Nilotonia (Dartonia) rizeensis Oezkan & Bader, 1988

Material examined: Wet mosses, Harşit Valley , Gümüşhane, 40°43'28"N, 39°02'40"E, 730 m a.s.l., 23.11.2013 (0/1/1).

Records from Turkey: Rize ( Oezkan and Bader, 1988).

Distribution: Turkey ( Erman et al., 2010; Esen et al., 2017).

Remark: This is the second record from Turkey except the type locality. To date, only the female of Nilotonia (Dartonia) rizeensis is known from Rize Province. In the collected specimens from Gümüşhane Province, a female and a deutonymph were found. The dorsal plates of deutonymph are similar with adults. There are two pairs of genital acetabulae in the genital field. Bearing a ventrodistally projection on pedipalp femur and three setae on the tip of the last segment of fourth leg are the most important characteristic features of adults. Although the general palp shape of deutonumph is similar to adults, there is no projection on P-2. Further, unlike adult individuals, there are two setae on the tip of the last segment of the fourth leg. Figure 5 A-G show some morphological details of female and deutonymph from Gümüşhane Province.
