Here what I find in the Hemiptera of Israel. II / R. LINNAVUORI / HELSINKI 1961
Dicyphus Fb. (D. tamaninii E. Wgn.) - Jericho, Transjordania, 1 spec., 12. III. 1904, J. Sahlberg ). - Holomediterranean, also recorded from the South of France, Italy, Yugoslavia and Tunisia.
D. lindbergi E. Wgn. - Dan, 4 spec., 7. VII. 1958,!. - Swept from the ground vegetation (ferns, e.g. Adianthum capillus- Veneris, Cyperaceae and Labiatae) in a dense, shady and moist grove at the source of the Jordan. - Syrio-Anatolian, previously known from Cyprus and Syria. The specimens from Israel have the vertex a little narrower than the specimens from Cyprus, but the male genitalia are similar.
D. tamaricis Pt. - Palestine (BODENHEIMER op.cit.). - Eremian; otherwise recorded only from Algeria and Tunisia. The record from Israel apparently erroneous.
D. annulatus (W.) -- Palestine (BODENHEIMER op.cit.). - Holomediterranean, also extending far into Central Europe.
D. ononidis E. Wgn. - Dan, 5 spec. 7. VII. 1958,!; Hadera, 6 spec., 1. VII. 1958,1; Hula, 3 spec., 10. VII. 1958,!; Nabi Rubin, 18 spec., 4. VII. 1958,!; Yarkon, 1 spec., 28. VI. 1958,!. - Common on Ononis species. Pontomediterranean previously recorded from Italy, Greece and Morocco.
D. sedilloti Pt. - Nahariya, 1 spec., 6. VIII. 1958,1; Wadi Sukreir, 1 spec., 27. VI. 1958!; Yarkon, 42 spec., 5. VII. 1958,!. - Common on Silene succulenta on coastal dunes. - Probably Eremian. Previously known only from. Tunisia. The Palestinian specimens agree externally with specimens from Tunisia. Unfortunately I have seen only females from Tunisia so that I have not been able to compare the male genital characters.
since the specimens was found in the coastal dunes this could be someone of the the above. interesting, regarding the connection to the Datura palnt I found this link Link maybe this can help to clear ID
I will keep looking on this bug

Some useful information, i hop
I found info regarding facultative predators according some sources is appear that Dicyphus sp. is facultative predators and (at last) some spices specialize in specific plants groups (Solanaceae/ Datura is belong to the Solanaceae
"Some facultative predators show clear preferences to feed on some crop species and cultivars, which are thus more exposed to their injury than the less preferred ones. Such is the case for D. tamaninii, which may damage tomato, but rarely French cucumber varieties." (Encyclopedia of Entomology Edited byJohn L. Capinera University of Florida Second Edition)
It's will be interesting to know if my Dicyphus is belong to this group

OK We may walk in the wrong way While searching more info about the Dicyphus I found an Article (in Hebrew) "Biological control of Bemisia tabaci in tomato cultivars with resistance to TYLCV"
This article show the possibility of Cyrtopeltis tenuis Reuter to be use as Biological control.
I have ask Google about Cyrtopeltis tenuis and BINGO I found some matching photos Link Link

Amir,
I never saw Cyrtopeltis tenuis myself but close species has nymph that look like the one in the above photo so it could be nymph of Cyrtopeltis tenuis or other close sp. |

Ciao
Yesterday I was visit the location again and search on the Datora in more deep I find mainly nymph and some adults Many seen sucking plant juices (as in the attach photo) so its clear this species is a facultative predators more about sfacultative predators can be read in the link (English) Link
