  • Phygasia Chevrolat in Dejean, 1836:387 (type species Altica unicolor Olivier, 1808, India, by subsequent designation of Chevrolat, 1845). - Chevrolat in D'Orbigny, 1845:6. - Heikertinger & Csiki in Junk, 1939:265. - Heikertinger, 1950:45. - Gressitt & Kimoto, 1963:882. - Kimoto, 1966:621. - Scherer, 1969:112. - Medvedev, 1992:512, 587. - Konstantinov & Vandenberg, 1996:279.

  • Phygasia Baly, 1876:445, preoccupied by Chevrolat, 1836; (type species Phygasia ornata Baly, 1876, China, by subsequent designation of Mauluk, 1926). - Maulik, 1926:412.
  • Scallodera Harold, 1877a:365 (type species Graptodera fulvipennis Baly, 1874, Japan, by monotypy). - Heikertinger, 1924a:38. - Chûjô, 1936:17 (synonymized).
  • Algrisma Fairmaire, 1888:156 (type species A. externecosta Fairmaire, 1888 = P. fulvipennis Baly, by monotypy). - Chûjô, 1936:17 (synonymized).

Distribution: Russian Far East; Japan; China; India; Sumatra; Java; northern, western and central Africa; Madagascar.

Statistics: 2 species in Palearctic, more than 30 species worldwide.

Host Plants: Cynanchum macranthum (Medvedev 1992), Metaplexis japonica, Paederia scandens (Gressitt & Kimoto 1963).

Comments: According to Pope (1992) and Madge (1988) the author of Phygasia should be Chevrolat (in Dejean 1836). Maulik (1926) attributed the genus to Baly, and designated the type species, given above.

Diagnosis: Body medium sized to large, elongate to oval, more or less flat from lateral view. Color yellow, brown or black, sometimes with spots on elytron. Pronotum and elytron sometimes differently colored.
Head hypo-prognathous, oval, convex from lateral view. Frontal ridge very narrow and short, forming short, elevated, T-shaped ridge with anterior margin of head capsule. Antennal calli raised, triangular, very long, strongly delineated from frontal ridge, vertex and each other by deep furrows. Orbital line present. Antennal socket large. Interantennal space narrower than diameter of antennal socket. Eye small. Clypeus long. Antenna 11-segmented, filiform.
Pronotum wide, with widely explanate lateral margin and with transverse and longitudinal impressions basally. Procoxal cavity open behind. Intercoxal prosternal process narrow and long.
Elytra wide, oval, more or less flat, irregularly punctate, with well developed humeral callus; lateral margins broadly explanate. Epipleuron wide, horizontal, not reaching posterolateral elytral margin.
Metafemur typical. Metatibia comparatively short, cylindrical, expanded apically; apex oblique. Metatarsus inserted apically. Metatarsal segments wide and short, first one shorter than following two combined.
