Odontomachus sp. 2 (Figs. 24 - 26, 46)
Material examined (1 worker, FMNH): Mindanao: D a v a o: east slope of Mt. McKinley [a peak in the Mt. Apo massif], 1.IX.1946, 5200 ft. (= ca. 1600 m a.s.l.), on ground, leg. F.G. Werner, 1 ∑.
Description of worker: Measurements: CI 76, HL 2.90, HW 2.22, MdI 52, MdL 1.50, MsL 3.57, SI 121, SL 2.68, PnW 1.33, PtH 1.35, PtL 1.38, PtW 0.54, TL 12.38.
Structures: Striation on head strong until ocular ridge, fading out toward temporal ridge, except along median furrow smooth and shiny like posterior part of head. Striation on pronotum conspicuous: longitudinal posteromedially, horseshoe-shaped around; fine in centre, coarser towards outer margins. Mesopleuron with some longitudinal striation, smooth and shiny at centre. Petiole elongate S-shaped (posterior face concave) with long petiolar spine that is slightly bent backwards. Anterior slope of tergite 1 almost evenly convex, with sharp impression.
Pilosity: Pubescence on head and mesosoma loose, distance between hairs approximately their length. No setae on tergite 1, tergite 2 with 3 setae, setae increasing in length and number towards apex of abdomen.
Colour: Body uniformly light brown, however, possibly bleached out due to long storage in alcohol.
Distribution (Fig. 46): Mindanao: Davao.
Notes: The single worker from Davao resembles O. philippinus and O. scifictus sp.n., but striation on head and mesopleuron is more extensive, striation on pronotum peculiar. Compared to all Philippine O. infandus group species, the anterior of tergite 1 is more convex. The specimen strongly resembles some workers from the nearby island of Sulawesi, Indonesia (from Mayr's collection at NHMW, without details on locality) which belong to an undescribed species.
