sp. nov. include spring-fed brooks in the western slopes of the Golan Heights, with shallow running waters upon basalt bedding. Little is known about the seasonality of this species as it has been rarely collected. Mature nymphs were collected in the spring and early summer (late March to June). Interestingly, the examined specimens were collected mainly in 2014-2019, and despite continuing research and much effort in the same sites, the species was not collected in 2020-2021, an observation that may indicate inter-annual fluctuations in population sizes. However, the species is very rare even in positive sampling event, suggesting that further research is needed for estimation of meta-population structure and stability.
