Redescription male ( Figs 61, 63 ). Wingspan 18–19 mm, forewing length 8 mm, antenna 6 mm, body 8–9 mm. Head with haustellum present, but relative short; scales of labial palpus relative short, distally smooth, ventrally rough; first palpomere white, ventrally brownish black; second and third palpomere brownish black, second dorsally white, third with a few white scales; frons dark grey with indistinct metallic gloss, near base of antennas slightly rough; vertex black, laterally white; pericephalic scales dorsally mixed black and white, laterally pure white; antenna clavate, flagellum black, occipetal side with proximally dense, distally scarce scaled, whitish stripe. Thorax brownish black; patagia laterally with small pinkish-red spot, that is connected with forewing base by a narrow pinkish-red stripe; posterior margin of tegula pinkish-red; dorso-lateral scale tufts of metathorax mixed brownish black and white. Abdomen brownish black with fine, white posterior margin of tergite 2 and broad, white posterior margins of tergites 4 and 5; sternites 2–7 with proximal two-thirds red; anal tuft very small, dorsally and ventrally black, laterally orange. Legs brownish black; fore leg with coxa laterally white and femur ventrally with narrow stripe of white, hair-like scales; other legs with coxa proximally white throughout and femur laterally mottled with white; tarsomeres of all legs distally whitish; spurs white. Forewing brownish black, costal margin and proximal part of anal margin pinkish-red; hindwing with proximal half hyaline; underneath of both wings paler, costal margins and basal area of forewing dusted with white.

Male genitalia ( Fig. 120 ). Gnathos absent; valva trapezoid, broadest basally, area of bifurcate setae not extend to ventral margin; phallus straight, very long.

Female ( Figs 65–66 ). Similar to the male, but labial palpus brownish black, first palpomere laterally white; antenna clavate, black, proximally dusted with white scales; tergite 2 posterior-laterally with white spot, which replaces the narrow posterior margin of the male; anal tuft reduced.

Female genitalia ( Fig. 131 ). See genus description.

Diagnosis. Both species of Hagnogyna are unmistakable and easy to determine. The typical red pattern of the otherwise black body and wings, the alternate black and red striped sternites and the white posterior margins of tergites 4 and 5 are characteristic for H. sanguicosta .
