Thorax black, convex; pronotum and anterior and lateral parts of pre- and mesoscutum with golden tomentum (Fig. 1c); mesoscutum with a dark tomentose median stripe which is narrower than the vertex and ends at the transverse suture; short hair on mesoscutum yellow (2 lateral spots in front of the scutellum remain bare); 3-4 weak humeral, 2 notopleural, 1 supraalar, 2 postalar and 7-9 dorsocentral setae (4-5 dorsocentral setae in front of the transverse suture are short and weak), acrostichal setae not distinguishable from hair cover. Pleura golden tomentose, without hair; postnotal fan (metapleural tuft) yellow, composed of hair and 4 stronger setae. Scutellum black and shiny, without hair on disc and bristles on the posterior margin; metanotum with white tomentum laterally. Halter pale with brownish base.
Legs black and yellow, hair cover and bristles yellow; coxae black with golden temtentum and yellow hair; fore and mid femora black, apical third yellow; hind femur black, apical two-thirds yellow; all tibiae yellow with black tips, apex of fore tibia ventrally with small curved spur; tarsal segments black (base of metatarsus somewhat lighter).
Wings infuscated brown (by dense microtrichia), except for apical part which is whitish (Fig. 1e); costa extends round axillary cell, with black hair (yellow only at the base), alula somewhat reduced, posterior cells open and anal cell closed at the margin.
Abdomen black, rather slender like the thorax, tapering from tergite 5; without postmetacoxal bridge; tergites 2 - 5 with constricted hind margins, first tergite also with a constricted basal part (Fig. 1a); hair cover short and yellow; fine bristles at sides of the first tergite only, no discal setae; tergites shiny, except for the golden tomentose spots at the lateral hind corners of each tergite which are triangular and posteriorly wider; sternites with longer yellow hair and sternites 1 - 5 brownish tomentose. Ovipositor with acanthophorites (5 strong, brown spines at each side) and short, yellow hair.
Body length: 8,5 mm; length of wing: 6,5 mm.
Male: unknown.

Remarks to the key: Papavero (1973: 276) writes in his key to the tribes of the Dasypogoninae, that all wing cells are open in Isopogonini. Unfortunately this is not correct, because the anal cell of Paraphamartania is closed, in some specimens of P. syriaca even petiolate. Moreover he remarks that the fourth posterior cell is open or closed, not petiolate in Dasypogonini. I own some specimens of Dasypogon diadema which have the 4th posterior cell petiolate. I think this character is variable.
