Sergeeva; 1♀ (ZMUM), same locality (sample-11), 6.06.1995, T. Sergeeva.

Etymology.

The species is named in honour of our colleague and friend, Dr Pekka Lehtinen (Turku, Finland), who collected the holotype.

Diagnosis.

By the conformation of the large, round tegulum, the tibial apophysis and the thin compound terminal apophysis that is hidden in the apical cavity of tegulum (Figs 26, 52), the male of Eupoa lehtineni sp. n. is most similar to that of Eupoa lobli sp. n. (Figs 60-62), but can easily be distinguished by the shape of tegular and median apophyses. The female of Eupoa lehtineni sp. n. has the easily recognizable triangle epigynal plate (Figs 29, 39-40) and the mutual arrangement and shape of receptacles (Figs 53-54).

Distribution.

From eastern India, south-eastward to Thailand and southern Viet-Nam (present data).
