Diagnosis.
Major workers. Head in full-face view sub-oval; sides of the head with dense, long, erect pilosity; occipital lobes shiny, with thick, irregular rugae, interspaces with distinct, irregular rugulae not fading posteriorly; inner hypostomal teeth distinct, high, closely spaced, triangular, with rounded apex directed inward, and wide base; outer hypostomal teeth taller and wider than inner hypostomal teeth, lobe-like, directed outward; gaster smooth. Minor workers. Head shiny, foveolate, with additional short, longitudinal, thick rugae on frons, genae with fading sculpture and smooth notch; scape, when laid back, surpassing the posterior head margin by one-fifth of its length; promesonotum low, convex, short, with posterior declivity smoothly declining towards propodeum; mesosoma foveolate, katepisternum smooth; propodeal spines short, triangular.

In lateral view sub-oval; ventral and dorsal faces convex; dorsal face not depressed posteriorly; inner hypostomal teeth visible. Sides of the head with dense, very long, erect pilosity; whole head with moderately dense, long, suberect to erect pilosity. Antennal scrobes indistinct and not delimited by carinulae; scrobe surface shiny, with thick, longitudinal, and long rugae; interspaces distinctly rugulose. Occipital lobes shiny, with thick, irregular rugae, interspaces with distinct, irregular rugulae not fading posteriorly; frons with moderately dense, thick, longitudinal rugae, interspaces smooth, with indistinct rugulae weakening anteriorly; genae shiny, with dense and thin, irregular rugulae, central part with smooth notch; malar area with thin, longitudinal, dense rugae, interspaces with distinct rugulae. Centre of clypeus shiny and smooth, lateral sides with longitudinal rugulae; median notch present, narrow, and moderately deep; median longitudinal carina present, indistinct; lateral longitudinal carinae present. Scape, when laid back, reaching the midlength of head; pilosity erect (Fig. 39B, D View Figure 39 ). Inner hypostomal teeth distinct, high, closely spaced, triangular, with rounded apex directed inward, and wide base; outer hypostomal teeth taller and wider than inner hypostomal teeth, lobe-like, directed outward (Fig. 84X View Figure 84 ).

Head. Occipital margin straight or indistinctly concave; occipital carina absent (Fig. 39A View Figure 39 ). Pilosity moderately sparse, moderately long, suberect to erect. Head shiny, foveolate, with additional short, longitudinal, thick rugae on frons; genae with fading sculpture and smooth notch.

Peduncle short and thin with ventral face slightly convex; with few short, erect setae (Fig. 39C, E View Figure 39 ). Postpetiole. Short, low, and convex; with few short, erect setae (Fig. 39C, E View Figure 39 ). Petiole. With moderately sparse, erect pilosity (Fig. 39C, E View Figure 39 ). Colour. Yellow (Fig. 39C, E View Figure 39 ).
Etymology.
Latin for long pilosity, in reference to the very long pilosity on sides of head in major workers.
Biology.
The species was collected between 500-1100 m in elevation, in montane and gallery forests. Nests were located in rotten logs.
