Eulichas haucki Hájek , sp. nov.

( Figs. 24 , 40 , 61)

Type locality. Thailand, Loei Prov., Phu Kradung Nat. Park.

Type material. Holotype ɗ ( NMPC), labelled: “ THAI [ Thailand], NE, Loei prov., Phu / Kradung N.P., 1000m / 16°52’N, 101°49’E, 16– / 17.v.1999, D.Hauck leg. [printed]”.

Description. Habitus elongate, fusiform. Body colouring dark brown. Setation consists of dominant recumbent light brown setae covering most of dorsal surface, thus the colouration of the body seems to be paler than the colour of integument, and grey setae form ocellations on the pronotum and elytra (Fig. 61). On the abdominal sternites, whitish setae predominate over brown ones.

Measurements. Male: 21 mm.

Head punctation consists of moderately large setigerous punctures. Antenna robust, last antennomere 2.05 times as long as wide ( Fig. 40 ), its ventral side smooth with numerous small tubercles.

Pronotum transverse, 2.32 times as wide as long. Sides almost regularly rounded. Dorsal surface convex. Punctation consists of moderately large setigerous punctures, distributed sparsely on the disc, and densely laterally.

Elytra with numerous longitudinal rows of large setigerous punctures, and very fine interstitial punctures.

Ventral part almost uniformly densely punctured with fine punctures. Last abdominal ventrite laterally regularly rounded to apex.

Male. Aedeagus with phallobase longer than parameres. Parameres simple, narrowed in basal fourth of their length and than widened again to apex. Parameral subbasal hook well developed, but the subapical hook is very small. Median lobe very slender, subparallel ( Fig. 24 ).

Female. Unknown.

Differential diagnosis. Eulichas haucki sp. nov. can be easily recognised by the bicoloured light brown and grey body setation, and by the characteristic shape of the aedeagus. The parameres of this species are constricted in the basal quarter of their length, and then widened again to apex. Their subapical hook is very small.

Collection circumstances. Collected at light.

Distribution. So far known only from the type locality in north-eastern Thailand.

Etymology. The new species is dedicated to its collector, my friend David Hauck (Brno, Czech Republic), a specialist on Alleculinae .
