(Figs 29–32)
Type locality: PHILIPPINES: LUZON: CAMARINES SUR: Mt Isarog National Park, Panicuason Village, (13o 39 28.5’N, 123o 20 11.2’E).
Type deposition: Holotype: UPLB. Single Camarines Sur paratypes: ANIC, BMNH, DMGC; LACM, MCZC, UCD. Mt Makiling and National Botanic Gardens paratypes: MCZC, ANIC.
Distribution, material examined: Known only from southern Luzon, as follows. PHILIPPINES: LUZON: CAMARINES SUR: Mt Isarog National Park, Panicuason Village, (13o 39 28.5’N, 123o 20 11.2’E) holotype and 5 paratype workers (Jan Caceres, 24-x-2006, ex leaf litter); same data, dated 23-ix-06, 3 paratype workers; same data but also citing Naga City, paratype worker (R.D. Serillano, 09-viii-03); same data but also citing Naga City, paratype worker (D. General, G. Alpert et al, 13°40’11’’N, 123°19’47’’E, Nara Plantation, understory leaf litter). LAGUNA: Mt Makiling (14°08ʹN, 121°12ʹE?) 6 paratype workers (B.A. Morse, Feb 1968, rainforest berlesate, near summit). Philippine National Botanic Garden, 28 km South of Real (14o 12’N, 12o 09’E) 4 paratype workers collected together (B.B. Lowery, 4 ix. 1978, between volcanic rocks, rainforest, 300m).
This is the taxon designated Lordomyrma PH 01 by Lucky & Sarnat (2010).
Worker: General features as illustrated. Conformation of head, mesosoma, waist nodes and gaster similar to L. azumai. The head a little less expanded behind the eyes in frontal view; vertexal margin weakly convex; humeral nodules equivalent to those of L. azumai lacking; promesonotum barely raised above propodeal dorsum in profile; propodeal spines acute, relatively small, proportionately about half as long as in L. azumai. Antennal club obscurely 3-jointed. Metanotal groove with several raised transverse ribs. Pre-gastral body surfaces almost entirely reticulate-rugose, the interspaces smooth and shining, as illustrated. Incorporated traces of longitudinal striae between the antennal scrobes. Clypeus shining. Antennal foveae very finely densely punctate. Head ventrally smooth and shining. Propodeal declivity more-or-less smooth, shining, with traces of effaced transverse striae. Gaster smooth, shining, with minutely sculptured stellae at the hair bases; the surface overlain with a minutely incised microreticulum posteriorly. Exposed terminal gastral tergites similarly sculptured. Anterior coxae smooth, shining, with very faint traces of fine, transverse sculpturing. Remaining coxae and legs shining, with relatively weak traces of puncturation. Pilosity as illustrated. Color dark mahogany, the antennae and legs more lightly reddish-brown. Palpal formula Maxillary 3: Labial 2 (National Botanic Gardens specimen dissected). Dimensions (Holotype which is the largest specimen, smallest paratype (Panicuason Village): TL 3.5, 3.2; HW 0.76, 0.69; HL 0.79, 74; CI 96, 93; EL 0.16, 0.15; OI 21, 22; SL 0.55, 49; SI 71, 71; PW 0.57, 0.52; WL 1.02, 0.96; DPW 0.24, 0.21; DPpW 0.26, 0.25; GW 0.79, 0.74.
Diagnosis. Readily distinguished by its intense sculpturation, L. idianale is smaller than the similarly sculptured L. emarginata, and more closely conforms to the azumai configuration.
Etymology: Named for Idianale, the ancient Luzonese Tagalog goddess of living things.
Sympatric associations: Sympatric on Mt Isarog with L. diwata and L. emarginata.
