( Figures 1 View FIGURE 1 ; 3p View FIGURE 3 ; 4s View FIGURE 4 ; 5x View FIGURE 5 ; 6n View FIGURE 6 )

Etymology. The species’ name refers to the acute teeth that ornate the inner side of male femora.

Type locality. Sri Lanka: Central , Kandy district, Victoria Rendenigala Ramtembe Sanctuary [07°13’ N 80°57’ E] GoogleMaps .

Distribution. Sri Lanka: Central, Kandy district ( Figure 1 View FIGURE 1 ).

Description. ( Figure 3p View FIGURE 3 ). Female unknown. Body length. ♂ holotype: 2.23 mm. Bicolor with dark head, red pronotum and red elytra marked with a broad dark area. Covered with short and dense double pubescence.

Head. Transverse, wider than pronotum, covered with white pubescence. Finely and densely punctuated. Palpi orange, last article securiform.

Antennae. Long and strong, a third longer than elytra, with antennomere 4–8 at least twice longer than wide, conical. Covered with hirsute white pubescence.

Pronotum ( Figure 6n View FIGURE 6 ). Dark red. Trapezoidal with divergent sides from base to apex, strongly convex. Sides straight. Densely punctuated, space between points smaller than the diameters of points. Covered with short double pubescence. Base sinuated with a dense fringe of golden pubescence anterior to the scutellum, half the length of the base and centered on the dorsal midline.

Elytra. Length: ♂ holotype: 1.50 mm. Dark red with a broad dark transversal area from excluding the basal third and the apical fifth of the elytra. Densely punctuated, but not as densely as on the pronotum. Space between points as large as the points themselves. Covered with double pubescence. Regularly convex.

Legs. Long and thin. Prothoracic and mesothoracic legs entirely orange, metathoracic legs dark, except base of femora dark-orange. Sexual characters: mesothoracic femora with an acute apical thorn, curved and pointing outward ( Figure 5x View FIGURE 5 ).

Aedeagus ( Figure 4s View FIGURE 4 ). Sturdy, sides regularly convex in dorsal view, ending in an apical triangle. Moderately bent near its base in lateral view, with a weak apical upward deflection.

Type material. Holotype (♂, UCDC). Sri Lanka: Central , Kandy district, Victoria Rendenigala Ramtembe Sanctuary, 07°13’ N 80°57’ E (445 m) (M. & J. Wasbauer) 23.VIII.1999. GoogleMaps
