Description. Habitus elongate, fusiform. Body colouring brownish-red to brown-blackish. Pale part of setation consists of recumbent yellowish setae forming typical ocellations on pronotum, elytra and abdominal sternites, where setae are darker and sparser (Fig. 68).

Measurements. Males: 18–25 mm (holotype 20 mm); females: 25–26 mm.

Head punctation consists of coarse setigerous punctures. Antenna robust, last antennomere ca. 1.73–1.93 times as long as wide ( Fig. 46 ), its ventral side smooth with numerous small tubercles.

Pronotum largely transverse, ca. 2.00–2.27 times as wide as long, sides almost regularly rounded. The disc convex. Punctation consists of fine setigerous punctures, distributed sparsely on the disc, and somewhat densely laterally.

Elytra with numerous longitudinal rows of large setigerous punctures, and very fine interstitial punctures.

Ventral part with fine punctures, which are sparse medially and become larger and denser laterally. Last abdominal ventrite laterally regularly rounded to apex.

Male. Aedeagus with phallobase longer than parameres. Parameres simple, their subapical hook well developed, but the subbasal hook is reduced to a short protruding carina. Median lobe lanceolate, with subbasal spines turned dorso-laterally ( Fig. 30 ).

Female. Habitually similar to male, but on average larger. Antenna shorter and more slender.

Differential diagnosis. The new species differs from other species of the E. jaechi species complex by the slender elongate habitus, last antennomere short and broad without apical elongation, and by shape of the aedeagus, which has the subbasal parameral hook reduced to a short carina, and a lanceolate median lobe.

Collection circumstances. Collected at light.

Distribution. Known from several localities in Cameron Highlands, Malay Peninsula.

Etymology. The new species is named after the type locality “Tanah Rata” in Pahang District, Malaysia. The noun is used in apposition.
