Ochrosoma Ogloblin, 1930:104, a junior homonym of Ochrosoma Herr.-Schaeff., 1854 (type species Crepidodera nigripennis Motschulsky, Ceylon, Burma, by original designation). - Chen, 1934:234, 380; 1936b:642. Ogloblinia Csiki in Heikertinger & Csiki, 1940:280 (new name for Ochrosoma Ogloblin). Gressitt & Kimoto, 1963:748, 881. - Kimoto, 1966:623. - Konstantinov & Vandenberg, 1996:322. Sphaeraltica Ohno, 1961:84 (type species Graptodera flavicornis Baly, 1874, Japan, by original designation). - Kimoto, 1966:623 (synonymized) Philaphthona Medvedev, 1993:21 (type species P. tenebrosa Medvedev, 1993, Philippines, by original designation). - Konstantinov & Vandenberg, 1996:322. (synonymized).

Distribution: Japan, southwestern China, Vietnam, Pacific Islands ?, Philippines.

Statistics: 2 species in Palearctic, 9 species worldwide.

Host Plants: Berberis thunbergii, Stephania japonica, Cocculus trilobus (Kimoto, 1965).

Comments: All the characters (antebasal transverse impression of pronotum, narrow frontal ridge, antennal calli, apical part of tibiae flat, first metatarsal segment as long as in Longitarsus species, and intercoxal part of first abdominal segment bicarinate) mentioned as unique for Philaphthona (Medvedev 1993) are very common in Ogloblinia (see diagnosis). Also examination of specimens identified as Philaphthona by L. Medvedev are in full agreement with Ogloblinia.

Diagnosis: Body small, oval, convex. Color yellow or brown to black; sometimes elytron metallic blue; pronotum reddish brown.
Head hypo-prognathous, convex from lateral view. Frontal ridge narrow, not flat, forming elevated, sinuous Y-shaped ridge with anterior margin of head capsule. Antennal calli small, oval, narrowly connected, well delineated from vertex by furrows. Interantennal space wider than diameter of antennal socket, but narrower than transverse diameter of eye. Orbital line situated very close to eye. Clypeus very long. Antenna 11-segmented, filiform.
Pronotum wide, convex, broadly explanate laterally, with shallow antebasal transverse impression. Procoxal cavity open behind. Intercoxal prosternal process more or less narrow.
Elytra oval, convex, with humeral calli. Elytral punctures irregularly placed, rarely arranged in irregular striae; interspaces narrow and flat. Lateral side of elytron sometimes with several longitudinal wrinkles. Epipleuron wide, notably tapering apically. Metasternum with posterior margin greatly swollen, covered with long erect hairs. First abdominal segments with two subparallel ridges between metacoxae.
Metatibia long, thin, enlarged apically, with flat apical 1/3. First metatarsal segment almost as long as 1/2 of tibia.
