A Lamington National Park Record implies that M. leae is sympatric there with the Metapone tillyardi.

Identification

Keys including this Species

Distribution

Taylor and Alpert (2016) - Known only from two rain-forested habitats in extreme S.E. Queensland. Probably present also in N.E. NSW, depending on the distribution of termite host species.

Distribution based on Regional Taxon Lists

Australasian Region: Australia (type locality).

Description

Queen

Taylor and Alpert (2016) - (Smallest Lamington N.P. specimen, lectotype): TL: 7.05, 6.93; HL: 1.48, 1.56; HW: 1.15, 1.18; CI: 78, 76; CpL: 0.58, 0.58; CpI: 39, 37; MSL: 2.15, 2.29; ScW: 0.99, 0.98; PetL: 0.49, 0.52; PetW: 0.50, -; PetH: - , 0.58; PpetL: 0.51, -; PpetW: 0.61, -; PpetH: -, 0.68; GW: 1.16, 1.14. The three head-intact ANIC paralectotypes have HW values 1.16–1.19 and CI values of 72–75, and the second Lamington N.P. specimen has HW 1.14, CI 76.

General and diagnostic features as illustrated and keyed here, and in Wheeler’s detailed (1919b) description and figures. Readily identified in the key to Australian species above. M. leae is one of the most peculiarly recognizable of all known Metapone species by virtue of its uniquely flattened head and mesosomal profiles, laterally directed clypeal denticles, unusually constituted petiolar node (with the dorsum raised well above the level of the posterolateral denticles, the latter posterolaterally directed, and the posterior border in dorsal view between the denticles narrowly, medially convex and bilaterally concave, and the very reduced subpetiolar configuration. These characters will, we expect, be present also in the worker caste. The frontal carinae are densely translucent, so that in full frontal view the antennal bases can be faintly seen beneath.

Type Material

Taylor and Alpert (2016) - Gyne: Tamborine Mountain [27S, 153E], Queensland.

Specimens from the type series (syntypes, labelled as “cotypes” by Wheeler) have been examined from the following collections: ANIC (7 specimens on 4 pins), MCZC (2; 1), USNMNH (1). Wheeler reported 22 specimens in the original series. All but one of the ANIC examples are damaged or fragmentary. One of the MCZC specimens is here designated lectotype, and the remaining specimens paralectotypes (all appropriately labelled). An intact type-compared Lamington National Park specimen is illustrated. It was originally alate. Its wings were removed to facilitate photography, and are card-mounted on the specimen pin.
