Description. Habitus elongate, fusiform. Body colouring brown. Pale part of setation consists of recumbent yellowish or greyish setae covering uniformly head, pronotum and ventral part, and forming rather indistinct ocellations on elytra ( Fig. 24 ).

Measurements. Male: 24–27 mm (holotype 26 mm); females: 29–33 mm.

Head punctation consists of sparse moderately large setigerous punctures. Antenna long, slender, last antennomere almost filiform, 3.80–4.44 times as long as wide ( Fig. 44 ), its ventral side smooth.

Pronotum trapezoidal, ca. 1.87–2.00 times as wide as long. Sides almost straight, with indistinct sinuation behind the middle, hind angles prominent ( Fig. 64 ). The disc convex with two lateral and one basal shallow depression. Punctation consists of sparse moderately coarse setigerous punctures on the disc, which become slightly coarser and denser laterally.

Elytra with numerous longitudinal rows of moderately large punctures, and fine interstitial setigerous 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 shorter than parameres. Parameres slightly narrowed in the middle, with twisted emarginated apex. Median lobe lanceolate, slightly constricted before apex; exceeding parameres ( Fig. 84 ).

Female. Similar to male in habitus, but larger. Antenna shorter, and more slender.

Differential diagnosis. The new species is very similar to E. fasciolata . However, E. villosa sp. nov. is sligthly smaller and more slender, with denser body setation; antennomeres are slender and more elongate. In addition, E. villosa sp. nov. differs in the shape of aedeagus: parameres are slightly narrowed medially, their subapical hook is less prominent; median lobe is more slender, slightly constricted before apex.

Distribution. So far known only from several mountain localities in Sabah, Malaysia.

Etymology. The Latin word for “villose” refers to peculiar dense body setation of the species.
