. The reassessment, based on external and sting characters, added five apomorphies supporting the subfamily: lateral blunt teeth on genae, metatibial gland absent, gonostylus fused to the posterior arm of the oblong plate, several microtrichia plus two longer sensillae at the presumed junction of gonostylus with posterior arm of oblong plate, and base of sting shaft with a pair of long setae. Brandao, Diniz et al. (l. c.) also established several apomorphies for both leptanilloidine genera. For

, five apomorphies were established: postpetiole extremely reduced in size with spiracle at midlength, spiracular plate median connection of the sting apparatus with bilobed anterior region, quadrate plate apodeme wider than body of the plate, fulcral arms absent, and basal ridge of sting not visible. Recently, Longino (2003) described a new species,

workers using molecular data. Ward (l. c.) also discussed the molecular similarities of leptanilloidines to other dorylomorphs and the evolution and morphological convergences of ant assemblages living in subterranean habitats (see also Ward 1994; Lopez et al. 1994; Brady &amp; Ward 2005). Brandao, Silva et al. (1999) review some aspects of the biology of this subfamily, including observations suggestive of nomadic habits.

<paragraph id="18507EDBE16B80E53B61CF7F053BF23D" pageNumber="27">Worker description. Color light reddish-brown, with yellowish appendages. Head and mesosoma finely covered by continuous, vermiculate rugae, transverse on anterior portion of pronotum, grading to longitudinal on rest of promesonotum, mesopleura and lateral surfaces of propodeum; mandibles with few and short longitudinal striae restricted to basal portion; petiole and postpetiole irregularly rugose. Abundant pilosity on head and dorsum of promesonotum; petiolar node with about six long hairs; dorsum of postpetiole with more than 10 long hairs; first tergite of gaster with long flexuous hairs restricted to the most anterior portion, near the insertion of postpetiole.</paragraph>
<paragraph id="2D635231CCC0C59D79FFD5368ECC006D" pageNumber="27">Head slightly longer than broad, with vertexal margin only moderately convex; frontal lobes weakly rounded laterally; eyes comparatively large, with approximately eight facets at greatest diameter. Promesonotum gently convex in profile; metanotal groove relatively narrow and deeply impressed; propodeal spines mostly straight, with apexes minimally directed upwards; teeth of propodeal lobes swollen basally, with about half-length of propodeal spines. Petiolar node elevated and subtriangular in dorsal view; dorsum of postpetiole strongly convex and with a discrete anteroventral projection, directed anteriorly.</paragraph>
