Eupoa daklak sp. n. Figs 33-35

Type.

Holotype ♀ (ZMUM) from Viet-Nam, Dak Lak Prov., c. 25 km SSW of Buon Ma Thuot (c. 12°26'48"N, 107°58'E), Dak Linh, 500 m a.s.l., 28-29.04.1986, L.N. Medvedev & S.I. Golovatch.

Etymology.

The species epithet is a noun taken in apposition of the type locality: Daklak province of Viet-Nam.

Diagnosis.

The central shallow depression of the epigyne of Eupoa daklak sp. n. (Fig. 33) is unique among all the Eupoa species known to us. The male of Eupoa daklak sp. n. remains unknown.

Comments.

Although this species is described on the basis of a single female, it is highly unlikely that it could belong to one of the three other new species described below on the basis of males ( Eupoa lobli sp. n. from Malaysia; Eupoa pappi sp. n. and Eupoa pulchella sp. n. from Thailand). All Eupoa species, as well as those of two closely related genera ( Corusca and Sinoinsula ), are litter-dwellers, with most of them (except for Eupoa lehtineni sp. n.) having small, local ranges. For instance, 22 distinct species of Corusca and Sinoinsula were recently described from Hainan Island of China alone ( Zhou and Li 2013a, b). Therefore, it is safe to conclude that this and three other Eupoa species that are described herein on the basis of a single sex from very distant localities indeed belong to different species. Finally, there is no technical way to match this female with one of the males, unless they were collected together.

Coloration (Fig. 35). Carapace yellow-brown, with brownish radial veins on thorax and yellow eye field. Blackened around eyes. Clypeus naked, yellow, with a brown marginal line. Sternum, maxillae, labium and chelicerae yellow, tinged with brown. All abdomen brownish yellowish, without a colour pattern. Book-lung covers yellow, tinged with brown.
