Habitus elongate, fusiform. Body colouring from brownish-red to brown. Pale part of setation consists of recumbent yellowish or greyish setae forming indistinct ocellations on pronotum, and characteristic ocellations on elytra ( Fig. 6 ). Measurements. Males: 21–26 mm ( holotype 23 mm ); females: 25–31 mm . Head punctation consists of irregularly distributed sparse moderately large setigerous punctures. Antenna robust, last antennomere nearly rectangular, 2.17–2.44 times as long as wide ( Fig. 30 ), its ventral side smooth. Pronotum trapezoidal, ca. 1.87–2.00 times as wide as long. Sides skewed and straight in anterior half, then with obtuse angle, and prominent hind angles ( Fig. 50 ). Pronotum with two oval shallow depressions on the disc, and indistinct depressions also medially along anterior and posterior margin. Punctation consists of rather irregularly distributed sparse moderately coarse setigerous punctures. 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, relatively broad, their sides attenuating sinuously to subapical hook. Parameral subbasal hook small, but the subapical hook is well developed. Median lobe lanceolate ( Fig. 70 ). Female. Similar to male in habitus, but larger. Antenna shorter, and more slender. Differential diagnosis. E. similis sp. nov. is almost identical with E. jendeki in habitus. It differs from that species in the shorter last antennomere, sinuous inner side of paramere, and lanceolate median lobe of aedeagus. The short last antennomere and lanceolate median lobe distinguish E. similis sp. nov. also from another similar species E. siamensis sp. nov. Collection circumstances. Collected at light. Distribution. A species occurring in the upland area of northern Thailand and Laos . Etymology. The Latin word for “similar” refers to its similar appearance with other Eulichas species, in particular with E. jendeki .
