Description. Habitus elongate, fusiform. Body colouring from brownish-red to brown. Pale part of setation consists of recumbent yellow greyish, or whitish setae forming indistinct ocellations on pronotum, and characteristic ocellations on elytra ( Fig. 16 View FIGURES 13 – 24 ).
Measurements. Males: 20–24 mm (holotype 23 mm); females: 26–30 mm.
Head punctation consists of sparse, irregularly distributed moderately large setigerous punctures. Antenna long, slender, antennomeres 3–10 distinctly serrate, last antennomere filiform, 4.01–5.10 times as long as wide ( Fig. 37 View FIGURES 25 – 44 ), its ventral side smooth.
Pronotum trapezoidal, ca. 1.91–2.04 times as wide as long. Sides almost regularly rounded ( Fig. 57 View FIGURES 55 – 64 ). The disc with two oval shallow depressions. 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 very 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 simple, parallel sided, slender – the most slender in the middle of their length. Their subbasal hook is missing, but the subapical hook is well developed. Median lobe slender, rather subparallel ( Fig. 77 View FIGURES 72 – 77 ).
Female. Similar to male in habitus, but larger. Antenna shorter, and more slender.
Differential diagnosis. The new species is similar to other Malayan species of Eulichas , in particular to E. robusta sp. nov. and E. sausai sp. nov. From the first mentioned species, it differs in its smaller body size; from all species, E. serricornis sp. nov. differs significantly in the distinctly serrate antennomeres 3–10, and long, nearly filiform antennomere 11.
Collection circumstances. Most specimens were collected at light. At the locality “Batu 19” ( Cameron Highlands, Perak, Malaysia), it was found sitting on vegetation near the riverbank (ca. 6–8 m wide, mostly with sandy bottom) in mountain rainforest, at the altitude ca. 590 m a.s.l. ( Fig. 86 View FIGURES 85 – 86 ).
Distribution. So far known only from several localities in Kelantan, Pahang and Perak provinces in the Malay Peninsula.
Etymology. The name is derived from Latin words for “serrate” and “cornu” [= antenna], which refer to the characteristic shapes of antennomeres of the new species.
