Hagneia kallea sp. nov.

( Figs 1–68 )

Etymology. Specific epithet derives from Classical Greek κάλλος, ~εος kallos, ~eos meaning good, beauty, noble.

Diagnosis. Only one species in the genus. Male: dorso-posterior angle of pygofer with process oriented dorsad; female: pregenital sternite medially with 2 separated processes at posterior margin.

Description. Total length 0.8–1.3 cm.

HEAD. Vertex: proportion A/B = 9.6–11.25; all margins slightly elevated; in dorsal view, lateral margins almost straight and parallel; anterior margin widely arcuate, posterior margin with major curvature than anterior one.

Frons: proportion C/E = 1.25–1.32; proportion D/E = 1.43–1.5; upper margin straight, lateral margins weakly arcuate, distinctly curved to frontoclypeal suture in lower part. Frontal disc delicately rugose vertically, near the frontoclypeal suture concave; lateral carinae of disc parallel to lateral margins (in some specimens weakly visible). Frontoclypeal suture widely arcuate. Clypeus with short median carina present in median part, surface of clypeus in median part weakly convex. Rostrum reaching mid coxae.

THORAX. Pronotum: proportion F/B = 2.3–2.75; disc of pronotum delicately rugose; anterior margin widely arcuate; posterior margin weakly concave.

Mesonotum: proportion G/F+B = 6.5–6.85, proportion G/F = 9.04–9.5, proportion G/H = 1.12.–1.19.

Tegmina: proportion I/J = 1.41–1.47. Hind wing ScRA with 3 terminals, MP with 2–3 terminals, CuA wit 7–11 terminals.

MALE TERMINALIA. Dorso-posterior angle of pygofer with process oriented dorsad; posterior margin in 3/4 straight, in 1/4 convex (lower part).

FEMALE TERMINALIA. Pregenital sternite with posterior margin medially with 2 separated processes.

COLORATION ( Figs 1–5 ). Frons black with dark yellow lateral margins and narrow band alongside lateral margins. Clypeus and postclypeus medially dirty brown, lateral areas black; lateral part of head black with yellow narrow band alongside anterior margin and dark yellow patch around base of antenna. Compound eyes with irregular black and brown patches. Vertex black with lateral margins and narrow band alongside, lateral margins brown, pronotum (lateral lobes black with brown margin), mesonotum and tegulae black. Tegmina black with white tearshaped patch in middle and white-yellowish triangular patch near of end of costal area and huge transverse band alongside posterior margin. Hind wing with brown transverse band subapically posterior margin. Pro- and mesofemur on external and internal lateral side black, dorsally brown, pro-, mesotibia and tarsomeres brown. Metafemur, metatibia and metatarsus brown. Abdomen (male and females) black with brown narrow (dorsally) anterior margin (in females band bigger) of the tergites, ventral side of pygofer brown; terminalia black.
