them is by their respective ranges.

Smith, F.:
Female. Length 4 1/2 lines.-Resembling O. haematodes, with the following differences: the mandibles more distinctly serrated, the sulcations on the sides of the face anteriorly, not so deeply impressed, or so smooth and shining, they also terminate before reaching the ocelli; the line running from the ocelli to the posterior margin of the vertex is not so deeply impressed; the most striking difference is to be found in the neuration of the wings; the discoidal cell is of a somewhat different form, and the externo-medial nervure is straight, and unites with the transverso-medial nervure at the basal angle of the discoidal cell; in other respects it scarcely differs from O. haematodes.
Hab. Fidjee Islands; Ceylon.
The difference pointed out in the neuration of the wings would appear to indicate a generic distinction; but an examination of a number of winged females shows a frequent approach to the neuration of the present species, and in specimens of the male of haematodes, taken with the female from the same nest, by Mr. Bates, the neuration is found to be identical with that of O. simillimus ; in the British Museum are two specimens from Ceylon which appear to be identical with the present species.

Worker diagnosis: Workers and males are very similar in morphology and size to troglodytes 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' (Linnaeus) 1758 which 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. simillimus 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 .
CO1. The average within species CO1 divergence for O. simillimus 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 from 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.

Female. Length 4 1/2 lines.-Resembling O. haematodes, with the following differences: the mandibles more distinctly serrated, the sulcations on the sides of the face anteriorly, not so deeply impressed, or so smooth and shining, they also terminate before reaching the ocelli; the line running from the ocelli to the posterior margin of the vertex is not so deeply impressed; the most striking difference is to be found in the neuration of the wings; the discoidal cell is of a somewhat different form, and the externo-medial nervure is straight, and unites with the transverso-medial nervure at the basal angle of the discoidal cell; in other respects it scarcely differs from O. haematodes.
Hab. Fidjee Islands; Ceylon.
The difference pointed out in the neuration of the wings would appear to indicate a generic distinction; but an examination of a number of winged females shows a frequent approach to the neuration of the present species, and in specimens of the male of haematodes, taken with the female from the same nest, by Mr. Bates, the neuration is found to be identical with that of O. simillimus ; in the British Museum are two specimens from Ceylon which appear to be identical with the present species.
