longitudinal veins. Moreover, there are two small, but distinct dark spots at the median thickenings. In the female terminalia (Figs 43A-C) gonapophyses laterales missing, or perhaps they are fused, and represented by the hairy knob at the caudal end of the pump structure of bursa copulatrix. The pump structure heavily sclerotized, with two lobes; one of them wide, with strong teeth basally, while the other one thorn-like, with or without chitinous teeth. Other parts of bursa copulatrix moderately sclerotized, large; ductus seminalis long, narrow, and starting at the caudal part of pump structure. Receptaculum seminis and its duct very weakly sclerotized, with - at least - a few spines in the spermatheca. (Larger part of this organ was not investigable because of gut content.) Remarks - Because of the same pattern of the coloration of the antennae, the new species seems to be very close to H. monserrati Sziráki, 2001, which was collected in Dalat (southern part of Vietnam). The main distinctive features of//, acuticauda are: - the scape less elongated, while the pedicel relatively larger than in H. monserrati since in latter species the scape 4 times as long as broad, and also 4 times as long as pedicel, while pedicel (in lateral view) 1.5 times as long as broad, and only 2 times as long as the second flagellar segment; - frons and occiput distinctly lighter than the head capsule behind the eyes, while in H. monserrati the whole head capsule light brown. Moreover, it is worth to mention the indistinct brown colour of the wing membrane, with light strips and the measures of the new species are smaller. Besides, the new species was collected from bamboo at an elevetion about 150 m a.s.L, while H. monserrati from pine trees in 1800 m a.s.l.
