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.
