( Figs. 13 View FIGURES 13 – 24 , 34 View FIGURES 25 – 44 , 54 View FIGURES 45 – 54 , 74 View FIGURES 72 – 77 )

Type locality. Thailand, Nan prov., Ban Bo Klua env.

Type material. 3 specimens — Holotype 3 ( NMPC), labelled: “ THAILAND 13.–26.V.2002 / NAN Prov. / BAN BO KLUA env. / P. Prûdek & M. Obořil leg. [printed]”. Paratypes: 2ƤƤ (nos. 1–2), same data as holotype ( NMPC).

Description. Habitus elongate, fusiform. Body colouring from brown to brown-blackish. Pale part of setation consists of recumbent yellowish grey setae forming characteristic ocellations on pronotum, elytra and abdominal sternites ( Fig. 13 View FIGURES 13 – 24 ).

Measurements. Male: 23 mm; females: 27–28 mm.

Head punctation consists of sparse, irregularly distributed moderately large setigerous punctures. Antenna long, slender, last antennomere nearly rectangular with apical elongation, ca. 3.65 times as long as wide ( Fig. 34 View FIGURES 25 – 44 ), its ventral side smooth.

Pronotum trapezoidal, ca. 1.81–1.90 times as wide as long. Sides almost regularly rounded ( Fig. 54 View FIGURES 45 – 54 ). 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 of the same length as parameres. Parameres simple, slender, parallel sided, with relatively short apical part. Their subbasal hook is missing, but the subapical hook is well developed and prominent. Median lobe lanceolate, slightly exceeding parameres ( Fig. 74 View FIGURES 72 – 77 ).

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

Differential diagnosis. In habitus, E. oborili sp. nov. is similar to E. siamensis sp. nov. and E. similis sp. nov. of the E. uniformis complex, but it is more elongate and subparallel. It could be easily recognised by the shape of aedeagus. E. oborili sp. nov. has slender, parallel sided parameres without subbasal hook, and distinctly lanceolate median lobe exceeding the apex of parameres.

Collection circumstances. Collected under the bark of tree with fermenting sap, near a stream (M. Obořil pers. comm., 2005).

Distribution. So far known only from the type locality in northern Thailand.

Etymology. The new species is dedicated to one of its collectors, my friend Martin Obořil (Brno, Czech Republic), a specialist on Buprestidae .
