Ledracorrhis Evans, 1959: 497 . Type species: L. rugosa Evans, 1959: 498 , fig. 6, A, B. Evans described Ledracorrhis from Madagascar. Although he stated (1959: 496) that the type specimen of L. rugosa was given by The Scientific Institute of Madagascar (l’Institut scientifique de Madagascar) to the “Muséum de Paris,” workers at MNHN have been unable to locate it (T. Bourgoin, personal communication), and it appears to be lost. Based on Evans’ description and illustrations, Ledracorrhis does not appear to belong in Ledrinae but rather in Ulopinae . Evans compared Ledracorrhis to Coloborrhis Germar and gave the following characters (translated here from the original French): ‘coarse punctation; head spatulate to projecting on the vertex; pronotum sloping anteriorly and toward the widely separated posterior projections; venation of the tegmen reticulate; the Y-shaped vein present in the clavus; the mesanepisternum a lobe on the same plane with the forewings and with the same sculpturing as the tibia; the tibia flattened; epicranial sutures present; and the spurs [Evans uses “éperons”, which translates as ‘spurs’ and might indicate the apical macrosetae] and projecting spines [row II macrosetae?] on the metathoracic tibia absent.’ He also states that it is larger in size than Coloborrhis .

Stenoledra Evans, 1954: 93 . Type species: S. decorsei Evans, 1954: 93 , figs. 10–11. Stenoledra , described from Madagascar, in dorsal view strongly resembles some petalocephalines such as Petalocephala bohemani , but is much smaller (length 6 mm). Laterally, its carinate mesanepisternum can be seen, and its broad Ushaped suture on the mesoscutum is identical to that of Coloborrhis . Apical macrosetae on the metathoracic femur and lateral macrosetae on the metathoracic tibia are absent. Its valvulae are long and slender (Pl. 19F_1). Material examined: S. decorsei : 1 female, Madagascar, MNHN, JRJ_Led1_169, 1 male, 1 female, Madagascar, ASCU, JRJ_Led1_168–169. Pl. 5K, 7H, 8D, 14F, 17H, 19F.
