Type species, Gongrosargus stuckenbergi Lindner, 1959 , by original designation. Dinosargus Lindner, 1968 : 9 . Type species, Dinosargus lateritius Lindner, 1968 , by monotypy. Syn. nov. Gongrosargus glaucus (Bigot) . Afrotropical: Madagascar. Sargus ? glaucus Bigot, 1859 : 134 . HT? [MNHN, lost]: Madagasgar: Nossi-Bé. Gongrosargus distinguendus Lindner, 1966b : 11 . ST 1 ♀ [MNHN]: Madagascar : Andranofotsy; ST 1 ♂ [MRAC], 1 ♀ [SMNS]: Madagascar : Maroantsetra. Syn. nov. The type specimen of Bigot’s Sargus glaucus is lost and the species is treated under Ptecticus in the world catalog ( Woodley 2001: 212 ). From the description, we can place this species clearly in the genus Gongrosargus , because of the description of the thorax, being green with three brown stripes, the scutellum being black at the base and green at the apex, and the hind tarsi having a black basitarsus and the rest being white. This combination of characters is not found in any Ptecticus species from Madagascar , which are all uniformly brown or dull yellow, but fits perfectly with G. distinguendus Lindner 1966 , with which we are synonymizing it. We have studied all syntypes of G. distinguendus , the male syntype from MRAC is pictured in Fig. 18 . Gongrosargus flavipennis (Macquart) . Comb. nov. Sargus flavipennis Macquart, 1838 : 200 . HT ♂ [MNHN]: Madagascar. Ptecticus flavipes: Loew, 1860 : 77 . Incorrect subsequent spelling. We have studied the male holotype [MNHN] ( Fig. 19 ), and the species fits well with the concept of Gongrosargus . Gongrosargus lateritius (Lindner) . Comb. nov. Dinosargus lateritius Lindner, 1968 : 9 . HT ♂ [MNHN]: Madagascar: Ivondro. We have studied the male holotype [SMNS] ( Fig. 20 ), and the species fits well with the concept of Gongrosargus . Gongrosargus limbatus (Macquart) . Comb. nov. Sargus limbatus Macquart, 1838 : 201 . HT ♂ [MNHN]: Madagascar. We have studied the male holotype [MNHN] ( Fig 21 ), and the species fits well with the concept of Gongrosargus . This species might be conspecific with G. stuckenbergi , but because of the poor condition of the holotype and we know of several undescribed species close to G. stuckenbergi , we are not formally synonymizing the two species. Gongrosargus pallidus (Macquart) . Comb. nov. Sargus pallidus Macquart, 1838 : 202 . ST 1 ♂ [MNHN], ♀ [ MNHN , lost]: Madagascar . Gongrosargus univittatus Lindner, 1966b : 12 . ST 1 ♀ [MNHN], 1 ♀ [MRAC]: Madagascar : Famponambo. Syn. nov. Gongrosargus exclamationis Lindner, 1968 : 11 . ST 1 ♂ [ SMNS ]: Madagascar : Ivondro, ST 1 ♂ [ MNHN ]: Madagascar : Fort Dauphin ; ST 1 ♂ [ MNHN ]: Madagascar : Mt. Tsaratanana , Andampy , 750 m . Syn. nov. We have studied the male syntype of Sargus pallidus [MNHN] ( Fig. 22 ), and the species fits well with the concept of Gongrosargus . The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 232) . Lindner likely never checked Macquart’s types. He considered S. pallidus to belong in “ Chrysochroma ” rather than Gongrosargus , because in Lindner’s collection [SMNS] there are two males of Ptectisargus punctum ( Lindner, 1968 ) misidentified under the name Gongrosargus pallidus . Ptectisargus punctum has the same color pattern (yellow-orange with a black stripe on the thorax) as G. pallidus , but has a clearly different wing venation. When Lindner described G. univittatus ( Fig. 23 ), he did not compare it with G. pallidus , because he did not consider them congeneric. We examined both female syntypes (MNHN, MRAC) [ Woodley (2001: 191) stated incorrectly that the “holotype” was in Paris], and they are both conspecific with G. pallidus . Only two years later Lindner (1968) described G. exclamationis ( Fig. 24 ) without comparing it to G. univittatus . We examined two of the three male syntypes of G. exclamationis [MNHN, MRAC] and they are all conspecific with G. pallidus . We have at least three undescribed Gongrosargus on hand, which have a color pattern similar to that of G. pallidus from Madagascar.
