Lindner (1936) described the genus Microptecticus with M. dimidiatus as its type species, of which we have examined one of the female syntypes [SMNS]. In the same publication he described Ptecticus magnicornis and Microchrysa nigricoxa . Mason (1997a) stated that M. nigricoxa cannot be kept in the genus Microchrysa and Woodley (2001: 232) listed it under the “unplaced species of Sarginae ”. We have seen the holotypes of both species and they fit well in the concept of the genus Microptecticus, since both have the lower calypter without projecting lobe or at most with very small finger-like projection and M vein strong only distally. Microptecticus ambiguus (Fig. 25) was described as the second species in this genus by Lindner. Shortly thereafter Lindner (1968) described the third species, M. clarus, which he surprisingly compared only to M. dimidiatus and did not mention M. ambiguus at all. We examined the two female syntypes of M. clarus [MNHN] (Fig. 26) and the holotype of M. ambiguus [MNHN] (Fig. 25) and concluded that they are conspecific. We have more than 10 undescribed species of this genus from Madagascar on hand.
