Head. In full-face view oval, anterior and posterior of eyes moderately convex (Fig. 83B View Figure 83 ). In lateral view sub-rectangular; ventral and dorsal faces relatively flat; dorsal face not depressed posteriorly; inner hypostomal teeth visible. Sides of the head with sparse, short, erect pilosity; whole head with sparse, long, suberect to erect pilosity. Antennal scrobes absent; lateral sides of head shiny, foveolate with a few thin, irregular to longitudinal short rugae. Occipital lobes shiny, with fine and sparse foveolae and sparse, thick, irregular rugae, foveolae fading posteriorly; frons on the anterior part with sparse, thick, and longitudinal rugae, interspaces smooth, and posterior part with rugae thinner and more irregular, interspaces foveolate; genae shiny, with dense and thin rugulae, central part smooth; malar area with thin, longitudinal, dense rugoreticulation. Centre of clypeus shiny with indistinct longitudinal rugulae, lateral sides with longitudinal rugae; median notch present, moderately wide, and shallow; median longitudinal carina present; lateral longitudinal carinae present. Scape, when laid back, reaching the midlength of head; pilosity suberect to erect (Fig. 83B, D View Figure 83 ). Inner hypostomal teeth distinct, closely spaced, moderately low, triangular, with rounded apex directed inward; outer hypostomal teeth thinner and higher then inner hypostomal teeth, dentate, and with relatively wide base (Fig. 85A, B View Figure 85 ). Mesosoma. In lateral view, promesonotum moderately low and arched, posterior mesonotum steep, without tubercle-like projections; promesonotal groove absent; metanotal groove absent; propodeal spines moderately long, triangular, with rounded apex and wide base; humeral area laterally well produced (Fig. 83D View Figure 83 ).

Head. Occipital margin straight or indistinctly concave; occipital carina absent (Fig. 83A View Figure 83 ). Pilosity moderately sparse, moderately long, suberect to erect. Head foveolate; frons with a few indistinct, short, longitudinal rugulae. Clypeus with fine and fading foveolae; median longitudinal carina present; two lateral longitudinal carinae present. Scape, when laid back, surpassing the posterior head margin by two-fifths of its length; pilosity suberect (Fig. 83A, C View Figure 83 ). Mesosoma.

Etymology.
Malagasy for plants, in reference to nesting habits of this species.
Biology.
The species was collected between 1050-1100 m in elevation, in montane rainforest. Nests were located in rotten logs.
