Genus Loboponera Bolton & Brown (2002)

In Tribe PONERINI.

{link to the Hymenoptera Name Server} Diagnostic Features - Separable from Dolioponera by the second gastral segment with dorsum vaulted, strongly arched and down-curved posteriorly. Sternite of second gastral segment much reduced and with a bluntly U-shaped outline in profile, very much smaller than the tergite. Second gastral segment only slightly larger than first. Basal angle of mandible angulate, the apical (masticatory) margin with fewer than 8 teeth.

Listed by Belshaw & Bolton (1994b) as a new genus, with two new species, "currently being described by Prof. W.L. Brown". Finally, Bolton completed the descriptive study initiated by Brown. Thus, Bolton & Brown (2002) has seven previously undescribed species - among them the form I included and illustrated in my ant guide (Taylor, 1976) as Bothroponera species nasica group - and the incorporation of Pachycondyla (Bothroponera) nasica (Santschi).

The Bolton & Brown key is at {original description}. The new species, L. nobileae can be separated from subatra in having longer, denser pilosity on all dorsal surfaces and denser costate-rugose sculpture.
