(Fig. 1) Discoderes cavifrons Fairmaire 1904 : 234 (orig. desc.); Théry 1905 : 178 ; Marie & Lesne 1917 : 40 . Phlocteis cavifrons : Obenberger 1928 : 341 ; 1934: 796; Bellamy 2001b : 66 . Specimens examined. Holotype (gender indet.) (MNHN): Soalala, H. Perrier; 2 spms. (CASC): Madagascar , Bekiley, xii.1943 , det. Descarpentries. Remarks. This little species is neither a Discoderes Chevrolat, 1838 ( type species: Agrilus salzmanni Solier, 1833 , original designation) nor a Phlocteis Kerremans, 1893 ( type species: Buprestis exasperata Swartz , in Schönherr, 1817, original designation), the two genera where it has been placed in the past, as currently defined ( Bellamy 1986 , 1988a , 1988b ). No members of the former genus are known to occur on Madagascar , while two species of Phlocteis are known from the island ( Bellamy 2001a ). Discoderes is represented by two species: D. salzmanni (Solier) is known from Subsaharan Africa including records for Ethiopia , Guinea , Nigeria and Senegal is probably naturally distributed in the thorn­scrub savanna immediately below the southern boundary of the Sahara Desert. The second species, D. villiersi Descarpentries, 1952 is known only from Benin . These two species are moderate­sized coraebines, relatively elongate, flattened above, with the upper surface uniform in color, aeneneous ( D. villiersi ) to black ( D. salzmanni ) with the head only very feebly longitudinally sulcate, with the upper surface notably patterned with setal spots and short fasciae (white on D. salzmanni or cream­colored on D. villiersi ). The five species of Phlocteis differ by having both the head and pronotum with narrow, moderately elevated gibbosities, four on the frontovertex.
