Male. Holotype. Figs 105-115 . Measurements (mm): body length = 9; forewing length = 5.

Black, brown, yellow.

Brown: clypeus, dorsal flagellum, scape, LaSt 2, legs but yellow parts, apical lobes of 7 th tergum and lateroterga. Underside of flagellum and veins of the wing are light brown.

Yellow: large irregular spot on clypeal disk, apex of Tsa, two lateral spots along fore- border and a large subapical stripe on N 1 disk, tegula and humeral palate with basal veins, ape x of femurs, most of tibiae, the whole of tarsi, large (more than half the heigth of the element) apical stripe with waving fore profile on 1 st to 6 th terga, two lateral apical spots on 2 nd to 6 th sterna.

Well impressed p. on the head and mesosoma, more often well spaced with interspace among them larger than their diasmeter; weaker p. on vertex, genae and Es 2 where some smooth areas exist. Em3 with few strong wrinkles extending to anterolateral P; dorsal and declivitous P deeply and densely corrugated; very sparse p. on the metasoma, a little denser on the basal areas of the metameri and on 7 th tergum. Whitish hair throughout.

Tsa largely fused to form a ledge above Ssa, with a broad shallow median hollow at their base. Base of hypostomal carina quite prominent upon genal bridge area. Large laminated keel along the fore border on N 1, ending in an acute prominent anteroventral tooth; in the specimens from Turkmenia the broad groove along it comes broken in the upper portion by two ridges delimiting a sort of a slightly protruding platform. Propleurae strongly protruded in acute subconical processes. P with a distinct, well produced horizontal area medially severed by a deep rough groove; its posterior area is concave and almost vertical. Lateral apical lobes of the St 3 flattened with enlarged tips. Thin lobes of the epipygium (7 th tergum).

V a r i a b i l i t y In the Specimens from Kirghizistan and Kazahkistan the broad groove bordering the laminated keel on N 1 is regularly developed, with very weak transversal ridges. The shape of metasternal lobes is somehow variable, but always with enlarged tips. The size varies from 7,5 to 9.5 mm. A little variability occurs in the yellow patterns too.

Female. Unknown.

E c o l o g y: Unknown.

D i s t r i b u t i o n: Turanic region.

D e r i v a t i o n o m i n i s: From the provenance area.

D i s c u s s i o n: These specimens are well distinct from P. ciliata and P. rugosopunctata by the shape of head in frontal and dorsal aspect, the shape of N 1 in dorsal and lateral aspect, different St 3, different epipygium, different volsella and aedeagus. Moreover in the latters there is an evident median notch between Tsa and the basal depression is lacking, the metasternal lobes are acutely tipped (Fig. 116), the epipygial lobes are stouter. Poecilotiphia massageta and P. sogdiana have different shape of the head, deep notch between Tsa, pronotum without any keel, short not protruding metasternal lobes, very different epipygium and genitalia. From P. nigra and P. brevicauda this taxon strongly differs in coloration, head, pronotum, 7 th tergum and hind trochanters (acutely longitudinally keeled in the formers, simply rounded here).
