200 NATURA SOMOGYIENSIS gensis Wei & Nie, 1998. (M ALAISE 1944, WEI and LIN 2005, WEI 1997, WEI and N IE 1998). Differences: E. birmana Malaise has head behind the eyes parallel, only the first tergite with triangular membraneous blotch, only base of tibiae are white, tarsi are partly white, clypeus and labrum are black. The new species has head clearly but moderately contracted behind eyes, tergites 2 and 3 with triangular membraneous spot, tibiae are dominantly white, tarsi are entirely black, clypeus and labrum are entirely white. E. formosana Mai. has head strongly contracted behind eyes, 3rd and 4th tergites without triangular spot only with white margin, sternites with broad white band, basal % of all femora are white. In the new species, head only moderately contracted behind eyes, abdominal tergites 2-3 with large white triangular spot, femora are entirely black, sternites without broad white margin. E. megocula Wei has only 7 serrulae, teeth of serrulae small without prominent, large frontal tooth. The new species has 9 serrulae, each serrulae with outstanding, large tooth. E. tibialis Wei has base of femora white, head strongly narrowed behind the eyes, lancet with 6 serrulae, basal tergites without triangular spots, serrulae without large prominent tooth. In the new species, head moderately contracted behind eyes, abdominal tergites 2-3 with large white triangular spot, femora entirely black, lancet with 9 serrulae, each serrulae with outstanding, large tooth. E. zhejiangensis Wei and Nie has serrulae minute, without large prominent tooth, The new species has each serrulae with outstanding, large tooth. The densely punctured head and thorax, the very short occipital carina and serrulae make the species distinct from other known species of the genus. Asiemphytus brunneus spec. nov. (Figs.: 4, 7B and 10D) Material. — Holotype, male. (RMNH: " S. Vietnam, Dak Lak, Chu Yang Sin N. P., nr. river, c. 740 m, 1-10. vi. 2007, C. van Achterberg and R. de Vires") Male (Fig. 4).

Antennal segments sligthly compressed, apically gently dilated. Antennal length subequal with
