♂, 'Vietnam, Prov. Lao Cai | Sa-pa, 1650 m | 23.ix.1963 | T. Pócs’ 'lieu herb. second. | à la lumière’ slide No. RL10762m (coll. HNHM).


Wingspan 22 mm, length of forewing 11 mm. Antennae bipectinate (apical segments also), longest male rami at mid third, maximum 10 times longer than diameter of flagellum, rami with cilia ca 1.5 as long as diameter of flagellum. Labial palps slightly longer than 5 times diameter of eyes; 3rd segment quite long and narrow, its distal half lighter; 2nd segment relatively narrow, slightly tapering. Scale-hood of vertex broad and long, triangular and apically pointed. Fore- and midtibiae densely hairy. Characteristic wing pattern features: forewing costa not concave; ground colour light brownish grey (the specimen is somewhat worn), terminal line prominent, fragmented to blackish dots, subterminal, postmedial and antemedial lines present but indistinct, slightly sinuous; reniform stigma inconspicuous, medium-sized, broad, somewhat 8-shaped, with traces of dark edge, brownish ochreous with blackish dot at bottom third and traces of a brownish line in the axis; orbicular stigma rounded with indistinct blackish edge, its colouration like that of reniform, with some dark scales in its centre. Colouration and pattern of hindwing like that of forewing.

Male genitalia (Fig. 3). Uncus medium long, straight, its basal part a densely haired, elongate, apical part evenly narrow, its tip rounded. Tegumen as long as vinculum. Saccus broad-based, long, gradually tapering, its tip rounded. Juxta large, angular. Transtilla large, broad. Saccus not visible. Valva long, medium wide, gradually tapering, but dorsal edge slightly sinuous. Valval tip slightly rounded-truncate. Sacculus with very broad but short, densely haired basal half and narrow, straight distal half connected to apical fused structure. Phallus very thick, evenly wide, straight; vesica globular, longitudinally striated with a large, straight, rounded, somewhat tongue-like cornutus.


The external appearance of Naarda pocstamasi  is similar to that of Naarda egrettoides  sp. n., but the ground colour is lighter, and the transverse lines are more prominent in Naarda pocstamasi  , making it easily recognisable. The male genitalia of this new species are very similar to those of Naarda egrettoides  , but the basal bulb of uncus is more elongate, the valva is somewhat narrower and more elongate, the costa is more sinuous, the phallus is shorter and thicker, and the cornutus is larger. In comparison with those of Naarda kinabaluensis  Holloway, 2008, the uncus is much narrower and shorter, the scaphium is much shorter, the valva is somewhat narrower and its tip is pointed instead of being truncate.


This new species is dedicated to its collector, a famous Hungarian botanist, Tamás Pócs.


Northern Vietnam.


This species appears to be the closest hitherto known relative of Naarda egrettoides  sp. n. according to the male genitalia.
