Janak). N o t e s: This species was described ( BORDONI 2002 ) from Doi Suthep, near Chiang Mai , in North Thailand , on the basis of a female preserved in the Naturhistorisches Museum of Berlin. So far the male was unknown, therefore I figure the labrum (fig. 1), usually an important systematic character, and I propose a short description of the male genital characters: tergite of the genital segment very narrow and extended (fig. 2), sternite as in fig. 3; aedeagus of big size ( 2 mm long), extended, with sinuate lateral sides, asymmetrical parameres and internal sac rolled ribbon-like, covered by very small and sparce scales (fig. 4). This is the smallest species of the genus known so far (body 15-19 mm long).
