Description. Habitus elongate, fusiform. Body colouring from brownish-red to black. Pale part of setation consists of recumbent yellowish or greyish setae forming typical ocellations on pronotum, elytra and abdominal sternites ( Fig. 1 ).

Measurements. Males: 21–26 mm (holotype 22 mm); females: 25–31 mm.

Head punctation consists of sparse moderately large setigerous punctures. Antenna robust, last antennomere nearly rectangular, 2.57–3.06 times as long as wide ( Fig. 25 ), its ventral side smooth.

Pronotum trapezoidal, ca. 1.89–2.05 times as wide as long. Sides almost regularly rounded ( Fig. 45 ). 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, relatively slender, their subbasal hook small, but the subapical hook is well developed and prominent. Median lobe narrowly lanceolate ( Fig. 65 ).

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

Differential diagnosis. The new species is similar to E. jendeki in habitus, while its aedeagus is rather close to that of E. dudgeoni . Eulichas alesbezdeki sp. nov. differs from E. jendeki in the almost regularly rounded sides of pronotum and the slender and slightly attenuating parameres of aedeagus, and from E. dudgeoni in shorter last antennomere and distinct body ocellations.

Collection circumstances. Collected at light.

Distribution. Known from several localities in north-eastern Laos, and “ Tonkin ”, northern Vietnam. Etymology. The new species is dedicated to my friend Aleš Bezdĕk (České Budĕjovice, Czech Republic), specialist on Scarabaeoidea, with my special thanks for giving me the first Eulichas specimen and stimulating my interest in this family.
