Hyphinoe punctorum Buckton, 1903: 124 (Plate 28, figures 3, 3a), syn. nov. Remarks: Hyphinoe punctorum is proposed as a junior synonym of Eualthe punctum based on the original descriptions and illustrations. Fairmaire (1946) and Buckton (1903) characterized their respective species as having the following combination of features: an ochraceous-yellow pronotum with one pair of brown spot at each side; suprahumeral horns somewhat acute and divergent; and posterior process exceeding the apex of forewings. Buckton (1903) discussed a possible synonymy between these species, stating that Hyphinoe punctorum could be “a variety of Hemiptycha punctum ” (p. 124). Goding (1929) treated this species as Bubalopa based on his interpretation of the literature, and Funkhouser (1951) incorrectly treated H. punctorum as a synonym of B. furcata . This misidentification hindered the accurate determination of H. punctorum as well as Bubalopa and its constituent taxa.
