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.

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
.
