Additional material studied. 2 specimens — INDONESIA: SUMATRA: 13 NE Sumatra, R. Taylor ( BMNH). MALAYSIA: 1Ƥ, Sungkai reserve, 1.–10.vii.1918, ex F.M.S. Museum ( BMNH).

Description. Habitus elongate, fusiform. Body colouring from brownish-red to brown. Pale part of setation consists of recumbent yellowish or yellow greyish setae forming indistinct ocellations on pronotum, and characteristic ocellations on elytra ( Fig. 15 View FIGURES 13 – 24 ).

Measurements. Males: 20–24 mm (holotype 24 mm); females: 25–30 mm.

Head punctation consists of sparse, irregularly distributed moderately large setigerous punctures. Antenna long, slender, last antennomere rather oval, with apical elongation, 2.56–3.63 times as long as wide ( Fig. 36 View FIGURES 25 – 44 ), its ventral side smooth.

Pronotum trapezoidal, ca. 1.92–1.97 times as wide as long. Sides almost regularly rounded ( Fig. 56 View FIGURES 55 – 64 ). The disc with two indistinct rounded depressions. Punctation consists of sparse fine 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, slender, slightly attenuating to subapical hook. Their subbasal hook is missing, but the subapical hook is well developed, slightly prominent. Median lobe slender, rather subparallel ( Fig. 76 View FIGURES 72 – 77 ).

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

Differential diagnosis. E. sausai sp. nov. is similar to E. serricornis sp. nov. in habitus. However, it can be distinguished at first sight by the elytral ocellations forming more or less distinct transverse fasciae. In addition, E. sausai sp. nov. has less serrate antennomeres 3–10 and shorter antennomere 11, parameres attenuating regularly to the subapical hook, and median lobe is subparallel, attenuating only in the apical third of its length.

Collection circumstances. Specimens from Malaysia were collected at light.

Distribution. The species is so far known only from several localities in Malay Peninsula and Sumatra Island.

Etymology. The new species is dedicated to one of its collectors, Ondrej Šauša (Bratislava, Slovakia), a specialist on Elateridae .
