REMARKS. Arens (2010) recently described Hedychridium turcicum (from

Sarıkamış, Eastern Turkey) as subspecies of H. valesiense Linsenmaier, 1959 . The type series is based on a male holotype and a female paratype, collected in a different locality (Erciş, Van Province). The female interestingly shows some distinctive diagnostic features, such as genae in dorsal view with divergent angles, non typical for H. valesiense but linked to other species within the roseum species-group.

Arens (2010) suggested that this taxon has probably a distribution restricted to mountains, because it was not collected in other places where species of the roseum species-group are usually common.

The finding of some male and female specimens of H. turcicum in Siberia is not surprising and this species could be very likely a Euro-Siberian, boreo-montane chrysidid, found on the highest mountain of Anatolia as ancestral refuge population and still commonly distributed in Siberia and possibly central Asia, where distri-

butional data are not available. Based on our material, including male and female collected in the same locality, we observe that the female shows the typical shape of the head ( Fig. 14A ), with rounded posterior genae, similar to those of the male ( Fig.

15B), and the female paratype of H. turcicum could be therefore related to another possibly undescribed species. Other diagnostic characters, such as shape of scapal basin, porus, sculpture, etc. match among male and female. Taking in consideration the diagnostic characters listed by Arens (2010), as the large metallic spot on S2

(without metallic spot in H. valesiense ) and the slightly different shape of genitalia,

we consider H. turcicum as a distinct species and we here upgrade it to specific rank.

The main difference occurring between the Siberian and Turkish population is the punctuation on disc of T2, which is distinctly double in the Turkish population,

whereas simple, even and dense in the Siberian population.
