holotype ( CMNH, photos by Peter Schüle); 7, 9, 10 – specimens from Cambodia .

NOTES. This Vietnamese ex-endemic was originally described from a single female

(Naviuax, 1996), followed by a record of another female from not very far from the type locality (Matalin, 2002). From all similar species, N. labiosa difers well by the shape and colour of the labrum ( Figs 6–7 ) and elytral pattern ( Figs 8–10 ). The lateral portion of the median band in the holotype is reduced ( Fig. 8 ), but Naviaux (1996: 69) considers this as a case of individual variability. In the second female known from Vietnam, the lateral portion of the median band is dramatically reduced (see Matalin, 2002: fig. 2), while in both

Cambodian females the lateral portion is larger than the apical one ( Figs 9–10 ). The total length (without labrum) of the Cambodian specimens varies from 7.4 mm to 7.8 mm (vs. 7.8

mm in the holotype). Until now, N. labiosa has been known only from the Dak Lak Province of Vietnam (Wiesner et al., 2017), thus being new to the fauna of Cambodia. The new locality extends the distribution area considerably to the west. Unfortunately, the male of this species is still unknown .
