Head. In full-face view longer than wide, anterior of eyes straight, posterior of eyes relatively straight (Fig. 82B View Figure 82 ). In lateral view sub-rectangular; ventral and dorsal faces relatively flat; dorsal face finely depressed posteriorly, forming shallow transverse depression between frons and occipital lobes; inner hypostomal teeth visible. Sides of the head with moderately sparse, long, erect pilosity; whole head with dense, short, suberect to erect pilosity. Antennal scrobes indistinct and not delimited by carinulae; scrobe surface shiny, with thick, longitudinal, and long rugae; interspaces smooth to indistinctly rugulose. Occipital lobes shiny, with thick, irregular rugae, interspaces with distinct, irregular rugulae fading posteriorly; frons with moderately dense, thick, longitudinal, and interrupted rugae, interspaces smooth to indistinctly rugulose; genae shiny, with sparse and thin, irregular rugoreticulation, posterior part smooth; malar area with thin, longitudinal, dense rugae. Centre of clypeus shiny and smooth, lateral sides with longitudinal rugulae; median notch present, narrow and moderately shallow; median longitudinal carina present, indistinct; lateral longitudinal carinae present. Scape, when laid back, reaching the midlength of head; pilosity erect (Fig. 82B, D View Figure 82 ). Inner hypostomal teeth distinct, moderately high, closely spaced, triangular, with rounded apex and wide base; outer hypostomal teeth thinner, smaller, and narrower than inner hypostomal teeth, dentate (Fig. 84W View Figure 84 ). Mesosoma. In lateral view, promesonotum relatively low and arched, posterior mesonotum relatively 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 weakly produced (Fig. 82D View Figure 82 ). Surface shiny, promesonotum, katepisternum, anepisternum, and dorsoventral surface of propodeum smooth, with very indistinct, short irregular rugulae, only lower part of lateral sides of propodeum with thin, longitudinal rugulae; lateral sides of propodeum shiny, with thick, longitudinal rugae. Pilosity moderately sparse, long, and erect (Fig. 82D, F View Figure 82 ). Petiole. Shiny; peduncle short, finely foveolate, with indistinct horizontal lobes on its basal part; node smooth, relatively high, triangular, with rounded apex, in rear view node slightly convex; pilosity moderately sparse and erect (Fig. 82D, F View Figure 82 ). Postpetiole. Shiny, finely shagreened, with smooth dorsum; in dorsal view sides with moderately long, acute, wide, and triangular projections; pilosity moderately long, and erect (Fig. 82D, F View Figure 82 ). Petiole. Shiny and finely shagreened; pilosity dense, moderately long, and erect (Fig. 82D, F View Figure 82 ). Colour. Black; legs brownish black (Fig. 82D, F View Figure 82 ).

Head shiny, with sparse but distinct foveolae, and additional longitudinal to irregular, thick rugae on frons and malar area, and thick, sparse, and arcuate rugae on vertex; genae and malar area smooth. Clypeus smooth, with basal part finely rugulose; median longitudinal carina present; two lateral longitudinal carinae indistinct. Scape, when laid back, surpassing the posterior head margin by one-fifth of its length; pilosity erect (Fig. 82A, C View Figure 82 ). Mesosoma.

Pilosity sparse, moderately long, and decumbent to erect (Fig. 82C, E View Figure 82 ). Petiole. Peduncle short and thin with ventral face slightly convex; with few short, erect setae (Fig. 82C, E View Figure 82 ). Postpetiole. Short, low and convex; with few short, erect setae (Fig. 82C, E View Figure 82 ). Petiole. With sparse, erect pilosity (Fig. 82C, E View Figure 82 ). Colour. Dark brown (Fig. 82C, E View Figure 82 ).
Etymology.
Greek for shiny [λαμπερός], in reference to dark and very shiny sculpture of minor and major workers.
Biology.
The species was collected at elevation between 980-1100 meters, in montane forest. Nests were located in rotten logs.
