Remarks.

The record from Israel (Mount Hermon) reported by Warncke (1977) is actually D. hermonensis sp. nov. (see Section 7). Dioxys pumilus is highly likely to be present in Israel given its presence in neighbouring Syria and Jordan, but this must be confirmed with verified specimens. Further to the comments made under D. cypriacus (Section 5), the concept of D. pumilus is used here much more narrowly than previous authors. The identification key and earlier comments above allow for the separation of male specimens that allow the geographic range to be clarified, as separation of females based only on morphological characters is challenging if not impossible, which is why a broad species concept for D. pumilus has been employed to date.
