Eulichas jakli Hájek , sp. nov.

( Figs. 22 View FIGURES 13 – 24 , 42 View FIGURES 25 – 44 , 62 View FIGURES 55 – 64 , 82 View FIGURES 81 – 84 )

Type locality. Indonesia, southern Kalimantan, Kandangan district, 17 km NE of Loksado.

Type material. Holotype 3 ( NMPC), labelled: “ INDONESIA / S. Kalimantan / Kandangan district // 17 km NE Loksado / 15.11.[19]97/15.1.[19]98 / St. Jákl lgt [printed]”.

Description. Habitus elongate, fusiform. Body colouring brown. Pale part of setation consists of recumbent brownish-yellow setae covering uniformly head, pronotum and ventral part, and forming typical ocellations on elytra ( Fig. 22 View FIGURES 13 – 24 ).

Measurements. Male: 21 mm.

Head punctation consists of sparse moderately large setigerous punctures. Antenna long, slender, last antennomere filiform with apical elongation, 4.71 times as long as wide ( Fig. 42 View FIGURES 25 – 44 ), its ventral side smooth.

Pronotum trapezoidal, ca. 1.95 times as wide as long. Sides almost straight with indistinct obtuse angle behind the middle, hind angles prominent ( Fig. 62 View FIGURES 55 – 64 ). The disc convex. 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 of the same length as parameres. Parameres broad, with twisted apex; their distal part relatively long. Median lobe narrowly lanceolate, exceeding parameres ( Fig. 82 View FIGURES 81 – 84 ).

Female. Unknown.

Differential diagnosis. E. jakli sp. nov. could be easily distinguished from all other species of the E. fasciolata complex based on small body length, the very thin and long last antennomere, and characteristic shape of aedeagus with long distal part (between apex and subapical hook) of parameres.

Distribution. So far known only from the type locality in southern Kalimantan, Indonesia.

Etymology. The new species is dedicated to its collector, my friend Stanislav Jákl (Praha, Czech Republic), a specialist on Cetoniidae .
