Type species, Ptectisargus lucidus Lindner, 1968 , by monotypy. Ptectisargus abditus (Lindner) . Comb. nov. Ptecticus abditus Lindner, 1936 : 37 . HT ♀ [ SMNS ]: Madagascar : Bekily. Chrysochroma laetum Lindner. 1966b : 7 . HT ♂ [ MNHN ]: Madagascar : Sakaraha. Syn. nov. Ptectisargus lucidus Lindner, 1968 : 3 . ST 4 ♂ , 1 ♀ [ MNHN ] ; 1 ♂ , 1 ♀ [ SMNS ]: Madagascar : Bekily. Syn. nov. We examined the female holotype of Ptecticus abditus [SMNS] ( Fig. 27 ), the male holotype of Chrysochroma laetum [MNHN], and two male syntypes of Ptectisargus lucidus [SMNS, MNHN] ( Fig. 28 ), and we consider all of them conspecific. FIGURES 25–30. Stratiomyidae habitus and head. 25. Microptecticus ambiguus Lindner , female holotype [MNHN]. 26. Microptecticus clarus Lindner , female syntype [MNHN]. 27. Ptecticus abditus Lindner , female holotype [SMNS]. 28. Ptectisargus lucidus Lindner , male syntype [SMNS]. 29. Chrysochroma cingulatum Lindner , female holotype [MNHN]. 30. Chrysochroma keiseri Lindner , male holotype [MNHN]. Ptectisargus brunneus (Lindner) . Comb. nov. Ptecticus brunneus Lindner, 1936 : 38 . HT ♀ [ SMNS ]: Madagascar : Andreba. We have studied the female holotype [SMNS], and the species fits well with the concept of Ptectisargus . The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 230) . Ptectisargus cingulatum (Lindner) . Comb. nov. Chrysochroma cingulatum Lindner, 1968 : 5 . HT ♀ [ MNHN ]: Madagascar : Mt. Tsaratapana , 1400 m . We have studied the female holotype [MNHN], and the species fits well with the concept of Ptectisargus . The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 230) . Ptectisargus flavifrons (Lindner) . Comb. nov. Chrysochroma flavifrons Lindner, 1968 : 6 . HT ♀ [ MNHN ]: Madagascar : Ranomafana. We examined the female holotype of Chrysochroma flavifrons [MNHN] and this species fits well with the concept of Ptectisargus . The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 231) . Ptectisargus flavomarginatus (Loew) . Comb. nov. Chrysonotus flavomarginatus Loew, 1857 : 263 . ST ♀ [ NHRS ]: Mauritius . We did not examine the type of this species, but the description by Loew fits specimens collected in Madagascar very well. The narrow elongated abdomen, lower calypter with a very elongated projection and the color pattern place this species in the genus Ptectisargus . The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 231) . Ptectisargus gracilipes (Lindner) . Comb. nov. Ptecticus gracilipes Lindner, 1936 : 40 . HT ♀ [ SMNS ]: Madagascar : Andreba. We examined the female holotype of Ptecticus gracilipes [SMNS] and this species fits well with the concept of Ptectisargus . Ptectisargus keiseri (Lindner) . Comb. nov. Chrysochroma keiseri Lindner, 1966b : 6 . HT ♂ [ MNHN ]: Madagascar : Montagne d’Ambre. We examined the male holotype of C. keiseri [MNHN] and this species fits well with the concept of Ptectisargus . The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 231) . The type series of Ptectisargus lindneri James is mixed and the male “ Allotype ” [BMNH] is conspecific with P. keiseri , while the female holotype [BMNH] is a different species. The female holotype is from the dry SW of Madagascar , while the male is from nearly the opposite corner of Madagascar , from the NE, which has a very different climate, and therefore it is not a surprise that the two specimens belong to different species. The holotype of P. lindneri has dark brown wing veins, a brown scutellum and the hind tibia being dark brown on the basal third and white on the apical 2/3 and the hind tarsi are dark brown, while P. keiseri has orange brown wing veins, a green metallic scutellum and the hind legs all light brown. Ptectisargus longestylum (Lindner) . Comb. nov. Chrysochroma longestylum Lindner, 1966b : 8 . ST 1 ♂ [MNHN], 1 ♂ [MRAC]: Madagascar : Ahitsitondrona. We examined both male syntypes of C. longestylum [MNHN, MRAC] and this species fits well with the concept of Ptectisargus . The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 231) . Ptectisargus punctum (Lindner) . Comb. nov. Chrysochroma punctum Lindner, 1968 : 6 . HT ♂ (stated ♀ ) [ MNHN ]: Madagascar : Rogez , Forêt Côte Est . We examined the male holotype of C. punctum [MNHN] and this species fits well with the concept of Ptectisargus . The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 232) . Ptectisargus ranohira (Woodley) . Comb. nov. Chrysochroma ptecticoides Lindner, 1966b : 5 . ST 2 ♂ , 1 ♀ [ MNHN , NMB , SMNS ]: Madagascar : Ambato-Boeni and Ranohira . Preoccupied , primary homonym of Chrysochroma ptecticoides Lindner, 1935 . Chrysochroma ranohira Woodley 2001 : 232 . New name for Chrysochroma ptecticoides Lindner, 1966b . We examined a male syntype of C. ptecticoides [MNHN] and a female syntype [SMNS] and this species fits well into the concept of Ptectisargus . The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 232) . Ptectisargus unicolor (Lindner) . Comb. nov. Chrysochroma unicolor Lindner, 1968 : 7 . HT ♀ [ MNHN ]: Madagascar : Ivondro. We examined the female holotype of C. unicolor [MNHN] ( Fig. 32 ) and this species fits well with the concept of Ptectisargus . The species was listed under the “unplaced species of Sarginae ” in Woodley (2001: 232) .
